This approach revealed differences in genes involved in DNA damage repair (DDR), cell cycle, and apoptosis/survival pathways (Fig. 1). The physiological relevance of these findings was then confirmed by a series of experiments demonstrating enhanced DNA damage but diminished repair due to the activation of the p53 pathway in NLRP3-sufficient DCs, suggesting that NLRP3 favors programed cell death following genotoxic stress. To examine the impact of NLRP3 on the DDR response following stimulation of DCs with MSU and H2O2, the authors

first employed single-cell gel electrophoresis, also known as a comet assay, to separate fragmented DNA from Decitabine solubility dmso whole DNA. The quantification of these data convincingly demonstrates an increase in DNA breaks in the presence of NLRP3. Next, immunoblots were performed 5-Fluoracil clinical trial to assay for H2AX histone phosphorylation on serine 139 (γH2AX), which is a hallmark of DNA damage and is required to provoke DDR. In line with the results of the comet assay, the authors found high levels of γH2AX in WT and Nlrp3−/− DCs early after stimulation, however these levels were sustained for at least 24 h in the WT samples, in contrast

to the Nlrp3−/− samples in which the levels of γH2AX decreased over time. This effect could be reproduced using rotenone or γ-radiation in place of MSU, but not when DCs were stimulated

with camptothecin, which causes DNA damage in the absence of ROS [16]. DCs lacking caspase-1 showed a similar trend to that seen in the Nlrp3−/− DCs, suggesting that NLRP3 alone is not responsible for this phenotype and a functional NLRP3 inflammasome is required. Despite the increase in DNA damage seen in WT DCs following stimulation, the authors found lower levels of 8-oxoG DNA glycosylase 1 (Ogg1) and decreased phosphorylation of NBS1, both components of the DNA repair pathway, Thiamet G in WT DCs compared with those in Nlrp3−/− DCs. These data indicate that although NLRP3 activators lead to DNA damage, the NLRP3 inflammasome is also involved in the negative regulation of the DDR pathway. To elucidate the mechanism by which the NLRP3 inflammasome may be influencing the DDR response, Licandro et al. turned their attention to the cell cycle, due to the differential gene expression they had noted in their initial array as well as the convergence of the DDR and cell cycle at discrete checkpoints [14]. Specifically, the authors sought to determine whether the p53 pathway was differentially activated in WT versus Nlrp3−/− DCs following cellular stress. Indeed, early p53 phosphorylation at Ser15 and Ser20 was noted in WT, Nlrp3−/−, and caspase-1−/− DCs, however only the WT DCs demonstrated sustained activation of p53 over time.

Padlock probes targeting the ITS region were designed and were ordered from Invitrogen Inc. (Breda, the beta-catenin inhibitor Netherlands).

To optimise the binding efficiency to target DNAs, the padlock probes were designed with minimum secondary structure and with Tm of the 5′ end probe binding arm close to or above ligation temperature (63 °C, see below). To increase its discriminative specificity, the 3′ end binding arm was designed with a Tm 10–15 °C below ligation temperature. Linker regions of species-specific probes were taken from Zhou et al. [20] and 5′ and 3′ binding arms were designed in this article (Table 2). Oligonucleotide probes (Table 2) consisted of two adjacent complementary target sequences (12–26 bp) with a spacer region (63 bp) to facilitate loop formation and to provide a template for RCA primer binding. All primers and probes were synthesised by a commercial manufacturer (Invitrogen, Carlsbad,

CA, USA). One microlitre of ITS amplicon was mixed with 0.1 μl of ampligase (5 U μl−1), 2 nmol of padlock probe, 1 μl of 10× ligation buffer, 4.9 μl of water with a total reaction volume of 10 μl. Padlock probe ligation was conducted with one cycle of denaturation for 5 min at 95 °C, followed by seven cycles of 95 °C for 30 s and 4 min ligation at 63 °C. Exonucleolysis is required to remove unligated padlock probe and template PCR product and thus reduce subsequent ligation-independent amplification events. This step seems optional in previous works,[17] and we decided to delete this step without jeopardising ABT-263 supplier speed and reliability of the method. Three microlitre of ligation product was used

as template for RCA. The total volume was 46 μl containing 1 μl Bst DNA polymerase LF (New England Biolabs, Hitchin, UK), 1 μl deoxynucleoside triphosphate mix (5 mmol l−1), 1.5 μl of 10 pmol of RCA primer each, 5 μl RCA buffer 10×, 36 μl water. Probe signals were amplified by incubation at 65 °C for 60 min, and accumulation of double stranded DNA products was visualised on a 1% agarose gel to verify the specificity of probe-template binding. Positive reactions showed a ladder-like pattern, whereas negative reactions showed a clean background. Smart DNA ladder (0.2–10 kb; Eurogentec, Seraing, Belgium) was used as molecular weight standard. To evaluate the detection limit of the RCA assay, two microlitres of each 10-fold serial dilution find more was used in each RCA reaction. ITS amplicons of R. arrhizus var. delemar CBS 395.54 was used (Fig. 2). The ITS alignment revealed suitable positions for the development of padlock probes distinguishing between six taxa tested in this study. All tested strains generated positive results with respective padlock probes. The duration of the RCA assay was 2 h. Positive responses proved to be 100% specific for all strains, species-specific probes correctly identifying all six species and varieties analysed. No cross reaction was observed between these taxa (Fig. 1). CBS 395.54, CBS 109939, CBS 109940, CBS 103.

Thus the blockade in differentiation of maturing T and B

cells in the Snai3-expressing HSC occurs between the c-Kit+Sca− stage and the more mature common lymphoid progenitor population. The data presented in this report indicate that the expression of Snai3 in bone Proteases inhibitor marrow progenitors alters neither the maintenance of the stem cells nor the early stages of stem-cell differentiation but does dramatically skew the production of cells committed to the lymphoid or myeloid lineages. The Snai3 protein could alter these maturation profiles either through the repressor function of the SNAG domain of the protein, or by competing with endogenous transcriptional regulators for binding to E box sites. The identification of genes whose expression is influenced by the presence of Snai3 in these precursor populations may provide key insight into the regulation of differentiation of myeloid- and lymphoid-precursor cells. Animals were housed in the Animal Resource Center (University of Utah Health Science Center, Salt Lake City, UT) according to the guidelines of the National Institutes NVP-AUY922 datasheet of Health. C57BL/6 and B6.SJL-Ptprc Pepc/BoyJ were obtained from The Jackson Laboratories. C57BL/6CrSlc-Tg(ACTb-EGFP)OsbC14-Y01-FM131 mice ubiquitously expressing GFP were utilized [[27]]. The pBMN-1-GFP retrovirus was obtained from Addgene (plasmid 1736). The coding sequence of Snai3

(base pair (bp) 79–942 of NM_013914.2) was cloned into the Bam HI and XhoI sites of the vector. The Snai3 encoding cDNA was obtained by RT-PCR amplification of mouse thymus cDNA using 5′-CGGATCCATGCCGCGCTCCTTCCTGGTGA and 5′-GCTCGAGCTAGGGGCCAGGACAGCAGC oligonucleotides. PCR amplification was performed using Platinum pfx (Invitrogen, Grand Island, NY, USA). PCR amplification was 55°C annealing

Methane monooxygenase (30 s), 68°C extension (2 min) and 95°C denaturing (30 s) for 40 cycles. After subcloning the sequence was confirmed to match that of the reference sequence of NM_013914.2. Plat E cells were grown in stem cell media (SCM): Dulbecco’s modified Eagle’smedium (DMEM) supplemented with 15% FCS, P/S, 1 μg/mL puromycin (Sigma, St. Louis, MO, USA), and 10 μg/mL blasticidin (Sigma) except during virus production when antibiotics were subtracted [[28]]. Retroviral vectors were transfected into the Plat E packaging cell line using Fugene HD reagent (Roche, Pleasanton, CA, USA) at a 6:1 ratio. Cells were incubated at 37°C for 24 h then switched to 32°C for virus production in fresh media. Supernatant was collected and filtered through a 0.45 μm filter prior to use in transduction. B6.SJL were injected with 300 μL 10 mg/mL 5′fluorouracil (Sigma) in PBS [[29]]. Four days later their BM was collected and cultured with RBC in SCM with 100 ng/mL SCF (Sigma), 20 ng/mL IL-6 (Sigma), and 10 ng/mL IL-3 (Sigma) at 5–6 × 106 cell/mL for 2 days at 37°C. Stem cell cultures were collected and red blood cell (RBC) lysed with ammonium chloride potassium (ACK). Remaining cells were resuspended in 7.

1 Since then, the known biological function of complement in host defence PI3K Inhibitor Library manufacturer has greatly expanded. More recently, the relevance of complement to many human autoimmune and inflammatory disorders has

also become appreciated, and many efforts are currently underway to develop complement-based therapies for these diseases. Among the human diseases that have been linked to complement, several disorders of the kidney have been identified and extensively studied both clinically and experimentally. These works have not only provided insights into pathogenesis of the kidney abnormalities in question, but also contributed significantly to our understanding of complement-mediated human tissue injury in general. In this brief review, we summarize recent advances on the activation and regulation of the complement system in kidney disease, with a particular emphasis on the relevance of complement regulatory proteins. The complement system can be activated by three main pathways: classical, lectin and

alternative (Fig. 1).2,3 The classical pathway is triggered by antigen–antibody immune complexes.3 After binding to their cognate antigens, the Fc portion of an IgG or IgM interacts with the collagen-like tail of C1q, a component of C1 complex. This interaction leads to the sequential activation of C1r and C1s, two serine proteases associated with C1q within the C1 complex. The activated C1s then cleaves C4 and C2 to generate the classical pathway C3 convertase C4bC2a, an enzymatic complex that cleaves C3, the central component of the complement cascade, into C3a and C3b. The lectin pathway resembles Opaganib the classical pathway in that its activation also leads to formation of the C4bC2a enzyme complex. However, instead of relying on antibodies to recognize pathogenic

components, the lectin pathway identifies pathogen-associated molecular patterns by members of the collectin family of proteins in the plasma, namely mannose-binding lectins (MBL) and ficolins.2,3 Binding of MBL or ficolin to distinct sugar molecules on the pathogenic surface leads to activation of MBL-associated check serine proteases (MASP), which cleave C4 and C2 and generate C4bC2a in a reaction analogous to the classical pathway (Fig. 1).2 While the classical and lectin pathways are generally activated upon recognition of exogenous materials, the alternative pathway (AP) is constitutively active at low levels in the host.4 This is often referred to as the ‘tickover mechanism’ and allows the system to stay primed for rapid and robust activation.4 The AP is thought to be initiated by the spontaneous hydrolysis of a thioester bond within C3. This leads to a conformational change in the structure of C3, resulting in a form of C3, referred to as C3(H2O), which functions like C3b with regard to its ability to bind factor B (fB).

STAT1 can

exert its effect on target DNA either by direct binding or indirectly through the formation of complexes with other transcription factors. We hypothesized that the DNA-binding region of STAT1 may contain a site Selleck Ruxolitinib that is important for the constitutive interaction of STAT1 and the GILT promoter. Therefore, we tested whether known DNA-binding mutants – V426D/T427D,29 E428A/E429S30 and K544A/E545A,31– can alter the activity of the GILT promoter. Our luciferase reporter gene experiment indicated that only V426D/T427D was unable to decrease the activity of the GILT promoter, suggesting that STAT1 binding to DNA is necessary and that residues V426/T427 are the most important for the STAT1 suppressive effect on the ligand-independent activity of the GILT promoter. The mutant V426D/T427D is defective in the IFN-γ-induced STAT1 DNA binding buy PF-02341066 to specific GAS sites and shows weakened, non-specific protein–DNA interactions,29 and therefore the implication is that GAS sites remain an important target for STAT1, even in the absence of IFN-γ stimulation. The DAPA confirmed

that indeed the V426D/T427D (Mut 1) mutant cannot bind to GAS-like sites in the GILT promoter in vitro, whereas the K544A/E545A (Mut 3) mutant binds to GAS-like sites, albeit weakly. However, we were unable to show that the mutant E428A/E429S (Mut 2), which suppresses GILT promoter activity as in the WT, binds in vitro to a GAS-like site in the GILT promoter. This apparent discrepancy

may be caused by very weak binding to the GAS site in the GILT promoter that is below the limits of detection by DAPA, and/or perhaps is caused by the binding of this mutant to another, as yet unidentified, transcription factor. The fact that the absence of STAT1 increases the activity of the GILT promoter and GILT protein expression may be caused by competition/interaction of STAT1 with other transcription factors. For example, STAT3 can replace STAT1 in STAT1−/− cells to drive the transcription of certain genes in response oxyclozanide to IFN-γ or interleukin-6.41 STAT1 and STAT3 dimers bind selectively to very similar, but not identical, elements27,42 and thus activate different, but overlapping, sets of genes. In addition, Egr-1 (also designated zif268, TIS 8, NFGI-A, Krox 24) has been identified as one of the transcription factors that targets GILT.43 Egr-1 is a member of the immediate-early gene family that includes FOS, JUN and early growth-response genes.44,45 Egr-1 binds to 5′-GCGGGGGCG-3′ consensus sequences within the promoter region of target genes.46 The GILT promoter contains several GC-rich domains in the vicinity of GAS-like sites and it is therefore possible that the binding of Egr-1 and STAT1 to some regions of the GILT promoter are mutually exclusive. The competition for binding to the GILT promoter, if any, remains to be shown.

05 by the Mann–Whitney test). Furthermore, there was no significant difference between rE7-immunized mice and two other groups (P > 0.05). On the other hand, vaccination with the rE7-NT-gp96 protein

delayed tumour growth as compared to PBS and rE7 immunizations from 31 days after the TC-1 tumour challenge (Fig. 5A). Regarding to TC-1 tumour model, when the average tumour volumes in the PBS group had reached about 0.66 cm3 at 38th day after the TC-1 tumour challenge, it was only 0.01 and 0.13 cm3 in rE7-NT-gp96- and rE7-vaccinated mice, respectively. All mice immunized with rE7-NT-gp96 were tumour free, 35 days after TC-1 challenge (Fig. 5B). In contrast, 50% and 100% of the rE7- and PBS-immunized mice developed tumour at that time, respectively. Tumour-free percentage of the rE7-NT-gp96-immunized mice was significantly selleck compound higher than other groups (rE7-NT-gp96 versus rE7, P = 0.0174; ABT-888 manufacturer rE7-NT-gp96 versus PBS, P = 0.0048), whereas the difference between tumour-free

percentage of rE7- and PBS-injected mice was not significant at that time (P = 0.6948). This data indicated that rE7-NT-gp96 protein has the ability to postpone the tumour growth and can generate potent protective anti-tumour effects in comparison with other groups. Protein-based vaccines have emerged as an attractive approach for generating antigen-specific immune responses against various infectious diseases. The protein vaccination can elicit efficient antibody responses. PFKL Furthermore, they can overcome the human leucocyte antigen restriction of the peptide vaccines. However, owing to their low immunogenicity, there is still a need to increase protein-based vaccine potency. To enhance the immunogenicity of HPV protein-based vaccines, many efficient strategies have been applied such as different adjuvants (e.g. liposome-polycationic-DNA

adjuvant and saponin-based adjuvant ISCOMATRIX) and fusion of immunostimulatory proteins (e.g. heat shock proteins) [4, 30]. Many protein-based vaccines against HPV have been examined in clinical trials. For example, a HPV fusion protein composed of HPV-6 L2 and E7 (TA-GW), [31] and a fusion protein comprised of HPV-16 L2, E6 and E7 antigens [Tissue Antigen cervical intraepithelial neoplasia (TA-CIN)], [32] are among these types of trial vaccines. PD-E7, prepared from mutated HPV-16 E7 fused with a fragment of Haemophilus influenzae protein D formulated in an adjuvant system, was tested in another early clinical trials [33]. One more protein-based vaccine in clinical trial composed of HPV-16 E6/E7 fusion protein mixed with ISCOMATRIX adjuvant [34]. Heat shock proteins have been described as important immunostimulatory molecules to enhance antigen-specific tumour immunity. The antigenic properties of HSP can be exploited for increasing the humoral and cellular immune response to an attached protein.

The Fremantle Diabetes Study reported by Davis et al.,44 a longitudinal observational

study in a community based clinically-defined type 2 diabetes patient cohort, compared the ACR in self-identified Aboriginal and Torres Strait Islanders (n = 18) with Anglo Celt type 2 diabetes patients (n = 819), who represent the largest ethnic group within Silmitasertib clinical trial the patient community. The Aboriginal and Torres Strait Islander patients were significantly younger at diagnosis but had similar diabetes duration. Despite similar glycaemic management, the indigenous patients had higher HbA1c. The geometric mean ACR was significantly higher in Aboriginal compared with Anglo Celt patients (10.1 (1.1–93.6) vs 2.9 (0.7–12.4) mg/mmol, respectively). The SBP and DBP were lower and the smoking rate three times higher than in the Anglo Celt patients. Even though Aboriginal and Torres Strait Islander patients had a higher number of GP visits each year, they were less likely to have received diabetes education or to self monitor blood glucose. Overall there was no significant difference in the proportion of each group that died during the mean follow up period of 9.3 ± 3.2 years, however, the age at death was 18 years younger in the Aboriginal group. Aboriginal patients had a twofold higher risk of dying than Anglo Celts. Among other variables, urinary ACR was an independent predictor of all-cause A-769662 molecular weight mortality in Aboriginal and Torres Strait

Islander and Anglo Celt patients. The Fremantle Study, although the small number of indigenous patients reduces the ability to draw inferences about the urban indigenous population, suggests that sustained

high-level glycaemia and smoking are likely determinants of albuminuria in the Indigenous patients. Socio-economic status is associated with reduced access to primary medical care services and a lower level of utilization of those services and this is likely to be associated with poorer outcomes in relation to CKD in people with type 2 diabetes (Evidence Level IV). The mechanisms by which social disadvantage increases the risk of CKD have not been fully elucidated. However, social disadvantage appears to influence the stage of CKD at which specialist referral takes place, which in turn has negative implications Bupivacaine for individual outcomes. Access to and utilization of primary care medical services may also be lowest among those of highest social disadvantage and greatest need, thereby limiting the ability for implementation of interventions shown to prevent or reduce progression of CKD. Consideration of access to medical services needs to take into account both services related to prevention as well as specialist care for the management of CKD. Consistent with the study by Davis et al.,44 the socially disadvantaged are likely to be less educated in aspects of primary prevention and management. In relation to CKD, the timing of referral to a nephrologist might further influence the progression of CKD and overall outcomes.

Methods:  CA-4-P was given i.v. (25 mg/kg on alternate days for 14 days) to mice subjected to angiogenic stimuli (prazosin or synergist

extirpation). The responses of femoral artery blood flow as well as capillarity, capillary ultrastructure, and levels of Rho GTPase were measured. Results:  Blood flow was unaffected in the sprouting angiotype, but decreased https://www.selleckchem.com/products/icg-001.html in the splitting angiotype, by CA-4-P. In contrast, CA-4-P attenuated the capillarity increase in both models, associated with reduced lamellipodia and filopodia formation. Muscle overload, but not hyperemia, was accompanied by an increase in Rho GTPase with CA-4-P. Conclusions:  CA-4-P impaired the angiogenic response in both experimental models. This inhibitory effect was associated with a lower increase in femoral blood flow in splitting, whereas sprouting angiogenesis was accompanied by higher Rho activity consistent with the interruption of actin polymerization. Thus, CA-4-P may exert context-dependent anti-vascular and anti-angiogenic effects in vivo under physiological conditions. “

Spatial and Temporal Coordination of Bone Marrow-Derived Cell Activity during Arteriogenesis: Regulation of the Endogenous Response and Therapeutic Implications. Microcirculation17(8), 583–599. Arterial occlusive disease is the leading cause of morbidity

and mortality throughout the developed world, which creates a significant need for effective therapies to halt disease Protein Tyrosine Kinase inhibitor progression. Despite success of animal and small-scale human therapeutic arteriogenesis studies, this promising concept for treating SB-3CT arterial occlusive disease has yielded largely disappointing results in large-scale clinical trials. One reason for this lack of successful translation is that endogenous arteriogenesis is highly dependent on a poorly understood sequence of events and interactions between bone marrow derived cells (BMCs) and vascular cells, which makes designing effective therapies difficult. We contend that the process follows a complex, ordered sequence of events with multiple, specific BMC populations recruited at specific times and locations. Here, we present the evidence suggesting roles for multiple BMC populations—from neutrophils and mast cells to progenitor cells—and propose how and where these cell populations fit within the sequence of events during arteriogenesis. Disruptions in these various BMC populations can impair the arteriogenesis process in patterns that characterize specific patient populations. We propose that an improved understanding of how arteriogenesis functions as a system can reveal individual BMC populations and functions that can be targeted for overcoming particular impairments in collateral vessel development.

A total of 5831 men participated in this survey. Face-to-face interviews were used to collect data. Age, mobility, self-care ability, comorbidities and smoking were included as potential risk factors. The type of UI was assessed with the Urogenital Distress Inventory-6 questionnaire. To provide representative population prevalence estimates, the

sample population was weighted by age. Results: The age-adjusted prevalence of Korean male UI was 5.5%. Urgency urinary incontinence was the most prevalent incontinence type. Men aged 65 years and older had a rate of UI eight times that of men aged 19–44 years. Men with problems in mobility or self-care had an OR of 2.3 and 1.7, find more respectively. Conclusion: The age-adjusted prevalence of UI in community-dwelling Korean men was 5.5%, which is lower than that of Korean women and higher than previously reported prevalence of Korean male incontinence. Age, immobility, and self-care

“Objectives: Bladder outlet obstruction (BOO)-related detrusor hypertrophy is associated with upregulation of Rho-kinase (ROCK) activity in an experimental animal model, and has been implicated in BOO-induced bladder dysfunction. The aim of this study was to test whether chronic oral administration of an oral ROCK inhibitor, fasudil (HA1077, 5-isoquinolinesulfonyl homopiperazine), could prevent the development of both detrusor hypertrophy and detrusor overactivity in rat model. Methods: Thirty five-week-old male Sprague-Dawley rats ID-8 were divided into three groups (n SRT1720 = 10 per

group): control (sham surgical) with no treatment (group 1); 6-week obstructed rats (group 2); and 6-week obstructed rats treated for 6 weeks with fasudil (group 3). Results: The BOO group showed increased detrusor overactivity. Treatment with fasudil partly but significantly ameliorated the development of detrusor overactivity. The expression of RhoA protein in detrusor muscle was significantly greater in the BOO group than in the control group and subsequently decreased with fasudil treatment in the BOO-induced rat. Conclusion: These findings suggest that fasudil, a specific inhibitor of Rho-kinase, ameliorates BOO-induced detrusor overactivity in a rat model. Thus, ROCK inhibitor might be used as a novel agent to treat overactive bladder symptoms. “
“There is accumulated evidence that spontaneous contractions (SCs) in the bladder wall are associated with afferent nerve firing in the bladder. The role of the urothelium in bladder sensation might be restricted to pathological conditions, such as interstitial cystitis or chemical cystitis in which the release of urothelium-derived mediators such as adenosine triphosphate is increased.

The cytoplasmic expression strongly correlated with IL-1α expression (ρ = 0.9583). The cytoplasmic colocalization of HMGB1 and IL-1α was histologically confirmed in cells with collapsing nuclei by the double-staining method. The IgG4/IgG

indexes varied case by case. IL-6 and TLR4 expressions may influence IgG4/IgG index. The nuclei of cells with both IL-1α and HMGB1 expressions in the cytoplasm collapse in the cell death stage. The cooperative high expression of TLR4, IL-6, IL-18, MyD88 and HMGB1 suggest their learn more critical roles in the inflammation circuit. “

Beard (2011) Neuropathology and Applied Neurobiology37, 414–422 Intracisternal enzyme replacement therapy in lysosomal storage diseases: routes of absorption into brain Aims: The research concerns enzyme replacement therapy in lysosomal storage diseases with central nervous system involvement. The principle aim was to understand the routes of entry of enzyme into the brain when delivered directly into the cerebrospinal fluid (CSF) via the cerebellomedullary cistern. Methods: Pathways for absorption of replacement enzyme were investigated in dogs with mucopolysaccharidosis IIIA (MPSIIIA) following intracisternal Microbiology inhibitor injections of human recombinant N-sulphoglucosamine

sulphohydrolase (rhSGSH, EC3.10.1.1) by light and confocal microscopy using chromogenic and fluorescent immune probes. Results: Enzyme entered the brain superficially by penetration of the pia/glia limitans interface, but the main route was perivascular along large veins, arteries and arterioles extending onto capillaries. It further dispersed into surrounding neuropil to be taken up by neurones, macrophages, astrocytes and oligodendroglia. Enzyme also entered the lateral ventricles adjacent to the choroid plexus, probably also by the tela choroidea and medullary velum, with further spread throughout Clomifene the ventricular system

and spinal canal. There was secondary spread back across the ependyma into nervous tissue of brain and spinal cord. Conclusions: Enzyme mainly enters the brain by a perivascular route involving both arteries and veins with subsequent spread within the neuropil from where it is taken up by a proportion of neurones and other cells. Penetration of enzyme through the pia/glia limitans is minor and superficial. “
