Infiltration of hematogenous lineage cells into the central nervous system (CNS) was investigated in the twitcher mouse, a murine model of globoid cell leukodystrophy in human. The hematogenous cells were selectively labeled following intraperitoneal injection of rhodamine isothiocyanate (RhIc). The frequency of detecting Rhlc-labeled cells (Rhlc+ cells) in(More)
Permeability of brain capillaries of stroke-prone spontaneously hypertensive rats (SHRSP) was studied using labelling (horseradish peroxidase) and cytochemical techniques at the cellular level. In the cerebral capillary endothelium the tracer molecules were quickly transported by abundant transendothelial channels which directly connected the capillary(More)
We studied ultrastructurally cerebral perforating arteries in 60 stroke-prone spontaneously hypertensive rats (SHRSP), which were sequentially killed at 4-52 weeks of age before showing symptoms of stroke. Another 24 SHRSP were killed soon after they showed symptoms of cerebral infarction. The initial vascular lesions observed in the asymptomatic group(More)
Cerebral ischemia induces a massive efflux of glutamate causing delayed neuronal death in stroke-prone spontaneously hypertensive rats (SHRSP) but not in Wistar Kyoto rats (WKY). It is obvious that L-N-nitroarginine (L-NNA; NO synthase (NOS) inhibitor), benzamide (poly(ADP-ribose) synthetase inhibitor), and growth factors are involved in reducing neuronal(More)
BACKGROUND CpG oligodeoxynucleotides (ODNs), resembling bacterial DNA, are currently tested in clinical trials as vaccine adjuvants. They have the nuclease-resistant phosphorothioate bond; the immune responses elicited differ according to the CpG ODN sequence and vaccination method. To develop a CpG ODN that can induce plasmacytoid dendritic cell(More)
Effects of macrophage suppression on Schwann cell proliferation in Wallerian degeneration was investigated in vitro with thymidine autoradiography. Sciatic nerves of C57BL mice were transected shortly after an intraperitoneal injection of silica dust and Schwann cells were harvested at 1, 2, 3, 5, 7, and 10 days post-transection. In silica treated mice,(More)
The axolemma is considered a well-established mitogen, responsible for Schwann cell proliferation during Wallerian degeneration in the peripheral nerve. However, very little is known about the role of macrophages in Schwann cell proliferation. To test the possible influence of macrophages on Schwann cell proliferation during Wallerian degeneration,(More)
