CD200 is a glycoprotein that is expressed on the surfaces of neurons and other cells. It interacts with its receptor, CD200R, which is expressed on cells of the myeloid lineage, including microglia. The interaction of CD200 with its receptor plays a significant role in maintaining microglia in a quiescent state; thus, a decrease in CD200 expression in the(More)
ETHNOPHARMACOLOGICAL RELEVANCE Myelophil, a combination of extracts taken from Astragali Radix and Salviae Miltiorrhizae Radix, is a traditional Chinese medicine used for the treatment of chronic fatigue-associated disorders. Here we examined the ability of Myelophil to alleviate memory impairment in a mouse model. We aimed to investigate whether Myelophil(More)
The maintenance of water homeostasis under pathological conditions is mediated by the aquaporin-4 (AQP4) channel in astrocytes. To clarify the transcriptional regulation for AQP4 under conditions of astrocytic swelling, we examined the role of nuclear factor of activated T cells 5 (NFAT5). We evaluated NFAT5 expression patterns after the induction of brain(More)
Growth differentiation factor 15 (GDF15) is, a member of the transforming growth factor β (TGF-β) superfamily of proteins. Although GDF15 is well established as a potent neurotrophic factor for neurons, little is known about its role in glial cells under neuropathological conditions. We monitored GDF15 expression in astrocyte activation after a kainic acid(More)
This study confirms that botulinum neurotoxin type A (BoNT-A) decreases capsular contracture and elucidates a possible mechanism. Silicone blocks were implanted subcutaneously in 20 mice. The experimental groups received BoNT-A (1, 2·5 or 5 U) instilled into the subcutaneous pocket. After 30 days, periprosthetic capsules were harvested and evaluated. The(More)
UV-mutagenesis was performed to obtain mutant strains that demonstrate altered production of phleichrome, a secondary metabolite of Cladosporium phlei. Among fifty mutants selected, based on the increased area and intensity of the purple pigment surrounding the colonies, the strain M0035 showed the highest production of phleichrome, more than seven fold(More)
3-phosphoinositide-dependent kinase-1 (PDK1) is suggested to play important roles in the regulation of synaptic plasticity and neuronal cell survival in the mature CNS. Although few studies have investigated the roles of PDK1, little is known about PDK1 changes in glial cells under neuropathological conditions. In current report, phosphorylation of PDK1 was(More)
Impaired spinal GABAergic inhibitory function is known to be pivotal in neuropathic pain (NPP). At present, data concerning time-dependent alterations in cell type and cell death in the spinal dorsal horn are highly controversial, likely related to the experimental NPP model used. In this study, we examined the expression of autophagy using a L5 spinal(More)
Repeated seizures induce permanent alterations in the hippocampal circuits in experimental models with intractable temporal lobe epilepsy. Sprouting and synaptic reorganization induced by seizures has been well-studied in the mossy fiber pathway. However, studies investigating sprouting and synaptic reorganization beyond the mossy fiber pathway are limited.(More)
The Rho GDP-dissociation inhibitor (RhoGDI) originally downregulates Rho family GTPases by preventing nucleotide exchange and membrane association. Although RhoGDI2 functions as a metastasis regulator, little is known in glial cells under neuropathological conditions. We monitored RhoGDI2 expression in the mouse brain after administering a kainic(More)
