Three subtypes of vesicular glutamate transporters, named VGLUT1-3, accumulate glutamate into synaptic vesicles. In this study, the post-natal expression of VGLUT3 was determined with specific probes and antiserums in the rat brain and compared with that of VGLUT1 and VGLUT2. The expression of VGLUT1 and VGLUT2 increases linearly during post-natal(More)
Adult skeletal muscles adapt their fiber size to workload. We show that serum response factor (Srf) is required for satellite cell-mediated hypertrophic muscle growth. Deletion of Srf from myofibers and not satellite cells blunts overload-induced hypertrophy, and impairs satellite cell proliferation and recruitment to pre-existing fibers. We reveal a gene(More)
The basal forebrain (BF) plays a role in behavioral and cortical arousal, attention, learning, and memory. It has been suggested that cholinergic BF neurons co-release glutamate, and some cholinergic BF neurons have been reported to contain vesicular glutamate transporter 3 (VGLUT3). We examined the distribution and projections of BF cholinergic neurons(More)
Gene transfer into pancreatic beta cells, which produce and secrete insulin, is a promising strategy to protect such cells against autoimmune destruction and also to generate beta cells in mass, thereby providing a novel therapeutic approach to treat diabetic patients. Until recently, exogenous DNA has been directly transferred into mature beta cells with(More)
Previous studies revealed that leukemia inhibitory factor (LIF) and retinoic acid (RA) induce a noradrenergic to cholinergic switch in cultured sympathetic neurons of superior cervical ganglia (SCG) by up-regulating the coordinate expression of choline acetyltransferase (ChAT) and the vesicular acetylcholine transporter. Here, we examined the effect of both(More)
A monoclonal antibody (mAb) designated 224-58 (IgM-kappa) has been raised by fusion of Sp2/0-Ag14 mouse hybridoma cell line with spleen cells of a mouse immunized with human brain myelin. This mAb binds specifically to mouse, rat, and human Schwann cells membrane. Serological tests showed that mAb 224-58 reacted with total lipid extract, but not with total(More)
Gammadelta T cells localize at mammalian epithelial surfaces to exert both protective and regulatory roles in response to infections. We have previously characterized the Mexican axolotl (Ambystoma mexicanum) T cell receptor delta (TRD) chain. In this study, TRD repertoires in spleen, liver, intestine and skin from larvae, pre-adult and adult axolotls were(More)
We have demonstrated by indirect immunofluorescence the cellular localization of a monoclonal antibody (mAb 224-58), produced after immunization of a mouse with human central nervous system (CNS) myelin. Serologically, mAb 224-58 was found to be specific for 3'-sulfomonogalactosylglycolipids, namely 3'-sulfogalactosylceramide (SGC) and 3'-sulfogalactosyl(More)
Skeletal muscle atrophy is a debilitating process that is associated with a wide variety of conditions including inactivity, disease and aging. Here, we demonstrate that the actin, myocardin-related transcription factors and serum response factor (actin-Mrtf-Srf) pathway is specifically downregulated in the muscle atrophy that is induced through disuse in(More)
