Immunization strategies that generate either CD4 or CD8 T cell responses are relatively well described, but less is known with regard to optimizing regimens to induce both CD4 and CD8 memory T cells. Considering the importance of both CD4 and CD8 T cells in the control of intracellular pathogens such as Leishmania donovani, we wanted to identify vaccines that could raise both CD4 and CD8 T cell...
The present study was undertaken to examine multifaceted therapeutic effects of vascular endothelial growth factor (VEGF) in a rat spinal cord injury (SCI) model, focusing on its capability to stimulate proliferation of endogenous glial progenitor cells. Neural stem cells (NSCs) can be genetically modified to efficiently transfer therapeutic genes to diseased CNS. We adopted an ex vivo approach...
Modulation of the sonic hedgehog (SHH) pathway is a crucial factor in cerebellar morphogenesis. Stimulation of granule neuron progenitor (GNP) proliferation is a central function of SHH signalling, but how this is controlled locally is not understood. We show that two sequentially expressed members of the contactin (CNTN) family of adhesion molecules, TAG1 and F3, act antagonistically to contro...
F3, a glycoprotein of the immunoglobulin superfamily implicated in axonal growth, occurs in oxytocin (OT)-secreting and vasopressin (AVP)-secreting neurons of the adult hypothalamo-neurohypophysial system (HNS) whose axons undergo morphological changes in response to stimulation. Immunocytochemistry and immunoblot analysis showed that during basal conditions of HNS secretion, there are higher l...
We had isolated a high molecular weight polysaccharide fraction, designated as F3, and performed a comprehensive analysis of its immunomodulatory and adjuvant activities in vivo and in vitro. In vivo, F3-treated mice showed an increase in the number of dendritic cells as well as CD4, CD8, regulatory T, B, plasma, NK, and NKT cells in the spleen. F3 also elevated the levels of multiple cytokines...
We have identified a zebrafish homolog of the F3/F11/contactin (F3) recognition molecule. The gene shares 55% amino acid identity with F3 molecules in other vertebrates. Expression of F3 mRNA is first detectable at 16 h post-fertilization (hpf) in trigeminal and Rohon-Beard neurons. At 18-24 hpf, additional weaker expression is present in discrete cell clusters in the hindbrain, in the anterior...
UNLABELLED There are almost no data concerning the involvement of endoplasmic reticulum stress (Ca2+ fluxes) in the apoptosis of the pro-B cell type Ba/F3. Thus, we aimed the characterization of thapsigargin-induced effects on Ba/F3 cells in vitro. MATERIAL AND METHOD For some experiments Ba/F3 cells were treated with 1 microM thapsigargin for 24 hours. To compare, we used as positive control...
