Ghrelin is an acyl-peptide gastric hormone acting on the pituitary and hypothalamus to stimulate growth hormone (GH) release, adiposity, and appetite. Ghrelin endocrine activities are entirely dependent on its acylation and are mediated by GH secretagogue (GHS) receptor (GHSR)-1a, a G protein-coupled receptor mostly expressed in the pituitary and(More)
BACKGROUND Fas (CD95) triggers programmed cell death and is involved in shutting off the immune response. Inherited deleterious mutations hitting Fas or its signaling pathway cause autoimmune/lymphoproliferative syndrome (ALPS). OBJECTIVE To assess the possibility that decreased Fas function plays a role in development of MS. METHODS The authors(More)
Fas (CD95) is a transmembrane molecule that induces programmed cell death (PCD) of lymphocytes. We examined its function in children with chronic thrombocytopenia, serum autoantibodies, and lymphadenopathy and/or splenomegaly. We found that T-cell lines from six of seven patients with this autoimmune/lymphoproliferative disease (ALD) were relatively(More)
Fas (CD95) triggers programmed cell death and is involved in cell-mediated cytotoxicity and in shutting off the immune response. Inherited loss-of-function mutations hitting the Fas system cause the autoimmune/lymphoproliferative syndrome (ALPS). We have recently shown that ALPS patients' families display increased frequency of common autoimmune diseases,(More)
This work extends our previous finding that lymphocyte treatment with gp120IIIB specifically induces CD4 association with several surface molecules to other molecules and to three other gp120s from different HIV-1 strains. The ability to induce this association was displayed by the four gp120s employed, i.e. gp120IIIB, gp120SF2, gp120MN and gp120(451), and(More)
