Bone morphogenetic proteins (BMPs) induce autonomic neurogenesis in neural crest cultures and stimulate sympathetic neuron development when overexpressed in vivo. We demonstrate that inhibition of BMPs in the chick embryo bythe BMP antagonist Noggin prevents sympathetic neuron generation. In Noggin-treated embryos, the noradrenergic marker genes tyrosine(More)
Recombinant T-cell receptors with antibody-like specificity are successfully used to direct CTLs toward a MHC-independent immune response against target cells. Here we monitored the specific activation of receptor grafted CTLs in the context of CD28 costimulation. Peripheral blood T cells were retrovirally engrafted with recombinant anti-CD30 and(More)
Differentiation of noradrenergic neurons from neural crest-derived precursors results in the formation of primary sympathetic ganglia. As sympathetic neurons continue to divide after the acquisition of adrenergic and neuronal properties it was unclear, whether the increase in neuron number during neurogenesis is due to neuron proliferation rather than(More)
Arbuscular mycorrhizal fungi (AMF) are root-inhabiting fungi that form mutualistic symbioses with their host plants. AMF symbiosis improves nutrient uptake and buffers the plant against a diversity of stresses. Rhizophagus irregularis is one of the most widespread AMF species in the world, and its application in agricultural systems for yield improvement(More)
BACKGROUND Tetraspanins are transmembrane proteins known to contribute to angiogenesis. CD9 partner-1 (CD9P-1/EWI-F), a glycosylated type 1 transmembrane immunoglobulin, is a member of the tetraspanin web, but its role in angiogenesis remains to be elucidated. METHODS We measured the expression of CD9P-1 under angiogenic and angiostatic conditions, and(More)
