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)
Sympathetic neurons are specified during their development from neural crest precursors by a network of crossregulatory transcription factors, which includes Mash1, Phox2b, Hand2 and Phox2a. Here, we have studied the function of Gata2 and Gata3 zinc-finger transcription factors in autonomic neuron development. In the chick, Gata2 but not Gata3 is expressed(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)
Recombinant T-cell receptors with antibody-like specificity for tumor-associated antigens are successfully used to direct the cytolytic activity of T cells toward tumor cells. Clinical application, however, needs to comply with the low immunogenicity of the recombinant receptor, efficient gene transfer into peripheral blood T cells, and enrichment of(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)
Research provided evidence that personality traits influence the realization of implicit motives: Extraversion supported the successful realization of the implicit motives for affiliation and power, whereas introversion deflected implicit motives away from significant goals and created difficulties in goal attainment. Based on those findings on motive-trait(More)
In order to assess the alterations mediated by oxidative agents in physiological and pathological conditions, polyacrylamide gel electrophoresis was performed with dodecyl sodium sulphate of red cell membranes previously subjected to oxidative stress with malonyl dialdehyde generation. The alterations of the normal proteic profile observed were related to(More)
Arbuscular mycorrhizal fungi (AMF) are crucial components of fertile soils, able to provide several ecosystem services for crop production. Current economic, social and legislative contexts should drive the so-called "second green revolution" by better exploiting these beneficial microorganisms. Many challenges still need to be overcome to better understand(More)
