Identification of economically important parasites.

abstract：:Humoral immune responses to immunization and infection and susceptibilities to antibody-mediated autoimmunity are generally lower in males1-3. However, the mechanisms underlying such sexual dimorphism are not well understood. Here we show that there are intrinsic differences between the B cells that produce germinal c...

abstract：:Rous sarcoma virus (RSV) is an acutely oncogenic avian retrovirus which induces sarcomas in animals and transforms fibroblasts in cell culture. Genetic analysis indicates that the viral src gene (v-src) mediates neoplastic transformation. The product of v-src is a 60,000 molecular weight (MW) phosphoprotein (pp60v-src...
