The problem of Alzheimer's disease (AD) exemplifies the challenges of dealing with a broad range of aging-related chronic disorders that require long-term, labor-intensive, and expensive care. As the baby boom generation ages and brain diseases become more prevalent, the need to confront the pending health care crisis is more urgent than ever before.(More)
The monoclonal anti-idiotypic antibody (mAb2) 87.92.6 directed against the 9B.G5 antibody specific for the virus neutralizing epitope on the mammalian reovirus type 3 hemagglutinin was previously demonstrated to express an internal image of the receptor binding epitope of the reovirus type 3. Furthermore, this mAb2 has autoimmune reactivity to the cell(More)
In order to assess the importance of interleukin 2 receptor (IL-2R)-positive activated lymphocytes and macrophages in the pathogenesis of autoimmunity, we tested the prophylactic therapeutic efficacy of an anti-IL-2R (M7/20) monoclonal antibody, which recognizes the 55-kDa subunit of the heterodimeric IL-2R in two distinct models: the nonobese diabetic(More)
A cell-surface receptor for the mammalian reovirus type 3 hemagglutinin was isolated by using antiidiotypic anti-receptor antibodies. The receptor is a glycoprotein with a molecular mass of 67,000 daltons and a pI of 5.9. Evidence that the isolated structure represents the reovirus receptor was obtained by electrophoretic immunoblot studies, which(More)
A syngeneic monoclonal anti-idiotope that behaves as an internal image of the mammalian reovirus type 3 cellular attachment protein (viral hemagglutinin) was used in the syngeneic host for the induction of a prophylactic anti-viral antibody response. These studies were performed without the aid of co-stimulation by viral antigens. The high stringency of(More)
The addition of interleukin 2 (IL2) to the IL2-dependent murine cytotoxic T cell line CTTL-2 induced increased tyrosine phosphorylation of a protein with a molecular weight of 80,000 and, to a lesser extent, proteins with molecular weights of 130,000, 100,000, and 69,000. To correlate the stimulation of tyrosine phosphorylation with increased tyrosine(More)
CD34(+) cells are nonpermissive to infection by HIV strains X4 and R5, despite the fact that many CD34(+) cells express high levels of the viral receptor protein CD4 and the coreceptor CXCR4 on their surface. In these cells, the co-receptor CCR5 protein, which, like CXCR4, is a chemokine receptor, is detected mainly intracellularly. We hypothesized that(More)
A syngeneic monoclonal antiidiotypic antibody was generated in BALB/c mice after repeated immunization with a BALB/c monoclonal anti-reovirus hemagglutinin (HA) antibody. The resultant syngeneic monoclonal antiidiotypic antibody, in the absence of adjuvant, was found to be capable of priming both BALB/c (H-2d, Igh-1a) and C3H/Hej (H-2k, Igh-1j) mice for(More)
