Experiments were carried out to assess the role of naturally acquired antibody-specific immunoregulation in the immunodeficiency of aged individuals. It was found that greater than 50% of the primary dinitrophenyl-specific BALB/c B cells did not respond in carrier-primed 2-yr-old BALB/c adoptive hosts as compared with
RNAs of representative viruses of the exogenous simian sarcoma virus-gibbon ape lymphosarcoma virus (SiSV/GALV) and endogenous baboon virus (BaEV) classes of subhuman primate type C viruses were compared and related to HEL-12 virus, an isolate derived from human embryonic lung cells. The extent of sequence identity be

Closed circular viral DNA of simian sarcoma virus (SSV) and simian sarcoma-associated virus (SSAV) obtained from acutely infected dog cells was purified on preparative agarose gels, cleaved with EcoRI, and cloned in the phage lambda vector Charon 21A. The cloned 9-kilobase SSAV genome (B11) has the same restriction ma
