title: [Functional activity of T-, B-lymphocytes, and macrophages during suppression of expression of the env gene from an endogenous retrovirus genome].
abstract: Incubation of murine spleen cells with antisense oligonucleotide complementary to initiation site of this gene highly increased RNA synthesis relative to the normal T- and B-lymphocytes from spleen. In macrophages, inhibition of gene env expression stimulated phagocytosis and IL-1 production. Under these conditions, the level of expression of proviral envelope transmembrane p15E protein, which in infectious type C retroviruses is known to be immunosuppressive, decreased in spleen cells. Antisense oligonucleotide stimulatory effect on murine spleen cell RNA synthesis is presumably related to the reduced production of endogenous p15E.
