Structure and leukemogenic activity of a murine leukemia virus.

abstract：:NK cells are key effectors of innate immunity and host survival during cytomegalovirus (CMV) infection. Innate murine CMV (MCMV) resistance in MA/My mice requires Ly49H/m157-independent H-2k-linked NK cell control. Here we show that replacement of MA/My H-2k with C57L H-2b susceptibility genes led to a remarkable loss...

abstract：:The segment of simian virus 40 (SV40) genome which is recognized as the BC domain encodes for the COOH-terminal end of the SV40 major capsid protein VP1. Mutations in this domain lead to the synthesis of a thermosensitive VP1 which fails to assemble mature SV40 at the nonpermissive temperature. We determined the DNA s...
