Viruses , including poxvirus , are known to possess efficient mechanisms allowing them to escape from the immune system of the infected host. One such mechanism is the possibility of inducing or suppressive effects of viruses on programmed cell death ( apoptosis ) . In this paper, the characteristics of the different ways of suppression of apoptosis by gene products of some chordopokswirusów ( orthopoxvirus , Leporipoxvirus and molluscipokswirusów ) . For proteins that are involved in the suppression of apoptosis by caspase inhibitors include poxvirus ?

Membrane prolactin receptor exhibit differences in both interspecies and intra. The occurrence of different variants of the receptor (isoforms) in the organs and tissues of the same individual can adjust the signal transmitted by the hormone. The article presents an overview of the various isoforms of the receptor expression in human and various animal species, and the latest data on the subsequent intracellular processes which occur upon binding of a ligand to a receptor activation step of specific genes.
