The immunodepressive effect of friend virus.

摘要: Friend virus was found to depress the primary haemagglutinin response sheep red blood cells in mice. The effect observed when injected at any time from 35 days 1 day before cells, but not later. Haemolysin production and proliferation of haemolysin-forming spleen were also depressed infected mice. When after a first second injection secondary depressed. The possible relation between these effects on immune reactivity cellular changes which produces are discussed. The another leukaemogenic (Moloney virus), non-oncogenic (the plasma lactate dehydrogenase elevating Riley), compared with that virus.
