[Natural killers and interleukin-2 in mice of the strain MRL/MpJ-lpr/lpr]. / Estestvennye killery i interleikin-2 u myshei linii MRL/MpJ-1pr/1pr.

The functional activity of natural killers (NK) in the spleen and lymph nodes and interleukin-2 (IL-2) production have been studied in MPL-MpJ-lpr/lpr (H-2k) mice with genetically predetermined autoimmune diseases and CBA (H-2k) mice. In MPL/l mice it has been shown that NK activity in the spleen was markedly depressed already in the first month of life, whereas in lymph nodes there is a substantial NK activity on days 7-10, which reaches its maximum by the second month and by the 6th months is practically intractable. IL-2 production in MPL/l mice was depressed at all stages of investigation.
