immune system
• levels are dramatically reduced
|
• decreased killing of RMA-S, B16 and, to a lesser extent, YAC-1 cells
• reduced activating effect of 2B4 towards cytotoxicity
• reduced conjugation with RMA-S cells, less pronounced than in Sh2d1atm1Pls homozygotes
|
• pronounced defects in TCR-initiated proliferation and production of Ifng, IL-4 and IL-2 upon stimulation with anti-CD3 or anti-CD3 plus anti-CD28
• some responses are partially corrected by addition of exogenous IL-2, but IL-4 production block is not relieved
• cells exhibit impaired IL-4 and IL-13 production upon stimulation with anti-CD3, anti-CD3 and anti-CD28 or PMA plus ionomycin
|
• in response to RMA-S
