immune system
abnormal NK cell physiology ( J:187430 )
• NK cells exhibit severely decreased killing of hematopoietic cells RMA-S, YAC-1 and MHC class I-deficient splenocytes in vitro compared with wild-type cells
• mice exhibit a 5-fold increase in residual RMA-S cells in the peritoneal cavity compared with wild-type mice
• when 2B4 is engaged, the activating effect is inhibited compared to on wild-type cells
• NK cells exhibit reduced conjugation with RMA-S cells compared with wild-type cells
• defects are not as severe as in Sh2d1atm1Pls homozygotes
• however, response to hamster CHO cells is normal

immune system
decreased IgE level ( J:93886 )
• after immunization with ovalbumin, severe deficit in IgE is observed with little or no Ig E detected; levels are slightly higher than in Sh2d1atm1Pls mice
abnormal CD4-positive, alpha-beta T cell physiology ( J:93886 )
• cells exhibit impaired IL-4 and IL-13 production upon stimulation with anti-CD3, anti-CD3 and anti-CD28 or PMA plus ionomycin
• naive CD4+ T cells have deficit in IL-4 production
abnormal memory T cell physiology ( J:93886 )
• function deficit of memory-type CD4+ T cells results in Th2 dysfunction (IL-4 production)
