immune system
increased T cell number ( J:201417 )
• uninduced mice exhibit an increase in tetramer+ T cells due to leaky cre expression
abnormal T cell physiology ( J:201417 )
• TCR-switched T cells treated with pIpC induce sterile inflammation in recipient mice possibly due to autoimmune activation
• however, recipient mice treated with galactosylceramide do not exhibit induction of NK T cell differentiation of TCR-switched tetramer+ T cells
