Repository- Live
Mice homozygous for the Jak3tm1Ljb mutation are viable and fertile. B cell development is blocked at pre-B resulting in a significant decrease in peripheral IgM+ B cells. The thymus is small but T cell development is relatively normal. There are increased numbers of CD4+ Cd8- cells in some homozygotes. Proliferative responses to mitogenic signals are defective and Il2 receptor signaling is blocked. The overall phenotype results in a severely immunocompromised mouse.
