hematopoietic system
increased gamma-delta T cell number ( J:110846 )
• null mice have ~2-fold increased numbers of gammadelta-TCR+ cells in the spleen and lymph nodes compared to controls
decreased lymphocyte cell number ( J:110846 )
• bone marrow cells from null mice transplanted into lethally-irradiated Rag1 mice show lower proliferation than wild-type BMC 2 months following transplantation
abnormal gamma-delta intraepithelial T cell morphology ( J:110846 )
• percentage of gammadelta-TCR+ intraepithelial cells are increased in the large intestine and decreased in the small intestine compared to controls
decreased CD8-positive, gamma-delta intraepithelial T cell number ( J:110846 )
• percentage of CDalphabeta8+ intraepithelial lymphocytes is reduced in the small intestine
