hematopoietic system
abnormal T cell morphology ( J:162065 )
• mice show the appearance of clonally-restricted, inactive yet functionally competent CD8 T cells, with an enrichment of CD8 T cells that lack glycosyl phosphatidylinositol (GPI) and GPI-anchored proteins in the blood, marrow, and spleen and enrichment of GPI- CD4 T cells in the spleen, and with pronounced Vbeta5.1/5.2 skewing of GPI- T cells
• however, mice do not show bone marrow failure, autoimmunity, or hemoglobinuria despite reduced immunosuppressive Treg cells
decreased CD4-positive, CD25-positive, alpha-beta regulatory T cell number ( J:162065 )
• the proportion of CD4+CD25+FoxP3+ regulatory T cells is lower in peripheral blood
• however, there are no differences in the proportion of natural killer T cells in peripheral blood
abnormal T cell physiology ( J:162065 )
• mice exhibit fewer GPI- gamma-interferon producing CD8 T and CD4 T cells after lectin stimulation with myristate acetate and ionomycin
abnormal T cell activation ( J:162065 )
• marker analysis indicates that the enlarged pool of GPI- CD8 T cells is less activated than normal T cells
