immune system
• thymocyte number is reduced by about half compared to controls
• 18% of lymph node T cells from female mice bearing H2-Db express the HY-alpha t cell receptor chain
• the majority of T cells in male mice are HYalpha+ CD4-CD8lo or HYalpha+ CD4-CD8-
• 5 of 29 thymocytes from H2-Db background mice not expressing the HY TCR show evidence of receptor editing though the small number of DP and SP thymocytes present suggests this process is inefficient
• thymocytes from male mice on a H2-Db background that express the HY receptor are CD69+ and undergoing apoptosis due to negative selection
• DN thymocytes of both sexes have premature expression of a T cell receptor (TCR)
• this TCR is specific for the male HY antigen and in many cases there is co-expression of CD25 and CD44
• the percentage of DN cells in the thymus is increased
• female mice on a H2-Db background have almost double the number of DP thymocytes compared to female mice carrying just the Tcrbeta transgene
• the majority of these DP thymocytes do not carry the HY TCR
• male mice on a H2-Db background have 4% the number of double positive thymocytes
• the percentage of DP thymocytes is decreased in these mice
