hematopoietic system

abnormal CD4-positive, alpha beta T cell morphology ( J:209872 )

• deletion of HA-specific Valpha8.3+CD4+CD8- thymocytes indicates deletion of autoreactive CD4+ T cells, although a subset of clonotypic CD4+ T cells evades deletion and accumulates in spleens and lymph nodes

• modest increase in the percentages of CD4+CD8- Foxp3+ thymocytes and of CD4+Foxp3+ splenocytes, however, the numbers of these cells that express the clonotypic TS1(SW) TCR are reduced, reflecting severe deletion of clonotype-expressing thymocytes

autoimmune arthritis ( J:209872 )
