immune system
• there is a 32-fold reduction in the number of double positive T cells in the thymus
|
• there is reduced surface expression of T cell receptor components compared to mice transgenic for just the TCR transgene
• T cells also express surface markers indicative of recently being activated (high CD44, low CD45RB)
|
• CD 4 T cell numbers in the lymph nodes are reduced by almost three-quarters
• the number of lymph node CD4 T cells bearing a transgenic TCR is reduced 2- to 4- fold compared to mice transgenic just for the TCR
|
• CD4 T cells have a greatly reduced capability to activate and help B cell antibody production in vivo
|
• vitro TCR stimulation leads to greatly reduced expression of CD69 compared to T cells from mice transgenic for just the TCR
|
• CD4 T cells do not proliferate to hen egg lysozyme antigen compared to CD4 T cells from mice carrying just the TCR transgene
