immune system
• thyroids are extensively infiltrated by T cells bearing transgenic TCR, B cells and some macrophages
• however, no symptoms of hypothyroidism occur
|
• the absolute number of double-positive T cells is reduced 3- to 4- fold
|
• 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 two-thirds
• 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
|
• in vitro TCR stimulation leads to greatly reduced expression of CD69 compared to T cells from mice transgenic for just the TCR
|
• CD4 T cells have a reduced proliferative response to hen egg lysozyme antigen compared to CD4 T cells from mice carrying just the TCR transgene
