|
• pro-T cells exhibit excessive cell death unlike wild-type cells
|
|
• 100-fold reduction in cellularity
|
|

• however, inhibition of SOCS1 or overexpression of Bcl2 restores T cell differentiation in vitro
|
|
• alphabeta-T cells are reduced 1000-fold compared to in wild-type mice
|
|
• early T-cell precursors in the thymus are reduced compared to in wild-type mice
|
|
