BCL2 and Autoimmunity: To further explore this problem, we study here the effects in the development of autoimmunity of the T-cell overexpression of BCL2A1 (also termed A1 or Bfl-1), another prosurvival member of the BCL2 family that together with MCL1 belongs to a different phylogenetic group than BCL2 and BCLXL [6, 14].
