Fas/FasL in the immune pathogenesis of severe aplastic anemia
Fas/FasL protein expression of bone marrow hematopoietic cells was investigated in severe aplastic anemia (SAA) patients. Fas expression was evaluated in CD34+, GlycoA+, CD33+, and CD14+ cells labeled with monoclonal antibodies in newly diagnosed and remission SAA patients along with normal controls. FasL expression was evaluated in CD8+ cells in the same manner.
