title: Transfusion-induced, Fc gamma-receptor-blocking antibodies: spectrum of cellular reactivity.
abstract: In this study we have shown that transfusion-induced Fc gamma R-blocking antibodies have the capacity to react with various cell types which are known to possess this receptor i.e., lymphocytes (T and B cells), polymorphs and platelets. In contrast we were unable to demonstrate any reactivity with K (or NK) lymphocytes or with monocytes. The spectrum of cellular reactivity exhibited by these antibodies suggests that their effect on the immune system may be complex.
