They are part of the high affinity IgE receptor in mast cells , basophils , Langerhans cells , and possibly other cells ; a component of the low affinity receptor for IgG ( Fc gamma RIIIA or CD16 ) in natural killer cells and macrophages ; and part of the T cell antigen receptor in subsets of T cells .
