we propose that the newly recognized fcr that binds aggmigg2b is the human homologue of the murine macrophage igg2b/1 fcr ( fcrii ) , and that the previously described 72,000 dalton high-affinity fcr on u937 cells that binds migg2a is the human equivalent of the murine macrophage igg2a fcr ( fcri ) .
