  1. Up and down arrows indicate increase and decrease, respectively. FcγRs, Fcγ receptors; iNOS, inducible nitric oxide synthase; MHC, major histocompatibility complex; MIF, macrophage migration-inhibitory factor; NO, nitric oxide; PG, prostaglandin; ROI, reactive oxygen intermediates; TGF, transforming growth factor; TNF, tumour necrosis factor.
