Abstract

NK-22 cells: an anti-inflammatory role A previously unrecognized subset of human natural killer (NK) lymphocytes is reported. These 'NK-22' cells are selectively localized in tonsil and gut mucosa and, in contrast to conventional NK cells, are poorly cytotoxic and secrete little or no interferon. Rather, they specialize in the secretion of interleukin 22 (IL-22), IL-26 and leukaemia inhibitory factor, all of which have been implicated in the protection of epithelia. The properties of NK-22 cells are consistent with an anti-inflammatory response that may contribute to the maintenance of mucosal integrity.
