Conventional natural killer (cNK) cells patrol the organism via circulation and invade tissues in response to infection or inflammation. In this issue of Immunity, Torcellan et al. report that circulating cNK cells are recruited into infected skin and differentiate into long-lived tissue-resident NK cells capable of mediating an accelerated response upon reinfection.

关于血液和组织驻留的自然杀伤细胞

传统的自然杀伤 (cNK) 细胞通过循环在生物体中巡逻，并响应感染或炎症而侵入组织。在本期《免疫》中，托尔塞兰等人。报道称，循环的 cNK 细胞被招募到受感染的皮肤中，并分化为长寿命的组织驻留 NK 细胞，能够在再感染时介导加速反应。
