Abstract
The first descriptions of "non-specific" killing of tumor cells by lymphocytes were reported in 1973, and subsequently, the mediators of the activity were named "natural killer" (NK) cells by Rolf Kiessling and colleagues at the Karolinska Institute in 1975. The activity was detected in mice, rats, and humans that had no prior exposure to the tumors, major histocompatibility complex (MHC) antigen matching of the effectors and tumor cells was not required, and the cells responsible were distinct from MHC-restricted, antigen-specific T cells. In the ensuing five decades, research by many labs has extended knowledge of NK cells beyond an in vitro curiosity to demonstrate their in vivo relevance in host defense against tumors and microbial pathogens and their role in regulation of the immune system. This brief Perspective highlights a timeline of a few selected advancements in NK cell biology from a personal perspective of being involved in this quest.
期刊介绍：
Since its establishment in 1896, the Journal of Experimental Medicine (JEM) has steadfastly pursued the publication of enduring and exceptional studies in medical biology. In an era where numerous publishing groups are introducing specialized journals, we recognize the importance of offering a distinguished platform for studies that seamlessly integrate various disciplines within the pathogenesis field.
Our unique editorial system, driven by a commitment to exceptional author service, involves two collaborative groups of editors: professional editors with robust scientific backgrounds and full-time practicing scientists. Each paper undergoes evaluation by at least one editor from both groups before external review. Weekly editorial meetings facilitate comprehensive discussions on papers, incorporating external referee comments, and ensure swift decisions without unnecessary demands for extensive revisions.
Encompassing human studies and diverse in vivo experimental models of human disease, our focus within medical biology spans genetics, inflammation, immunity, infectious disease, cancer, vascular biology, metabolic disorders, neuroscience, and stem cell biology. We eagerly welcome reports ranging from atomic-level analyses to clinical interventions that unveil new mechanistic insights.
