摘要
在生殖中心(GC)B细胞衍生的淋巴瘤中,G蛋白Gα13经常丢失。缺乏 Gα13 的小鼠在肠道淋巴结中的 GC B 细胞增殖增加,进而发展成淋巴瘤。膳食谷氨酰胺能促进缺乏Gα13的粘膜GC B细胞的增殖,从而有可能解释这些淋巴瘤的肠道趋向性。
Dietary glutamine supports mucosal germinal center B cell lymphomas
The G protein Gα13 is frequently lost in germinal center (GC) B cell-derived lymphomas. Mice that lack Gα13 exhibit increased proliferation of GC B cells in gut-draining lymph nodes where they go on to develop lymphomas. Dietary glutamine drives the proliferation of mucosal GC B cells that lack Gα13, potentially explaining the gut tropism of these lymphomas.
期刊介绍:
Nature Immunology is a monthly journal that publishes the highest quality research in all areas of immunology. The editorial decisions are made by a team of full-time professional editors. The journal prioritizes work that provides translational and/or fundamental insight into the workings of the immune system. It covers a wide range of topics including innate immunity and inflammation, development, immune receptors, signaling and apoptosis, antigen presentation, gene regulation and recombination, cellular and systemic immunity, vaccines, immune tolerance, autoimmunity, tumor immunology, and microbial immunopathology. In addition to publishing significant original research, Nature Immunology also includes comments, News and Views, research highlights, matters arising from readers, and reviews of the literature. The journal serves as a major conduit of top-quality information for the immunology community.
