Intestinal fibroblastic reticular cells express key markers such as CCL19, CCL21, CXCL13, TNFSF13B (also known as BAFF), and produce IL-7, which are important for their immune regulatory functions and the organization of lymphoid structures. solitary intestinal lymphoid tissue fibroblastic reticular cell Ccl19-expressing fibroblastic reticular cell A specialized fibroblastic reticular cell that is part of gut-associated lymphoid tissue (GALT), responsible for forming a structural network that facilitates immune cell interactions. This cell is found in Peyer's patches, cryptopatches, and isolated lymphoid follicles. It plays crucial roles in maintaining intestinal immunity by controlling innate lymphoid cell homeostasis and function, organizing lymphoid structures, and contributing to intestinal microbiome balance. gut-associated secondary lymphoid organs fibroblastic reticular cell gut-associated lymphoid tissue
