Major cells of the innate immune system includeneutrophils, which are first-line defenders against bacterial infection; dendritic cells (DCs), which serve to orchestrate immune responses; macrophages (Mφ’s), that perform important phagocytic, regulatory, andantigen presentationfunctions, and natural ...
In addition to killing, NK cells have another major function. These cells helpregulate the immune system response. They do so by secreting variouscell to cell communication signalscalled cytokines. Cytokines alert other cells of the immune system immunologic army to the fact that there are abnormal...
Tolerance to an individual's own antigens that is achieved through both central and peripheral tolerance mechanisms, including T cell deletion, anergy and immune regulation. Without central and peripheral tolerance, the immune system could not distinguish self from foreign antigens, resulting in autoimm...

functions of MSCs are well known; however, in all such known cases, MSCs execute its role by modulating functions of other cells, including T cells and macrophages43,44,45. Some of the key mediators that help MSCs execute these functions are PGE2, IDO1, IL6, CCL2, VEGFC, LIF etc.24,...
Immunosurveillance of cancer is well known. It is believed that escape from the immunosurveillance system and failure of the immunocytes to mount an adequate immune response lead to cancer. These and other evidences led to the development of immune check
major immune cell types in cancers including CD4+T, CD8+T, Treg, NK, monocyte, macrophages, neutrophil, B, plasma B, plasmacytoid dendritic cells (pDCs), and conventional DCs (cDCs). Compared with more than 80% of lymphoid cells in the control tumor, the percentage of T lymphocytes and ...
Currently unculturable, these anaerobes colonize the terminal ileum of rodents, adhering to ileal enterocytes, and they have a major impact on the development and composition of immune cell populations in the small intestine. Mucosal-associated invariant T cells (MAIT cells). Cells that express a ...
