mp3>>DOWNLOADMacrophage-dendritic cell (DC) interactions play a key role in the generation of immune responses. DCs are able to take up and process antigens, and stimulate antigen-specific T cells by processing antigen and presenting it to T cells via MHC class II or MHC class I and CD8. It has been shown that B cells and macrophages also are able to take up and process antigens to present to T cells via MHC class I, but the extent to which macrophages have this capacity is not known. The other major cell type capable of antigen presentation to T cells via MHC class I is the dendritic cell (DC). It is unknown whether macrophages can also present antigen to T cells via MHC class I. We have shown that, as with other antigen-presenting cells, a role for macrophages in antigen presentation to T cells is possible, and that this occurs in a non-classical MHC class I-dependent manner. The studies in this proposal are designed to study the capacity of human macrophages to present antigen to T cells. Specifically, we will (1) determine if T cells require direct interactions with macrophages to develop into effectors in response to antigens processed by macrophages; (2) evaluate the ability of macrophages to process antigens to present to CD8+ and CD4+ T cells; (3) determine if macrophages require MHC class II to present antigen to T cells in a non-classical, MHC-independent fashion. The information gained from these studies will allow us to determine whether macrophages can present antigen via MHC class I or MHC class II, and if so, whether macrophages can present antigen via a novel, non-classical MHC class I-dependent manner. These studies will not only improve our understanding of antigen presentation in the setting of infectious diseases, but will also provide insights into a previously unrecognized form of antigen presentation by non-classical antigen-presenting cells.Q: How to detect that my proxy server is working on MAC OS? i'm testing on my mac if the proxy server is working or not? i'm using this: import os print("" +os.environ['http_proxy']+"/") And on my PC with import
