The role of costimulation and adjuvants in the development of T cell effector and memory responses

Creator:: Maxwell, Joseph R.
Abstract:: T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...

The effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin on T cell activation

Creator:: Shepherd, David M.
Abstract:: The immune system has been identified as a very sensitive target for the toxic effects of 2,3,7,S-tetrachlorodibenzo-p-dioxin (TCDD). Exposure to TCDD has been shown to disrupt the generation of both cell-mediated and humoral T cell-dependent immunity in laboratory animals; however, the mechanism remains unknown. In this dissertation, the hypothesis is...
