The immunogenic Heat shock proteins (HSPs) gp96, hsp70 and calreticulin bind to CD91 on antigen presenting cells for cross-presentation of the HSP-chaperoned peptides. This event leads to priming of T cell responses. We show that CD91 serves as a signaling receptor for these HSPs allowing for the maturation of the antigen presenting cells (APC), secretion of cytokines, and priming of T helper cells. Specifically, CD91 is phosphorylated in response to HSPs in a unique pattern and phospho-CD91 triggers signaling cascades to activate NF-κB. Each HSP-CD91 interaction on antigen presenting cells stimulates a unique cytokine profile which dictates priming of specific T helper cell subsets. Thus, in a TGF-β tumor microenvironment, immunization with calreticulin but not gp96 or hsp70 primes Th17 cell responses in a CD91-dependent manner. These results are important for development of T cell responses in situ in tumor-bearing hosts and for vaccination against cancer and infectious disease.
