Abstract B084: Tracking tumor-specific CD4 T cells in pancreatic cancer reveals an essential role for cognate interactions with myeloid cells in remodeling the tumor microenvironment following immunotherapy
Our study identified an antigen (Ag)-specific CD4 T cell population in a preclinical orthotopic model of pancreatic ductal adenocarcinoma (PDA) that, upon expansion, elicited robust antitumor control. We developed an affinity-enhanced MHC-II tetramer to follow the endogenous tumor-specific CD4 T cells during pancreat...
