- Abstract
Despite no apparent defects in T cell priming and recruitment to tumors, a large subset of T cell rich tumors fail to respond to immune checkpoint blockade (ICB). We leveraged a neoadjuvant anti-PD-1 trial in patients with hepatocellular carcinoma (HCC), as well as additional samples collected from patients treated off-label, to explore correlates of response to ICB within T cell-rich tumors. We show that ICB response correlated with the clonal expansion of intratumoral CXCL13+CH25H+IL-21+PD-1+CD4+T helper cells (“CXCL13+TH”) and Granzyme K+PD-1+effector-like CD8+T cells, whereas terminally exhausted CD39hiTOXhiPD-1hiCD8+T cells dominated in nonresponders. CD4+and CD8+T cell clones that expanded post-treatment were found in pretreatment biopsies. Notably, PD-1+TCF-1+(Progenitor-exhausted) CD8+T cells shared clones mainly with effector-like cells in responders or terminally exhausted cells in nonresponders, suggesting that local CD8+T cell differentiation occurs upon ICB. We found that these Progenitor CD8+T cells interact with CXCL13+THwithin cellular triads around dendritic cells enriched in maturation and regulatory molecules, or “mregDC”. These results suggest that discrete intratumoral niches that include mregDC and CXCL13+THcontrol the differentiation of tumor-specific Progenitor exhasuted CD8+T cells following ICB.
