This study shows that B cells support tumor-specific CD4 T cells to enhance PD-1 blockade efficacy, but antibody secretion is not necessary for long-term survival.

This study identifies the role of mature dendritic cells type 1 in forming, maintaining, and functioning tertiary lymphoid structures in cancer.

This study shows ICOS limits the function of exhausted PD-1+ CD8 T cells by promoting their differentiation into less functional effector-like cells, and inhibiting ICOS improves anti-tumor responses.

This study shows that helpless CD8+ memory T cells, which form without CD4+ help, have transient functional impairments due to prolonged antigen exposure, which resolve over time.
