PD-1 controls differentiation, survival, and TCR affinity evolution of stem-like CD8+ T cells.

Stem-like progenitors are a critical subset of cytotoxic T cells that self-renew and give rise to expanded populations of effector cells critical for successful checkpoint blockade immunotherapy. Emerging evidence suggests that the tumor-draining lymph nodes can support the continuous generation of these stem-like cells that replenish the tumor sites and act as a critical source of expanded effector populations, underlining the importance of understanding what factors promote and maintain activated T cells in the stem-like state. Using advanced 3D multiplex immunofluorescence imaging, here we identified antigen-presentation niches in tumor-draining lymph nodes that support the expansion, maintenance, and affinity evolution of a unique population of TCF-1+PD-1+SLAMF6 stem-like CD8+ T cells.

Extracellular vesicle-bound VEGF in oral squamous cell carcinoma and its role in resistance to Bevacizumab Therapy.

Background: Vascular endothelial growth factor (VEGF) is an important proangiogenic factor and has been considered as a key target of antiangiogenetic therapy in oral squamous cell carcinoma (OSCC). However, clinical application of bevacizumab, a specific VEGF antibody, didn't improve the survival rate of OSCC patients. One possible explanation is that VEGF gene expresses diverse isoforms, which associate with extracellular vesicles (EVs), and EVs potentially contribute to VEGF resistance to bevacizumab.
