1 Hydroxychloroquine can impair tumor response to anti-PD1 in subcutaneous mouse models. Hydroxychloroquine programmed cell death 1 Mus musculus
2 Here, we evaluate the influence of HCQ treatment on the effect of anti-PD1 tumor immunotherapy. Hydroxychloroquine programmed cell death 1 Mus musculus
3 Anti-PD1 therapy-sensitive tumor lines MC38, CT26, and RIL-175 were used to investigate the impact of HCQ on anti-PD1 therapy efficacy. Hydroxychloroquine programmed cell death 1 Mus musculus
4 Importantly, in all the three tumor models, HCQ treatment significantly impaired the response to anti-PD1 treatment, accompanying diminished in vivo T-cell activation and reduced tumor-infiltrating, antigen-specific CD8+ T cells. Hydroxychloroquine programmed cell death 1 Mus musculus
