Multifunctional extracellular vesicles inhibiting autophagy ameliorate immunotherapy in non-small cell lung cancer

mRNA. This process induces autophagy suppression and restores MHC-I expression, which synergizes with anti-PD-L1 immune checkpoint inhibition to enhance antitumor efficacy. In conclusion, this study proposes an innovative methodology that utilizes engineered sEVs for the co-delivery of protein antibodies and genetic materials. This approach establishes a promising strategy for advancing cancer immunotherapy by targeting the modulation of autophagy.
