Abstract
In recent years,immunotherapy has made remarkable progress in treating certain tumors and hematological malignancies.However,the efficacy of natural killer(NK)cells,which are an important subset of innate lymphocytes used in anticancer immunotherapy,remains limited.Hypoxia,a critical characteristic of the tumor microenvironment(TME),is involved in tumor development and resistance to radiotherapy,chemotherapy,and immunotherapy.Moreover,hypoxia contributes to the impairment of NK cell function and may be a significant factor that limits their therapeutic effects.Targeted hypoxia therapy has emerged as a promising research area for enhancing the efficacy of NK cell therapy.Therefore,understanding how the hypoxic TME influences NK cell function is crucial for improving antitumor treatment outcomes.
