Natural Killer Cell Cytotoxicity Enhancement (None)

Target
None
Molecular classification
Immune process, Cellular process
01

Overview

Natural killer (NK) cell cytotoxicity enhancement refers to strategies and mechanisms aimed at increasing the ability of NK cells to recognize and destroy abnormal cells, such as tumor or virally infected cells. Key strategies include cytokine stimulation (IL-2, IL-15), monoclonal antibodies leveraging ADCC, bispecific engagers, modulation of intracellular signaling, and metabolic modulators. While promising for cancer immunotherapy, challenges include off-target toxicity and overcoming immunosuppressive signals within the tumor microenvironment.
