Abstract:

T cell exhaustion occurs mostly in chronic infections, cancers and autoimmune diseases. Continuous antigenic stimulation leads to the generation of exhausted T cells, which is characterized by progressive loss of effector function, continuous high expression of inhibitory receptors, transcription and epigenetic changes, and metabolic disorders. The in-depth study of the specific mechanism of T cell exhaustion is providing new ideas for the immunotherapy of chronic infection, lung cancer and chronic airway inflammatory disease in respiratory diseases. This paper discussed the influencing factors and characteristics of T cell exhaustion and reviewed the current research status of T cell exhaustion and respiratory diseases.

Key words: T cell exhaustion, inhibitory receptors, respiratory diseases, immunotherapy
