Description
Summary:The unique environment of the lungs is protected by complex immune interactions. Human lung tissue-resident memory T cells (T ) have been shown to position at the pathogen entry points and play an essential role in fighting against viral and bacterial pathogens at the frontline through direct mechanisms and also by orchestrating the adaptive immune system through crosstalk. Recent evidence suggests that T cells also play a vital part in slowing down carcinogenesis and preventing the spread of solid tumors. Less beneficially, lung T cells can promote pathologic inflammation, causing chronic airway inflammatory changes such as asthma and fibrosis. T cells from infiltrating recipient T cells may also mediate allograft immunopathology, hence lung damage in patients after lung transplantations. Several therapeutic strategies targeting T cells have been developed. This review will summarize recent advances in understanding the establishment and maintenance of T cells in the lung, describe their roles in different lung diseases, and discuss how the T cells may guide future immunotherapies targeting infectious diseases, cancers and pathologic immune responses.
