Function
PD-L1 plays a critical role in induction and maintenance of immune tolerance to self. As a ligand for the inhibitory receptor PDCD1/PD-1, modulates the activation threshold of T-cells and limits T-cell effector response. Through a yet unknown activating receptor, may costimulate T-cell subsets that predominantly produce interleukin-10 (IL10). Can also act as a transcription coactivator: in response to hypoxia, translocates into the nucleus via its interaction with phosphorylated STAT3 and promotes transcription of GSDMC, leading to pyroptosis; The PDCD1-mediated inhibitory pathway is exploited by tumors to attenuate anti-tumor immunity and escape destruction by the immune system, thereby facilitating tumor survival. The interaction with PDCD1/PD-1 inhibits cytotoxic T lymphocytes (CTLs) effector function. The blockage of the PDCD1-mediated pathway results in the reversal of the exhausted T-cell phenotype and the normalization of the anti-tumor response, providing a rationale for cancer immunotherapy[1][2][3][4][5][6][7].

Expression
Tissue_specificity:It is highly expressed in the heart, skeletal muscle, placenta, and lungs. It is weakly expressed in the thymus, spleen, kidneys, and liver. It is expressed on activated T cells and B cells, dendritic cells, keratinocytes, and monocytes; it is widely expressed, with the highest expression in the lungs, liver, pituitary gland, and various peripheral blood cells (including neutrophils and certain subtypes of lymphocytes and myeloid cells) .
Induction:Up-regulated on T- and B-cells, dendritic cells, keratinocytes and monocytes after LPS and IFNG activation. Up-regulated in B-cells activated by surface Ig cross-linking -
