It is a protein expressed on antigen-presenting cells and some tumor cells helping them interact with T-cells. The molecular weight of PD-L1 is approximately 33 kDa. PD-L1 expression can occur in various tissues and is often upregulated in tumor microenvironments. This increased expression helps tumors evade the immune response.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nPD-L1 modulates the immune response by interacting with its receptor PD-1 on T-cells and other immune cells leading to immune suppression. It is part of the PD-1\/PD-L1 complex an important regulator of T-cell activity and immune tolerance. The binding of PD-L1 to PD-1 inhibits T-cell proliferation and cytokine production reducing the ability of the immune system to attack cancer cells.\u003cbr\u003e\nPathways\u003cbr\u003e\nPD-L1 is involved in the immune checkpoint pathway and the cancer immunity cycle. Its interaction with PD-1 influences important signaling cascades within these pathways affecting the immune system's capacity to target tumor cells effectively. Another protein important in this context is CTLA-4 another immune checkpoint regulator which along with PD-1 modulates immune system activity against cancer.\u003cbr\u003e\nPD-L1 has strong connections to cancer and autoimmune diseases. Many cancers including melanoma and non-small cell lung cancer exploit PD-L1 to protect themselves from the immune system. Increased PD-L1 expression can also impact autoimmune disorders where the immune system reacts against healthy body tissues. This interaction further involves PD-1 and CTLA-4 illustrating their shared roles in these disease contexts.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46844055748777,"sku":"ab228462","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab228462","provider":"Iright","version":"1.0","type":"link"}
