it is expressed constitutively at low levels on resting T, B, and myeloid-lineage cells and is strongly up-regulated by pro-inflammatory cytokines such as IFN-γ, TNF-α, IL-4, GM-CSF and by oncogenic signaling pathways (EGFR, ALK, KRAS, PI3K-AKT, STAT3, HIF-1α, NF-κB) in a wide spectrum of epithelial, hematopoietic, and mesenchymal tumors. Upon engagement with its cognate inhibitory receptor PD-1 (CD279) expressed on activated T, B, and NK cells, PD-L1 delivers a negative signal that recruits SHP-1\/2 phosphatases to the immunological synapse, thereby blocking PI3K-AKT and ZAP70 signaling, suppressing T-cell proliferation, cytokine production (IL-2, IFN-γ, TNF-α, granzyme B), and survival while promoting the induction and maintenance of peripheral tolerance, tissue-resident T-cell exhaustion, and Treg expansion. Clinically, PD-L1 protein expression—detected by FDA-approved 22C3, 28-8, SP142, or SP263 IHC assays—is a predictive biomarker for anti-PD-1\/PD-L1 checkpoint inhibitors used across more than 20 cancer types, with high membranous tumor and\/or immune cell staining (≥1–50 % cutoff depending on tumor type) correlating with improved objective response rates and progression-free survival; conversely, PD-L1 overexpression is itself an independent adverse prognostic factor in untreated solid tumors, reflecting immune evasion and aggressive biology.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e","brand":"Starter","offers":[{"title":"1mg","offer_id":43055933489227,"sku":"S0B7156-1mg","price":175.0,"currency_code":"USD","in_stock":true},{"title":"5mg","offer_id":43055933521995,"sku":"S0B7156-5mg","price":650.0,"currency_code":"USD","in_stock":true},{"title":"25mg","offer_id":43055933554763,"sku":"S0B7156-25mg","price":2170.0,"currency_code":"USD","in_stock":true},{"title":"50mg","offer_id":43055933587531,"sku":"S0B7156-50mg","price":3300.0,"currency_code":"USD","in_stock":true},{"title":"100mg","offer_id":43055933620299,"sku":"S0B7156-100mg","price":4670.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/36b18f2d54cb476d966b7503ba28dce6.jpg?v=1787281299","url":"https:\/\/www.antbioinc.com\/products\/invivo-anti-mouse-pd-l1-b7-h1-recombinant-mab-s0b7156","provider":"AntBio","version":"1.0","type":"link"}
