The peptides of the present invention selected two peptides (PD-L1Pep-1 and PD-L1Pep-2) that bind well to cells with high expression of human PD-L1 protein using phage peptide display technology and it was confirmed that it inhibits its function by binding to PD-L1 in humans and mice. The peptide of the present invention showed an effect similar level to that of an antibody and is relatively stable in blood, indicating a high potential as a cancer immunotherapy in the future."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Peptide bound to PD-L1 and use thereof","description":"The present invention relates to a peptide bound to PD-L1 and uses for cancer immunotherapy and anticancer using the same, and the peptide of the present invention specifically binds to PD-L1 and inhi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11306119","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
