    • The present invention pertains to novel modulators of resistance against T-cell mediated cytotoxic immune responses. The invention provides antagonists of immune escape mechanisms and therefore offers a novel approach for treating, or aiding a treatment, of various proliferative diseases such as cancerous diseases, in particular melanoma, pancreatic cancer and colorectal cancer. The invention specifically discloses the receptor Olfactory Receptor, Family 10, Subfamily H, Member 1 (OR10H1)as a checkpoint molecule in tumor resistance against cytotoxic T-cells. Provided is the inhibition of OR10H1 expression and/or function as a strategy for enhancing tumor susceptibility to a patients T-cell mediated immune response. Provided are antigen binding constructs for the detection of the OR10H1 protein, as well as inhibitory compounds, such as siRNA/shRNA molecules targeting OR10H1 and anti-OR10H1 antibodies, forimpairing the immune escape mediated by OR10H1. The invention furthermore provides screening methods for the identification of novel cancer therapeutics based on the modulation OR10H1 expression/function, diagnostic methods for the detection of immune resistance of a tumor to cytotoxic T-cell responses, as well as pharmaceutical compositions and diagnostic kits for performing these methods.
    • 本发明涉及抗T细胞介导的细胞毒性免疫应答的新型调节剂。 本发明提供了免疫逃避机制的拮抗剂,因此提供了治疗或帮助治疗各种增殖性疾病例如癌性疾病,特别是黑素瘤,胰腺癌和结直肠癌的新方法。 本发明特别公开了受体嗅觉受体家族10亚族H成员1(OR10H1)作为肿瘤抗细胞毒性T细胞的关卡分子。 提供了OR10H1表达和/或功能的抑制作为增强对患者T细胞介导的免疫应答的肿瘤易感性的策略。 提供了用于检测OR10H1蛋白的抗原结合构建体,以及抑制性化合物,例如靶向OR10H1和抗-OR10H1抗体的siRNA / shRNA分子,用于阻止OR10H1介导的免疫逃逸。 本发明还提供了用于鉴定基于调节OR10H1表达/功能的新型癌症治疗剂的筛选方法,用于检测肿瘤对细胞毒性T细胞应答的免疫抗性的诊断方法,以及用于进行表达的药物组合物和诊断试剂盒 这些方法。
