Naturally Occurring Telomerase-Specific CD4 T-Cell Immunity in Melanoma.
CD4 T cells play a key role in anticancer immunity. In this study, we investigate the clinical relevance of circulating CD4 T helper type 1 (Th1) response against telomerase (anti-TERT Th1 response) in patients with melanoma. The spontaneous anti-TERT Th1 response was detected in 54.5% (85/156) of patients with melanoma before treatment. The prevalence of this systemic response was inversely related to Breslow thickness >1 mm and American Joint Committee on Cancer stage ≥II (P = 0.001 and 0.032, respectively). In contrast to patients treated with targeted therapies, the anti-TERT Th1 immunity was associated with an objective response after immune checkpoint inhibitors treatment. Hence, 86% …
Immunité spécifique anti-télomérase dans le mélanome
La reponse immunitaire lymphocytaire T CD4 Th1 joue un role important dans l’immunite anti tumorale et a ete etudiee dans de nombreux cancers. Nous avons evalue la reponse immunitaire T CD4 Th1 grâce a la reponse T CD4 Th1 anti-telomerase (anti-TERT) chez des patients atteints de melanome de tous stades AJCC. La reponse anti-TERT des lymphocytes de patients atteints de melanome etait evaluee par ELISpot IFN-γ et comparee aux donnees clinico-biologiques des patients. Au total, 171 patients atteints de melanome etaient inclus et 156 d’entre eux avaient une evaluation de la reponse anti-TERT disponible. Une reponse anti-TERT etait retrouvee chez 55 % des patients. La reponse anti-TERT etait mo…
