Des scientifiques chinois conçoivent un cocktail d’anticorps pour le traitement et la prévention

BEIJING, 2 mars (Xinhua) — Des scientifiques chinois ont conçu un cocktail d’anticorps pouvant donner un double coup au coronavirus responsable de la COVID-19. Les chercheurs de l’Université de médecine de la Capitale et de l’Académie des sciences de Chine ont mis au point l’anticorps monoclonal humain bispécifique contre le SRAS CoV-2, combinant une paire d’anticorps neutralisants humains non concurrents, à savoir B38 et H4, pour cibler deux antigènes, empêchant ainsi le virus de se lier à son récepteur.
