Abstract

La présente divulgation concerne des anticorps et des fragments de liaison à l'antigène de ceux-ci qui peuvent se lier à un antigène du SARS-CoV-2 et, dans certains modes de réalisation, peuvent neutraliser une infection par le SARS-CoV-2. Dans certains modes de réalisation, les anticorps présentement décrits peuvent se lier à des protéines S de multiples sarbécovirus et/ou neutraliser une infection par de multiples sarbécovirus. Dans certains modes de réalisation, un sarbecovirus est issu de la clade 1a, de la clade 1b, de la clade 2 ou de la clade 3. Dans certains modes de réalisation, un sarbecovirus comprend un SARS-CoV-2, un variant G504D du SARS-CoV-2, un variant delta du SARS-CoV, un SARS-CoV, ou toute combinaison de ceux-ci. L'invention concerne également des polynucléotides qui codent pour un anticorps ou un fragment de liaison à l'antigène, des vecteurs et des cellules hôtes qui comprennent un polynucléotide, des compositions pharmaceutiques, ainsi que des méthodes d'utilisation des anticorps, des fragments de liaison à l'antigène, des polynucléotides, des vecteurs, des cellules hôtes et des compositions présentement décrits pour traiter ou diagnostiquer une infection à sarbécovirus, telle qu'une infection par le SARS-CoV-2.
