We studied the evolution of glycan-reactive B cells of rhesus macaques and humans using glycosylated HIV-1 envelope (Env) ...Natural antibodies (Abs) can target host glycans on the surface of pathogens. We studied the evolution of glycan-reactive B cells of rhesus macaques and humans using glycosylated HIV-1 envelope (Env) as a model antigen. 2G12 is a broadly neutralizing Ab (bnAb) that targets a conserved glycan patch on Env of geographically diverse HIV-1 strains using a unique heavy-chain (V) domain-swapped architecture that results in fragment antigen-binding (Fab) dimerization. Here, we describe HIV-1 Env Fab-dimerized glycan (FDG)-reactive bnAbs without V-swapped domains from simian-human immunodeficiency virus (SHIV)-infected macaques. FDG Abs also recognized cell-surface glycans on diverse pathogens, including yeast and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike. FDG precursors were expanded by glycan-bearing immunogens in macaques and were abundant in HIV-1-naive humans. Moreover, FDG precursors were predominately mutated IgMIgDCD27, thus suggesting that they originated from a pool of antigen-experienced IgM or marginal zone B cells. #1: Journal: bioRxiv / Year: 2020Title: Fab-dimerized glycan-reactive antibodies neutralize HIV and are prevalent in humans and rhesus macaques Authors: Acharya, P. / Williams, W. / Henderson, R. / Janowska, K. / Manne, K. / Parks, R. / Deyton, M. / Sprenz, J. / Stalls, V. / Kopp, M. / Mansouri, K. / Edwards, R.J. / Meyerhoff, R.R. / Oguin, ...Authors: Acharya, P. / Williams, W. / Henderson, R. / Janowska, K. / Manne, K. / Parks, R. / Deyton, M. / Sprenz, J. / Stalls, V. / Kopp, M. / Mansouri, K. / Edwards, R.J. / Meyerhoff, R.R. / Oguin, T. / Sempowski, G. / Saunders, K. / Haynes, B.F. | ||||||
