Open AccessMultiscale interactome analysis coupled with off-target drug predictions reveals drug repurposing candidates for human coronavirus disease
The COVID-19 pandemic has highlighted the urgent need for the identification of new antiviral drug therapies for a variety of diseases. COVID-19 is caused by infection with the human coronavirus SARS-CoV-2, wh...

Open AccessMultivalency transforms SARS-CoV-2 antibodies into ultrapotent neutralizers
SARS-CoV-2, the virus responsible for COVID-19, has caused a global pandemic. Antibodies can be powerful biotherapeutics to fight viral infections. Here, we use the human apoferritin protomer as a modular subu...

Open AccessA versatile soluble siglec scaffold for sensitive and quantitative detection of glycan ligands
Sialic acid-binding immunoglobulin-type lectins (Siglecs) are immunomodulatory receptors that are regulated by their glycan ligands. The connections between Siglecs and human disease motivate improved methods ...

Open AccessStructural characterization of the ICOS/ICOS-L immune complex reveals high molecular mimicry by therapeutic antibodies
The inducible co-stimulator (ICOS) is a member of the CD28/B7 superfamily, and delivers a positive co-stimulatory signal to activated T cells upon binding to its ligand (ICOS-L). Dysregulation of this pathway ...

Open AccessPotent antibody lineage against malaria transmission elicited by human vaccination with Pfs25
Transmission-blocking vaccines have the potential to be key contributors to malaria elimination. Such vaccines elicit antibodies that inhibit parasites during their development in Anopheles mosquitoes, thus break...

Open AccessMolecular recognition of the native HIV-1 MPER revealed by STED microscopy of single virions
Antibodies against the Membrane-Proximal External Region (MPER) of the Env gp41 subunit neutralize HIV-1 with exceptional breadth and potency. Due to the lack of knowledge on the MPER native structure and acce...

Open AccessStructural delineation of potent transmission-blocking epitope I on malaria antigen Pfs48/45
Interventions that can block the transmission of malaria-causing Plasmodium falciparum (Pf) between the human host and Anopheles vector have the potential to reduce the incidence of malaria. Pfs48/45 is a gametoc...

Article
Open AccessMolecular definition of multiple sites of antibody inhibition of malaria transmission-blocking vaccine antigen Pfs25
The Plasmodium falciparum Pfs25 protein (Pfs25) is a leading malaria transmission-blocking vaccine antigen. Pfs25 vaccination is intended to elicit antibodies that inhibit parasite development when ingested by An...

Article
Open AccessMolecular basis of human CD22 function and therapeutic targeting
CD22 maintains a baseline level of B-cell inhibition to keep humoral immunity in check. As a B-cell-restricted antigen, CD22 is targeted in therapies against dysregulated B cells that cause autoimmune diseases...

The structural basis of modified nucleosome recognition by 53BP1
A cryo-electron microscopy structure of the DNA damage repair protein 53BP1 bound to a nucleosome illuminates the way 53BP1 recognizes two types of histone modifications (a methyl group and a ubiquitin moiety)...

Article
Antibody potency relates to the ability to recognize the closed, pre-fusion form of HIV Env
HIV’s envelope glycoprotein (Env) is the sole target for neutralizing antibodies. The structures of many broadly neutralizing antibodies (bNAbs) in complex with truncated Env subunits or components have been r...

Structure of HIV-1 gp120 V1/V2 domain with broadly neutralizing antibody PG9
Variable regions 1 and 2 (V1/V2) of human immunodeficiency virus-1 (HIV-1) gp120 envelope glycoprotein are critical for viral evasion of antibody neutralization, and are themselves protected by extraordinary s...

Broad neutralization coverage of HIV by multiple highly potent antibodies
Broadly neutralizing antibodies against highly variable viral pathogens are much sought after to treat or protect against global circulating viruses. Here we probed the neutralizing antibody repertoires of fou...
