Structures of Respiratory Syncytial Virus G Bound to Broadly Reactive Antibodies Provide Insights into Vaccine Design

Respiratory syncytial virus (RSV) is one of the leading causes of severe lower respiratory infection in both infants and older adults. RSV viral entry and modulation of the host immunity is mediated by attachment glycoprotein RSV G binding to the chemokine receptor CX3CR1. Antibodies isolated from RSV-exposed individuals have shown great promise in host protection. Researchers using an ORIP-funded electron microscope, in conjunction with X-ray crystallography, have solved the structure of these antibodies bound to the RSV G protein and identified a novel dual antibody binding region. The presence of dual antibody binding sites indicates the potential to elicit antibody responses that resist virus escape. These findings will help develop next-generation RSV prophylactics and provide insight for new concepts in vaccine design. Supported by ORIP (S10OD027012, S10OD025097), NIAID, NHGRI, and NIGMS.

Systematic Ocular Phenotyping of 8,707 Knockout Mouse Lines Identifies Genes Associated With Abnormal Corneal Phenotypes

Vo et al., BMC Genomics. 2025.

Corneal dysmorphologies (CDs) are a group of acquired but predominantly genetically inherited eye disorders that cause progressive vision loss and can be associated with systemic abnormalities. This study aimed to identify candidate CD genes in humans by looking at knockout mice with targeted deletions of orthologous genes that exhibited statistically significant corneal abnormalities. Analysis of data from 8,707 knockout mouse lines identified 213 candidate CD genes; 176 (83%) genes have not been implicated previously in CD. Bioinformatic analyses implicated candidate genes in several signaling pathways (e.g., integrin signaling pathway, cytoskeletal regulation by Rho GTPase, FAS signaling pathway), which are potential therapeutic targets.
