Have Degree, Will Travel? Geography and Orthopaedic Surgery Residency Match.

Introduction: The paucity of objective data on the residency application is challenging to Orthopedic Surgery residency programs when selecting candidates to interview and to rank. Qualifying or quantifying the effect of geography on match results will help programs screen and rank candidates more effectively. The aim of this study is to describe the geographic background of current Orthopedic Surgery residents in the United States relative to their current residency program.

A multidonor class of highly glycan-dependent HIV-1 gp120-gp41 interface-targeting broadly neutralizing antibodies.

Antibodies that target the gp120-gp41 interface of the HIV-1 envelope (Env) trimer comprise a commonly elicited category of broadly neutralizing antibodies (bNAbs). Here, we isolate and characterize VRC44, a bNAb lineage with up to 52% neutralization breadth. The cryoelectron microscopy (cryo-EM) structure of antibody VRC44.

Application of B cell immortalization for the isolation of antibodies and B cell clones from vaccine and infection settings.

The isolation and characterization of neutralizing antibodies from infection and vaccine settings informs future vaccine design, and methodologies that streamline the isolation of antibodies and the generation of B cell clones are of great interest. Retroviral transduction to express Bcl-6 and Bcl-xL and transform primary B cells has been shown to promote long-term B cell survival and antibody secretion , and can be used to isolate antibodies from memory B cells. However, application of this methodology to B cell subsets from different tissues and B cells from chronically infected individuals has not been well characterized.

Longitudinal Analysis Reveals Early Development of Three MPER-Directed Neutralizing Antibody Lineages from an HIV-1-Infected Individual.

Lineage-based vaccine design is an attractive approach for eliciting broadly neutralizing antibodies (bNAbs) against HIV-1. However, most bNAb lineages studied to date have features indicative of unusual recombination and/or development. From an individual in the prospective RV217 cohort, we identified three lineages of bNAbs targeting the membrane-proximal external region (MPER) of the HIV-1 envelope.
