The membrane-proximal external region (MPER) of the HIV-1 envelope is a target for broadly neutralizing antibodies (bnAbs), and vaccine-elicited MPER-directed antibodies have recently been reported from a human clinical trial. In this study, we sought to identify MPER-directed nAbs in simian immunodeficiency virus (SIV)-infected rhesus macaques. We isolated four lineages of SIV MPER-directed nAbs from two SIV-infected macaques.

Introduction: Rhesus macaques have long been a focus of research for understanding immune responses to human pathogens due to their close phylogenetic relationship with humans. As rhesus macaque antibody germlines show high degrees of polymorphism, the spectrum of database-covered genes expressed in individual macaques remains to be determined.
Methods: Here, four rhesus macaques infected with SHIV became a study of interest because they developed broadly neutralizing antibodies against HIV-1.
Identifying 10-year cumulative incidence and risk of revision following total hip arthroplasty in patients with and without a diagnosis of human immunodeficiency virus.

Department of Orthopaedic Surgery, Virginia Commonwealth University Health, Richmond, VA, USA.
Introduction: Prior studies have shown human immunodeficiency virus (HIV) may be a risk factor for early revision following THA, but little data exists looking at long-term implant survivorship. Therefore, the purpose of this study was to compare the 10-year cumulative incidence rate for revision following THA in patients with and without HIV.
Methods: A retrospective cohort analysis of patients with HIV undergoing elective THA was conducted using a national database.
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.
