Most HIV-1-specific neutralizing antibodies isolated to date exhibit unusual characteristics that complicate their elicitation. Neutralizing antibodies that target the V1V2 apex of the HIV-1 envelope (Env) trimer feature unusually long protruding loops, which enable them to penetrate the HIV-1 glycan shield. As antibodies with loops of requisite length are created through uncommon recombination events,...
Previously, VLPs bearing JR-FL strain HIV-1 Envelope trimers elicited potent neutralizing antibodies (nAbs) in 2/8 rabbits (PLoS Pathog 11(5): e1004932) by taking advantage of a naturally absent glycan at position 197 that borders the CD4 binding site (CD4bs). In new immunizations, we attempted to improve nAb responses by removing the N362 glycan that also lines the CD4bs. All 4 rabbits developed...
Increasing evidence has demonstrated that men taking the anticoagulant warfarin have a lower risk of developing prostate cancer. This phenomenon is not observed in other cancers. We sought to determine if the target of warfarin, vitamin K epoxide reductase (VKOR), is expressed in benign and cancerous prostate tissues and if a functional single nucleotide polymorphism (SNP) in the VKOR gene is associated...
In the coming age of Internet of Things, the underlying infrastructure that supports IoT applications will play a pivotal role. Bluetooth Low Energy Beacons, small radio frequency broadcasters that advertise their unique identification, have been highlighted for their possible usage in the IoT infrastructure, as a sensor network of BLE Beacons is capable of providing contextual and locational information...
Virus-like particles (VLPs) offer a platform to test the hypothesis that, since antibody binding to native envelope glycoprotein (Env) trimers results in HIV-1 neutralization, that native Env trimers presented in membranes may be useful for inducing neutralizing antibodies (nAbs) in a vaccine setting. So far, VLPs have not fulfilled this potential. Here, using a “shotgun” approach, we evaluated a...
