Viruses . 2025 Jan; 16(12). PMID: 39772242
Setting up a global SARS-CoV-2 surveillance system requires an understanding of how virus isolation and propagation practices, use of animal or human sera, and different neutralisation assay platforms influence assessment...

J Virol . 2023 Dec; 98(1):e0147823. PMID: 38085509
Consistent elicitation of serum antibody responses that neutralize diverse clades of HIV-1 remains a primary goal of HIV-1 vaccine research. Prior work has defined key features of soluble HIV-1 Envelope...

Front Immunol . 2023 Aug; 14:1231276. PMID: 37600825
The kinetics of Fc-mediated functions following SARS-CoV-2 infection or vaccination in people living with HIV (PLWH) are not known. We compared SARS-CoV-2 spike-specific Fc functions, binding, and neutralization in PLWH...

Mkhize N, Yssel A, Kaldine H, van Dorsten R, Woodward Davis A, Beaume N, et al.
PLoS Pathog . 2023 Jun; 19(6):e1011469. PMID: 37384759
The VRC01 Antibody Mediated Prevention (AMP) efficacy trials conducted between 2016 and 2020 showed for the first time that passively administered broadly neutralizing antibodies (bnAbs) could prevent HIV-1 acquisition against...

Bhiman J, Richardson S, Lambson B, Kgagudi P, Mzindle N, Kaldine H, et al.
Sci Rep . 2023 Jan; 13(1):1222. PMID: 36681693
The SARS-CoV-2 Omicron (B.1.1.529) Variant of Concern (VOC) and its sub-lineages (including BA.2, BA.4, BA.5, BA.2.12.1) contain spike mutations that confer high level resistance to neutralizing antibodies induced by vaccination...

Cell Rep Med . 2023 Jan; 4(1):100910. PMID: 36603577
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron BA.4 and BA.5 variants caused major waves of infections. Here, we assess the sensitivity of BA.4 to binding, neutralization, and antibody-dependent...

Sci Rep . 2022 Oct; 12(1):16473. PMID: 36182959
Antibodies with the same variable region can exist as multiple isotypes with varying neutralization potencies, though the mechanism for this is not fully defined. We previously isolated an HIV-directed IgA1...

PLoS Pathog . 2022 Sep; 18(9):e1010450. PMID: 36054228
Broadly neutralizing antibodies (bNAbs) that target the membrane-proximal external region (MPER) of HIV gp41 envelope, such as 4E10, VRC42.01 and PGZL1, can neutralize >80% of viruses. These three MPER-directed monoclonal...
