A Therapeutic Antibody for Cancer, Derived from Single Human B Cells.
(Cell Rep, 2016-05-17)Some patients with cancer never develop metastasis, and their host response might provide cues for innovative treatment strategies. We previously reported an association between autoantibodies against complement factor H ... -
Breadth of SARS-CoV-2 Neutralization and Protection Induced by a Nanoparticle Vaccine.
(bioRxiv, 2022-02-14)Coronavirus vaccines that are highly effective against SARS-CoV-2 variants are needed to control the current pandemic. We previously reported a receptor-binding domain (RBD) sortase A-conjugated ferritin nanoparticle (RBD-scNP) ... -
Co-evolution of a broadly neutralizing HIV-1 antibody and founder virus.
(Nature, 2013-04-25)Current human immunodeficiency virus-1 (HIV-1) vaccines elicit strain-specific neutralizing antibodies. However, cross-reactive neutralizing antibodies arise in approximately 20% of HIV-1-infected individuals, and details ... -
Common genetic variation and the control of HIV-1 in humans.
(PLoS Genet, 2009-12)To extend the understanding of host genetic determinants of HIV-1 control, we performed a genome-wide association study in a cohort of 2,554 infected Caucasian subjects. The study was powered to detect common genetic variants ... -
Computational analysis of antibody dynamics identifies recent HIV-1 infection.
(JCI insight, 2017-12-21)Accurate HIV-1 incidence estimation is critical to the success of HIV-1 prevention strategies. Current assays are limited by high false recent rates (FRRs) in certain populations and a short mean duration of recent infection ... -
Contributions of Mamu-A*01 status and TRIM5 allele expression, but not CCL3L copy number variation, to the control of SIVmac251 replication in Indian-origin rhesus monkeys.
(PLoS genetics, 2010)CCL3 is a ligand for the HIV-1 co-receptor CCR5. There have recently been conflicting reports in the literature concerning whether CCL3-like gene (CCL3L) copy number variation (CNV) is associated with resistance to HIV-1 ... -
Correction: Neutralization-guided design of HIV-1 envelope trimers with high affinity for the unmutated common ancestor of CH235 lineage CD4bs broadly neutralizing antibodies.
(PLoS pathogens, 2019-12-02)[This corrects the article DOI: 10.1371/journal.ppat.1008026.]. -
Development of mRNA manufacturing for vaccines and therapeutics: mRNA platform requirements and development of a scalable production process to support early phase clinical trials.
(Translational research : the journal of laboratory and clinical medicine, 2022-04)The remarkable success of SARS CoV-2 mRNA-based vaccines and the ensuing interest in mRNA vaccines and therapeutics have highlighted the need for a scalable clinical-enabling manufacturing process to produce such products, ... -
Differential inhibition of human immunodeficiency virus type 1 in peripheral blood mononuclear cells and TZM-bl cells by endotoxin-mediated chemokine and gamma interferon production.
(AIDS Res Hum Retroviruses, 2010-03)Bacterial lipopolysaccharide (endotoxin) is a frequent contaminant of biological specimens and is also known to be a potent inducer of beta-chemokines and other soluble factors that inhibit HIV-1 infection in vitro. Though ... -
Elevation of intact and proteolytic fragments of acute phase proteins constitutes the earliest systemic antiviral response in HIV-1 infection.
(PLoS pathogens, 2010)The earliest immune responses activated in acute human immunodeficiency virus type 1 infection (AHI) exert a critical influence on subsequent virus spread or containment. During this time frame, components of the innate ... -
Elucidation of hepatitis C virus transmission and early diversification by single genome sequencing.
(PLoS Pathog, 2012)A precise molecular identification of transmitted hepatitis C virus (HCV) genomes could illuminate key aspects of transmission biology, immunopathogenesis and natural history. We used single genome sequencing of 2,922 half ... -
Fab-dimerized glycan-reactive antibodies are a structural category of natural antibodies.
(Cell, 2021-05-18)Natural antibodies (Abs) can target host glycans on the surface of pathogens. We studied the evolution of glycan-reactive B cells of rhesus macaques and humans using glycosylated HIV-1 envelope (Env) as a model antigen. ... -
Functional Relevance of Improbable Antibody Mutations for HIV Broadly Neutralizing Antibody Development.
(Cell host & microbe, 2018-06)HIV-1 broadly neutralizing antibodies (bnAbs) require high levels of activation-induced cytidine deaminase (AID)-catalyzed somatic mutations for optimal neutralization potency. Probable mutations occur at sites of frequent ... -
H3N2 influenza infection elicits more cross-reactive and less clonally expanded anti-hemagglutinin antibodies than influenza vaccination.
(PloS one, 2011-01)During the recent H1N1 influenza pandemic, excess morbidity and mortality was seen in young but not older adults suggesting that prior infection with influenza strains may have protected older subjects. In contrast, a history ... -
HIV-1 Envelope Glycoproteins from Diverse Clades Differentiate Antibody Responses and Durability among Vaccinees.
(Journal of virology, 2018-04)Induction of broadly cross-reactive antiviral humoral responses with the capacity to target globally diverse circulating strains is a key goal for HIV-1 immunogen design. A major gap in the field is the identification of ... -
HIV-1 envelope gp41 broadly neutralizing antibodies: hurdles for vaccine development.
(PLoS Pathog, 2014-05) -
HLA class II-Restricted CD8+ T cells in HIV-1 Virus Controllers.
(Scientific reports, 2019-07-15)A paradigm shifting study demonstrated that induction of MHC class E and II-restricted CD8+ T cells was associated with the clearance of SIV infection in rhesus macaques. Another recent study highlighted the presence of ... -
Human Non-neutralizing HIV-1 Envelope Monoclonal Antibodies Limit the Number of Founder Viruses during SHIV Mucosal Infection in Rhesus Macaques.
(PLoS Pathog, 2015-08)HIV-1 mucosal transmission begins with virus or virus-infected cells moving through mucus across mucosal epithelium to infect CD4+ T cells. Although broadly neutralizing antibodies (bnAbs) are the type of HIV-1 antibodies ... -
Identification of autoantigens recognized by the 2F5 and 4E10 broadly neutralizing HIV-1 antibodies.
(J Exp Med, 2013-02-11)Many human monoclonal antibodies that neutralize multiple clades of HIV-1 are polyreactive and bind avidly to mammalian autoantigens. Indeed, the generation of neutralizing antibodies to the 2F5 and 4E10 epitopes of HIV-1 ... -
IDLV-HIV-1 Env vaccination in non-human primates induces affinity maturation of antigen-specific memory B cells.
(Communications biology, 2018-01)HIV continues to be a major global health issue. In spite of successful prevention interventions and treatment methods, the development of an HIV vaccine remains a major priority for the field and would be the optimal strategy ...
