A pilot study of IL-2Rα blockade during lymphopenia depletes regulatory T-cells and correlates with enhanced immunity in patients with glioblastoma.
(PLoS One, 2012)BACKGROUND: Preclinical studies in mice have demonstrated that the prophylactic depletion of immunosuppressive regulatory T-cells (T(Regs)) through targeting the high affinity interleukin-2 (IL-2) receptor (IL-2Rα/CD25) ... -
Adjuvant Injections Altered the Ileal and Fecal Microbiota Differently with Changes in Immunoglobulin Isotypes and Antimycobacterial Antibody Responses.
(International journal of molecular sciences, 2023-02)Alterations in the gut microbiota, "dysbiosis," have been reported in autoimmune diseases, including multiple sclerosis (MS), and their animal models. Although the animal models were induced by injections of autoantigens ... -
Aggregate complexes of HIV-1 induced by multimeric antibodies.
(Retrovirology, 2014-10-02)BACKGROUND: Antibody mediated viral aggregation may impede viral transfer across mucosal surfaces by hindering viral movement in mucus, preventing transcytosis, or reducing inter-cellular penetration of epithelia thereby ... -
Allo-Specific Humoral Responses: New Methods for Screening Donor-Specific Antibody and Characterization of HLA-Specific Memory B Cells.
(Frontiers in immunology, 2021-01)Antibody-mediated allograft rejection (AMR) causes more kidney transplant failure than any other single cause. AMR is mediated by antibodies recognizing antigens expressed by the graft, and antibodies generated against major ... -
Alphavirus Replicon Particle Vaccine Breaks B Cell Tolerance and Rapidly Induces IgG to Murine Hematolymphoid Tumor Associated Antigens.
(Frontiers in immunology, 2022-01)De novo immune responses to myeloid and other blood-borne tumors are notably limited and ineffective, making our ability to promote immune responses with vaccines a major challenge. While focus has been largely on cytotoxic ... -
Association of HIV-1 Envelope-Specific Breast Milk IgA Responses with Reduced Risk of Postnatal Mother-to-Child Transmission of HIV-1.
(J Virol, 2015-10)UNLABELLED: Infants born to HIV-1-infected mothers in resource-limited areas where replacement feeding is unsafe and impractical are repeatedly exposed to HIV-1 throughout breastfeeding. Despite this, the majority of infants ... -
Beta-arrestin-2 regulates the development of allergic asthma.
(J Clin Invest, 2003-08)Asthma is a chronic inflammatory disorder of the airways that is coordinated by Th2 cells in both human asthmatics and animal models of allergic asthma. Migration of Th2 cells to the lung is key to their inflammatory function ... -
Characterization of CD4 and CD8 T cell responses in MuSK myasthenia gravis.
(J Autoimmun, 2014-08)Muscle specific tyrosine kinase myasthenia gravis (MuSK MG) is a form of autoimmune MG that predominantly affects women and has unique clinical features, including prominent bulbar weakness, muscle atrophy, and excellent ... -
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 ... -
Cross-Reactive Dengue Virus Antibodies Augment Zika Virus Infection of Human Placental Macrophages.
(Cell host & microbe, 2018-11)Zika virus (ZIKV), which emerged in regions endemic to dengue virus (DENV), is vertically transmitted and results in adverse pregnancy outcomes. Antibodies to DENV can cross-react with ZIKV, but whether these antibodies ... -
Cytotoxicity of alpha-particle-emitting astatine-211-labelled antibody in tumour spheroids: no effect of hyperthermia.
(Br J Cancer, 1998-03)The high linear energy transfer, alpha-particle-emitting radionuclide astatine-211 (211At) is of interest for certain therapeutic applications; however, because of the 55- to 70-microm path length of its alpha-particles, ... -
Differential chromatin accessibility in peripheral blood mononuclear cells underlies COVID-19 disease severity prior to seroconversion.
(Scientific reports, 2022-07-09)SARS-CoV-2 infection triggers profound and variable immune responses in human hosts. Chromatin remodeling has been observed in individuals severely ill or convalescing with COVID-19, but chromatin remodeling early in disease ... -
EAE cerebrospinal fluid augments in vitro phagocytosis and metabolism of CNS myelin by macrophages.
(J Neurosci Res, 1992-07)Previous studies from this laboratory have shown that CNS myelin is phagocytized and metabolized by cultured rat macrophages to a much larger extent when myelin is pretreated with serum containing antibodies to ... -
HIV-specific functional antibody responses in breast milk mirror those in plasma and are primarily mediated by IgG antibodies.
(J Virol, 2011-09)Despite months of mucosal virus exposure, the majority of breastfed infants born to HIV-infected mothers do not become infected, raising the possibility that immune factors in milk inhibit mucosal transmission of HIV. HIV ... -
HPV16 antibodies as risk factors for oropharyngeal cancer and their association with tumor HPV and smoking status.
(Oral Oncol, 2015-07)BACKGROUND: Antibodies (Abs) to the HPV16 proteome increase risk for HPV-associated OPC (HPVOPC). The goal of this study was to investigate the association of a panel of HPV16 Abs with risk for OPC as well as the association ... -
Immunodominant liver-specific expression suppresses transgene-directed immune responses in murine pompe disease.
(Hum Gene Ther, 2012-05)Pompe disease can be treated effectively, if immune tolerance to enzyme replacement therapy (ERT) with acid α-glucosidase (GAA) is present. An adeno-associated viral (AAV) vector carrying a liver-specific regulatory cassette ... -
Infectious virion capture by HIV-1 gp120-specific IgG from RV144 vaccinees.
(J Virol, 2013-07)The detailed examination of the antibody repertoire from RV144 provides a unique template for understanding potentially protective antibody functions. Some potential immune correlates of protection were untested in the correlates ... -
Lyme disease: authentic imitator or wishful imitation?
(JAMA Neurol, 2014-10) -
Maternal Fc-mediated non-neutralizing antibody responses correlate with protection against congenital human cytomegalovirus infection.
(The Journal of clinical investigation, 2022-08)Human cytomegalovirus (HCMV) is the most common congenital infection and a leading cause of stillbirth, neurodevelopmental impairment, and pediatric hearing loss worldwide. Development of a maternal vaccine or therapeutic ... -
