A Protocol for the Comprehensive Flow Cytometric Analysis of Immune Cells in Normal and Inflamed Murine Non-Lymphoid Tissues.
(PloS one, 2016-01)Flow cytometry is used extensively to examine immune cells in non-lymphoid tissues. However, a method of flow cytometric analysis that is both comprehensive and widely applicable has not been described. We developed a protocol ... -
A Randomized Phase II Crossover Study of Imatinib or Rituximab for Cutaneous Sclerosis after Hematopoietic Cell Transplantation.
(Clin Cancer Res, 2016-01-15)PURPOSE: Cutaneous sclerosis occurs in 20% of patients with chronic graft-versus-host disease (GVHD) and can compromise mobility and quality of life. EXPERIMENTAL DESIGN: We conducted a prospective, multicenter, randomized, ... -
Adenovirus F protein as a delivery vehicle for botulinum B.
(BMC Immunol, 2010-07-07)BACKGROUND: Immunization with recombinant carboxyl-terminal domain of the heavy chain (Hc domain) of botulinum neurotoxin (BoNT) stimulates protective immunity against native BoNT challenge. Most studies developing a botulism ... -
An immunoglobulin C kappa-reactive single chain antibody fusion protein induces tolerance through receptor editing in a normal polyclonal immune system.
(J Exp Med, 2005-03-07)Understanding immune tolerance mechanisms is a major goal of immunology research, but mechanistic studies have generally required the use of mouse models carrying untargeted or targeted antigen receptor transgenes, which ... -
Analysis of Epstein-Barr virus-regulated host gene expression changes through primary B-cell outgrowth reveals delayed kinetics of latent membrane protein 1-mediated NF-κB activation.
(Journal of virology, 2012-10)Epstein-Barr virus (EBV) is an oncogenic human herpesvirus that dramatically reorganizes host gene expression to immortalize primary B cells. In this study, we analyzed EBV-regulated host gene expression changes following ... -
Analysis of memory B cell responses and isolation of novel monoclonal antibodies with neutralizing breadth from HIV-1-infected individuals.
(PLoS One, 2010-01-20)BACKGROUND: The isolation of human monoclonal antibodies (mAbs) that neutralize a broad spectrum of primary HIV-1 isolates and the characterization of the human neutralizing antibody B cell response to HIV-1 infection are ... -
B cells in rheumatoid synovitis.
(Arthritis Res Ther, 2005)In rheumatoid arthritis, T cells, B cells, macrophages, and dendritic cells invade the synovial membranes, establishing complex microstructures that promote inflammatory/tissue destructive lesions. B cell involvement has ... -
B-lymphocyte effector functions in health and disease.
(2010)B cells and humoral immunity make up an important component of the immune system and play a vital role in preventing and fighting off infection by various pathogens. B cells also have been implicated in the pathogenesis ... -
Costimulation blockade alters germinal center responses and prevents antibody-mediated rejection.
(Am J Transplant, 2014-01)De novo donor-specific antibody (DSA) after organ transplantation promotes antibody-mediated rejection (AMR) and causes late graft loss. Previously, we demonstrated that depletion using anti-CD3 immunotoxin combined with ... -
Cyclosporine A inhibits Ca2+-dependent stimulation of the Na+/H+ antiport in human T cells.
(J Cell Biol, 1986-08)The cyclic undecapeptide cyclosporine A (CsA) is a potent immunosuppressive agent that inhibits the initial activation of T lymphocytes. This agent appears to be most effective in blocking the action of mitogens such as ... -
Donor apoptotic cell-based therapy for effective inhibition of donor-specific memory T and B cells to promote long-term allograft survival in allosensitized recipients.
(American journal of transplantation : official journal of the American Society of Transplantation and the American Society of Transplant Surgeons, 2020-10)Allosensitization constitutes a major barrier in transplantation. Preexisting donor-reactive memory T and B cells and preformed donor-specific antibodies (DSAs) have all been implicated in accelerated allograft rejection ... -
Epstein-Barr virus induces global changes in cellular mRNA isoform usage that are important for the maintenance of latency.
(Journal of virology, 2013-11)Oncogenic viruses promote cell proliferation through the dramatic reorganization of host transcriptomes. In addition to regulating mRNA abundance, changes in mRNA isoform usage can have a profound impact on the protein output ... -
Genotypic analysis of B cell colonies by in situ hybridization. Stoichiometric expression of three VH families in adult C57BL/6 and BALB/c mice.
(J Exp Med, 1987-07-01)The filter paper disc method for cloning inducible lymphocytes was used to census the splenic B cell population of C57BL/6 and BALB/c mice for the expression of three VH gene-families, VH X-24, -Q52, and -J558. B cell colonies, ... -
Germinal center entry not selection of B cells is controlled by peptide-MHCII complex density.
(Nature communications, 2018-03-02)B cells expressing high affinity antigen receptors are advantaged in germinal centers (GC), perhaps by increased acquisition of antigen for presentation to follicular helper T cells and improved T-cell help. In this model ... -
Identification and utilization of arbitrary correlations in models of recombination signal sequences.
(Genome Biol, 2002)BACKGROUND: A significant challenge in bioinformatics is to develop methods for detecting and modeling patterns in variable DNA sequence sites, such as protein-binding sites in regulatory DNA. Current approaches sometimes ... -
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 ... -
Immune checkpoint modulation enhances HIV-1 antibody induction.
(Nature communications, 2020-02-19)Eliciting protective titers of HIV-1 broadly neutralizing antibodies (bnAbs) is a goal of HIV-1 vaccine development, but current vaccine strategies have yet to induce bnAbs in humans. Many bnAbs isolated from HIV-1-infected ... -
In situ studies of the primary immune response to (4-hydroxy-3-nitrophenyl)acetyl. I. The architecture and dynamics of responding cell populations.
(J Exp Med, 1991-05-01)After primary immunization with an immunogenic conjugate of (4-hydroxy-3-nitrophenyl)acetyl, two anatomically and phenotypically distinct populations of antibody-forming cells arise in the spleen. As early as 2 ... -
