A model for harmonizing flow cytometry in clinical trials.
(Nat Immunol, 2010-11)Complexities in sample handling, instrument setup and data analysis are barriers to the effective use of flow cytometry to monitor immunological parameters in clinical trials. The novel use of a central laboratory may help ... -
A Novel Ex Vivo Method for Visualizing Live-Cell Calcium Response Behavior in Intact Human Tumors.
(PLoS One, 2016)The functional impact of intratumoral heterogeneity has been difficult to assess in the absence of a means to interrogate dynamic, live-cell biochemical events in the native tissue context of a human tumor. Conventional ... -
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) ... -
A Systematic Review of Conceptual Frameworks of Medical Complexity and New Model Development.
(J Gen Intern Med, 2016-03)BACKGROUND: Patient complexity is often operationalized by counting multiple chronic conditions (MCC) without considering contextual factors that can affect patient risk for adverse outcomes. OBJECTIVE: Our objective was ... -
A Vital Role for Interleukin-21 in the Control of a Chronic Viral Infection
(Science, 2009-06-19) -
Age patterns of incidence of geriatric disease in the U.S. elderly population: Medicare-based analysis.
(J Am Geriatr Soc, 2012-02)OBJECTIVES: To use the Medicare Files of Service Use (MFSU) to evaluate patterns in the incidence of aging-related diseases in the U.S. elderly population. DESIGN: Age-specific incidence rates of 19 aging-related diseases ... -
Age-specific differences in oncogenic pathway deregulation seen in human breast tumors.
(PLoS One, 2008-01-02)PURPOSE: To define the biology driving the aggressive nature of breast cancer arising in young women. EXPERIMENTAL DESIGN: Among 784 patients with early stage breast cancer, using prospectively-defined, age-specific cohorts ... -
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 ... -
An alphavirus vector overcomes the presence of neutralizing antibodies and elevated numbers of Tregs to induce immune responses in humans with advanced cancer.
(J Clin Invest, 2010-09)Therapeutic anticancer vaccines are designed to boost patients' immune responses to tumors. One approach is to use a viral vector to deliver antigen to in situ DCs, which then activate tumor-specific T cell and antibody ... -
An isolated working heart system for large animal models.
(J Vis Exp, 2014-06-11)Since its introduction in the late 19(th) century, the Langendorff isolated heart perfusion apparatus, and the subsequent development of the working heart model, have been invaluable tools for studying cardiovascular function ... -
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 ... -
Anti-AIDS agents 81. Design, synthesis, and structure-activity relationship study of betulinic acid and moronic acid derivatives as potent HIV maturation inhibitors.
(J Med Chem, 2010-04-22)In our continuing study of triterpene derivatives as potent anti-HIV agents, different C-3 conformationally restricted betulinic acid (BA, 1) derivatives were designed and synthesized in order to explore the conformational ... -
Anti-phospholipid human monoclonal antibodies inhibit CCR5-tropic HIV-1 and induce beta-chemokines.
(J Exp Med, 2010-04-12)Traditional antibody-mediated neutralization of HIV-1 infection is thought to result from the binding of antibodies to virions, thus preventing virus entry. However, antibodies that broadly neutralize HIV-1 are rare and ... -
Application of area scaling analysis to identify natural killer cell and monocyte involvement in the GranToxiLux antibody dependent cell-mediated cytotoxicity assay.
(Cytometry. Part A : the journal of the International Society for Analytical Cytology, 2018-04)Several different assay methodologies have been described for the evaluation of HIV or SIV-specific antibody-dependent cell-mediated cytotoxicity (ADCC). Commonly used assays measure ADCC by evaluating effector cell functions, ... -
Association between DNA Damage Response and Repair Genes and Risk of Invasive Serous Ovarian Cancer
(PLOS ONE, 2010-04-08) -
Association between DNA damage response and repair genes and risk of invasive serous ovarian cancer.
(PLoS One, 2010-04-08)BACKGROUND: We analyzed the association between 53 genes related to DNA repair and p53-mediated damage response and serous ovarian cancer risk using case-control data from the North Carolina Ovarian Cancer Study (NCOCS), ... -
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 ... -
B10 Cell Frequencies and Suppressive Capacity in Myasthenia Gravis Are Associated with Disease Severity.
(Front Neurol, 2017)Myasthenia gravis (MG) is a T cell-dependent, B cell-mediated disease. The mechanisms for loss of self-tolerance in this disease are not well understood, and recently described regulatory B cell (Breg) subsets have not been ... -
Breast cancer as heterogeneous disease: contributing factors and carcinogenesis mechanisms.
(Breast Cancer Res Treat, 2011-07)The observed bimodal patterns of breast cancer incidence in the U.S. suggested that breast cancer may be viewed as more than one biological entity. We studied the factors potentially contributing to this phenomenon, specifically ... -
