'The ability to quantify and characterize antigen-specific CD8+ T cells irrespective of functional readouts using fluorochrome-conjugated peptide-major histocompatibility complex class I (pMHCI) tetramers in conjunction with flow cytometry has transformed our understanding of cellular immune responses over the past decade. In the case of prevalent CD8+ T cell populations that ... More
Cell type specific applicability of 5-ethynyl-2'-deoxyuridine (EdU) for dynamic proliferation assessment in flow cytometry.

Journal:Cytometry A
PubMed ID:19235202
'Using the nucleoside analogue EdU (5-ethynyl-2''-deoxyuridine) for thymidine substitution instead of BrdU (5-bromo-2''-deoxyuridine) in cell proliferation assays has recently been proposed. However, the effect of EdU on cell viability, DNA synthesis, and cell cycle progression and consequently its usability for dynamic cell proliferation analysis in vitro has not been explored. ... More
Immune attributes of cardiac-derived adherent proliferating (CAP) cells in cardiac therapy.

PubMed ID:22389069
'Cardiac-directed cell therapies show potential to reduce mortality and morbidity in heart disease. However, high functional efficacy should be complimented with low immunogenicity, in particular if allogeneic cell sources are applied. Therefore, we aimed to examine cardiac-derived adherent proliferating (CAP) cells with respect to their immunogenicity and immune modulatory features ... More
Regulatory B cell (B10 Cell) expansion during Listeria infection governs innate and cellular immune responses in mice.

Journal:J Immunol
PubMed ID:23275601
'Pathogens use numerous methods to subvert host immune responses, including the modulation of host IL-10 production by diverse cell types. However, the B cell sources of IL-10 and their overall influence on innate and cellular immune responses have not been well characterized during infections. Using Listeria as a model pathogen, ...

Amine reactive dyes: an effective tool to discriminate live and dead cells in polychromatic flow cytometry.
'Membrane-damaged cells caused by either mechanical trauma or through normal biological processes can produce artifacts in immunophenotyping analysis by flow cytometry. Dead cells can nonspecifically bind monoclonal antibody conjugates, potentially leading to erroneous conclusions, particularly when cell frequencies are low. To date, DNA intercalating dyes (Ethidium monoazaide (EMA), Propidium Iodide, ... More
