Subcutaneous Immunotherapy and Synbiotic Combination Shift T-Helper 1 and Cytotoxic T Cells in Allergic Rhinitis
Background: Synbiotics have been used in the prevention and treatment of various immunological diseases. We aimed to investigate the synergistic clinical and immunologic effects of synbiotics and subcutaneous allergen immunotherapy (SCIT) combination in patients with allergic rhinitis. Materials and Methods: Nineteen individuals with all...
متن کاملCytotoxic T cells in AIDS colonic cryptosporidiosis.
BACKGROUND/AIMS It is not known how enteric cryptosporidiosis induces severe intestinal impairment despite minimal invasion by the parasite. The aim of this study was to analyse the histological features and locally implicated immune cells in colonic biopsies of AIDS related cryptosporidiosis. PATIENTS/METHODS Colonic biopsies from patients with AIDS related cryptosporidiosis (n = 10, group I...
متن کاملCytotoxic T Cells and Cancer Therapy
The cytotoxic T lymphocyte (CTL, Tc) is a type of T lymphocyte/ white blood cell involved in the host’s cell-mediated immune response against cancerous cells, abnormal cells and cells infected with viruses. Signals from infected cells or cancer cells lead to the release of cytotoxins: perforin, granzymes, and granulysin by the TC cells. The activation of CTLs is mediated by the interaction of v...
متن کاملCytotoxic CD4 T Cells in Antiviral Immunity
CD4 T cells that acquire cytotoxic phenotype and function have been repeatedly identified in humans, mice, and other species in response to many diverse pathogens. Since CD4 cytotoxic T cells are able to recognize antigenic determinants unique from those recognized by the parallel CD8 cytotoxic T cells, they can potentially contribute additional immune surveillance and direct effector function ...
متن کاملWhy can't cytotoxic T cells handle HIV?
Conventional cytotoxic T lymphocytes (CTLs) that express the CD8 co-receptor alongside their clonally distributed receptor for antigen are superbly equipped to eliminate virus-infected cells. They recognize short peptide fragments of intracellular pathogens which are brought to the surface of the infected cell in the groove of the major histocompatibility complex (MHC)-encoded class I molecules...
