Fibroblast and T cells conditioned media induce maturation dendritic cell and promote T helper immune response
Dendritic cells (DCs) induce pathogen-specific T cell responses. We comprehensively studied the effects of addition of maturation stimulus, fibroblasts (fibroblast conditioned medium), PHA activated T cells (T cell conditioned medium), and mixture of fibroblast & PHA activated T cells (FCM-TCCM) conditioned media on maturation of DCs. Monocytes were cultured with GM-CSF and IL-4 for five days. ...
متن کاملPeptidoglycan from Staphylococcus aureus induces T(H)2 immune response in mice.
BACKGROUND AND OBJECTIVE Atopic dermatitis patients have an increased number of type 2 helper (T(H)2) cells in their peripheral blood and superficial Staphylococcus aureus colonization. The purpose of this study was to clarify the effects of peptidoglycan (PEG) from S aureus on the induction of the TH2 immune response in mice. METHODS Mice were primed with PEG- and ovalbumin (OVA)-pulsed Lang...
متن کاملCD81 on B cells promotes interleukin 4 secretion and antibody production during T helper type 2 immune responses.
Mice lacking CD81 (TAPA-1), a widely expressed tetraspanin molecule, have impaired antibody responses to protein antigens. This defect is specific to antigens that preferentially stimulate a T helper 2 response (ovalbumin or keyhole limpet hemocyanin in alum) and is only seen with T cell-dependent antigens. Absence of CD81 on B cells is sufficient to cause the defect. Also, antigen-specific int...
متن کاملT helper cell 1-type CD4+ T cells, but not B cells, mediate colitis in interleukin 10-deficient mice
Mice rendered deficient in the production of interleukin 10 (IL-10-/-) develop a chronic inflammatory bowel disease (IBD) that predominates in the colon and shares histopathological features with human IBD. Our aim was to identify which cell type(s) can mediate colitis in IL-10-/- mice. We detected an influx of immunoglobulin-positive cells into the colon and the presence of colon-reactive anti...
