The Immunomodulatory Effect of Cyclophosphamide on Regulation of T-Cell Subsets and Antigen Presenting Cells.

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. ...

Engineered antigen-specific human regulatory T cells: immunosuppression of FVIII-specific T- and B-cell responses.

Expansion of human regulatory T cells (Tregs) for clinical applications offers great promise for the treatment of undesirable immune responses in autoimmunity, transplantation, allergy, and antidrug antibody responses, including inhibitor responses in hemophilia A patients. However, polyclonal Tregs are nonspecific and therefore could potentially cause global immunosuppression. To avoid this un...

Antigen-induced regulatory T cells.

Regulatory T cells participate in immunologic homeostasis by active suppression of inappropriate immune responses. Regulatory T lymphocytes expressing CD4 and CD25 antigens and naturally present in the peripheral blood were the first to be phenotypically characterized. However, their small number and antigen nonspecific suppression has prompted efforts to identify and dissect antigen-specific r...
