Regulation of thymic epithelium by keratinocyte growth factor.
Here we demonstrate that keratinocyte growth factor (KGF) and FGFR2IIIb signaling can affect development and function of thymic epithelium (TE) and that alphabeta-lineage thymocytes contribute to intrathymic levels of KGF. Thymocyte expression of KGF is developmentally regulated, being undetectable in CD3-4-8- thymocytes and expressed at highest levels by mature CD4 or CD8 thymocytes. Exposure ...
متن کاملKeratinocyte growth factor (KGF) is required for postnatal thymic regeneration.
Keratinocyte growth factor (KGF) is a member of the fibroblast growth factor family that mediates epithelial cell proliferation and differentiation in a variety of tissues, including the thymus. We studied the role of KGF in T-cell development with KGF-/- mice and demonstrated that thymic cellularity and the distribution of thymocyte subsets among KGF-/-, wildtype (WT), and KGF+/- mice were sim...
متن کاملKeratinocyte growth factor preserves normal thymopoiesis and thymic microenvironment during experimental graft-versus-host disease.
Thymus-dependent reconstitution of the peripheral T-cell compartment is critical for the successful outcome of bone marrow transplantation. However, graft-versus-host disease (GVHD) affects thymic stromal function and thus prevents normal T-cell maturation and selection. To determine whether cytoprotection of thymic epithelial cells (TECs) by keratinocyte growth factor (KGF) averts GVHD-related...

results cloning was confirmed by pcr and restriction digestion. rt-pcr and sds-page represented expression of kgf in e. coli. the optimized expression was achieved 16 hours after induction with 0.3 mm iptg at 37°c in luria broth (lb) containing kanamycin. the 18 kda protein was confirmed by western blotting, using anti-his antibodies. conclusions the result of the present study indicated that e...
متن کاملKeratinocyte-derived T-cell growth factor: a T-cell growth factor functionally distinct from interleukin 2.
T-cell growth factor, more recently termed interleukin 2 (IL-2), is the product of activated T lymphocytes and is considered the principal trophic factor for T lymphocytes. The activity of IL-2 preparations is assessed by the degree to which they support the growth of various IL-2-dependent cell lines. We report that murine epidermal epithelial cells (keratinocytes) produce and release a factor...
