Human keratinocyte growth factor (KGF) is a recently identified mitogen for epithelial cells produced by normal stromal fibroblasts. KGF has been shown to stimulate keratinocyte migration and promote re-epithelialization of skin suggesting a critical role for KGF in wound healing. To understand how KGF might be regulated during wound healing, we examined the ability of the pro-inflammatory cyto...
RATIONALE Rhinoviruses are the major cause of asthma exacerbations; however, its underlying mechanisms are poorly understood. We hypothesized that the epithelial cell-derived cytokine IL-33 plays a central role in exacerbation pathogenesis through augmentation of type 2 inflammation. OBJECTIVES To assess whether rhinovirus induces a type 2 inflammatory response in asthma in vivo and to define...
Anti-murine (m) interleukin-5 (IL-5) antibody was found to inhibit eosinophil (Eo) colony formation stimulated by recombinant human (rh) IL-5, but did not inhibit the production of Eo stimulated by rh IL-3 or granulocyte-macrophage colony-stimulating factor (GM-CSF). Conditioned medium (CM) prepared from eosinophilic patients' T cells with interleukin-2 (IL-2) stimulation (T-IL-2-CM), was found...
Accumulating evidence suggests that PD-1, an immuno-inhibitory receptor expressed on activated T cells, regulates peripheral T cell tolerance. In particular, PD-1 is involved in the induction and/or maintenance of T cells' intrinsic unresponsiveness to previously encountered Ags, although the mechanism is yet to be determined. We used a simple experimental model to dissect the mechanism for ane...
Aim. The work aimed to study the nature of changes in endocrine signals (insulin and cortisol) bioactive molecules that control inflammation activation process synthesis (interleukin-2 (IL-2), interleukin-8 (IL-8), vascular endothelial growth factor (VEGF), amino-terminal propeptide type III procollagen (PIIINP)), at initial stage formation chronic wounds experiment.

The Interleukin 2 Receptor α Chain/CD25 Promoter Is a Target for Nuclear Factor of Activated T Cells
The expression of the murine interleukin (IL)-2 receptor alpha chain/CD25 is strongly induced at the transcriptional level after T cell activation. We show here that nuclear factor of activated T cell (NF-AT) factors are involved in the control of CD25 promoter induction in T cells. NF-ATp and NF-ATc bind to two sites around positions -585 and -650 located upstream of the proximal CD25 promoter...
Th17 cells are critically involved in autoimmune disease induction and severity. Recently, we showed that Th17 cells from patients with rheumatoid arthritis (RA) directly induced a proinflammatory loop upon interaction with RA synovial fibroblasts (RASF), including increased autocrine IL-17A production. To unravel the mechanism driving this IL-17A production, we obtained primary CD4(+)CD45RO(+)...
Pregnancy-specific glycoproteins (PSGs) are a family of secreted proteins produced by the placenta, which are believed to have a critical role in pregnancy success. Treatment of monocytes with three members of the human PSGs induces interleukin (IL)-10, IL-6, and transforming growth factor-beta(1) (TGF-beta(1)) secretion. To determine whether human and murine PSGs have similar functions and use...
