OBJECTIVE Based on the reported association between cytokines with depression and suicide, and evidence of increased markers of inflammation in the brain of suicide victims, the present study examined the expression of cytokines in the orbitofrontal cortex of suicide victims. METHOD In a postmortem sample obtained from the Brodman area 11 of suicides (n = 34) and controls (n = 17), real-time ...

The activating and inhibitory cytokine signals that act upon epithelial cells in the human lung are critically important for controlling the production of inflammatory mediators from those cells in the context of allergic disease. The cytokines interleukin (IL)-4 and IL-13, derived from T helper (Th)-2 cells and other cell types, are potent inducers of epithelial cell expression of a host of in...

Heat shock protein 90 (HSP90) is a molecular chaperone that folds and promotes the activity of wide range client proteins, including key signaling proinflammatory molecules involved in aberrant inflammation. RGRN-305 novel HSP90 inhibitor has been reported to exhibit antiinflammatory properties autoimmune skin diseases. Here, effects were investigated vitro mouse model vivo. In primary human ke...

Atopic dermatitis (AD) is a chronic, pruritic, and allergic skin disease in humans and animals, particularly dogs. Canine AD (cAD) has received attention as a spontaneous atopic animal model because domesticated dogs inhabit a human environment, and cAD shares several clinicopathological features with human AD (hAD). In hAD, periostin (PO) is suggested to play a critical role in the enhancement...

Background: Grass pollen immunotherapy is highly effective in reducing seasonal hay fever symptoms and medication requirements. Clinical improvement is accompanied by a reduction in nasal mucosal eosinophils, although the mechanism is unknown. Methods: Nasal biopsies were taken from 37 adults before immunotherapy and during the peak pollen season following 2 years treatment. Biopsies were proce...

IL-1 stimulates mesangial cells to synthesize specific proteins, including a non-pancreatic (Type II) phospholipase A2 (PLA2). We have studied the regulation of PLA2 by proinflammatory mediators, implicated in the pathogenesis of glomerulonephritis, and have assessed whether the activation of second messenger systems modulates or mimics PLA2 gene expression by cytokines. IL-1 alpha and beta, TN...

AIMS To determine the expression of parathyroid hormone related protein (PTHrP) and interleukin-6 (IL-6) mRNAs and their possible relation in malignant tumours, derived from patients with and without hypercalcaemia, commonly associated with humoral hypercalcaemia of malignancy. METHODS PTHrP and IL-6 mRNA expression was studied by northern blot analysis in tumour specimens from 13 consecutive...

Background: IL-6 is a proinflammatory and immunoregulatory cytokine to be very high in endometriosis and pelvic inflammatory disease, which are known risk factors for ectopic pregnancy(EP). The effects of IL-6 on target cells occur via the formation of a high-affinity complex with IL-6Ra that expressed in the cilia of the epithelial cells. In the present study,we compared expression of IL-6Ra i...

Cryostat sections from skin biopsies from 24-h allergen-induced late-phase cutaneous reactions (LPR) in 14 human atopic subjects were hybridized with 35S-labeled RNA probes for a number of cytokines. mRNA was detected for interleukin 3 (IL-3) (8/14), IL-4 (10/14), IL-5 (11/14), and granulocyte/macrophage colony-stimulating factor (GM-CSF) (13/14). Only 5 of 14 gave hybridization signals for IL-...

In schistosomiasis, chronic parasite egg-induced granuloma formation can lead to tissue destruction and fibrosis, which causes much of the morbidity and mortality associated with this disease. Here we show the importance of IL-13 in the pathogenesis of schistosomiasis, and demonstrate, perhaps for the first time, the therapeutic efficacy of an IL-13 inhibitor, sIL-13Ralpha2-Fc, in the control o...
