Tumor necrosis factor (TNF)-α plays a central role in psoriatic arthritis (PsA). A subgroup of patients with PsA do not respond to anti-TNF-α antibodies but respond to TNF receptor p75-Fc IgG fusion protein (etanercept), which also neutralizes lymphotoxin (LT)-α. It has been suggested that LT-α might be involved in the development of the...

Previous studies have reported the presence of CD86 (B7.2) costimulatory molecule on endothelial cells (ECs) and recent data have shown that CTLA4-Ig (abatacept), used as a biological agent in rheumatoid arthritis, interacts with CD86 expressed on different cells involved in synovitis. Therefore, the effects of CTLA4-Ig/CD86 interaction on...

It has been reported that soluble HLA-G serum levels are increased in patients with pollen-induced allergic rhinitis and decrease after immunotherapy. However, no functional study has been conducted so far. The aim of this study was to evaluate the membrane expression and secretion of HLA-G molecules in peripheral blood mononuclear cells from...

Allergic diseases are sustained by a T-helper 2 polarization leading to interleukin-4 secretion, IgE-dependent inflammation, and mast cell and eosinophil activation. HLA-G molecules, both in membrane-bound and in soluble forms, play a central role in modulation of immune responses. Elevated levels of soluble HLA-G (sHLA-G) molecules are...

BACKGROUND AND PURPOSE: Non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to induce PG-independent anti-inflammatory actions. Here, we investigated the role of three different NSAIDs (naproxen, ibuprofen and oxaprozin) on neutrophil responses to CXCL8 and C5a. EXPERIMENTAL APPROACH: Human neutrophils were isolated from healthy...

Introduction. Pityriasis rosea (PR) is an exanthematous disease related to human herpesvirus- (HHV-) 6/7 reactivation. The network of mediators involved in recruiting the infiltrating inflammatory cells has never been studied. Object. To investigate the levels of serum cytokines, growth factors, and chemokines in PR and healthy controls in...

There is convincing evidence that soluble HLA-A,-B,-C (sHLA-A,-B,-C) and soluble HLA-G (sHLA-G) antigens can induce apoptosis in CD8(+) activated T cells although there is scanty and conflicting information about the mechanism(s) by which sHLA-A,-B,-C antigens and sHLA-G antigens induce apoptosis. In this study we have compared the...
