OBJECTIVE IL-8 is a CXC chemokine involved in the pathogenesis of articular damage in rheumatoid arthritis. Local hyperproduction of IL-8 has been suggested to play a role in subchondral bone loss, since it suppresses osteoblast activity and promotes osteoclasts recruitment. Osteoblasts are a source of IL-8; its secretion is regulated by a number of hormones and cytokines. The aim of the presen...

Objective(s): To investigate the efficacy of interleukin 11 (IL-11) towards the high dose methotrexate (HDMTX)-concurrent rat small intestinal mucositis and its impacts on the proliferation of the human T-lymphoblastic leukemia (CEM) cell line. Materials and Methods: 95 Wistar rats were randomly divided into five groups, the normal control group (A), the methotrexate (MTX) control group (B), th...

The anti-inflammatory cytokines are a series of immunoregulatory molecules that control the proinflammatory cytokine response. Cytokines act in concert with specific cytokine inhibitors and soluble cytokine receptors to regulate the human immune response. Their physiologic role in inflammation and pathologic role in systemic inflammatory states are increasingly recognized. Major anti-inflammato...

  Background and Objective: Preterm birth occurs in 8% to 11% of all pregnancies and is responsible for 75% to 80% of all neonatal deaths. Cytokines may be involved in the etiology of preterm birth through their stimulation of prostaglandin synthesis. Cytokines may be released intocervicovaginal fluid during the breakdown of the chorio-decidual adhesion or from an inflammatory reactio...

We investigated the effect of recombinant human interleukin-11 (rhIL-11) on human megakaryocytopoiesis. Nonadherent and T-cell-depleted human bone marrow (BM) mononuclear cells were cultured in a serum-free agar culture system. rhIL-11 alone did not stimulate the growth of human megakaryocyte colonies. However, when rhIL-11 was combined with optimal or suboptimal doses of rhIL-3, the number and...

OBJECTIVE To investigate the possible protective effect of recombinant human interleukin-11 (rhIL-11) against ifosfamide (IFS)-induced hemorrhagic cystitis (HC). MATERIALS AND METHODS Male Swiss mice (20-30g) were pretreated with rhIL-11 (25-625 mg, subcutaneously.) 30 min before intraperitoneal injection of IFS (400 mg/kg) or with saline (control group). Twelve hours later, HC was evaluated ...
