Radiation-induced intestinal injury (RIII) commonly occurs in patients who received radiotherapy for pelvic or abdominal cancer, or who suffered from whole-body irradiation during a nuclear accident. RIII can lead to intestinal disorders and even death given its integrity damage that results from intestinal stem cell (ISC) loss. Recovery from RIII relies on the intensity of supportive treatment, which can attenuate lethal infection and give surviving stem cells an opportunity to regenerate. It has been reported that RSPO1 is a cytokine with potent and specific proliferative effects on intestinal crypt cells...

OBJECTIVE: Interleukin-6 (IL-6) plays a crucial role in the pathogenesis of rheumatoid arthritis (RA). Both fulfillment of remission criteria and assessment of other methods of evaluation of RA are important for preventing joint damage progression. Measurement of serum IL-6 concentrations has been reported to be useful for monitoring RA disease activity. However, it takes at least 4-5h to measure serum IL-6 concentrations using traditional methods, which limits its utility during routine assessment in daily clinical practice settings...

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis. Chemokines play important roles in the progression of many malignancies; however, the role of chemokine receptor expression in clinical cases of PDAC is unclear. Moreover, little is known about DARC, a decoy receptor of CXC chemokines, in the regulation of tumor progression. METHODS: Functions of chemokine receptors were evaluated using surgical specimens collected from PDAC patients, and PDAC cell lines...

Infiltration of leukocytes is one of the hallmarks of the inflammatory response. Among the leukocyte populations, neutrophils are the first to infiltrate, followed by monocytes and lymphocytes, suggesting the presence of mediators that specifically recruit these cell types. Cytokine-like chemoattractants with monocyte chemotactic activity, such as lymphocyte-derived chemotactic factor (LDCF) or tumor-derived chemotactic factor (TDCF), were reported as molecules that could play a critical role in the recruitment of monocytes into sites of immune responses or tumors; however, their identities remained unclear...

Endotoxin, or LPS tolerance, is an immunomodulatory mechanism that results in a significantly diminished response to secondary LPS exposure, which may serve to protect the host against endotoxic shock. Type I interferons (IFNs) are cytokines released upon LPS binding to TLR4 and have been shown to have immunomodulatory properties. Due to this regulatory function of type I IFN, we aimed to investigate the role of type I IFN signalling in LPS tolerance. Our data suggests that type I IFN does not play a role in LPS tolerance in vitro, as both wild type and IFNAR1(-/-) peritoneal macrophages showed reduced cytokine production after secondary LPS exposure...

β2-receptor agonists are used in the treatment of inflammatory obstructive lung diseases asthma and COPD as a symptomatic remedy, but they have been suggested to possess anti-inflammatory properties, also. β2-receptor activation is considered to lead to the activation of ERK pathway through G-protein- and cAMP-independent mechanisms. In this study, we investigated the effects of β2-receptor agonists salbutamol and terbutaline on the production of inflammatory factors in macrophages. We found that β2-receptor agonists inhibited LPS-induced ERK phosphorylation and the production of MCP-1...

Deregulated gp130-dependent STAT3 signalling by the pleiotropic cytokine interleukin (IL)-11 has been implicated in the pathogenesis of gastric cancer (GC), the third most common cancer worldwide. While the IL-11-gp130-STAT3 signalling axis has traditionally been thought to exclusively use the membrane-bound IL-11 receptor (mIL-11R), recent evidence suggests that mIL-11R can be proteolytically cleaved to generate a soluble form (sIL-11R) which can elicit trans-signalling. Since the role of IL-11 trans-signalling in disease pathogenesis is unknown, here we have employed the IL-11-driven gp130(F/F) spontaneous model of GC to determine whether IL-11 trans-signalling promotes gastric tumourigenesis...

In humans, S100A12 (also named Calgranulin C and EN-RAGE) is mainly expressed and secreted by neutrophil granulocytes. Extracellular S100A12 is involved in innate immune responses against microorganisms and parasites. S100A12 is a ligand for the receptor for advanced glycation end products (RAGE), which is a cell surface receptor on macrophages, endothelium, and lymphocytes. In a recent study, Realegeno et al. showed that S100A12 exerts antimicrobial activity against Mycobacterium leprae in infected human macrophages...

Astrocytes play a pivotal role in neuronal survival under the condition of post-ischemic brain inflammation, but the relevant astrocyte-derived mediators of ischemic brain injury remain to be defined. IL-15 supports survival of multiple lymphocyte lineages in the peripheral immune system, but the role of IL-15 in inflammatory disease of the central nervous system is not well defined. Recent research has shown an increase of IL-15-expressing astrocytes in the ischemic brain. Since astrocytes promote neuron survival under cerebral ischemia by buffering excess extracellular glutamate and producing growth factors, recovery of astrocyte function could be of benefit for stroke therapy...

Hepatocyte growth factor (HGF) is a pleiotropic cytokine composed of an α-chain and a β-chain, and these chains contain four kringle domains and a serine protease-like structure, respectively. The receptor for HGF was identified as the c-met proto-oncogene product of transmembrane receptor tyrosine kinase. HGF-induced signaling through the receptor Met provokes dynamic biological responses that support morphogenesis, regeneration, and the survival of various cells and tissues, which includes hepatocytes, renal tubular cells, and neurons...
