Background and Objective: Oxidative stress induced by proinflammatory cytokines such as IL-1β plays a major role in β-cell destruction in diabetes type 1. Salvianolic acid B (Sal B) is a polyphenolic compound with antioxidant and protective effects. Thus, objective of this study was to assess the protection exerted by Sal B on isolated rat islets exposed to IL-1β and to investigate an underlyin...

Background and Objective: Host genetic factors such as cytokine gene polymorphisms as well as Helicobacter pylori (H. pylori) infection have been found to be associated with gastric cancer risk . Interleukin 1 is a pro-inflammatory cytokine involved in H. pylori-induced gastric inflammation. Therefore, w...

Palmitoleic acid (PMA) has anti-inflammatory and antidiabetic activities. Here we tested whether these effects of PMA on glucose homeostasis and liver inflammation, in mice fed with high-fat diet (HFD), are PPAR-α dependent. C57BL6 wild-type (WT) and PPAR-α-knockout (KO) mice fed with a standard diet (SD) or HFD for 12 weeks were treated after the 10th week with oleic acid (OLA, 300 mg/kg of b....

Receptor activator of nuclear factor κ B ligand (RANKL) plays a crucial role in the bone erosion of rheumatoid arthritis (RA) by prompting osteoclastogenesis. Considering that 1,25(OH)2D3 has been suggested as a potent inducer of RANKL expression, it should clarify whether vitamin D supplement could result in RANKL overexpression and thereby facilitate excessive osteoclastogenesis and bone reso...

The interleukin 1 receptor antagonist (IL1Ra) family of molecules now includes one secreted isoform (sIL1Ra) and three intracellular isoforms (icIL1Ra1, 2, and 3). Extensive evidence indicates that the sole biological function of sIL1Ra seems to be to competitively inhibit IL1 binding to cell-surface receptors. Although intracellular IL1Ra1 may be released from keratinocytes under some conditio...

BACKGROUND Allergic rhinitis is a complex polygenic disorder of the upper respiratory tract. Given that proinflammatory cytokines such as tumor necrosis factor (TNF) and interleukin (IL) 1 seem to play a role in the development of allergic rhinitis, we evaluated the associations between various single-nucleotide polymorphisms (SNPs) of the TNF and IL1 genes in a case-control study. METHODS Th...

The aim of this study was to analyze the association between single nucleotide polymorphism (SNP) in IL1B (rs1143 634) and IL1RN (rs2234677) with chronic low back pain (LBP) in chronic post-traumatic stress disorder (PTSD). A total of 406 war veterans from 1991-1995 war in Croatia participated in this study. They were divided into four groups, according to psychiatric interview, psychometric te...

Glandular secreting trichomes of cultivated tomato (Solanum lycopersicum) and close relatives produce a variety of structurally diverse volatile and non-volatile specialized ('secondary') metabolites, including terpenes, flavonoids and acyl sugars. A genetic screen is described here to profile leaf trichome and surface metabolite extracts of nearly isogenic chromosomal substitution lines coveri...

IL-1 has served as a ground breaking molecule in immunology and it is now experiencing a renaissance. Originally the description of a cytokine acting at vanishingly low concentration on cells and organs as diverse as the hypothalamus (fever) and T cells (1) was without precedent in biology and paved the way to the whole field of cytokines and their pleiotropic mode of action. The discovery of t...

Objective: Asphyxia  is  a  major  cause  of  acute  mortality  and  chronic  neurologic  disability  in  neonates. We sought to  define  the  predictive  values  of  serum  concentrations  of  interleukin-1β  in  newborns  with perinatal asphyxia to see if there is a relation between interleukin-1β (IL-1β) levels to the short term neurological deficit.  Methods: This was a prospective (case-co...
