PURPOSE To investigate the association of single-nucleotide polymorphisms (SNPs) in the manganese superoxide dismutase (MnSOD) and two chemokine genes (CCL2 and CCL5) in patients with anterior uveitis (AU). METHODS Seventy-nine Chinese patients with acute AU were recruited, and genotyping of four SNPs including MnSOD 47, CCL2 -2518, CCL2 -2076, and CCL5 -403 alleles was performed with SNP gen...

UNLABELLED Perineural invasion is a form of cancer progression where cancer cells invade along nerves. This behavior is associated with poor clinical outcomes; therefore, it is critical to identify novel ligand-receptor interactions between nerves and cancer cells that support the process of perineural invasion. A proteomic profiler chemokine array was used to screen for nerve-derived factors s...

Salmonella enterica is a gram-negative intracellular pathogen that can cause a variety of diseases ranging from gastroenteritis to typhoid fever. The Typhimurium serotype causes gastroenteritis in humans; however, infection of mice results in an enteric fever that resembles human typhoid fever and has been used as a model for typhoid fever. The present study examined the role of the chemokine C...

Purpose: Though C–C chemokine ligand 2 (CCL2) has been shown to play a pivotal role in prostate cancer tumorigenesis and invasion, the role of inherited variation in the CCL2 gene in prostate cancer progression and metastases remains unanswered. This study is aimed to determine the influence of CCL2 germline variants on prostate cancer aggressiveness. Experimental Design: We performed an associ...

OBJECTIVE To investigate the serum expressions of chemokines CCL2 and CCL3 in patients with rheumatoid arthritis (RA) who were treated with recombinant human interleukin 1 (IL-1) receptor antagonist (IL-1Ra). MATERIAL AND METHODS Serum CCL2 and CCL3 were determined using an enzyme-linked immunosorbent assay in 54 active RA patients before and after treatment with IL-1Ra or a placebo, as well ...

OBJECTIVE To investigate the effect of hyperuricaemia on serum chemokine (C-C motif) ligand 2 (CCL2) levels and blood monocytes in people with gout. METHODS Whole blood was collected from subjects with a history of acute or chronic gout but not currently experiencing an attack of gout, subjects with asymptomatic hyperuricaemia and healthy individuals with normouricaemia. Serum concentrations ...

PURPOSE CCL2 plays an important role in vascular inflammation by inducing leukocyte recruitment and activation. The authors had previously found that the blockade of NAD(P)H oxidase in turn blocks leukocyte adhesion to retinal vessels during diabetes and uveitis. In this study, the role of NAD(P)H oxidase in CCL2 production was assessed. METHODS Studies were performed in three mouse models wi...

Microglia and macrophages are recruited to sites of retinal degeneration where local cytokines and chemokines determine protective or neurotoxic microglia responses. Defining the role of Ccl2-Ccr2 and Cx3cl1-Cx3cr1 signalling for retinal pathology is of particular interest because of its potential role in age-related macular degeneration (AMD). Ccl2, Ccr2, and Cx3cr1 signalling defects impair m...

BACKGROUND Leucocyte activating chemokines such as CCL2, CCL3, and CXCL8 together with proinflammatory IFNgamma, TNFalpha and downmodulatory IL10 play a central role in the restriction of M. tuberculosis infections, but is unclear whether these markers are indicative of tuberculosis disease severity. METHODOLOGY We investigated live M. tuberculosis- and M. bovis BCG-induced peripheral blood m...

Release of pro-inflammatory cytokines from both resident and invading leukocytes within the pancreatic islets impacts the development of Type 1 diabetes mellitus. Synthesis and secretion of the chemokine CCL2 from pancreatic β-cells in response to pro-inflammatory signaling pathways influences immune cell recruitment into the pancreatic islets. Therefore, we investigated the positive and negati...
