PURPOSE Several eye diseases are accompanied by inflammatory processes. The authors examined the expression of the proinflammatory chemokine CXCL8 and the corresponding receptors in healthy human retinas, in cellular membranes from patients with proliferative vitreoretinopathy (PVR) or human glial cell cultures and in an animal model of PVR in rabbit eyes. METHODS The authors used immunohisto...

Recent data suggest that chemokines could be essential players in breast carcinogenesis. We previously showed that the CXC chemokine CXCL8 (interleukin-8) was overexpressed in estrogen receptor alpha (ERalpha)-negative breast cell lines. Analysis of CXCL8 chromosomal location showed that several CXC chemokines (CXCL1, CXCL2, CXCL3, CXCL4, CXCL4V1, CXCL5, CXCL6, CXCL7, and CXCL8) were localized ...

Interleukin-8 (IL-8 or CXCL8) is a highly selective pro-inflammatory chemokine, that is elevated in sera of humans and animals with various inflammatory diseases. CXCL8 is possibly involved in uncontrolled inflammation and the development of a systemic inflammatory response syndrome (SIRS) and sepsis. Nevertheless, its behavior and precise properties in the course of inflammation are not fully ...

At present, diagnosis for neurosyphilis remains a major clinical challenge. Venereal Disease Research Laboratory (VDRL) titer of the cerebrospinal fluid (CSF) is suboptimally sensitive to diagnose neurosyphilis, which can be negative in neurosyphilis patients, especially in asymptomatic neurosyphilis patients. In the search for biomarkers of neurosyphilis, we investigated the chemokine profile ...

Accumulating data now suggest that ZO-1, once delocalized from tight junctions, could be implicated in the regulation of tumor-promoting genes. Because of theirmajor implication in different steps of tumor progression, we investigated here the influence of ZO-1 on chemokines expression in breast cancer cells. Using GeneArray analysis to compare chemokine mRNA expression in breast tumor cells tr...

INTRODUCTION Gastric cancer is one of the most common cancer-related causes of death. This is mainly due to the lack of good noninvasive method/biomarkers suitable for early-tumour diagnosis and planning of further therapy modalities. Chemokines play an important role in cancer progression and metastasis formation. In gastric cancer patients, clinical relevance of CXCL12 and CCL5 level has been...

Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infection in young infants worldwide. Previous studies have reported that the induction of interleukin-8/CXCL8 and RANTES/CCL5 correlates with disease severity in humans. The production of these chemokines is elicited by viral replication and is NF-kappaB dependent. RSV, a negative-sense single-stranded RNA virus,...

CC and CXC chemokines coinduced in fibroblasts and leukocytes by cytokines and microbial agents determine the number of phagocytes infiltrating into inflamed tissues. Interleukin-8/CXCL8 and stromal cell-derived factor-1/CXCL12 significantly and dose-dependently increased the migration of monocytes, expressing the corresponding CXC chemokine receptors CXCR2 and CXCR4, toward suboptimal concentr...

BACKGROUND Angiogenesis may play a role in the pathogenesis of Non-Small Cell Lung cancer (NSCLC). The CXC (ELR(+)) chemokine family are powerful promoters of the angiogenic response. METHODS The expression of the CXC (ELR(+)) family members (CXCL1-3/GROα-γ, CXCL8/IL-8, CXCR1/2) was examined in a series of resected fresh frozen NSCLC tumours. Additionally, the expression and epigenetic regula...
