The effects of interleukin (IL)-8 on spontaneous IgE and IgG4 production in atopic patients were studied. IL-8 inhibited IgE and IgG4 production by purified surface (s) IgE+ and sIgG4+ B cells, respectively, while it had no effect on IgG1, IgG2, IgG3, IgM, IgA1, and IgA2 production by corresponding sIg+ B cells. The IL-8-induced inhibition was counteracted by IL-6 and tumor necrosis factor-alph...

Background: Acute ischemic stroke (AIS) is closely related to the level of inflammatory factors. This study aimed explore correlation between interleukin-6 (IL-6), interleukin-8 (IL-8), and modified early warning score (MEWS) AIS patients their condition prognosis.

This investigation identifies interleukin 8 (IL-8) as the main inflammatory mediator in head and neck squamous cell carcinoma (HNSCC). The expressions of chemokines of IL-8, IL-1β and IL-6 and the cytokines of tumor necrosis factor-α (TNF-α) were higher in HNSCC patient tissues than in non-cancerous matched tissues (NCMT) whereas the expression of IL-10 was lower. IL-8 is most highly expressed ...

IL-8 and related Glu-Leu-Arg (ELR+) CXC chemokines are potent chemoattractants for neutrophils but not for monocytes. IL-13 and IL-4 strongly increased CXCR1 and CXCR2 chemokine receptor expression in human monocytes, macrophages, and dendritic cells. The effect was receptor- and cell type-selective, in that CCRs were not increased and no augmentation was seen in neutrophils. The effect was rap...

Results IL-8 mRNA expression was variable among the tissue samples and both IL-8 mRNA and protein were variable among the cell lines. In contrast, IL-8 receptor mRNA and protein showed minimal variance. “IL-8 high” and “IL-8 low” groups were defined from the HSA tumor samples based on gene expression profiles. The “IL-8 high” group was associated with a “reactive microenvironment,” showing enri...

Background: It has been established that the level of some inflammatory cytokines increases in celiac disease (CD) and non-celiac gluten sensitivity (NCGS) in comparison with healthy subjects. Therefore, the primary interest in our research was proposing an accurate tool to diagnose patients with CD and NCGS from healthy individuals in an Iranian population. Methods: The serum samples were exam...
