Differential responses of human monocytes and macrophages to IL-4 and IL-13.
The primary interleukin-4 (IL-4) receptor complex on monocytes (type I IL-4 receptor) includes the 140-kDa alpha chain (IL-4R alpha) and the IL-2 receptor gamma chain, gamma(c), which heterodimerize for intracellular signaling, resulting in suppression of lipopolysaccharide (LPS)-inducible inflammatory mediator production. The activity of IL-13 on human monocytes is very similar to that of IL-4...
متن کاملInduction of functional IL-8 receptors by IL-4 and IL-13 in human monocytes.
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...
متن کاملIL-13 and IL-4 up-regulate cysteinyl leukotriene 1 receptor expression in human monocytes and macrophages.
The cysteinyl (Cys) leukotrienes (LT)C(4), LTD(4), and LTE(4), are lipid mediators that have been implicated in the pathogenesis of asthma. The human LTD(4) receptor (CysLT(1)R) was recently cloned and characterized. The present work was undertaken to study the potential modulation of CysLT(1)R expression by the Th2 cytokines IL-13 and IL-4. In this study, we report that IL-13 up-regulates CysL...
متن کاملIL-3 synergises with basophil-derived IL-4 and IL-13 to promote the alternative activation of human monocytes.
Basophil-derived IL-4 is involved in the alternative activation of mouse monocytes, as recently shown in vivo. Whether this applies to human basophils and monocytes has not been established yet. Here, we sought to characterise the interaction between basophils and monocytes and identify the molecular determinants. A basophil-monocyte co-culture model revealed that IL-3 and basophil-derived IL-4...
متن کاملIL-4 and IL-13 induce Lsk, a Csk-like tyrosine kinase, in human monocytes
Lsk is a protein tyrosine kinase with homology to the COOH-terminal Src kinase (Csk). Unlike Csk that is ubiquitously expressed, Lsk has limited tissue distribution. Here we have examined the expression and regulation of Lsk and Csk in peripheral human monocytes. We have found that Lsk mRNA and protein were not expressed in resting monocytes but were induced by treatment with interleukin 4 (IL-...
