IL-4 and IL-4 Receptor Expression Is Dispensable for the Development and Function of Natural Killer T Cells

IL-4 and IL-4 Receptor Expression Is Dispensable for the Development and Function of Natural Killer T Cells

CD4 T cells acquire functional properties including cytokine production upon antigenic stimulation through the T cell receptor (TCR) and differentiate into T helper (Th) cells. Th1 cells produce interferon (IFN)-γ and Th2 cells produce interleukin (IL)-4. Th1 and 2 cells utilize IFN-γ and IL-4 for further maturation and maintenance, respectively. Promyelocytic leukemia zinc finger (PLZF)-expres...

V75R576 IL-4 Receptor Is Associated with Allergic Asthma and Enhanced IL-4 Receptor Function

association of the expression of il-4 and il-13 genes, il-4 and ige serum levels with allergic asthma

immune and inflammatory responses mediated by cytokines, play important roles in the pathophysiology of asthma. these responses are associated with overexpression of th2 cytokines such as il-4 and il-13. these two cytokines use common receptors for signaling that lead to identical immunological effects and regulation of the th1/th2 balance. the aim of this study was to determine whether patient...

Human natural killer cells exposed to IL-2, IL-12, IL-18, or IL-4 differently modulate priming of naive T cells by monocyte-derived dendritic cells.

Dendritic cells (DCs) play a crucial role in naive T-cell priming. Recent data suggested that natural killer (NK) cells can influence the capability of DCs to promote Th1 polarization. This regulatory function is primarily mediated by cytokines released in the microenvironment during inflammatory responses involving NK cells. In this study, we show that human NK cells exposed for short time to ...

Interleukin-4 (IL-4) receptor expression on human T cells is affected by different intracellular signaling pathways and by IL-4 at transcriptional and posttranscriptional level.

Interleukin-4 (IL-4) modulates the survival, proliferation, and differentiation of a variety of hematopoietic cells. The effects are mediated through a single class of high-affinity receptors for IL-4. To understand the biologic effects of IL-4 on human T cells, we studied the regulation of IL-4 receptor (IL-4R) gene expression. We showed that IL-4R mRNA accumulation in human T cells is enhance...
