In atopic dermatitis (AD), skin infiltrating leukocytes are mainly Type 2 lymphocytes that produce IL-4 and IL-13, thus AD is classified as a disease; however, in the actual inflammation, 1 3 cells, well lymphocytes, intermingle inflamed lesions. Here, using mouse model of which caspase-1 was specifically amplified under keratin 14 induction, we analyzed sequential changes 1, 2, inflammatory cy...

The present study was designed to explore the interaction of interleukin-13 (IL-13) with vascular endothelial cells (EC). In vitro exposure to IL-13 of human umbilical vein EC induced surface expression of vascular cell adhesion molecule-1 (VCAM-1). At optimal concentrations (10 to 50 ng/mL) and exposure times (24 hours), IL-13 was a twofold to threefold less effective inducer of VCAM-1 than IL...

Interleukin-l3 (IL-13) is a recently discovered immunoregulatory cytokine. The cellular sources of IL-13 and the regulation of its expression are largely unknown. Here we show that human basophils produce IL-13 in response to IgE-receptor (IgER) crosslinking, IL-3, IL-3 plus C5a. but not C5a alone. Human basophils express IL-13 in a restricted manner since, apart from IL-4, no other cytokines e...

IL-13 has a prominent role in host defense against the gastrointestinal nematode Nippostrongylus brasiliensis; however, the role of IL-13Ralpha2 in the immune and functional response to enteric infection is not known. In the current study, we investigated changes in smooth muscle and epithelial cell function as well as alterations in gene expression of IL-13 and IL-4 and their receptors using l...

We have recently reported that excessive synthesis of proinflammatory cytokines such as interleukin-6 (IL6) and IL-8 may play a role in the pathogenesis of mesenteric infarction. IL-4, IL-10 and IL-13 are classified as anti-inflammatory cytokines because they reduce the secretion of proinflammatory cytokines by stimulated monocytes/macrophage. During several inflammatory states anti-inflammator...

Particle inhalation-induced lung inflammation acts as an adjuvant to allergens or respiratory viral infection in a process that is mediated by macrophages and epitheliums. The production of interleukin (IL)-4 and IL-13 by activated T cells is involved in the augmentation of Th2-type immune responses to particles, and IL-25 induces the synthesis of IL-4 and IL-13. However, whether IL-13 and IL-2...
