The cytokines interleukin 13 and 4 share a common heterodimeric receptor and are important modulators of peripheral allergic reactions. Produced primarily by T-helper type 2 lymphocytes, they are typically considered as anti-inflammatory cytokines because they can downregulate the synthesis of T-helper type 1 pro-inflammatory cytokines. Their presence and role in the brain is only beginning to ...

Interleukins represent a class of immunomodulatory cytokines, small intercellular signaling proteins, that are critically involved in the regulation of immune responses. They are produced in large amounts by various cell types during inflammatory reactions, and the balance of cytokines determines the outcome of an immune response. Therefore, cytokines are regarded as interesting therapeutic tar...

introduction:to evaluate the role of allergic-type and infectious-type cytokines in children with chronic otitis media with effusion (ome) materials and methods:we investigated serum levels of interleukins (il)-4, il-5, and il-13, along with interferon-gamma (ifn-γ) and tumor necrosis factor-alpha (tnf-α), by enzyme-linked immunosorbent assay (elisa) in 35 children with ome and 28 healthy contr...
