The interest in analysing antigen-specific cytokine responses has substantially increased in recent years, in part due to their use in assessing vaccine efficacy. In the present study, the kinetics of IL-2, IL-4 and IFN-γ expression was determined in bovine PBMCs by real-time PCR and in whole blood by cytokine-release assay after in vitro stimulation with recall foot-and-mouth disease virus (FMDV)...
Protective immunity against enteric parasitic nematodes is dependent on IL-4, IL-13 activation of their exclusive transcription factor STAT6. The precise pathways by which enteric parasitic nematodes are recognized by the host is unclear, but elimination of this important interaction in developed nations is thought to contribute to the dysregulated immune responses that are a characteristic of autoimmune...
Aberrant production of the prototypical type 2 cytokines, interleukin (IL)-4 and IL-13 has long been associated with the pathogenesis of allergic disorders. Despite tremendous scientific inquiry, the similarities in their structure, and receptor usage have made it difficult to ascertain the distinct role that these two look-alike cytokines play in the onset and perpetuation of allergic inflammation...
Type 2 immune responses are defined by the cytokines interleukin 4 (IL-4), IL-5 and IL-13 and the cellular and physiological changes that these cytokines induce, including IgE production, eosinophilia, mast cell degranulation, mucus secretion and smooth muscle contraction. Together these responses provide a “weep and sweep” reflex that is optimised to expel parasitic worms. The same response can also...
IL-4 was identified as the first cytokine to be produced by mast cells and is responsible for promoting mast cell IL-13 production. IL-4 and IL-13 play a prominent role in stimulating and maintaining the allergic response. As closely related genes, IL-4 and IL-13 share a common receptor subunit, IL-4Rα, necessary for signaling. Here we summarize the literature on mast cell activation associated with...
