ABSTRACT
Atherosclerosis is definitely considered as an inflammatory/immunopathological disease. The long-standing low-grade inflammation is focused on the components of the vessel wall. Initially, this inflammation was assumed to be driven by the pro-inflammatory Th1 cellular and cytokine immune responses. On the basis of accumulating knowledge, however, this view has been specified to include the Th17/Th1 axis which underlies most immunopathological diseases accompanied by sterile inflammation. On the other hand, an anti-inflammatory Th2 cellular and cytokine immune response attempts to dampen these unfavorable reactions which terminate in full-blown atherosclerosis. Interleukin-33, the novel member of the IL-1 cytokine superfamily, was suggested to take part in the anti-atherogenic response by mediating the Th1-to-Th2 switch of the immune reactions. However, IL-33 is a multifaceted mediator with both pro- and anti-inflammatory activities. IL-33 presents both an extracellular (cytokine-like) and a nuclear-bound (transcription factor-like) form, each of them performing distinct activities of their own. This review article summarizes latest data relevant to IL-33's role in atherosclerosis, underscoring the paradoxes and pitfalls of laboratory findings and their extrapolation to live organisms including humans.

    Interleukin-1R like receptors (ILRs) and Toll Like Receptors (TLRs) are key receptors of innate immunity, inflammation, and orientation of the adaptive response. They belong to a superfamily characterized by the presence of a conserved intracellular domain, the Toll/IL-1R (TIR) domain, which is...

    Background Interleukin-33 (IL-33) is a novel cytokine that triggers inflammatory immune responses, but evidence of its role in human asthma, a common allergic airway disease, is lacking. There is also a paucity of information regarding which cells express IL-33, and what conditions promote its...

    Interleukin (IL) 33, a member of IL-1 cytokine family, is well known to promote Th2 type immune responses by signaling through its receptor ST2. However, it is not clear whether ST2 is expressed by mucosal epithelium, and how it responds to IL-33 to induce inflammatory mediators. This study was...
