Abstract

IL-33 is a chromatin-associated cytokine of the IL-1 family that has recently been linked to many diseases, including asthma, rheumatoid arthritis, atherosclerosis, and cardiovascular diseases. IL-33 signals through the IL-1 receptor-related protein ST2 and drives production of pro-inflammatory and T helper type 2-associated cytokines in mast cells, T helper type 2 lymphocytes, basophils, eosinophils, invariant natural killer T cells, and natural killer cells. It is currently believed that IL-33, like IL-1beta and IL-18, requires processing by caspase-1 to a mature form (IL-33(112-270)) for biological activity. Contrary to the current belief, we report here that full-length IL-33(1-270) is active and that…
