The Pathology of the IL-33/T1/ST2 Pathway: Harmin’ Alarmin

Posted by MD Biosciences on Aug 10, 2015 5:30:00 PM

IL-33 is a member of the IL-1 cytokine family that is expressed constitutively in the nucleus of epithelial and endothelial cells as well as in CNS oligodendrocyte and astrocyte cells (1-2). Its release in response to cell damage and/or death has earned it the classification of “alarmin” – an immunological alarm signal that is released in times of cellular distress (3-4). Upon release, IL-33 binds to the T1/ST2 and IL-1R accessory protein (IL-1RAP) heterodimer complex to activate the MYD88-dependant signaling pathway (1).

Studies targeting the function of IL-33 and/or signaling through its T1/ST2 receptor have highlighted the dual role this versatile cytokine pathway plays in the induction inflammatory immune reactions. More interestingly, these reactions can be either beneficial or pathological in nature. Here we will discuss the pathological role of IL-33 in disease.

IMQ-induced Psoriasis Model | Correlates with Human Psoriasis

Posted by MD Biosciences on Apr 29, 2013 5:28:00 PM

First let's start by talking about what makes a good preclinical model of psoriasis?

A good pre-clinical psoriasis model should obviously re-capitulate the key features of the clinical disease in humans. Therefore, a plausible model will exhibit the following criteria:
