Interleukin (IL)-22, a member of the IL-10 cytokine family, has recently gained significant attention as protective principle in murine models of diseases driven by epithelial injury. Alike its biochemical and functional sibling IL-10, IL-22 elicits cellular activation primarily by engaging the signal transducer and activator of transcription (STAT)-3 track of ...

Tenascin-C, a large oligometric glycoprotein of the extracellular matrix, increases the expression of matrix metalloproteinases that lead to plaque instability and rupture, resulting in acute coronary syndrome (ACS). We hypothesized that a high serum tenascin-C level is associated with plaque rupture in patients with ACS. Fifty-two consecutive ACS patients who ...
