A rise in cytoplasmic Ca2+concentration is a key messenger of cell signaling. STIM1 is a sensor of cytoplasmic Ca2+concentration and regulates store-operated calcium entry(SOCE). A strong immunoreactivity of STIM1 was detected aroud aortic plaques in mice. We hypothesize that STIM1 determines whether monocyte differentiates into pro-inflammatory M1 macrophage or anti-inflammatory M2 macrophage. We are verifying it in established monocyte cell lines and human primary monocytes.
