TREM2 and coronary artery disorder: The results showed that the levels of Ctss and Trem2 mRNA were up-regulated as expected after having been induced by LPS plus exosomes from CAD patients (CAD exo) (p < 0.01 vs. control), and miR-4498 mimics down-regulated the levels of both mRNAs (p < 0.01 vs. LPS + CAD exo).
