Therefore, we examined the mRNA expression of collagen, type VI, alpha 3 (Col6a3), encoding one of the most abundant collagens in the adipose tissue matrix, as well as cell-surface glycoprotein CD44, known to induce immune cell infiltration and to correlate with insulin resistance (Kodama et al., 2012), and also CD68, a macrophage marker. Here, COL6A3 is linked to Insulin resistance.
