CCL2 and infection: Indeed, for a set of miRNAs, let-7a, miR-25, miR-26a, miR-132, miR-140, miR-146a, and miR-155, their upregulation in L. major-infected human macrophages was negatively correlated with the expression of their corresponding chemokine targets, CCL2, CCL5, CXCL10, CXCL11, and CXCL12, thereby corroborating the data that indicate the downregulation of chemokines CCR2, CCL5, and CXCL10 during infection [81].
