FPR2 and geroderma osteodysplastica: Based on the regulatory function of FPR2 and miR-27b and the mechanism of ceRNA, we speculate that LINC01820:13 reduces the inhibitory effect of miR-27b on FPR2 by competitively binding to the RISC of miR-27b, thereby upregulating the expression of FPR2 and leading to an autoimmune response and inflammation in GO patients.
