KIRREL2 and infection: Other adhesion molecules, such as those belonging to the CAM and GPCR families, were also affected by infection, including a lower expression of vascular cell adhesion molecules 1 (VCAM1), Kirre-like nephrin family adhesion molecule 2 (KIRREL2), adhesion G protein-coupled receptors (ADGR)-D1, ADGRF5, and ADGRV1, and a higher expression of ADGRF1.
