KLK4 and asthma: Among pathway maps, we found a series of terms related to HDL-mediated reverse cholesterol transport and lipoprotein metabolism, signaling pathways related to development, disruption of epithelial layer restitution in asthma, blood coagulation, and ECM remodeling, while reported among the process network are inflammation by the Kallikrein-kinin system and IL-6 signaling, iron transport, connective tissue degradation and ECM remodeling, cell adhesion by platelet–endothelium–leucocyte interactions, and again blood coagulation.
