Causal Biological Networks Database
The Epithelial Mucus Hypersecretion network depicts the causal mechanisms that lead to increased expression of MUC5AC and mucus hypersecretion in pulmonary epithelial cells in response to pro-inflammatory signals (e.g. IL13, CCL2, and TNF) and environmental insults. The network also includes COPD-specific signaling components such as various mucins and mucocilliary clearance processes.
