There were a total of ten pneumonia-related pathways, which were TNF signaling, MAPK signaling pathway, chemokine signaling, NF-κB signaling, mTOR signaling, VEGF signaling, autophagy-animal, Toll-like receptor signaling, FoxO signaling, and NOD-like receptor signaling. The gene discussed is VEGFA; the disease is susceptibility to pneumonia measurement.
