TNF and toxoplasmosis: We found functional relationships among the proteins primarily related to inflammatory and neuronal death mechanisms, including small-cell lung cancer, tuberculosis, AGE-RAGE signaling pathway in diabetic complications, apoptosis, amyotrophic lateral sclerosis, hepatitis B, influenza A, platinum drug resistance, pathways in cancer, colorectal cancer, Kaposi's sarcoma-associated herpesvirus infection, toxoplasmosis, TNF signaling pathway, PD, legionellosis, and p53 signaling pathway.
