TNFRSF1A and Pleural effusion: On the contrary, genes associated with the nuclear factor (NF)-κB pathway were down-regulated, including NFKB1, NFKB2, TNFR1, IL1B, IL8, and TNFA. Many of these NF-κB pathway–related genes, but not IFNG or IL12A, correlated with adverse clinical events such as development of pleural effusion and hemorrhagic manifestations.
