Interestingly, the levels of TNF were decreased in the RV of both PAH groups (Figure 3A,E), and the correlation analysis revealed that there is unlikely a link between neither TNF and pThr231/pSer232‐RIP3 nor TNF and pSer345‐MLKL RV levels (Figure 3B,C). Here, TNF is linked to pulmonary arterial hypertension.
