The role of temporal changes of pro-inflammatory cytokines in the development of adverse cardiac remodeling after ST-elevation myocardial infarction.

Introduction: Increasing evidence supports the view that pro-inflammatory cytokines play a role in fibrosis after myocardial infarction (MI). It has been suggested that interleukin (IL)-12p40, a pro-inflammatory cytokine, can induce interferon γ (IFN-γ) and matrix metalloproteinase (MMP). However, the role of IL-12p40 in adverse cardiac remodeling (AR) after ST-elevation MI (STEMI) is unclear.

The small GTPase regulatory protein Rac1 drives podocyte injury independent of cationic channel protein TRPC5.

Transient receptor potential canonical channels (TRPCs) are non-selective cationic channels that play a role in signal transduction, especially in G -protein-mediated signaling cascades. TRPC5 is expressed predominantly in the brain but also in the kidney. However, its role in kidney physiology and pathophysiology is controversial.
