Neuroimmune cross-talk in heart failure

Area of Science:

• Cardiovascular Science
• Neuroimmunology
• Inflammation Research

Background:

• Heart failure (HF) is linked to autonomic nervous system (ANS) imbalance and chronic inflammation.
• Neuroimmune cross-talk (NICT), the interaction between the ANS and immune system (IS), is crucial and potentially altered in HF.
• Neuroinflammation drives HF progression by activating sympathetic nerve activity and impairing the cholinergic anti-inflammatory pathway.

Purpose of the Study:

• To review the role of NICT and neuroinflammation in HF pathophysiology.
• To explore the potential of targeting NICT for HF treatment.
• To highlight current research directions in modulating NICT for improved HF outcomes.

Main Methods:

• Review of existing literature on ANS, IS, and HF.
• Analysis of the mechanisms underlying neuroinflammation in HF.
• Discussion of current and emerging therapeutic strategies targeting NICT.

Main Results:

• Heightened sympathetic activity and parasympathetic withdrawal in HF exacerbate inflammation and cardiac damage.
• Microglial activation and inflammatory molecules contribute to autonomic imbalance and adverse cardiac remodeling.
• Current HF treatments have indirect anti-inflammatory effects, but direct inflammation targeting trials have been inconclusive.

Conclusions:

• NICT plays a significant role in HF progression and is a potential therapeutic target.
• Novel pharmacological and bioelectronic approaches targeting NICT and neuroinflammation are under investigation.
• Further understanding of NICT is essential for developing improved HF therapies.
