Neural-immune-cardiovascular axis emerges as therapeutic target in atherosclerosis, hypertension, heart failureNew pathways link nerves and immunity in heart disease

AI-generated summary of the cited source, checked by automated accuracy review. How we work

Key Takeaway
Interpret the neural-immune-cardiovascular axis as a mechanistic framework, not yet a basis for clinical intervention.

This systematic review examines the role of the neural-immune-cardiovascular axis in cardiovascular homeostasis and pathogenesis. It focuses on signaling pathways and crosstalk mechanisms involved in atherosclerosis, hypertension, and heart failure. The authors identify potential therapeutic targets based on these interactions.

The review synthesizes qualitative evidence on how neural and immune signals integrate with cardiovascular function. It discusses mechanisms such as inflammatory reflex pathways and neuro-immune modulation that may contribute to disease progression. However, no pooled effect sizes or quantitative outcomes are reported.

Limitations are not explicitly reported in the source. The review is mechanistic in nature, and the authors do not provide direct evidence linking these pathways to clinical endpoints. The findings are intended to inform future therapeutic development rather than immediate practice changes.

Clinicians should interpret these results as hypothesis-generating. The neural-immune-cardiovascular axis represents an emerging area of research, but no specific interventions or clinical recommendations can be derived from this review alone.

How this fits prior evidence

This systematic review extends prior coverage of shared pathophysiology in cardiometabolic disease by focusing on the neural-immune-cardiovascular axis. It complements the unified cardiometabolic disease framework linking T2DM, ASCVD, HFpEF, MASLD, hypertension, and CKD, and the gut microbiota–immune axis in atherosclerosis, by adding neuro-immune signaling as another mechanistic layer. The review does not provide clinical outcome data, contrasting with prior findings such as the 39% prevalence of cognitive impairment in heart failure or the benefit of mHealth-supported cardiac rehabilitation.

Living with heart issues often feels like a constant battle against several different systems in the body. New research is looking closer at how these systems actually talk to each other. Specifically, experts are studying the neural-immune-cardiovascular axis. This is a complex way of saying that your nerves and your immune system work together to keep your heart and blood vessels healthy.

This review looked at how these communication pathways might play a role in common conditions like atherosclerosis (hardened arteries), hypertension (high blood pressure), and heart failure. By mapping out these signals, researchers hope to find new ways to treat patients who currently have limited options for managing their symptoms.

It is important to note that this research focuses on the underlying biology of how the body works. It identifies potential targets for future medicines rather than testing specific drugs or showing immediate clinical results. While it offers a roadmap for new treatments, these therapies are still in the early stages of development.

What this means for you:
The link between nerves and immune cells may offer new ways to treat heart failure and high blood pressure.

Common questions

What is the neural-immune-cardiovascular axis?

This term describes the way your nerves, immune system, and cardiovascular system work together. These three systems talk to each other through specific signaling pathways. This communication helps maintain balance in your body, but when these signals go wrong, it can lead to issues like high blood pressure or heart failure.

How does this research help people with heart disease?

By identifying the specific ways nerves and immune cells interact, researchers can find new targets for medicine. This work aims to create better ways to treat atherosclerosis, hypertension, and heart failure by addressing the underlying biological signals that contribute to these conditions.

The neural-immune-cardiovascular axis represents an emerging and highly integrated physiological and pathophysiological concept, describing a complex bidirectional communication network between the nervous, immune, and vascular systems. This review systematically examines the pivotal role of this axis in maintaining cardiovascular homeostasis and in the pathogenesis of cardiovascular diseases. We first provide an overview of the fundamental signaling pathways between the components of this axis. Subsequently, we delve into the specific crosstalk mechanisms within the axis in the context of major cardiovascular conditions, including atherosclerosis, hypertension, and heart failure. A central focus is placed on critically evaluating the potential therapeutic targets and intervention strategies that have emerged from our understanding of this axis’s mechanisms. This review aims to provide a comprehensive perspective for understanding the multi-system pathogenesis of cardiovascular diseases and for informing the development of novel therapeutic approaches.
