Cardiac lymphatic dysfunction and repair in cardiovascular disease

Area of Science:

• Cardiovascular Research
• Lymphatic Biology

Background:

• Cardiac lymphatic research has significantly advanced, revealing lymphatic remodelling in cardiovascular diseases.
• Structural alterations in cardiac lymphatics often lead to impaired lymphatic transport and dysfunction.

Purpose of the Study:

• To summarize current knowledge on cardiac lymphatics, their homeostatic functions, and alterations in cardiovascular diseases.
• To present recent findings on inflammation's effects on lymphatics and their role in cardiac immunity.
• To discuss cardiac lymphangiogenesis regulation and therapeutic strategies.

Main Methods:

• Review of current literature on cardiac lymphatic structure, function, and disease.
• Analysis of experimental and clinical studies on lymphatic remodelling and transport.
• Synthesis of research on lymphangiogenesis, immune cell-lymphatic crosstalk, and therapeutic approaches.

Main Results:

• Cardiac lymphatics exhibit specialized structures and molecular features crucial for myocardial fluid balance, immune microenvironment, collagen turnover, and lipid handling.
• Lymphatic dysfunction in cardiovascular diseases affects multiple pathophysiological aspects.
• Inflammation significantly impacts lymphatic function and immune modulation within the heart.
• Cardiac lymphangiogenesis is regulated by immune cell crosstalk, metabolic, and biomechanical stimuli.

Conclusions:

• Cardiac lymphatics play a critical role in cardiovascular health, and their dysfunction contributes to disease pathophysiology.
• Further research into lymphatic imaging and lymphangiogenic therapies holds promise for clinical translation in cardiovascular disease patients.
• Understanding immune cell-lymphatic interactions is crucial for developing novel therapeutic strategies.
