| Summary: | Abstract Macrophages are crucial in the heart’s development, function, and injury. As part of the innate immune system, they act as the first line of defense during cardiac injury and repair. After events such as myocardial infarction or myocarditis, numerous macrophages are recruited to the affected areas of the heart to clear dead cells and facilitate tissue repair. This review summarizes the roles of resident and recruited macrophages in developing cardiovascular diseases. We also describe how macrophage phenotypes dynamically change within the cardiovascular disease microenvironment, exhibiting distinct pro-inflammatory and anti-inflammatory functions. Recent studies reveal the values of targeting macrophages in cardiovascular diseases treatment and the novel bioengineering technologies facilitate engineered macrophages as a promising therapeutic strategy. Engineered macrophages have strong natural tropism and infiltration for cardiovascular diseases aiming to reduce inflammatory response, inhibit excessive fibrosis, restore heart function and promote heart regeneration. We also discuss recent studies highlighting therapeutic strategies and new approaches targeting engineered macrophages, which can aid in heart injury recovery. |
