Despite the advances in treatment options, cardiovascular disease (CVDs) remains the leading cause of death over the world. Chronic inflammatory response and irreversible fibrosis are the main underlying pathophysiological causes of progression of CVDs. In recent decades, cardiac macrophages have been recognized as main regulatory players in the development of these complex pathophysiological conditions. Numerous approaches aimed at macrophages have been devised, leading to novel prospects for therapeutic interventions. Our review covers the advancements in macrophage-centric treatment plans for various pathologic conditions and examines the potential consequences and obstacles of employing macrophage-targeted techniques in cardiac diseases.

Adoptive transfer of genetically or nanoparticle-engineered macrophages represents a promising cell therapy modality for treatment of solid tumor. However, the therapeutic efficacy is suboptimal without achieving a complete tumor regression, and the underlying mechanism remains elusive. Here, we discover a subpopulation of cancer cells with upregulated CD133 and programmed death-ligand 1 in mouse melanoma, resistant to the phagocytosis by the transferred macrophages.

Vulnerable plaques, which are high-risk features of atherosclerosis, constitute critical elements in the disease's progression due to their formation and rupture. Macrophages and macrophage-derived foam cells are pivotal in inducing vulnerability within atherosclerotic plaques. Thus, understanding macrophage contributions to vulnerable plaques is essential for advancing the comprehension of atherosclerosis and devising novel therapeutic and diagnostic strategies.

Most chronic respiratory diseases often lead to the clinical manifestation of pulmonary fibrosis. Inflammation and immune disorders are widely recognized as primary contributors to the onset of pulmonary fibrosis. Given that macrophages are predominantly responsible for inflammation and immune disorders, in this review, we first focused on the role of different subpopulations of macrophages in the lung and discussed the crosstalk between macrophages and other immune cells, such as neutrophils, regulatory T cells, NKT cells, and B lymphocytes during pulmonary fibrogenesis.

Macrophage-based cell therapies represent a cutting-edge frontier in immunotherapy, offering distinct advantages over conventional approaches like CAR-T. This review explores the potential of macrophages to orchestrate both innate and adaptive immune responses, enhancing the body's ability to combat diseases locally and systemically. Dubbed a "Smart Cell Therapy," macrophages can initiate and coordinate complex immunological cascades, leveraging multiple immune system components while also performing effector functions.

Immune cell effector therapies, including chimeric antigen receptor (CAR)-T cells, T-cell receptor (TCR) T cells, natural killer (NK) cells, and macrophage-based therapies, represent a transformative approach to cancer treatment, harnessing the immune system to target and eradicate malignant cells. CAR-T cell therapy, the most established among these, involves engineering T cells to express CARs specific to cancer cell antigens, showing remarkable efficacy in hematologic malignancies like leukemias, B-cell lymphomas, and multiple myeloma. Similarly, TCR-modified therapies, which reprogram T cells to recognize intracellular tumor antigens presented by major histocompatibility complex (MHC) molecules, offer promise for a range of solid tumors.
