Insights In Cardiovascular Therapeutics 2022

This Research Topic is part of the Insights in Frontiers in Cardiovascular Medicine series. Following the success of the inaugural series, Frontiers has organized a series of Research Topics to highlight the latest advancements in research across the field of cardiovascular medicine, with articles from the members of our accomplished Editorial Boards. This editorial initiative of particular relevance, led by Professor Masanori Aikawa, Specialty Chief Editor of the Atherosclerosis and Vascular Medicine section, is focused on new insights, novel developments, current challenges, latest discoveries, recent advances, and future perspectives in the field of atherosclerosis.

Cells of the myeloid lineage display diverse roles and functions both in tissue homeostatic conditions and during the development of liver diseases. Hepatic myeloid cells such asKupffer cells exert immune surveillance while maintaining immune tolerance. This helps to prevent excessive immune stimulation upon encounter with gut-derived antigens from food and commensal microbes, or rapidly identifying and eliminating pathogens. Myeloid cells also exhibit a dual role by contributing to both the initiation and progression of liver diseases. During liver inflammation, myeloid cells secrete cytokines and chemokines that promote chemotaxis and tissue damage. Further down the process they can undergo reprogramming into pro-resolving, anti-inflammatory cells. In extremis, these can lead to loss of liver function and development of fibrosis and cirrhosis. Liver myeloid cells can also dictate the progress of hepatic malignancy by either promoting the infiltration and activation or suppressing the activities of effector and/or cytotoxic T cells.
