Regulatory T Cells: A New Target of Chinese Medicine in Treatment of Atherosclerosis.

ABSTRACT

Inflammation and immune disorders are integral to the occurrence and progression of atherosclerosis (AS). With the role of regulatory T cells (Tregs) in immune regulation attracting attention, it has been widely accepted that Treg decrease and dysfunction are involved in AS pathogenesis. Chinese medicine (CM) has the advantages of being dual-directional, multi-targeted, and having minimal side effects in immune regulation. The anti-atherosclerosis effects of CM via Treg modulation have been revealed in clinical and animal studies. Therefore, this article reviews existing research on Tregs, the relationship between Tregs and AS, and the progress of CM for treating and prevention of atherosclerotic cardio-cerebrovascular diseases by regulating Tregs. Although the underlying mechanisms remain to be elucidated, CM treatment targeting Treg cells might provide a promising and novel future approach for prevention and treatment of AS.
