Abstract: Immunomodulatory mechanisms are indispensable and key factors in maintaining the balance
of the environment in humans. When the immune function of the immune system is impaired,
autoimmune diseases occur. Excessive body fatigue, natural aging of the human body, malnutrition,
genetic factors and other reasons cause low immune function, due to which the body is prone to being
infected by bacteria or cancer. Clinically, the existing therapeutic drugs still have problems such
as high toxicity, long treatment cycle, drug resistance and high price, so we still need to explore and
develop a high efficiency and low toxicity drug. Poly(lactic-co-glycolic acid) (PLGA) refers to a nontoxic
polymer compound that exhibits excellent biocompatibility. Traditional Chinese medicine
(TCM) monomers come from natural plants, and have the characteristics of high efficiency and low
toxicity. Applying PLGA to TCM monomers can make up for the defects of traditional dosage forms,
improve bioavailability, reduce the frequency and dosage of drug use, and reduce toxicity and side
effects, thus having the characteristics of sustained release and targeting. Accordingly, PLGA nanoparticles
loaded with TCM monomers have been the focus of development. The previous research on
drug loading advantages, preparation methods, and immune regulation of TCM PLGA nanoparticles
is summarized in the following sections.
