一般描述

聚 （丙交酯-乙交酯）（PLGA）是一种可生物降解的聚合物，用于制备聚合物微球。这些聚合物在体内通过其酯骨架水解为无毒产物而降解，这些无毒产物可由肾脏排出，或通过生物化学途径分解为CO2 和水。PLGA微球被广泛应用于包裹药物分子，并可用作长效缓释药物制剂。

应用

聚 （丙交酯-乙交酯）（PLGA）可用于制造缓释药物递送体系，例如，它可用于包裹抗炎亲脂药物阿托伐他汀。

Current development efforts of subunit vaccines against Toxoplasma gondii, the etiological agent of toxoplasmosis, have been focused mainly on tachyzoite surface antigen 1 (SAG1). Since microparticles made from poly (lactide-co-glycolide) (PLG) polymers have been developed as safe, potent adjuvants or

Aberrant T-cell activation underlies many autoimmune disorders, yet most attempts to induce T-cell tolerance have failed. Building on previous strategies for tolerance induction that exploited natural mechanisms for clearing apoptotic debris, we show that antigen-decorated microparticles (500-nm diameter) induce long-term
