          摘   要  酵母微囊是一种表面粗糙多孔、核心中空的天然药物递送载体,具有良好的安全性和高靶向性、高稳定性,在口服药物递
          送系统中具有极佳的应用前景。酵母细胞经过酸碱和有机溶剂处理、洗涤后可获得疏松多孔的酵母微囊,后者可借助静电相互作
          用、被动扩散、疏水作用等方式包载药物。酵母微囊表面主要由β-葡聚糖组成,可在胃肠环境中保持稳定,可被免疫细胞表面相关
          受体识别,从而激活免疫反应,并可在被摄取后随淋巴细胞的运动将所载药物运送至病变部位。酵母微囊安全性高,非常适合递
          送疫苗、抗炎药物及抗肿瘤药物,其不仅可实现上述药物的口服递送,而且能增强药物效果,提高药物的靶向性。今后可开展更多
          全身转运机制的相关研究或开发更加高效的联合给药系统,以充分发挥酵母微囊的临床价值。

          ABSTRACT    As  a  natural  drug  delivery  carrier  with  rough  and  porous  surface  and  hollow  core,  yeast  microcapsules  have  good
          safety,  high  targeting  and  high  stability,  and  have  excellent  application  prospects  in  oral  drug  delivery  systems. Yeast  cells  can  be
          treated  and  washed  with  acid-base  and  organic  solvents  to  obtain  loose  and  porous  yeast  microcapsules.  Yeast  microcapsules  can
          encapsulate  drugs  through  electrostatic  interactions,  passive  diffusion,  hydrophobic  interaction  and  other  methods.  The  surface  of
          yeast  microcapsules  is  mainly  composed  of  β-glucan,  which  can  maintain  stability  in  the  gastrointestinal  environment;  it  can  be
          recognized  by  the  surface-related  receptors  of  immune  cells,  thus  activating  the  immune  response,  and  can  be  transported  to  the
          lesion  site  with  the  movement  of  lymphocytes  after  being  ingested.  Yeast  microcapsules  are  safe  and  very  suitable  for  delivering
          vaccines, anti-inflammatory drugs, and anti-tumor drugs. They can not only achieve oral delivery of the aforementioned drugs, but
          also  enhance  drug  efficacy  and  improve  drug  targeting.  In  the  future,  more  research  on  systemic  transport  mechanisms  or  the
          development  of  more  efficient  combination  drug  delivery  systems  can  be  carried  out  to  fully  exhibit  the  clinical  value  of  yeast
          microcapsules.
