细胞穿膜肽介导生物大分子入胞机制研究进展

生物大分子药物与传统治疗方式相比作用靶点具有高度的专一性,成为21世纪药物研发中最具发展前景的领域之一,但由于细胞膜的天然屏障作用致使许多潜在的胞内药物靶标无法应用于新药研究。细胞穿膜肽(cell-penetrating peptides,CPP)是一类具有穿膜功能的小分子短肽,可高效携带核酸、蛋白质等生物大分子穿过细胞膜进入胞质发挥功能,在介导生物大分子药物入胞上有着高效、低毒等诸多优势,但仍存在效率低、靶向性差等问题。CPP携带货物分子入胞的方式可以根据是否依赖能量分为直接入胞和内吞。直接入胞依据孔隙形成的方式不同分为四种模型:桶板模型、超环面模型、地毯模型和反向胶团模型。内吞则根据受体的不同又分为巨胞饮、网格蛋白介导的内吞、小窝蛋白介导的内吞、硫酸乙酰肝素蛋白聚糖介导的内吞以及神经毡蛋白-1介导的内吞。CPP自身的类型、浓度、效应分子的物理化学性质以及分子大小都会影响CPP的入胞过程,进而决定CPP携带生物大分子入胞的途径。对CPP介导生物大分子的入胞机制进行综述,为研究更加高效、靶向性强的CPP提供依据,从而推动其在生物、医学领域的应用。国家自然科学基金(81501835)福建省自然科学基金(2017J05136)资助项

Observation and analysis of Marangoni convection induced by desorption in soap film

利用竖直流动皂膜装置,使用纹影光学方法观察了由于丙酮从皂液中解吸,在微米级厚度皂膜上出现的滚筒状MArAngOnI对流结构;通过建立皂膜传质数学模型及求解,分析了丙酮从皂膜解吸过程中浓度及表面张力的变化。结果表明:由于微米级的皂膜厚度,在皂膜平面法向方向皂膜内皂液丙酮浓度变化很小,但浓度梯度较大,对应的表面张力梯度较大,此较大表面张力梯度是丙酮从皂膜解吸过程中出现MArAngOnI对流的主要成因。By means of the falling soap film tunnel and the Schlieren optical method,the orderly roll Marangoni convection patterns along the surface of the falling soap film with 10-6 m order thickness were observed directly during the acetone desorption from the falling soap liquid.The acetone desorption model from the falling soap film was established and solved theoretically in order to analyze the variation of the concentration and the surface tension.The results show that the variation of the acetone concentration vertical to the falling direction within the thin film is very small,but the gradients of both the acetone concentration and surface tension are large.So the big tension gradient is the main reason for the occurrence of the Marangoni roll convection in acetone desorption from soap film.国家自然科学基金资助项目(20606027

五配位磷化合物与生物化学

综述了五配位磷化合物与生物化学的关系,发现当α-氨基酸的氨基接上磷酰基团以后,化学性质发生了许多奇特的现象,在室温下可发生自身活化现象而成肽、成酯、磷上酯交换及N→O磷酰基转位;丝氨酸和苏氨酸与核苷缀合以后,在弱碱性条件下能够对不同的碱基进行识别;磷酰化组氨酸和丝组二肽可以在中性条件下切割核酸、蛋白、酯.发现上述现象的发生都经历了一个五配位磷中间体,认为五配位磷中间体是决定它们活性的结构因素
