在胰腺癌的临床前模型中评估工程外体的治疗疗效.

主要方法:

通过CD9修饰,工程外体 (ExoSmart) 通过CD9修饰共同显示RGD和CD47p110-130.
评估了ExoSmart在PDAC细胞上与αvβ3的结合以及细胞吸收在体外和体内.
评估了ExoSmart与巨细胞 (SIRPα) 的相互作用,以抑制细胞和减少MPS清除.

主要成果:

ExoSmart表现出对PDAC细胞的增强结合和细胞吸收的增加.
工程外体显示肝脏和脏的清除减少,这是由于抑制了巨细胞化.
在用ExoSmart治疗的PDAC模型中观察到化学治疗效率的增加.

Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Overview of Exosomes

Overview of Exosomes

Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from the...
