Unraveling the physiological functions of exosome secretion by tumors

To understand the physiological functions of exosomes, we have recently used the inhibition of Rab27a, which prevents exosome release but also alters other secretion pathways. Our work demonstrates that the secretion of exosomes by some tumors in vivo can influence the immune microenvironment to promote tumor progression, but also that this phenomenon cannot be generalized to all tumors and all...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Rab35 drives exosome secretion

Rab35 drives exosome secretion T he GTPase Rab35 regulates the release of small vesi-cles called exosomes from the surface of glial cells, say Hsu et al. Exosomes are formed in the lumen of specialized endosomes called multivesicular bodies (MVBs), which fuse with the plasma membrane to secrete the vesicles extracellularly. The process was fi rst described as a way for differentiating reticuloc...
