Exosomes in tumour immunity
In preclinical studies, dc-derived exosomes administered as prophylactic 9 or therapeutic 5 cancer vaccines demonstrated their value as potent immune-activating agents, often more so than did live dcs. Based on this premise, some phase i trials of dc-exosomes have been conducted, showing promising results in very testing clinical scenarios, such as advanced non-small-cell lung cancer 10. Why dc...
متن کاملThe Dichotomy of Tumor Exosomes (TEX) in Cancer Immunity: Is It All in the ConTEXt?
Exosomes are virus-sized nanoparticles (30-130 nm) formed intracellularly as intravesicular bodies/intralumenal vesicles within maturing endosomes ("multivesicular bodies", MVBs). If MVBs fuse with the cell's plasma membrane, the interior vesicles may be released extracellularly, and are termed "exosomes". The protein cargo of exosomes consists of cytosolic, membrane, and extracellular proteins...
متن کاملExosomes in the ascites of ovarian cancer patients: origin and effects on anti-tumor immunity.
This study was performed to identify the origin of the ascites-derived exosomes from patients with ovarian cancer and to observe the effect of exosomes on anti-tumor immunity. Exosomes were isolated from the ascites of patients with ovarian epithelial cancer by ultracentrifugation plus density gradient centrifugation. The origin of exosomes was identified by immunoelectronmicroscopy (IEM). The ...
متن کاملDendritic cell-derived exosomes stimulate stronger CD8+ CTL responses and antitumor immunity than tumor cell-derived exosomes.
Exosomes (EXO) derived from dendritic cells (DC) and tumor cells have been used to stimulate antitumor immune responses in animal models and in clinical trials. However, there has been no side-by-side comparison of the stimulatory efficiency of the antitumor immune responses induced by these two commonly used EXO vaccines. In this study, we selected to study the phenotype characteristics of EXO...
متن کاملTumor-derived exosomes
Intercellular communication is a key process in the development and progression of cancer. The dynamic and reciprocal interplays between the tumor and its microenvironment orchestrate events critical to the establishment of primary and metastatic niches and maintenance of a permissive environment at the tumor-stroma interface. Atay and colleagues found that gastrointestinal stromal tumor cells ...
