Extracellular vesicles (EVs) mediate the cross-talk between cancer cells and the cells of the surrounding Tumour Microenvironment (TME). Professional killer cells include Natural Killer (NK) cells and CD8+ Cytotoxic T-lymphocytes (CTLs), which represent some of the most effective immune defense mechanisms against cancer cells. Recent evidence supports the role of EVs released by NK cells and CTLs in killing cancer cells, paving the road to a possible therapeutic role for such EVs. This review article provides the state-of-the-art knowledge on the role of NK-and CTLderived EVs as anticancer agents, focusing on the different functions of different subtypes of EVs. We also reviewed the current knowledge on the effects of cancer-derived EVs on NK cells and CTLs, identifying areas for future investigation in the emerging new field of EV-mediated immunotherapy of cancer.
The study of variations in human neurodevelopment and cognition is limited by the availability of experimental models. While animal models only partially recapitulate the human brain development, genetics, and heterogeneity, human-induced pluripotent stem cells can provide an attractive experimental alternative. However, cellular reprogramming and further differentiation techniques are costly and time-consuming and therefore, studies using this approach are often limited to a small number of samples. In this study, we describe a rapid and cost-effective method to reprogram somatic cells and the direct generation of cortical organoids in a 96-well format. Our data are a proof-of-principle that a large cohort of samples can be generated for experimental assessment of the human neural development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
