rly by the inward budding of endocytic compartment membranes [15,16]. These EVs play a significant part in several biological responses, including cell communication, apoptosis, and immuneresponses [17]. Recently, they’ve been offered vital attention as a result of the growing ability to be isolated from blood, urine, saliva, and breast milk using numerous analytical procedures [18], and for their relevance within the quantification and identification of biomarkers in cancer, neurogenerative disease, cardiovascular disease, and infection [193]. Even though svEVs had been first observed in 1973 [24], only four current studies have shown evidence for snake venom extracellular vesicles and partial characterization [258]; nevertheless, their precise protein content, function, and mechanism/role in snake envenomation stay unknown. In our study, we examined C. atrox and C. o. helleri snake venom-derived extracellular vesicles. Each displayed a unique venom toxin composition in EVs. Interestingly, EVtrap enrichment revealed previously unidentified signaling, adaptor, transmembrane, and vesicle proteins.
