Extracellular vesicles (EVs): Introduction, Structure, Types, Isolation, Applications
Introduction to Extracellular Vesicles (EVs): Extracellular vesicles (EVs) are lipid bilayer membrane bound structures in extracellular fluids, which are secreted by all types of cells (either in normal or pathogenic conditions). They are naturally released from the cell that are delimited by a lipid bilayer and cannot replicate. EVs are complex signals which can target

Chagas Disease (American Trypanosomiasis): Epidemiology, Morphological Forms, Life Cycle, Pathogenesis, and Laboratory Diagnosis
Introduction to Chagas Disease (American Trypanosomiasis): Morphological forms of Trypanosoma cruzi: Amastigote Amastigote is small, round, cytoplasmic in shape and is found in the cytoplasm of mammalian host cells. Binary fission separates the flagellum, which is either short or invisible. Epimastigote The epimastigote has an elongated shape and a noticeable flagellum. It is present in
