Exosomes are nanosized membrane microvesicles (30⁻100 nm) that have the capability to communicate intercellularly and transport cell components (i.e., miRNA, mRNA, proteins and DNA). Exosomes are found in nearly every cell type (i.e., mast cells, dendritic, tumor, and macrophages). There ...

Discovery explains how Leishmania parasite boosts its infection A team of international scientists led by Dr. Martin Olivier from the Research Institute of the McGill University Health Centre (RI-MUHC) uncovered an important mechanism behind Leishmania, a deadly parasitic disease transmitted ...

Leishmania use exosomes to communicate with their mammalian hosts and these secreted vesicles appear to contribute to pathogenesis by delivering protein virulence factors to macrophages. In other eukaryotes, exosomes were found to carry RNA cargo, such as mRNAs and small ...
