Function

While their function has not yet been studied in great detail, it has been speculated that due to the morphological similarity of paramural bodies to the exosomes produced by mammalian cells, they may perform similar functions such as

membrane vesicle trafficking Membrane vesicle trafficking in eukaryotic animal cells involves movement of biochemical signal molecules from synthesis-and-packaging locations in the Golgi body to specific release locations on the inside of the plasma membrane of the secretory c ...

between cells. Current evidence suggests that, like exosomes, paramural bodies are derived from multivesicular bodies.
