Exosome uptake through clathrin-mediated endocytosis and macropinocytosis
and mediating miR-21 delivery.
The first mechanism is through uptaking the protein from dying neuron through macropinocytosis
. The second mechanism is through uptaking the protein through exosomes of neighboring cells.

and uptake of apoptotic cells," Journal of Experimental Medicine, vol.
During viral entry, the MLD and glycan cap facilitate viral adhesion to host cells, leading to macropinocytosis
The formation of actin filaments manifests in visible cup-shaped ruffles (waves) on the surface and throughout the cell, a behavior that is also known as macropinocytosis
, whereby cells produce vesicles that are absorbed into the cell.
Among the possible mechanisms of uptake, macropinocytosis
has also been explored .

of Flaviviridae  was used.
Adenovirus triggers macropinocytosis
and endosomal leakage together with its clathrin-mediated uptake.
Vaccinia virus uses macropinocytosis
and apoptotic mimicry to enter host cells.
