Extracellular Vesicle Transportation and Uptake by Recipient Cells: A Critical Process to Regulate Human Diseases

Area of Science:

• Biomedical Sciences
• Cell Biology
• Molecular Medicine

Background:

• Extracellular vesicles (EVs) play a significant role in modulating various human diseases, including cancer, inflammation, and neurological disorders.
• EVs are present in most human body fluids, indicating their potential for targeted delivery to distant cells.
• While EV biogenesis and secretion are well-studied, their transport, target recognition, and cellular uptake mechanisms require further elucidation.

Purpose of the Study:

• To review the current understanding of extracellular vesicle (EV) uptake mechanisms.
• To discuss the specificities governing EV-cell interactions.
• To highlight the implications of EV uptake in human diseases for diagnostic and therapeutic applications.

Main Methods:

• Literature review of existing research on EV uptake.
• Analysis of studies investigating EV targeting and binding.
• Synthesis of data on cellular mechanisms of EV internalization.

Main Results:

• EV uptake mechanisms are diverse and cell-specific.
• Specific molecular interactions mediate EV binding and internalization.
• Understanding these mechanisms is crucial for harnessing EVs in disease contexts.

Conclusions:

• EV uptake mechanisms are critical determinants of their biological functions in disease.
• Targeted modulation of EV uptake pathways holds promise for novel therapeutic strategies.
• Further research into EV-cell interactions will advance their clinical applications.
