Camel milk extracellular vesicles/exosomes: a fascinating frontier in isolation and therapeutic potential.

Camel milk has a unique composition that sets it apart from other types of animal milk, which has captured the interest of medical and scientific communities. Extracellular vesicles (EVs) mainly contain exosomes (Exos, 30-200 nm) and microvesicles (MVs, 200-1000 nm). Camel milk EVs, particularly Exos, which we named EVs/Exos, have arisen as a fascinating area of scientific inquiry, holding enormous potential for the future of biomedicine due to their anticancer, antibacterial, antidiabetic nephropathy, and immunostimulatory impacts. Camel milk EVs/Exos affect the antioxidant status and oxidative stress differently depending on the target cells. They boosted ROS in cancer cells but improved the antioxidant state in healthy cells. Camel milk EVs/Exos have distinct exosomal lactoferrin and kappa casein mRNAs, which could be responsible for their anticancer and immunomodulatory effects. Due to the high fat content of milk, there is a lack of established protocols for the precise isolation of EVs/Exos from milk, despite the increasing interest in this area of study. This review highlighted the techniques employed for milk EV/Exo isolation and characterization, acknowledging the challenges faced by researchers and the latest advancements in overcoming these hurdles. This review also detailed the potential of camel milk EVs/Exos in therapeutic applications. This comprehensive analysis positions camel milk EVs/Exos at the forefront of scientific inquiry, paving the way for groundbreaking discoveries in the years to come.
