Laboratory of Food and Environmental Hygiene, Joint Department of Veterinary Medicine, Gifu University, Gifu, Japan; Education and Research Center for Food Animal Health, Gifu University (GeFAH), Gifu, Japan; Joint Graduate School of Veterinary Sciences, Gifu University, Gifu, Japan. Electronic address:

Extracellular vesicles (EV), including exosomes or small EV (sEV) derived from biological fluids, such as milk, have garnered increasing interest in veterinary medicine because of their role in the pathophysiology and understanding of the disease status of the host. Bovine milk serves as a rich source of sEV, containing diverse cargoes of nucleic acids, proteins, and lipids, which play a critical role in intercellular communication and regulation of host status. Although it is more difficult to isolate and purify sEV from bovine milk than from human breast milk, challenges persist in enabling the enrichment and analysis of sEV populations, facilitating the elucidation of their functional roles and prognostic potential in cattle diseases.

Article Synopsis
  • Hibernating animals can significantly lower their body temperature without damaging their organs, potentially due to active hypometabolism.
  • Researchers studied the phosphorylation of Akt to see if metabolism decreases during artificial hypothermia in hamsters.
  • They found that while hypothermia through adenosine A1 receptor activation decreased Akt phosphorylation significantly, anesthesia-induced hypothermia showed only partial reduction without organ damage, indicating both methods allow for regulated metabolic reduction.
