Conditions
Summary
This study examines how berry consumption influences the signaling and distribution of extracellular vesicles (EVs) in the human body. EVs are small bilipid-layered nanoparticles released by cells. EVs carry proteins, lipids, and genetic material, and play a key role in cell-to-cell communication. The composition of EVs reflects the state of their cells of origin, and EVs can affect other cells by delivering their biological contents. EVs offer significant potential for both diagnostics and new therapies. Recent research has shown that EVs can be found in blood, urine, sweat, and can even cross biological barriers such as the blood-brain barrier and placenta. Many living organisms, including mammalian cells, bacteria, and plants, release EVs. Berries such as cloudberries and lingonberries have demonstrated positive effects on gut microbiota and metabolism, supporting digestive and metabolic health. In this study, a nutritional intervention will be conducted to investigate the effects of berry consumption on extracellular vesicle signaling of human cells and the gut microbiota, as well as the biodistribution of berry-derived vesicles in the human body.
