Research is being conducted on the role of mesenchymal stem cells in relation to astrocytes and their impact on synapse dysfunction in early Alzheimer's disease. The function of astrocytes in the brain is being explored, with some studies suggesting they may contribute to brain disorders. Mesenchymal stem cells are also being investigated for their potential in treating various diseases, including neurodegenerative diseases, through mechanisms such as modulating neuroinflammation and promoting tissue repair.
