| Signaling molecule may help prevent Alzheimer's disease Posted: 14 Jul 2021 08:05 AM PDT The main driver of Alzheimer's disease is excessive inflammation in the brain that is triggered by cells called astrocytes and microglia in response to high levels of amyloid beta deposits and tau tangles. New research reveals that a subset of astrocytes releases a molecule called interleukin-3 that instructs microglia to adopt a protective response and clear away amyloid beta deposits and tau tangles. Interleukin-3 may hold promise as a new therapeutic intervention in Alzheimer's disease. |
| Fungi that live in the gut influence health and disease Posted: 14 Jul 2021 08:05 AM PDT Bacteria's role in gut health has received attention in recent years. But new research shows that fungi -- another microorganism that lives within us -- may be equally important in health and disease. Fungi thrive in the healthy gut, but when interactions with the immune system are off-balance, they cause intestinal damage that may contribute to gastrointestinal disease. Additional investigation demonstrate that vaccines could be developed as therapeutics to improve gut health. |
