Summary:

- Researchers have discovered a protective protein called mesencephalic astrocyte-derived neurotrophic factor (MANF) that plays a key role in cellular health and longevity.
- MANF helps maintain the proper function of the endoplasmic reticulum (ER), a critical organelle within cells that is responsible for protein folding and processing.
- By understanding how MANF protects cells, scientists hope to develop new therapies to combat aging and age-related diseases like Parkinson's, Alzheimer's, and heart disease.
