Researchers led by Paul Coleman argue that all these alterations could be attributable to a single cause: the so-called stress granules, RNA and protein agglomerations that are temporarily formed in response to unleashed cell stress, such as, by genetic mutations, inflammation, exposure to pesticides, viruses and air pollution. These granules pause non-essential processes while the cell recovers, And they dissolve once the stress attenuates. In Alzheimer’s disease, however, granules persist abnormally and become chronic, ending up trapping vital molecules and hindering their movements to and from the cell nucleus. This transport blockage disrupts the production of essential proteins and alters the molecular switches that control the activity of over a thousand genes, causing a cascade of various clinical manifestations of Alzheimer’s.
these changes occur very early, Even before the appearance of the typical signs of the disease such as the amyloid plates or tangles of Tau. By identifying and addressing the formation of pathological stress granules in the initial phases,therefore,one could significantly arise or delay the onset of symptoms.

editor: Today, we have a groundbreaking interview wiht researchers led by Paul Coleman, focusing on their recent findings about the role of stress granules in Alzheimer’s Disease. Their work could dramatically impact our understanding and approach to this debilitating condition.
Editor: Can you tell us more about these stress granules and their normal function in cells?
Paul Coleman: Stress granules are temporary agglomerations of RNA and proteins that form in response to cellular stress. They play a crucial role in pausing non-essential processes while the cell recovers from stressors like genetic mutations, inflammation, exposure to pesticides, viruses, and air pollution. Once the stress attenuates, these granules dissolve, allowing the cell to resume normal function [[1](https://www.sciencedirect.com/science/article/pii/S2405844024172970)]
Editor: How are these stress granules implicated in alzheimer’s disease?
Paul Coleman: In Alzheimer’s disease, stress granules persist abnormally and become chronic. This persistence traps vital molecules and hinders their movements to and from the cell nucleus. This transport blockage disrupts the production of essential proteins and alters the molecular switches that control the activity of over a thousand genes. As a result, it triggers a cascade of various clinical manifestations associated with Alzheimer’s [[1](https://www.sciencedirect.com/science/article/pii/S2405844024172970)]
Editor: When do these changes begin in the disease progression?
Paul Coleman: These changes occur very early, even before the appearance of the typical signs of the disease such as the amyloid plaques or tangles of Tau. By identifying and addressing the formation of pathological stress granules in the initial phases, one could significantly delay or even prevent the onset of symptoms.This early intervention could make a significant difference in managing alzheimer’s [[1](https://www.sciencedirect.com/science/article/pii/S2405844024172970)]
Editor: What implications do these findings have for future research and treatment?
Paul Coleman: Our findings suggest that targeting the formation and persistence of pathological stress granules could be a novel therapeutic approach.By addressing these granules in the early stages, we might potentially be able to delay or prevent the onset of Alzheimer’s symptoms, offering new hope for patients and their families [[1](https://www.sciencedirect.com/science/article/pii/S2405844024172970)]
Editor: Thank you, Paul Coleman. Your insights are incredibly valuable and provide a new perspective on understanding and possibly treating Alzheimer’s disease.
Paul Coleman: Thank you for having me. It’s an exciting time for Alzheimer’s research, and we hope our findings contribute significantly to future advancements in the field.
