New Study Reveals Potential Alzheimer’s Treatment with Anti-Inflammatory Drugs
A recent study conducted at the University of Kentucky’s Sanders-Brown Center on Aging has shed new light on the potential use of anti-inflammatory drugs for the treatment of Alzheimer’s disease (AD). The study focused on a protein called p38, which has been a target for drug development in the field of neuroinflammatory dysfunction.
Researchers in the study used genetic techniques to halt the production of p38 in brain immune cells, specifically microglia, which are crucial in AD pathology. They then observed the effects of this inhibition in an early-stage mouse model of AD to analyze its impact on amyloid plaque formation, a major component of AD pathology.
While the amyloid plaques themselves were not affected, the researchers noticed a decrease in the concentration of microglia around these plaques. This suggests that suppressing microglial p38 may alter their interactions with AD pathology elements. This finding opens up new possibilities for the development of anti-inflammatory drugs that specifically target p38 to treat Alzheimer’s disease.
Some classes of anti-inflammatory drugs already include p38 inhibitors, which have shown promising results in recent human clinical trials. However, the optimal timing for administering these inhibitors during the disease process and the potential long-term effects of p38 suppression are still not fully understood.
According to Linda Van Eldik, Ph.D., the director of the University of Kentucky’s Sanders-Brown Center on Aging, early inhibition of p38 may be able to change interactions between brain immune cells and AD pathology, potentially altering the progression of the disease. The study also found that long-term suppression of p38 did not lead to noticeable adverse effects.
The findings of this study provide valuable insights into the mechanisms underlying the potential use of anti-inflammatory drugs for treating Alzheimer’s disease. Further research is needed to determine the most effective timing and dosage of p38 inhibitors, as well as to investigate their effects on different stages of the disease.

This study adds to the growing body of research exploring the relationship between inflammation and neurodegenerative diseases. By targeting specific proteins involved in the immune response, researchers hope to develop more effective treatments for Alzheimer’s disease and other conditions with neuroinflammatory dysfunction.
The findings of this study have been published in the journal PLOS ONE and provide a promising direction for future research and drug development in the field of Alzheimer’s disease treatment.
