Alzheimer's Impact on Olfactory Cells' COVID-19 Response

A study conducted by researchers at the University of Eastern Finland has revealed how Alzheimer's Disease (AD) affects COVID-19 outcomes through changes in olfactory mucosal cells. While initial infection rates were similar between healthy individuals and those with AD, the latter showed altered gene activities post-infection, indicating heightened oxidative stress and changes in immune responses. This study provides crucial insights into the interplay between COVID-19 and AD, particularly through the olfactory system, and suggests that individuals with AD may face potentially more severe COVID-19 outcomes due to pre-existing inflammation in the olfactory mucosa.

The Hidden Dangers of Traffic Pollution on Our Sense of Smell

A study conducted by the University of Eastern Finland reveals that exposure to ultrafine particles from traffic emissions can significantly alter gene expression in human olfactory mucosa cells. The study found that both renewable and fossil diesel emissions disrupt various cellular functions, but renewable diesel, especially when combined with cleaner engine technology, causes fewer adverse effects. These findings highlight the potential pathway for environmental pollutants to impact the brain through the olfactory system, emphasizing the need for monitoring and regulating these emissions.
