"Uncovering the Role of Proteasomes in Sensory Signaling"

Researchers have discovered a new role for proteasomes in nerve cells, suggesting that these structures, traditionally known as the cell's waste processors, may act as signal messengers in sensory neurons, aiding in the differentiation between pain and itch sensations. By blocking proteasomes with specific inhibitors in mice, significant changes in sensory response were observed, highlighting the potential for proteasomes to be targeted for therapeutic interventions in sensory disorders. This study redefines our understanding of proteasome functions and opens new avenues for treating sensory disorders.

The Benefits of Cold for Aging and Disease Prevention

Cold temperatures activate a cellular mechanism that breaks down harmful protein aggregations responsible for various diseases associated with aging, according to a study by the University of Cologne. The research team used a non-vertebrate model organism and cultivated human cells, both carrying genes for two neurodegenerative diseases. Cold actively removed protein clumps, preventing protein aggregation that is pathological in both diseases. The scientists explored the impact of cold on the activity of proteasomes, a cellular mechanism that removes damaged proteins from cells. The research revealed that the proteasome activator PA28γ/PSME3 mitigated the deficits caused by aging in both the nematode and in the human cells.
