Activity of the c-Fos gene begins the increase on the ninth day of exposure to antidepressants. By day 14, mice showed behavioral changes associated with SSRI use. This may explain why suicide rates drop after nine days of treatment, and symptoms of depression improve after three weeks.
Researchers discovered a bacteria of the genus Bartonella releases a protein, which they dubbed BafA, which stimulates the production of new blood vessels that support bacterial lesions. Bartonella henselae causes cat scratch disease. The findings provide new insight into the mechanisms by which infectious bacteria can produce lesions.
The FGF signaling pathway is an important extracellular regulator in the fate of neural stem cells switching from neurons to astrocytes in the cerebral cortex.
Hepatitis C virus increases the expression of SOCS, dulling the normal immune system response to viral infections. This may explain why Hepatitis C 'hides' in the immune system, leading to a lack of diagnosis in those suffering the infection.
Researchers have identified 40 new genes they believe are related to aggressive behavior in both humans and mice. The findings deepen understanding of the genetic basis of aggressiveness.
NIH researchers have identified a set of genes they believe could explain why some people need more, or less, sleep that others. The findings could help to develop new treatments for a variety of sleep disorders from insomnia to narcolepsy.
A plasma membrane protein affects the generation of new neurons in the adult hippocampus, a new study reports.
A new study finds wine-derived human gut metabolites may have neuroprotective capabilities.
Researchers discover a decline in glucose levels in the brain that occurs during the early stages of MCI.
