Neuronal circuits able to rewire on the fly to sharpen senses

Researchers from Carnegie Mellon and Pitt describe a mechanism called dynamic connectivity, where neuronal circuits are rewired in response to specific patterns of stimuli. This process allows for more keenly sensed stimuli, such as recognizing scents, by filtering out noise and enhancing contrast.

Survival shortened when ER/PR negative breast cancer spreads to the brain

Two studies from Mayo Clinic found that ER/PR negative breast cancers have the worst overall outcomes when spreading to the brain, resulting in shorter median survival times. Women with triple negative tumors and HER2+ tumors without estrogen or progesterone receptors have poor outcomes due to aggressive brain metastasis.

New approach for attacking lupus identified

Researchers have discovered two new targets for drugs aimed at controlling lupus by regulating the balance between inflammatory and antiviral effects of interferons. By blocking specific kinases in the calcium-signaling pathway, they were able to suppress STAT1 activation and preserve antiviral effects.

Drug combination shrinks breast cancer metastases in brain

A combination of lapatinib and capecitabine significantly shrinks brain metastases in patients with aggressive HER2-positive breast cancer, with 10 patients experiencing a 50% reduction. The study's findings offer new hope for treatment options for women with advanced breast cancer who develop brain metastases.
