Individual stress susceptibility and glucose metabolism are linked to brain function
October 2018  |  Science News
Researchers have now discovered that stress-induced mental disturbances in mice are directly linked to abnormal glucose metabolism. Normalizing the stress-induced alterations in glucose levels, using the anti-diabetic drug empagliflozin, restored spatial memory as well as long-term glucose metabolism.

Cancer Can Change Neutrophils' Behavior Influencing Them to Support Tumor Growth
October 2018  |  Science News
Scientists say tumors recapitulated gene-expression and immune-infiltrate features of human squamous NSCLC; such features included enrichment of tumor-associated neutrophils (TANs) and decreased expression of NKX2-1, a transcriptional regulator that specifies alveolar cell fate.

Many cases of dementia may arise from non-inherited DNA 'spelling mistakes'
October 2018  |  Science News
Only a small proportion of cases of dementia are thought to be inherited -- the cause of the vast majority is unknown. Now a team of scientists believe they may have found an explanation: spontaneous errors in our DNA that arise as cells divide and reproduce.

Novel Parkinson’s Therapies Possible with New Mouse Model
October 2018  |  Science News
The new tetramer-abrogating mouse displayed key PD-like changes, including age-dependent αS aggregation in altered neurons and distinctive abnormal movements. These changes were all derived from preventing normal αS tetramer formation. These findings strongly suggest that tetramers are required for the normal state of αS in the brain.
