Neurodegenerative diseases are characterized by the deposition of clumped proteins in the brain and progressive neuronal cell death. Although the causal link between protein aggregates and neurodegeneration is clear, it is still unclear in what way misfolded proteins trigger cell death. A team showed that misfolded prion proteins can inactivate the TDP-43 protein.

Pregnancy brings a rise in pancreatic beta cells -- the cells that produce insulin. Shortly after birth, these cells return to their normal levels. The mechanisms behind this process had remained a mystery. But now a research group has revealed that white blood cells called macrophages 'eat' these cells.

Decreasing pancreatic beta cell numbers -- the only cells that produce insulin -- is a leading cause of diabetes. In a promising development, a research group has revealed that stimulating autonomic vagal nerves connected to the pancreas can improve the function and also increase the number of pancreatic beta cells in mice.

Self-folding polymers containing gadolinium forming nanosized complexes could be the key to enhanced magnetic resonance imaging and next-generation drug delivery. Thanks to their small size, low toxicity, and good tumor accumulation and penetration, these complexes represent a leap forward in contrast agents for cancer diagnosis, as well as neutron capture radiotherapy.
