New pretreatment method boosts islet transplant survival in diabetes

A pretreatment step could help transplanted pancreatic islets survive longer in patients with type 1 diabetes, according to a new preclinical study from Weill Cornell Medicine investigators. One combination of small molecules extended the cells' lives in female mice, and adding two molecules to the mixture boosted cell survival in male mice.

Monoamine neurotransmitters emerge as architects of brain physiology

A collaborative effort between Mount Sinai and Memorial Sloan Kettering Cancer Center has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of these monoamines to histone proteins, the core DNA-packaging proteins of our cells.
