Communication between adipose tissue and the brain increases the risk of cognitive impairment in patients with insulin resistance through extracellular vesicles (EVs) containing microRNAs (miRNAs). Neurons could be damaged when these nucleotides reach the hippocampus guided by membrane proteins in prediabetic overweight people.

Collagen is the most abundant protein in the human body, which would seem to make it an unlikely source for an immunotherapy target. But it is where researchers from Immatics Biotechnologies GmbH and the University of Pennsylvania have found a target that was expressed on stromal cells in a number of different solid tumors, but very rare in normal tissues.
