INNOVATION
CalcrCre mice have the endogenous calcitonin receptor (Calcr) promoter/enhancer sequences directing expression of Cre recombinase. These mice are a Cre-lox tool allowing Cre recombination in Calcr-expressing cells/tissues (including neurons of the nucleus of the solitary tract, hypothalamus, and lateral reticular nucleus) and may be useful for studying feeding behavior, obesity, and metabolism.
