Enhanced Insulin Sensitivity by Adipose Tissue Browning Alters Islet Morphology and Hormone Secretion in Response to Autonomic Nervous Activation in Female Mice.
Insulin resistance results in compensatory increase in insulin secretion to maintain normoglycemia. Conversely, high insulin sensitivity results in reduced insulin secretion to prevent hypoglycemia. The mechanisms for this inverse adaptation are not well understood. We utilized highly insulin sensitive mice, due to adipocyte specific overexpression of the FOXC2 transcription factor, to study mecha
