Pro-inflammatory CD11c+CD206+ adipose tissue macrophages are associated with insulin resistance in human obesity.

abstract：:Direct methods for measuring the secretion rate of insulin are too cumbersome for clinical application. Since C-peptide is secreted in an equimolar ratio with insulin and is excreted into the urine, measuring the urinary excretion rate of C-peptide (U-C) could serve as an indicator of its secretion rate (SR-C) if its ...
