•Retinol Binding Protein transports retinol and
thyroxine
•Produced by the liver, choroid plexus and adipose
tissue
•RBP4 is produced by adipocytes and is the main carrier protein for retinol in serum
•Elevated RBP4 is associated with abdominal obesity, raised TG levels, decreased HDL levels and systolic hypertension
•Serum RBP4 correlates with insulin resistance in obese and pre-diabetic subjects
•Serum RBP4 and serum retinol levels are moderately correlated
