Female internal mammary artery (IMA) hypersensitivity is independent of serotonin_2A and serotonin_2B receptor activity. A and B, Representative Western blot of serotonin_2A and serotonin_2B receptors, respectively, in the phosphorylated and unphosphorylated state (n=5 women, and n=6 men). C and D, Cumulative data of the rate of phosphorylated to total serotonin_2A and serotonin_2B receptors, respectively (n=5 women, and n=6 men). E and F, Total serotonin_2A and serotonin_2B receptor abundance, respectively, in male and female IMAs (n=5 women, and n=6 men). 0P indicates unphosphorylated receptor; 1P, phosphorylated receptor.
