CMA1 and lysosomal lipid storage disorder: In another study, performed on 44 sections of aortas collected from autopsies using anti-tryptase and anti-chymase antibodies, the following results were obtained: (1) chymase+ MCs were more abundant in the non-elderly group, (2) a positive correlation between the number of chymase+ MCs and percentage of collagen (rS = 0.115, P = 0.006) and also between number of tryptase+ MCs and percentage of collagen (rS = 0.111, P = 0.008) was found at the site, and (3) a positive correlation between lipidosis and the number of tryptase+ MCs (rS = 0.117; P = 0.004) was reported [23].
