Regarding the immunogenic cell counts, a significant negative correlation wasfound between arterial S100β+ cell counts and degree of elastic fiberfragmentation/loss (r=-0.4016; P=0.0038), decreased cellularpreservation in HE (r=-0.5212; P=0.0001), and degrees ofoverall structural degeneration (r=-0.4063; P=0.0455) andoverall cellular preservation as grouped variables (r=-0.5811;P=0.0004). The gene discussed is S100B; the disease is hereditary elliptocytosis.
