Phenotype Image Detail
Caption A: Four month old Soat1tm1Far/Soat1tm1Far Apoetm1Unc/Apoetm1Unc (ACAT1-/- ApoE-/-) fed a chow diet. Note the diffuse hair loss and excoriations due to pruritic skin lesions. B-D: Hematoxylin and eosin stained sections of skin from 4 month old, chow fed Apoetm1Unc/Apoetm1Unc (B, x40), and double homozygous (C, x40; D, x100) mice. Marked thickening of skin was observed in double homozygous mice (C), with an intense inflammatory reaction disrupting the subcutaneous fat layer and muscularis carnosus. Severe fibrosis was present in the deeper layers of the skin. Higher magnification of the reticular dermis (D) revealed numerous cholesterol clefts and a pleomorphic inflammatory infiltrate that included multinucleated giant cells, neutrophils, mononuclear cells and plasma cells. E: Skin cholesterol content of 4 month old chow fed mice (n=2 in each group). F: Hematoxylin and eosin stained section of brain from double homozygous mouse fed a Western diet for 3 months. Note the free cholesterol crystal deposits and inflammatory infiltrate near the choroid plexus.
