Desmin is an intermediate filament protein that is specifically localized in:
A) Astrocytes
B) Cardiac muscle
C) Lymphocytes
D) Macrophages
E) Simple cuboidal epithelial cells

Question

Quizplus · Accepted Answer

Desmin is specifically localized in cardiac muscle cells, where it provides structural support and helps to maintain the alignment of contractile elements. It is also expressed in smooth and some skeletal muscle cells. Astrocytes do express intermediate filament proteins, but they are not typically desmin. Lymphocytes, macrophages, and simple cuboidal epithelial cells do not typically express desmin.
