Intact dystrophin protein of type I fibers. Serial sections reveal normal dystrophin and laminin sarcolemmal protein expression in type I fibers displaying loss of NOS activity and reduced nNOS protein. NOS activity in black, dystrophin in white, laminin in blue, MHC-I in green, and nNOS in red. * marks identical fibers on serial sections. Scale bar: 100 μm.
