Abstract
PURPOSE
Dystrophin and the dystrophin glycoprotein complex serve as a cytoskeletal integrator, critical for muscle membrane stability. The aim of the present study was to clarify the expression of dystrophin protein and mRNA in the skeletal muscle tissue during the muscle phase of trichinellosis in mice.
METHODS
Muscle tissue was collected from mice experimentally infected with Trichinella spiralis at days 0, 14 and 40 after infection. The expression of dystrophin in the muscle tissue was investigated by immunohistochemistry with antibodies against three different domains of the protein, and the expression levels of Dys mRNA by real-time PCR.
RESULTS
The presence of dystrophin protein was increased in the de-differentiating cytoplasm at the early stage of muscle infection and was persisting also in the mature Nurse cell harbouring the parasite. It was accompanied by significantly elevated expression of Dys mRNA at days 14 and 40 after infection.
CONCLUSION
Our findings indicate that dystrophin plays a role in regeneration of the muscle and in the Nurse cell formation and stability for security of the parasite survival.
