Chimeric proteins improve peripheral neuropathy in the mouse model of CMD 1A
While the expression of artificial binding proteins specifically in muscle tissue improves the dystrophic phenotype and compensates for LAMA2 deficiency in DMC 1A mouse models, it can also accentuate peripheral neuropathy and cause paralysis of the animal’s hind limbs. A study by researchers at the Biozentrum in Switzerland shows that inducing pantissular expression of two … [Read more]
