Protein therapy for Unverricht-Lundborg disease using cystatin B transduction by TAT-PTD

TAT-PTD-CSTB does not penetrate the cells despite initial evidence of time and concentration-dependent transduction. Therefore, it cannot be used as a form of replacement of the intracytoplasmic protein missing in UL. Importantly, we discuss precautions to avoid false-positive results when working with TAT-PTD for protein therapy of neurological diseases.
