Transplantation of human dental pulp stem cells compensates for striatal atrophy and modulates neuro-inflammation in 3-nitropropionic acid rat model of Huntington's disease.

Stem cell-based therapy has recently offered a promising alternative for the remedy of neurodegenerative disorders like Huntington's disease (HD). Herein, we investigated the potential ameliorative effects of implantation of dental pulp stem cells (DPSCs) in 3-nitropropionic acid (3-NP) rat models of HD. In this regard, human DPSCs were isolated, culture-expanded and implanted in rats lesioned with 3-NP.

Expression of spinal cord GABA transporter 1 in morphine-tolerant male Wistar rats.

Chronic morphine exposure produces morphine tolerance. One of the mechanisms of morphine tolerance involves γ-aminobutric acid (GABA), whose level is regulated by GABA transporter 1 (GAT-1). The aim of this study was to investigate the expression of GAT-1 in the spinal cord during morphine treatment.
