Keilhoz A, Pathak I, Smith CL, Osman KL, Smith L, Oti G, Golzy M, Mz L, Lever TE, Nichols NL (2024) Tongue exercise ameliorates structural and functional upper airway deficits in a rodent model of hypoglossal motor neuron loss. Front Neurol 15:1441529. doi: 10.3389/fneur.2024.1441529 PMID: 39296960
Objective: To investigate the effects of a strength endurance tongue exercise program on upper airway structure and function.
Summary: Results showed that sham exercise-treated CTB-SAP rats have evidence of upper airway restriction (i.e., reduced airflow) and structural changes present in the upper airway (i.e., airway compression) when compared to rats treated with CTB-SAP and exercise and control rats with/without tongue exercise, which were ameliorated with tongue exercise. Additionally, CTB-SAP treated, sham exercise rats have evidence of increased lipid expression in the tongue consistent with previously observed tongue hypertrophy when compared to CTB-SAP treated exercise rats or control rats with/without tongue exercise.
Usage: Intralingual injection of either unconjugated CTB+SAP (20 μg CTB+25 μg SAP) or conjugated CTB-SAP (25 μg of CTB conjugated to SAP).
