Abstract
BACKGROUND
Alzheimer's disease (AD) is a progressive neurodegenerative disease characterized by progressive cognitive deterioration. All recent therapeutic strategies tend to inhibit the generation of the Aβ peptide. These approaches tend to mediate both α- and γ-secretases to undergo the non-amyloidogenic pathway. ADAM10 is the main α-secretase that cleaves APP, and it is regulated by the metabolic product of vitamin A (retinoic acid), which is being widely used recently in AD research as a target for treatment. Mesenchymal stem cells (MSCs) are also used recently as a promising regenerative therapy for AD.
OBJECTIVES
The present study aimed to: (1) study the effect of MSCs with/without acitretin on the regulation of Adam10 gene expression in AlCl3-induced AD rat model, (2) validate the hypothesis that AD is a time-dependent progressive disease that spreads spontaneously even after the stopping of exposure to AlCl3.
METHODS
The experimental work has been designed to include three successive phases; AlCl3 induction phase (I), AlCl3 withdrawal phase (W), and therapeutic phase (T). Forty-five male albino Wistar rats were randomly divided into 2 main groups: the control (C) group (15 rats) and AD group (30 rats). The therapeutic potential of MSCs with/without acitretin has been evaluated at behavioral, physiological, molecular, and histopathological levels Results: Among the three therapeutic groups, combined administration of both MSC and acitretin showed the best compensatory effects on most of the measured parameters.
CONCLUSION
The present study approved that AD is a time-dependent progressive disease and spreads spontaneously without more AlCl3 exposure.
