Abstract

Alzheimer's disease (AD) is a common neurodegenerative disorder that mainly affects the aged population and is characterized by the progressive loss of the hippocampal and cortical neurons, which results in memory and cognitive impairments. Trigonella foenum-graecum (fenugreek) has been reported to have hypoglycemic, hypocholesterolemic, hyperinsulinemic and anti-diabetic properties. Traditionally, it was used as a galactagogue and to treat anorexia, fever gastritis, gastric ulcers, and various nervous disorders. However, the neuroprotective effect of fenugreek seed powder against aluminum chloride (AlCl3) induced AD rats has not been analyzed. The result of the present study indicated that the chronic administration of AlCl3 induced significant learning and memory impairments, oxidative stress, and alterations in the protein immunocontent patterns of IDE and CDK5 (enzymes involved in the metabolism of tau and amyloid proteins), pTau, GFAP and Iba-1, IL-1β, IL-6, TNF-α, iNOS, NF-κB, COX-2, CDK5, BDNF, and STAT3. Our behavioral, biochemical, and molecular studies revealed that the co-administration of fenugreek seed powder significantly attenuated the AlCl3 induced memory deficits, amyloid and tau pathology, oxidative stress, and inflammation in AD rats could be due to the synergistic action of its active components.
