The strong relationship between Alzheimer's Disease (AD) and diabetes mellitus (DM) is described by the term "type 3 diabetes". Canagliflozin (CAN), a sodium-glucose co-transporter 2 inhibitor (SGLT2i), is an antidiabetic agent under investigation as a potential new treatment for AD due to its acetylcholinesterase (AChE) inhibitory properties. We aimed to examine the effect of CAN on the efficacy of the anti-acetylcholinesterase, rivastigmine (RIV), against aluminum chloride (AlCl Show less

This study evaluated the neuroprotective potential of a combination therapy using liraglutide (LIRA), an antidiabetic agent, and rivastigmine (RIVA), a standard treatment for Alzheimer's disease (AD), in a rat model of aluminum chloride (AlCl₃)-induced AD. Male rats were divided into five groups: control, AD (AlCl₃,75 mg/kg for 60 days), RIVA-treated (1 mg/kg daily for 6 weeks), LIRA-treated (300 µg/kg daily for 6 weeks), and combination-treated (LIRA + RIVA). Cognitive function was assessed behaviorally, and hippocampal biomarkers related to AD-such as microtubule-associated protein Tau (MAPt), Beta-Site Amyloid Precursor Protein Cleaving Enzyme 1 (BACE1), Sequestosome 1 (SQSTM1/p62), and acetylcholinesterase (AChE) activity-were evaluated. Histopathological changes, immunohistochemistry, and transmission electron microscopy were also assessed. The levels of MAPt, BACE1, SQSTM1/p62, and AChE in the LIRA + RIVA group were 11.32 ± 0.467 ng/mL, 1069 ± 80.1 pg/mL, 408.7 ± 19.41 pg/mL, and 0.805 ± 0.342 µmol of acetylthiocholine iodide hydrolyzed/min/g of tissue, respectively. These levels were significant (p < 0.01) when compared with the AlCl Show less
