Afterwards, this worsening induces the person incapable of doing even the most fundamental duties. Recent research have proven that Coenzyme-q10 (CoQ10), one of the endogenous fatty acids, suppresses phosphorylated Tau protein which is GM1-ganglioside-bound amyloid beta-protein (GM1-A beta), and inhibiting the formation of amyloid plaques in Alzheimer's disease. Unfortunately, CoQ10 is poorly absorbed due to its high molecular weight (863.34 g/mol) and high lipophilicity, and its bioavailability is quite low. Therefore, we developed the CoQ10-loaded, cholesterol-free liposomes to get across the limitations.Material and methods: Liposomes were developed by ether injection method, and physicochemical characterization of the liposomes were evaluated in terms of particle size, size distribution (PDI), zeta potential, encapsulation efficiency (% EE), and process recovery as well. Release study, DSC analysis, morphological analysis, and cytotoxicity assay were performed with optimized formulations.Results: The particle size, PDI, zeta potential, EE%, and process recovery of the formulations ranged from 343.8 to 167.9 nm; 0.269 to 0.431; (-56) to (-31.7); 18.15-93.48%; 74.63 to 99.62, respectively. According to cytotoxicity tests, liposomes have no significant toxic effect on cells while having decreased p-tau 181 and p-tau 231 proteins (p > 0.05). Conclusions: As a result, the novel cholesterol-free liposome formulation were proved that it might be candidate of including the therapeutical guideline for the future alzheimer's disease treatment with these substantial results.en10.1016/j.jddst.2023.104468info:eu-repo/semantics/closedAccessLiposomeCoenzyme Q10Cholesterole-FreeAlzheimerSH-SY-5YSoy LecithinEnhanced SolubilityOxidative StabilityElderly-PatientsDeliveryBrainBioavailabilityNanoparticlesMemoryFoodArticle84N/AWOS:0009902868000012-s2.0-85153521114Q1
