<i>Ex vivo</i> evaluation of the effects of a white grape juice extract on lymphocytic mitochondrial functions Giuseppa Visalli Nadia Ferlazzo Alessio Facciolà Isa Picerno Michele Navarra Angela Di Pietro 10.6084/m9.figshare.7195379.v1 https://tandf.figshare.com/articles/journal_contribution/_i_Ex_vivo_i_evaluation_of_the_effects_of_a_white_grape_juice_extract_on_lymphocytic_mitochondrial_functions/7195379 <p>The physio-pathological role of mitochondria in aging and age-related diseases has stimulated the search for compounds able to promote mitochondrial functionality. Our study was designed to evaluate the effect of a white grape juice extract (WGJe) on mitochondrial activity, in an <i>ex vivo</i> experimental model consisting of activated lymphocytes obtained from a younger age group and an older age group of subjects. WGJe steadily decreased the lymphocytic mitochondrial mass in the older subjects, without a relevant effect in their younger counterpart, and significantly enhanced Δψm in both groups investigated. Finally, WGJe reduced the endogenous mitochondrial production of H<sub>2</sub>O<sub>2</sub> in all subjects. The results support the potential use of WGJe to improve mitochondrial functionality, thus maintaining human health and slowing down aging.</p> <p></p> 2018-10-11 12:45:08 Grape juice mitochondrial function lymphocytes aging resveratrol
