Background: Ageing displays a low-grade pro-inflammatory profile in blood and brain. It has been documented proinflammatory cytokines accumulation leading to neuroinflammation during aging. Aged brains integrate pro inflammatory cytokines accumulation, active microglia and volumetric changes which correlates with defective cognitive performance and neurodegeneration.
Methods: Mice from 2-,12- and 20-months-old of age were submitted to different memory tests: Y-maze, Barnes maze, object location test and object location test. Afterwards, we performed structural MRI to evaluate macrostructural changes related to memory and learning regions. Following this, we also evaluated in peripheral blood and in brain tissue the presence of pro-inflammatory cytokines …
