Anxio-depressive phenotype and impaired memory in mice with a conditional knockout of brain-derived neurotrophic factor in endothelial cells.

The present study investigated the role of endothelial brain-derived neurotrophic factor (BDNF) in cognition. Male adult mice with a selective knockout of BDNF in endothelial cells () and their wild-type (WT) littermates were subjected to tests for detection of anxiety- and depression-like behaviors and impaired recognition memory. Neuronal activity and synaptogenesis were assessed from hippocampal levels of c-fos and synaptophysin, respectively, and cerebral capillary density from forebrain levels of CD31.

Cerebral Benefits Induced by Electrical Muscle Stimulation: Evidence from a Human and Rat Study.

Physical exercise (EX) is well established for its positive impact on brain health. However, conventional EX may not be feasible for certain individuals. In this regard, this study explores electromyostimulation (EMS) as a potential alternative for enhancing cognitive function.

Molecular mechanisms underlying physical exercise-induced brain BDNF overproduction.

Accumulating evidence supports that physical exercise (EX) is the most effective non-pharmacological strategy to improve brain health. EX prevents cognitive decline associated with age and decreases the risk of developing neurodegenerative diseases and psychiatric disorders. These positive effects of EX can be attributed to an increase in neurogenesis and neuroplastic processes, leading to learning and memory improvement.
