Life Extension Gene “Klotho” also extend your Cognition

by Avinash Singh

Enhanced CognitionAging is the primary risk factor for cognitive decline, an emerging health threat to aging societies worldwide. Whether anti-aging factors such as klotho can counteract cognitive decline is unknown. Scientists shows that a lifespan-extending variant of the human KLOTHO gene, KL-VS, is associated with enhanced cognition in heterozygous carriers. Because this allele increased klotho levels in serum and analyzed transgenic mice with systemic overexpression of klotho. Mice performed better than controls in multiple tests of learning and memory. Elevating klotho in mice also enhanced long-term potentiation, a form of synaptic plasticity, and enriched synaptic GluN2B, an N-methyl-D-aspartate receptor (NMDAR) subunit with key functions in learning and memory. Blockade of GluN2B abolished klotho-mediated effects. Surprisingly, klotho effects were evident also in young mice and did not correlate with age in humans, suggesting independence from the aging process. Augmenting klotho or its effects may enhance cognition and counteract cognitive deficits at different life stages.

The gene takes its name from the entity in Greek mythology called ‘Clotho’, who was one of the ‘fates’ who were supposed to control the thread of people’s lives.

If this research bears further fruit, the KLOTHO gene could change the fate of many people’s lives.
