In der Haut wird BDNF von Keratinozyten und Fibroblasten exprimiert und könnte an Wundheilung, Kollagensynthese und antioxidativen Prozessen beteiligt sein. Tierversuche und In-vitro-Studien deuten auf einen möglichen anti-aging Effekt hin, indem es die Fibroblastenaktivität fördert und oxidativen Stress reduziert. Allerdings fehlen robuste Humanstudien, die einen direkten Zusammenhang zwischen BDNF-Genvarianten (z. B. Val66Met) und Hautalterung belegen. Die Evidenz ist überwiegend mechanistisch. DNA-Tests, die BDNF-Varianten mit Hautalterung verknüpfen, sind derzeit nicht klinisch handlungsrelevant. Faktoren wie UV-Schutz, Ernährung und Schlaf haben einen weitaus größeren Einfluss. Fazit: Es gibt interessante Hinweise, aber keine gesicherten Fakten. Verbraucher sollten solche Testergebnisse nicht als Grundlage für Anti-Aging-Maßnahmen nutzen.","area":"gesundheit","canonical_id":"gesundheit:canonical-92fe525d0f16abf315580c3b","id":"public-c85234dd87f7749c8b0793b3","kind":"qa","language":"de","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs Facts: BDNF und skin aging","score":36.04897196,"snippet":"BDNF (Brain-Derived Neurotrophic Factor) ist ein Protein, das vor allem für seine Rolle im Nervensystem bekannt ist.

Carriers of the Met allele show reduced BDNF secretion in some studies and may benefit particularly from regular endurance exercise to support cognitive function. However, the effect is small and not deterministic – exercise is beneficial for everyone regardless of genotype. Direct-to-consumer DNA tests like MyBody-X can provide this hint, but they measure only a single SNP, not the full biological complexity. The evidence is based on observational and mechanistic studies, not on randomized controlled trials that prove genotype-specific exercise recommendations. Therefore, the predictive power is limited. A healthy lifestyle with adequate exercise, sleep, and nutrition remains the most important factor for brain health. The variant alone does not justify specific supplementation or drastic changes. Consult a physician or sports medicine specialist for personalized advice.","area":"gesundheit","canonical_id":"gesundheit:canonical-4ce5cc684d98f08b49f1b5f1","id":"public-1a560d101d0ddc36328e4790","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs facts: BDNF and skin aging","score":35.64111794,"snippet":"The BDNF variant rs6265 (Val66Met) is well-studied: it influences the secretion of brain-derived neurotrophic factor, which is crucial for neuronal plasticity and the response to physical activity.
