Scientists Reverse Aging Damage?
42sThe claim of reversing 'irreversible' aging damage is highly controversial and sparks curiosity.
▶ Play ClipAI Summary
This video discusses a groundbreaking study published in Nature Communications that challenges the long-held belief that aging damage caused by glycation is irreversible. Researchers used directed bacterial evolution to create a novel enzyme called CMLase, which successfully removed glycation damage in human tissues, marking a potential shift from slowing aging to actively reversing it.

The Problem of Glycation
Glycation is a process where sugars bind to structural proteins over time, forming advanced glycation end products (AGEs), which cause stiffening and inflammation.
[00:17]
New Research Challenges Irreversibility
A pioneering study in Nature Communications demonstrated that glycation damage is not irreversible, contrary to previous beliefs.
[00:31]
Creation of CMLase
Through five rounds of directed bacterial evolution, scientists created a new enzyme called CMLase, which removed glycation damage by 70% in arteries and 55% in skin of aging human tissues.
[00:45]
Importance of Reversing AGEs
Even if systemic aging is reversed through exosomes or epigenetic reprogramming, processes like AGE formation still need to be addressed, making this research crucial.

Question to Audience
The video asks whether we can officially transition from slowing aging to actively reversing it, inviting viewers to share their thoughts.
The research represents a significant early step toward reversing aging damage, though it is still in very early stages. The ability to reverse glycation damage could be essential for comprehensive anti-aging therapies.

[00:03] повреждения, вызванные старением клеток. На протяжении десятилетий наука о долголетии сталкивалась с огромным препятствием — гликированием. В этот момент сахара со временем связываются со структурными белками , образуя конечные продукты гликирования, или AGEs. Они вызывают уплотнение
[00:17] воспаление. Однако новаторское исследование, опубликованное в журнале Nature Communications, развеяло убеждение в том, что этот ущерб необратим. С помощью пяти раундов направленной бактериальной эволюции ученые создали совершенно новый фермент, получивший название
[00:31] CMLase. В стареющих тканях человека CMLase удаляла повреждения, вызванные гликированием, на 70% в удаляла повреждения, вызванные гликированием, на 70% в артериях и на 55% в коже, уменьшая повреждение кожи. Несмотря на то, что это очень ранняя стадия разработки, она имеет решающее значение. Даже
[00:45] если мы найдем способ обратить вспять системное старение с помощью экзосом или эпигенетического перепрограммирования, нам все равно нужно будет обратить вспять такие процессы, как образование конечных продуктов гликирования (AGEs). Можно ли официально перейти от простого замедления старения к его активному обращению вспять? Поделитесь
