- Approximately 1.5 billion years ago, a lone bacterium found its way into a larger cell. The exchanges that transpired between the two are considered to have driven the evolution of this bacterium into the organelle we now call the mitochondrion. Emerging research suggests that mitochondria are not simply the 'powerhouses' of the cell, but also function as cellular guardians against microbial intruders. Consequently, maintaining mitochondrial health is not only vital for our well-being, but may serve to protect us against infectious disease.
Lena Pernas è leader di un gruppo di ricerca Max Planck e membro del CECAD presso l’MPI Biology for Ageing di Colonia, Germania. La missione del suo laboratorio è svelare i misteri di come le cellule utilizzano i mitocondri per combattere i microbi.
Ha conseguito il dottorato di ricerca in microbiologia e immunologia presso la Stanford University School of Medicine nel 2013. Il suo lavoro è stato riconosciuto con diversi premi, tra cui l‘ ERC Starting Grant, il premio per l’innovazione BINDER, e una sovvenzione per progetti pionieristici della VolkswagenStiftung.

mitochondria is the powerhouse of the cell😃
I understood that reference and tip my hat to you
Yes
That‘s schocking and sparks my curiosity
I agree
Türçe dili
Lena your confidence in incredible ❤
Excellent research and insight
Internal ecology of a cell, fascinating
The idea of endosymbiosis firsty was formed by russian scientists Konstantin Mereschkowski at the beginning of 20th century. For some time everybody had forgotten about that but then in 60's Lynn Margulis reopened this hypothesis. If I'm not mistaken she had also visited Moscow State University in 80's to talk and give a speech about her research.
She discovered the symbiotic relationship between
Nice speech, thanks!
mitochondria is the powerhouse of the cell 👾
This video is educative & entertaining altogether. We will enjoy more similar videos🎉 I learned a lot the easy way!
Why did you remove all the subtitles 😫🤧😭
Love from Syria ♥️❤️♥️☺️
I have a serious legitimate question. I am not mocking, or being sarcastic or antagonistic.
How do we know that "....about 1.5 billion years ago a bacterium found its way into a larger cell, and stayed."?
I only mean to ask this question to increase my own understanding. Any insight anyone is willing to provide is legitimately appreciated.
Life science undergraduate here: Mitochondria itself has DNA. Our cells also have DNA. These are two different complete sets of DNA. When you compare the DNA of a mitochondria to a random bacteria, it always have more similarities to the bacteria rather than the cell. U take a cell from a fish, crocodile, insect, plant, monkey then u take their dna and mitochondrial dna, it is always different. and the mitochondrial dna is always similar to a bacteria.
tldr: DNA
Wow
Everytime it helps us to have energy irrespective of it's circus👍
the only one who took "mitochondria is the powerhouse of the cell" seriously
🔝🔝🔝🔝💎
she missed the part of the ship story where they had saved all the wood they replaced n the ship and built a new one so which 1 of the 2 ships is the ship
The old wood atill makes a broken down ship. They are clones
Leading to an outstanding ‘independent’ study into the before & after effects of “policy»rushed” vaccine$ 💉 8:27
Aya Brea would like a word
Beautiful and intelligent 🙂💘
Chemistry lab says - come and do sawdust experiment with us and you could make that stick anywhere you want. Let that sound shape that bacteria body as you want 3:45, mostly because all the information technology science part now is gone cheek. This scenario you do alone is for making populate that world with shares or emojis.

Ek din me bhi yha aayunga Aditya tyagi
Do hard work nothing is impossible ❤🎉😊
Hfi
She was wrong not 1.5 billion old it is 1.55 billion years old
yeah why not? It's the powerhouse of the cell 🫡
🔝🔝🔝🔝🔝💎
