Julie Theriot (Stanford, HHMI) 1: Protein Polymers, Crawling Cells and Comet Tails

[@YouTubist666]

That was very informative. Dr. Theriot spoke a little too fast, but surprisingly I was able to keep up. A testament to her speaking ability. Very clearly presented. This is a great channel.

That's the beauty of a video. You can pause it. You can rewind and watch it again. When I come across terminology that I'm unfamiliar with I pause the video, when the opportunity arises and I look up the word. I go from Wikipedia Rabbit Hole to Wikipedia rabbit hole. Then I come back and contextualize. 😉

Listeria de verdad surfea en el citoplasma ! La conferencia fue muy informativa no tenia idea de que eran las colas de cometa ni mucho menos que pudiese ser un mecanismo así de rápido

[@fburton8]

Utterly fascinating lecture.

[@rickfearn3663]

Absolutely riveting and inspiring!!! I had no idea that Listeria monocytogenes could use actin polymerization to propel themselves through the cytoplasm. You must view this video. Rick

I watched your second lecture first then decided to spend time in your first. Very illuminating experiments well crafted talk. thank you!! as a graduate student, thank you for the shout out to everyone involved in each project, always nice to hear where the work comes from. =]

[@MetaphysicalAxiom]

Good to recognize the origin of swarm processing. We do nothing alone. 😉

Who produces a thought? Who produces the framework of which to think by? Who collected all the knowledge to build that framework? We are the batons in the relay race of mass awareness.

beautiful work, great lecture. thank you!

[@StewartChaimson]

What a pleasure to watch this lecture; thank you so much!

[@michaelfourie345]

Fantastic....I was glued to my chair. Thank you.Have you done any other lectures that might be available to us? (apart from part 2, I mean)

[@HowlsFury]

Really great lecture, Thank you

[@hectorricardodelacruzmonte2566]

i have no words Thank you!

14:17 From where do they get this excellent knowledge of biology?

[@VR_Wizard]

Great lecture easy to follow.

[@魏寅生]

Very illuminating and interesting. However the title doesn't describe the organization of the lecture very well. Comet tail is looked at before the mechanism of cell crawling. But probably many viewers are not as familiar with comet tails so it's fine to name the lecture this way, I suppose.

[@numericalcode]

This explains a lot

[@gloshka]

A very interesting lecture, thank you! Can you really say about two living cells that they are separated by X million years of evolution? The are both here today so it seems that they had the same amount of evolution.

[@jeasylife6683]

Fantastic

[@patrickbeauchamp5019]

What is nucleation mean?

[@imagination7710]

I think its the initial 'seed' from which the polymers grow: there is a threshold number of actin which must collide and form this 'nucleus' in order for polymerisation to occur

[@je6874]

Nucleation is the process of forming a seed, which is usually 3 actin monomers (G-actin) associated together... this dramatically increases the energy of interaction and allows loads of G-actin monomers to polymerase to form F-actin. In cells, nucleation is controlled by nucleators such as Arp2/3 and Formin to catalyse the formation of seeds (Arp2/3 essentially mimics 2 actin monomers so only one G-actin is needed to form the seed).

[@MetaphysicalAxiom]

@@je6874 I'm surprised more questions didn't ensue.

[@unorthodoccc]

Awesome

[@locke8847]

How is everyone okay with this??????

[@mrvzhao]

Remember the masked villain from Big Hero 6? Now I know what his mode of motility was inspired by.
