Hi! My name is Joyce and I love building and using tools to manipulate the #cytoskeleton of cells to better understand their function. 🔬
Below you can see my movie of #opto-katanin ✂️(SspB-mCh-p60) being used to locally disassemble #microtubules (labelled by SiR-tubulin) inside a neuron.

Our new preprint is about the airway epithelium microtubule network, cilia, basal body protein composition, averaging of volumetric fluorescence data, and expansion microscopy.
Four years of very hard work from our very talented Emma van Grinsven. www.biorxiv.org/content/10.1... (1/N)

Excited to share that our fast & reversible chemical and optogenetic vimentin pulling tools are now published in JCB! 🥳
We show a subset of organelles are displaced with vimentin pulling to the cell centre and cells become much softer despite little or no effect on actin/MTs

Thrilled to share our latest preprint from @yiechanglin.bsky.social & @ciarawallis.bsky.social showing that AF2-Multimer and AF3 can quickly & accurately predict the oligomeric states & structures of proteins (& maybe can identify multiple biologically relevant oligomeric states 👀)

Hi! I was wondering if anyone had successfully cultured happy HEK293T cells in defined serum alternatives? If so, what did you use?

Excited to share our new pre-print showcasing tools (chemical & optogenetic) for repositioning Vimentin in cells! Movie shows ER (Halo-KDEL) sheets being relocalized together with vimentin (Vim) upon local vimentin pulling in U2OS. @gijsjekoenderink.bsky.social

CAMSAP3 stretches (microtubule -end binding protein) are shown in yellow. They move towards the Soma in developing neurons.
Hi! I'm Max. I'm developing a #biophysical model of #microtubules in #neurons during #development. The model is based on my surprising experimental finding (lots of live-cell imaging) that the entire microtubule array in neurites flows retrogradely into the soma: www.science.org/doi/10.1126/... 🧪 🧠📈
