Impaired adhesion is driven by changes in tubulin levels and microtubule stability.
Reducing tubulin (T007-1) or mild destabilization (nocodazole) rescues the phenotype, while hyperstabilization (taxol) worsens it.
📌Tubulin homeostasis supports multicellular organization.

How?
Loss of autoregulation disrupts localization of adhesion molecules like N-Cadherin, Fibronectin, and Integrin α5: cells round up and lose anchorage.
📌Restoring adhesion (via E-Cadherin over expression or ECM) rescues tissue integrity and viability.

Tubulin autoregulation is essential for spheroid architecture & viability. Without it:
- cells detach (corona forms)
- cell death increases
📌This phenotype isn’t due to cell cycle defects or migration — it reflects impaired cell adhesion.

Loss or mutation of TTC5, the key mediator of tubulin autoregulation, increases tubulin mRNA and protein levels in 3D spheroids. This leads to microtubule hyperstability and reorganization of the network.
📌Tubulin levels matter (even in steady state!)

Did you know the cell wall of mycobacteria isn’t just for protection? 🧱👀 Here, Mycobacterium marinum sheds its outer capsule right after being eaten by Dicty! A sneaky move that affects even nearby cells… #FluorescenceFriday #Mycobacteria #CellBiology #Infection #3Rmodels #Phagocytosis

New lab preprint! Unveiling the Molecular Architecture of T Cells and Immune Synapses with Cryo-Expansion Microscopy (Cryo-ExM). A fantastic collaboration with Dr. Benita Wolf. Congratulations to all authors, especially Florent Lemaitre, for leading this amazing work! www.biorxiv.org/content/10.1...

🔬 A new probe developed by Janelia researchers & collaborators that enables visualization of extracellular matrix structure in live tissues could also be useful in studying diseases linked to changes in the extracellular matrix and in diagnostic imaging ➡️ www.janelia.org/news/looking...

Behold: a human cancer spheroid! This 3D cell blob models solid tumors. DAPI (blue) marks nuclei, PI lights up the dead. Z-plane colors unveil a rainbow necrotic core wrapped in a moody, monochrome outer layer. #fluorescencefriday #microscopy #postdoc
