Summary
Developing nervous system cells sense injury through their microtubule cytoskeleton. This sensing triggers cell division, enabling the replacement of damaged cells and tissue repair.
Area of Science:
- Neurobiology
- Cell Biology
- Developmental Biology
Background:
- Tissue injury can trigger compensatory cell proliferation to restore function.
- The mechanisms by which developing cells detect and respond to injury are not fully understood.
Discussion:
- Bossing et al. (2012) demonstrate that developing nervous system cells utilize their microtubule cytoskeleton to sense injury.
- This mechanosensory role of microtubules is crucial for initiating a proliferative response.
Key Insights:
- Microtubule cytoskeleton acts as a sensor for cellular damage in developing neurons.
- Injury-induced microtubule dynamics trigger cell cycle re-entry and proliferation.
- This provides a novel mechanism for neural tissue repair during development.
Outlook:
- Further research can explore therapeutic strategies targeting microtubule dynamics for neural regeneration.
- Understanding this process may offer insights into developmental disorders related to cell loss.

01:45Destabilization of Microtubules
The destabilization of microtubules can occur during different stages of the microtubule lifecycle, such as nucleation or elongation. It can take place at either end of the microtubule or in the microtubule lattices as a whole. The lifespan of individual microtubules within a cell varies according to the cell type and stage of the cell cycle. During interphase, the lifespan of the microtubule is about 30 minutes, while during cell division, it is about 15 minutes. In axonal microtubules of...
02:17Microtubule Instability
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated assembly and...

01:15Drugs that Stabilize Microtubules
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...
01:42Microtubule Associated Proteins (MAPs)
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...
01:10Drugs that Destabilize Microtubules
Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...
