Inflammasomes

Multiprotein complex that promotes inflammation by processing inactive precursor forms of pro-inflammatory cytokines such as IL-1 and IL-18.

Proinflammatory cytokines IL-1β, TNF, and IL-6.

Sensing mechanism used by cells to detect incorrect chromosome attachments is based on tension.

#Unit 2. Cellular Organization

If Amphitelic attachment occur  Microtubules pull kinetochores; cohesins resist this pulling force. The resulting tension leads to the outer kinetochore component Ndc80 being pulled away from the protein kinase Aurora B

#Unit 2. Cellular Organization

The Aurora protein kinase family members Aurora A and Aurora B and their associated regulatory factors sense kinetochores that are not under tension and sever these microtubule attachments

Condensin association with chromosomes is facilitated by mitotic CDKs and Aurora B, which phosphorylate histone H2A, allowing condensins to bind chromatin.
