Intermediate filaments
- A rim-and-spoke hypothesis to explain the biomechanical roles for cytoplasmic intermediate filament networks
Summary: The cytoplasmic intermediate filament comprises a rim and spoke arrangement supporting the plasma membrane and connecting to the nucleus, to deliver their mechanosensory functions.
- A mutation in keratin 18 that causes caspase-digestion resistance protects homozygous transgenic mice from hepatic apoptosis and injury
Summary: K18 that is resistant to caspase digestion helps to maintain keratin filament organization and delays apoptosis, thereby protecting liver from injury.
- Desmin and αB-crystallin interplay in the maintenance of mitochondrial homeostasis and cardiomyocyte survival
Highlighted Article: Both desmin and its partner chaperone αB-crystallin associate with mitochondria–sarcoplasmic-reticulum contact sites (MAMs), stabilizing MICOS super-complexes, and thus contributing to proper mitochondrial cristae structure–function.
