Intermediate filaments are a type of cytoskeletal component found in the cells of many organisms. They are part of the three main types of filaments in the cytoskeleton, alongside microfilaments and microtubules. Intermediate filaments provide structural support and help maintain the shape of cells, playing a crucial role in cellular integrity. These filaments are composed of various proteins, such as keratins, vimentin, and neurofilaments, depending on the cell type. Unlike microtubules, which are dynamic and can rapidly change, intermediate filaments are more stable and resistant to mechanical stress, making them essential for the resilience of tissues like skin and muscle.
