Structural Transition of Trichocyte Keratin Intermediate Filaments During Development in the Hair Follicle.
Fraser RD, Parry DA. Fraser RD, et al. Subcell Biochem. 2017;82:131-149. doi: 10.1007/978-3-319-49674-0_5. Subcell Biochem. 2017. PMID: 28101861 Review.
The second structure occurs at a later stage of hair development in the upper part of the follicle, where there is a transition to an oxidizing environment. Crosslinking studies reveal that molecular slippage occurs within the IF upon oxidation and that this results …
