- Proteases are hydrolytic enzymes capable of cutting peptide bonds. A number of them are now known to play an essential role in terms of the balance and physiology of the epidemic.
- the epidemic is conventionally divided into a basal layer of keratinocytes constituting the germinal layer of the epidemic, a so-called spiny layer consisting of several layers of polyhedral cells arranged on the germinal layers, one to three so-called granular layers consisting of flattened cells containing distinct cytoplasmic inclusions, keratohyaline grains and finally, a set of upper layers called corneal layers (or stratum corneum), consisting of keratinocytes at the terminal stage of their differentiation called corneocytes.
- corneal layers or stratum corneum
- Corneocytes are anucleated cells mainly made up of a fibrous material containing cytokeratins, surrounded by a comedic envelope. There is constantly production of new keratinocytes to compensate for the continuous loss of epidermal cells in the stratum corneum according to a mechanism called desquamation. An imbalance between the production of cells at the level of the basal layer and the scaling rate can in particular lead to the formation of scales on the surface of the skin.
