Answer:
The keratin-producing cells known as keratinocytes are the primary type of cells found in the epidermis. They originate from the stratum basale's stem cells. They act as a barrier from harmful environmental elements like pathogens and ultraviolet radiation. Dermatophytes are a group of physiologically and morphologically associated molds, which release an enzyme keratinase.
Keratinases are the serine proteases that destroy the keratin found in skin, nails, and hair.
The dermatophytes lead to infections of the hair, skin, and nails, as they obtain nutrients from the keratinized substances. These pathogenic fungi are most actively found in the external cornified layers of the cells of dead skin were they less likely to get determined and eliminated by the active dendritic cells.
