Keratin bioactive peptides for the treatment of skin disorders

Abstract

[Excerpt] Several skin disorders, like chronic wounds and psoriasis involve several steps for skin regeneration. On wound repair keratinocyte migration for reepithelialization is required. Psoriatic lesions result from the interaction between hyperproliferative keratinocytes, inflammatory cells and immune cells. Chicken feather (CF) are composed by keratin and its disposal is a critical problem. It is possible to hydrolyze (CF) to obtain high value keratin peptides minimizing the impact on the environment and giving value to otherwise waste material. [...]
