Keratinocyte Inhibitor

A "keratinocyte inhibitor" refers to any agent that inhibits the function, proliferation, differentiation, or survival of keratinocytes, the predominant cell type in the epidermis. It encompasses a range of targets and mechanisms. Examples include EGFR inhibitors (e.g., erlotinib, gefitinib) that reduce keratinocyte growth and promote differentiation, ROCK inhibitors like Y-27632 that modulate differentiation, and certain cytokines like IL-22 that inhibit terminal differentiation. These inhibitors are relevant in dermatology for diseases like psoriasis, in oncology for managing cutaneous adverse reactions during cancer therapy, and in immunology for investigating immune regulation in the skin.
