Immunotherapies in cutaneous pathologies: an overview.

Skin is a vital protective organ, the main role of which is to provide a physical barrier and to prevent the entry of pathogens. Various pathologies, such as atopic dermatitis (AD), psoriasis (PSO), or skin cancers, can affect the skin, and all show a high and increasing prevalence. Many antibodies are currently used in the treatment of these diseases. However, various studies are underway for the development of new biologics directed against specific targets. In this review, we describe current biologics used in skin pathologies as well as antibodies in development. We also discuss various immunotherapy examples that use new delivery technologies, such as microneedle patch, nanoparticles (NPs), liposomes, or gel formulation.
