  • Title: Overcoming or circumventing the stratum corneum barrier for efficient transcutaneous immunization.
    Author: Chen Z, Lv Y, Qi J, Zhu Q, Lu Y, Wu W.
    Journal: Drug Discov Today; 2018 Jan; 23(1):181-186. PubMed ID: 28988995.
    Abstract:
    Transcutaneous immunization (TCI) is a promising alternative to vaccine delivery via the subcutaneous and intramuscular routes because of the unique immunological characteristics of the skin. However, the stratum corneum (SC) prevents entry of most therapeutic compounds into the body. Several physical devices have been developed to overcome the SC barrier, but still damage the skin. However, by targeting antigens to the abundant perifollicular antigen-presenting cells (APCs), the transfollicular route might be a promising approach for TCI without compromising the skin barrier.
