Abstract
Psoriasis is an autoimmune disorder; however, an exact underlying mechanism responsible for psoriasis is yet not known. A hypothesis put forward is an abnormal proliferation of keratinocytes due to faulty signals brought about by T-cells. Due to the lack of evidence of the exact cause, a variety of treatments have been used of which topical therapy is usually the first option in most patients. Topical therapy has several shortcomings and barriers of drug delivary which may be effectively overcome using novel drug carrier systems which exhibit maximum penetration, controlled release, reduced irritancy and, overall, a better efficacy. Thus, novel treatment strategies based on gene therapy such as antisensing nucleotide, silencing RNA complex, stem cell therapy and antibody-based therapy are being envisaged. This review article discusses the concepts and background of current novel delivery systems and gene therapy tools for effective management of psoriasis.
