Abstract

Psoriasis is a multifactorial autoimmune skin disorder based on irregularities of the T- cell function. The abnormal keratinocyte hyper proliferation in psoriasis arises due to the activation of T-cells which produces rich amount of arachidonic acid leads to generation of various proinflammatory mediators like PGs, LTs, cytokines and adhesion molecules via MAPK/AP-1, EARK1/2 and protein kinase – C (PKCs) activation pathways. Incorporation of naturally occuring bioactives like, omega (ω) - 3 fatty acids (i.e., EPA and DHA) in a dose dependent manner results in inhibition of various pro-inflammatory mediators and metabolization of EPA and DHA leads to dampening of inflammation and higher resolution of the skin abnromalities. These all due to the promotion of the synthesis of ω-3 PUFA-derived lipid mediators viz namely resolvins and protectins. These have been widely used alone or in combination with other drugs in the treatment of psoriasis. Despite of their meritorious visages, the use of these bioactives is associated with several hiccups like higher unstability and vulnerable to degradation due to lipid peroxidation, poor and incosistent bioavilability by oral and topical administration. The potential use of nanomedicines in the delivery of such bioactives has gained wider attention owing to their promising bioavailability enhancement characteristics, improved stability and better efficacy. The present review gives an extensive account on ω-3 fatty acids (EPA and DHA) starting from seedling to apex, including biosynthesis, metabolites, and its mechanism of action in psoriasis. Moreover, barriers in the effective delivery of ω-3 fatty acids and how nanomedicines can be fit in the scope of its therapeutic delivery in psoriasis have also been addressed. Despite numerous advantages, application of EPA-DHA as ω-3 fatty acids therapeutics in the management of psoriasis are still at an initial stage. Nanomedicines approach to achieve high bioavailable delivery with safety and stability of ω-3 fatty acids showing the promising area for the future in psoriasis management.
