The manifestation of sensitive skin occurs as a consequence of increased permeability of the Stratum corneum, besides the involvement of neuro-immune-endocrine system. In this study, we evaluated the effects of an active ingredient SensC on the production of neuropeptides substance P (SP), enkephalin and β-endorphin; eicosanoids prostaglandin E2 (PGE2) and leukotriene B4 (LTB4); histamine, transient receptor potential vanilloid subfamily member 1 (TRPV1), and envelope proteins filaggrin and involucrin, using an in vitro model of human cell culture. Our results demonstrated that treatment of keratinocyte cultures with SensC prevented the increase of all evaluated inflammatory mediators induced by interleukin-1 alpha (IL-1α). As the same way, SensC provides decrease in the synthesis of TRPV1. Regarding the synthesis of envelope proteins, SensC promoted increases for filaggrin and involucrin levels, when compared to control group. Considering the absence of appropriate treatment, the availability of ingredients, such as SensC, with antiinflammatory and protective barrier properties can be a significant tool for preventing neurosensorial symptoms associated with sensitive skin.

More about this publication?
  • Inflammation & Allergy - Drug Targets aims to cover all the latest and outstanding developments on the medicinal chemistry, pharmacology, molecular biology, genomics and biochemistry of contemporary molecular targets involved in inflammation and allergy e.g. disease specific proteins, receptors, enzymes, genes. Each issue of the journal contains a series of timely in-depth reviews written by leaders in the field covering a range of current topics on drug targets involved in inflammation and allergy. As the discovery, identification, characterization and validation of novel human drug targets for anti-inflammation and allergy drug discovery continues to grow, this journal has become essential reading for all pharmaceutical scientists involved in drug discovery and development.
