摘要
Psoriasis is a chronic and recurrent skin problem that affects 3% of the global population. Nowadays, most medicines may not promise a complete cure for patients with psoriasis because of the development of pharmacoresistance and the side effects of drugs due to the microenvironment impact in the context of skin imbalance. Herein, we attempt to explore the pharmaceutical efficacy of Scutellaria baicalensis (S. baicalensis) in modulating the microenvironment created by macrophages and keratinocytes in psoriasis. The results indicated that treatment of S. baicalensis extract significantly reduced the thickness of epidermis and attenuated psoriatic lesions. Moreover, S. baicalensis extract obviously inhibited the activation and infiltration of macrophages by alleviating inflammatory factors such as nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and cyclooxygenase-2 (COX-2). The administration of S. baicalensis extract also remarkably abolished oxidative damage upon DNA and proteins, which attributed to the activation of nuclear factor erythroid 2-related factor-2 (Nrf2) and heme oxygenase-1 (HO-1). The network analysis of redox proteomics and cytokine profiles suggested that S. baicalensis administration regulated the specific pathways associated with oxidative stress, inflammation and cytokine signaling cascades to ameliorate the macrophage-targeted responses and subsequently arrest proliferation of keratinocytes. Collectively, our findings highlighted the importance of S. baicalensis application in reprogramming microenvironment to provide an alternative and complementary intervention for long-term psoriatic therapy.
