Current treatment approaches for psoriasis aim to alleviate symptoms and prevent disease progression, including systemically administered drugs with whole body side effects. Despite some advances in psoriasis treatment, success has been quite limited. To begin to address this challenge, we undertook an initial investigation of whether transcutaneous delivery of an endogenous anti-inflammatory cytokine could provide an effective, local treatment of psoriatic-like skin conditions. To do this, we utilized a previously documented rodent model of psoriasis, induced via a single topical application of Imiquimod (IMQ) to the shaved back of rats. The therapeutic approach used for this initial investigation was delivery of plasmid DNA encoding rat interleukin-10 (pDNA-rIL10), a non-viral gene therapy approach previously shown to be effective in suppressing neuroinflammatory disorders after localized delivery either intracerebrally or intrathecally. Translation of this CNS therapeutic for use in psoriatic-like skin disorders required reformulation to enable transcutaneous delivery. Toward that end, pDNA-rIL10 was topically applied in Lipoderm HMW, a base explicitly designed to deliver higher molecular weight compounds into skin. Here we show that a single topical application of pDNA-rIL10 in Lipoderm HMW was effective in decreasing mRNA levels of pro-inflammatory cytokines as well as reducing the recruitment of T-cells to IMQ-treated skin. Furthermore, this transcutaneous IL-10 gene therapy decreased signs of skin inflammation, reflected by reduced erythema. Moreover, the results provide an initial indication that IL10 may stimulate hair regrowth in psoriatic-like skin.</p>","PeriodicalId":9199,"journal":{"name":"Brain, Behavior, and Immunity","volume":null,"pages":null},"PeriodicalIF":8.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142567249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deep brain stimulation (DBS), which is used as a symptomatic treatment, could halt this progressive decline. By analyzing specific immune populations from a second cohort of patients, we could show that DBS causes a shift from the pro-inflammatory CD4⁺ T helper 17 cells driving neurodegeneration to anti-inflammatory CD4⁺ regulatory T cells.
