Abstract

PURPOSE: Plasmid electrotransfer in the ciliary muscle allows the sustained release of therapeutic proteins within the eye. The aim of this study was to evaluate whether the ocular production of TNF-alpha soluble receptor, using this nonviral gene therapy method, could have a beneficial local effect in a model of experimental autoimmune uveoretinitis (EAU). METHODS: Injection of a plasmid encoding a TNF-alpha p55 receptor (30 microg) in the ciliary muscle, combined with electrotransfer (200 V/cm), was carried out in Lewis rat eyes 4 days before the induction of EAU by S-antigen. Control eyes received naked plasmid electrotransfer or simple injection of the therapeutic plasmid. The disease was evaluated clinically and histologically. Cytokines and chemokines were analyzed in the ocular media by multiplex assay performed 15 and 21 days after immunization. RESULTS: Ocular TNF-alpha blockade, resulting from the local secretion of soluble receptors, was associated with delayed and significantly less severe uveitis, together with a reduction of the retinal damages. Compared with the controls, treated eyes showed significantly lower levels of IL-1beta and MCP1, higher levels of IL-13 and IL-4, and reduced NOS-2 expression in infiltrating cells. Treatment did not influence TNF-alpha levels in inguinal lymph nodes. CONCLUSIONS: Taken together, these results indicate that local immunomodulation was achieved and that no systemic adverse effects of TNF-alpha blockade observed after systemic injection of TNF-alpha inhibitors should be expected.

  • Postoperative inflammation after electrotransfection could not be accurately assessed because the studies were done on animal models of intraocular inflammation.

    “Postoperative inflammation could not be accurately assessed as the studies were done on animal models of intraocular inflammation.”

    From Ocular Gene Therapy: A Literature Review with Special Focus on Immune and Inflammatory Responses (2022) · cites this paper as [33]

    The Experimental Design and Electrotransfer to Ciliary Muscle section (page not indicated) confirms that the study used electrotransfer in rats before inducing experimental autoimmune uveitis. The paper does not say that postoperative inflammation could not be accurately assessed because of that model; its Induction and Clinical Assessment of EAU section instead describes assessment of uveitis severity. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • In studies performed on rabbits and rodents, there were no reported safety issues with electrotransfection.

    “In different studies performed on rabbits and rodents, there were no reported safety issues.33,102–104”

    From Ocular Gene Therapy: A Literature Review with Special Focus on Immune and Inflammatory Responses (2022) · cites this paper as [33]

    The Experimental Design section describes electrotransfer in rats, and the Discussion reports no circulating soluble receptors in treated rats, suggesting that systemic adverse effects associated with injected TNF inhibitors should not result. The paper does not report rabbit experiments or establish that electrotransfer had no safety issues overall. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • Electrotransfection was effective in decreasing ocular inflammation in animal models of intraocular inflammation.

    “However, the studies demonstrated that electrotransfection was effective in decreasing ocular inflammation in these models.33,102–104”
  • There were no histological or functional electroretinogram toxicities following electrotransfection.

    “There were no histological or functional (electroretinogram) toxicities following electrotransfection.”

    From Ocular Gene Therapy: A Literature Review with Special Focus on Immune and Inflammatory Responses (2022) · cites this paper as [33]

    The Photoreceptor Rescue section (page unavailable) reports less histologic damage in treated rats with autoimmune uveoretinitis, but that measures disease severity rather than whether electrotransfer itself caused toxicity. Searches for electroretinogram/ERG and ocular toxicity found no functional safety assessment or statement that histological toxicity was absent. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
