Title Adoptive Cellular Gene Therapy for the Treatment of Experimental Autoimmune Polychondritis Ear Disease.
Journal ORL J Otorhinolaryngol Relat Spec
Abstract In the past, the clinical therapy for autoimmune diseases, such as autoimmune polychondritis ear disease, was mostly limited to nonspecific immunosuppressive agents, which could lead to variable responses. Currently, gene therapy aims at achieving higher specificity and less adverse effects. This concept utilizes the adoptive transfer of autologous T cells that have been retrovirally transduced ex vivo to express and deliver immunoregulatory gene products to sites of autoimmune inflammation. In the animal model of collagen-induced autoimmune polychondritis ear disease (CIAPED), the adoptive transfer of IL-12p40-expressing collagen type II (CII)-specific CD4+ T-cell hybridomas resulted in a significantly lower disease incidence and severity compared with untreated or vector-only-treated animals. In vivo cell detection using bioluminescent labels showed that transferred CII-reactive T-cell hybridomas accumulated in the inflamed earlobes of the mice with CIAPED. In vitro analysis demonstrated that IL-12p40-transduced T cells did not affect antigen-specific T-cell activation or systemic anti-CII Ab responses. However, IL-12p40-transduced T cells suppressed IFN-γ and augmented IL-4 production, indicating their potential to act therapeutically by interrupting Th1-mediated inflammatory responses via augmenting Th2 responses. These results indicate that the local delivery of IL-12p40 by T cells could inhibit CIAPED by suppressing autoimmune responses at the site of inflammation.
