自身免疫可能导致视网膜变性。这些研究检查了naïve营养不良RCS大鼠在视网膜变性过程中对视网膜的自身免疫反应的演变。我们发现,抗视网膜自身抗体和T细胞的产生是对视网膜变性期间死亡的感光细胞释放的抗原物质的可用性的反应,但具有独特的激活趋势。抗视网膜抗体的被动转移通过破坏BRB、上调MCP-1、吸引血液巨噬细胞进入视网膜和增加凋亡的光感受器细胞死亡来促进疾病进展。我们的研究结果直接将抗视网膜自身抗体与活化的巨噬细胞进入及其在神经变性中的可能作用联系起来。
Autoimmunity may contribute to retinal degeneration. The studies examined the evolution of autoimmune responses against retina in naïve dystrophic RCS rats over the course of retinal degeneration. We showed that anti-retinal autoantibodies and T cells are generated in response to the availability of antigenic material released from dying photoreceptor cells during retinal degeneration but with distinctive activation trends. Passive transfer of anti-retinal antibodies enhanced disease progression by disrupting the BRB, upregulating MCP-1, attracting blood macrophages into retina, and augmenting apoptotic photoreceptor cell death. Our findings directly link anti-retinal autoantibodies to activated macrophage entry and their possible role in neurodegeneration.
