🦠 𝐂𝐨𝐮𝐥𝐝 𝐍𝐀𝐃𝐏𝐇 𝐎𝐱𝐢𝐝𝐚𝐬𝐞 𝐁𝐞 𝐭𝐡𝐞 𝐊𝐞𝐲 𝐭𝐨 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐋𝐮𝐩𝐮𝐬? 🔬 Delve into the surprising dual functions of NADPH oxidase in lupus and its potential therapeutic implications. 🧬 𝐍𝐀𝐃𝐏𝐇 𝐨𝐱𝐢𝐝𝐚𝐬𝐞 (𝐍𝐎𝐗𝟐) 𝐡𝐚𝐬 𝐞𝐦𝐞𝐫𝐠𝐞𝐝 𝐚𝐬 𝐚 𝐜𝐫𝐢𝐭𝐢𝐜𝐚𝐥 𝐩𝐥𝐚𝐲𝐞𝐫 𝐢𝐧 𝐬𝐲𝐬𝐭𝐞𝐦𝐢𝐜 𝐥𝐮𝐩𝐮𝐬 𝐞𝐫𝐲𝐭𝐡𝐞𝐦𝐚𝐭𝐨𝐬𝐮𝐬 (𝐒𝐋𝐄), a complex autoimmune disease. Recent research shows that the absence of NOX2 exacerbates SLE symptoms, shedding light on its multifaceted role in immune regulation. 🔍 𝐁𝐲 𝐮𝐭𝐢𝐥𝐢𝐳𝐢𝐧𝐠 𝐜𝐨𝐧𝐝𝐢𝐭𝐢𝐨𝐧𝐚𝐥 𝐤𝐧𝐨𝐜𝐤𝐨𝐮𝐭 𝐦𝐨𝐝𝐞𝐥𝐬 in MRL.Faslpr SLE-prone mice, researchers discovered that deleting NOX2 in macrophages worsens nephritis. Surprisingly, knocking out NOX2 in B cells resulted in severe glomerulonephritis and interstitial nephritis, comparable to the effects of global NOX2 deletion. 🌟 𝐓𝐡𝐞 𝐬𝐭𝐮𝐝𝐲 𝐡𝐢𝐠𝐡𝐥𝐢𝐠𝐡𝐭𝐬 𝐓𝐋𝐑𝟕 𝐚𝐬 𝐚 𝐤𝐞𝐲 𝐝𝐫𝐢𝐯𝐞𝐫 𝐨𝐟 𝐒𝐋𝐄 𝐩𝐚𝐭𝐡𝐨𝐥𝐨𝐠𝐲, with NOX2 acting as a crucial regulator that suppresses TLR7-mediated NF-κB signalling in B cells. This dual role emphasizes the importance of NOX2 in both myeloid and B cell compartments in the context of SLE. 🤔 𝐇𝐨𝐰 𝐦𝐢𝐠𝐡𝐭 𝐭𝐡𝐞𝐬𝐞 𝐢𝐧𝐬𝐢𝐠𝐡𝐭𝐬 𝐢𝐧𝐭𝐨 𝐍𝐎𝐗𝟐 𝐚𝐧𝐝 𝐓𝐋𝐑𝟕 𝐬𝐢𝐠𝐧𝐚𝐥𝐢𝐧𝐠 𝐢𝐧𝐟𝐨𝐫𝐦 𝐧𝐞𝐰 𝐭𝐡𝐞𝐫𝐚𝐩𝐞𝐮𝐭𝐢𝐜 𝐬𝐭𝐫𝐚𝐭𝐞𝐠𝐢𝐞𝐬 𝐟𝐨𝐫 𝐚𝐮𝐭𝐨𝐢𝐦𝐦𝐮𝐧𝐞 𝐝𝐢𝐬𝐞𝐚𝐬𝐞𝐬? 👣 Follow me for more great content on cutting-edge innovations! https://lnkd.in/dGihRk-q #Autoimmunity #Lupus #Immunology
