New US project explores treatments to protect brain from alphavirus infections

امریکہ کا نیا منصوبہ الفا وائرس انفیکشن سے دماغ کو بچانے کے علاج پر تحقیق کرے گا

नई अमेरिकी परियोजना अल्फावायरस संक्रमण से मस्तिष्क की रक्षा के उपचार खोजेगी

New US project explores treatments to protect brain from alphavirus infections

Key points

اہم نکات

मुख्य बातें

  • A researcher at the University of Alabama in Huntsville is leading a five-year, $3.67 million project funded by the US National Institutes of Health to advance potential treatments for alphaviruses, mosquito-borne viruses for which no vaccine or treatment is currently approved for humans.
  • The project will test small-molecule compounds designed to block viral replication, targeting a viral protein called nsP2, and check whether they can protect the blood-brain barrier, the brain's key defence.
  • Earlier work showed the compounds could stop alphavirus replication in cell cultures and protect mice, and the team will also use organ-on-a-chip models of the barrier, working with George Mason University.
  • یونیورسٹی آف الاباما ان ہنٹس وِل کے ایک محقق پانچ سالہ، 3.67 ملین ڈالر کے منصوبے کی قیادت کر رہے ہیں، جسے امریکی نیشنل انسٹی ٹیوٹس آف ہیلتھ نے فنڈ دیا ہے، تاکہ الفا وائرسز کے ممکنہ علاج آگے بڑھائے جا سکیں — یہ مچھروں سے پھیلنے والے وائرس ہیں جن کے لیے انسانوں کے لیے ابھی کوئی ویکسین یا علاج منظور نہیں۔ اس منصوبے میں چھوٹے مالیکیول والے مرکبات کی جانچ کی جائے گی جو وائرل نقل کو روکنے کے لیے بنائے گئے ہیں اور nsP2 نامی وائرل پروٹین کو نشانہ بناتے ہیں، اور یہ دیکھا جائے گا کہ آیا وہ خون دماغ رکاوٹ کی حفاظت کر سکتے ہیں، جو دماغ کا اہم دفاع ہے۔ پہلے کے کام سے ظاہر ہوا تھا کہ یہ مرکبات سیل کلچر میں الفا وائرس کی نقل روک سکتے ہیں اور چوہوں کی حفاظت کر سکتے ہیں، اور ٹیم جارج میسن یونیورسٹی کے ساتھ مل کر رکاوٹ کے آرگن آن اے چپ ماڈل بھی استعمال کرے گی۔
  • हंट्सविले में अलबामा विश्वविद्यालय के एक शोधकर्ता पाँच वर्षीय, 3.67 मिलियन डॉलर की परियोजना का नेतृत्व कर रहे हैं, जिसे अमेरिकी राष्ट्रीय स्वास्थ्य संस्थानों ने वित्तपोषित किया है, ताकि अल्फावायरस के संभावित उपचार आगे बढ़ाए जा सकें — ये मच्छरों से फैलने वाले वायरस हैं जिनके लिए मनुष्यों के लिए अभी कोई टीका या उपचार स्वीकृत नहीं है। इस परियोजना में छोटे अणु वाले यौगिकों का परीक्षण किया जाएगा जो वायरल प्रतिकृति को रोकने के लिए बनाए गए हैं और nsP2 नामक वायरल प्रोटीन को लक्षित करते हैं, और यह देखा जाएगा कि क्या वे रक्त-मस्तिष्क अवरोध की रक्षा कर सकते हैं, जो मस्तिष्क का प्रमुख बचाव है। पहले के काम से पता चला था कि ये यौगिक कोशिका संवर्धन में अल्फावायरस की प्रतिकृति रोक सकते हैं और चूहों की रक्षा कर सकते हैं, और टीम जॉर्ज मेसन विश्वविद्यालय के साथ मिलकर अवरोध के ऑर्गन-ऑन-ए-चिप मॉडल भी उपयोग करेगी।
