Blocking a key protein may turn radiation-reprogrammed immune cells against cancer

ایک اہم پروٹین کو روکنا تابکاری سے بدلے ہوئے مدافعتی خلیوں کو کینسر کے خلاف کر سکتا ہے

एक प्रमुख प्रोटीन को रोकना विकिरण से बदली प्रतिरक्षा कोशिकाओं को कैंसर के खिलाफ कर सकता है

Blocking a key protein may turn radiation-reprogrammed immune cells against cancer

Key points

اہم نکات

मुख्य बातें

  • University of Chicago researchers have found a way to reverse a harmful side effect of radiation therapy.
  • Radiation activates a protein called TET2 in immune cells made in the bone marrow, locking them into a state that suppresses the body's defences and helps tumours grow.
  • In mouse models of colon, melanoma and lung cancer, blocking TET2 made the same cells fight cancer instead, helping radiation and immunotherapy shrink tumours and control spread.
  • شکاگو یونیورسٹی کے محققین نے تابکاری تھراپی کے ایک نقصان دہ اثر کو الٹنے کا طریقہ پایا ہے۔ تابکاری ہڈیوں کے گودے میں بننے والے مدافعتی خلیوں میں ٹی ای ٹی 2 نامی پروٹین کو فعال کر دیتی ہے، جس سے وہ جسم کے دفاع کو دبانے اور ٹیومر کی نشوونما میں مدد کرنے کی حالت میں بند ہو جاتے ہیں۔ بڑی آنت، میلانوما اور پھیپھڑوں کے کینسر کے چوہوں کے ماڈلز میں ٹی ای ٹی 2 کو روکنے سے یہی خلیے کینسر کے خلاف لڑنے لگے، جس سے تابکاری اور امیونو تھراپی نے ٹیومر سکڑنے اور پھیلاؤ پر قابو پانے میں مدد کی۔ کینسر سیل میں شائع ہونے والی یہ تحقیق، جو جزوی طور پر پھیپھڑوں کے جدید کینسر کے 33 مریضوں پر مبنی ہے، ابھی ابتدائی تحقیق ہے اور علاج نہیں، لیکن یہ تابکاری تھراپی بہتر بنانے کے لیے ایک ممکنہ نیا ہدف دکھاتی ہے۔
  • शिकागो विश्वविद्यालय के शोधकर्ताओं ने विकिरण चिकित्सा के एक हानिकारक दुष्प्रभाव को उलटने का तरीका खोजा है। विकिरण अस्थि मज्जा में बनी प्रतिरक्षा कोशिकाओं में टीईटी2 नामक प्रोटीन को सक्रिय कर देता है, जिससे वे शरीर की सुरक्षा को दबाने और ट्यूमर बढ़ने में मदद करने की स्थिति में बंद हो जाती हैं। आंत, मेलेनोमा और फेफड़ों के कैंसर के चूहे के मॉडलों में टीईटी2 को रोकने से वही कोशिकाएं कैंसर से लड़ने लगीं, जिससे विकिरण और इम्यूनोथेरेपी ने ट्यूमर सिकोड़ने और फैलाव रोकने में मदद की। कैंसर सेल में प्रकाशित यह अध्ययन, जो आंशिक रूप से फेफड़ों के उन्नत कैंसर के 33 रोगियों पर आधारित है, अभी शुरुआती शोध है और इलाज नहीं है, लेकिन यह विकिरण चिकित्सा सुधारने के लिए एक संभावित नया लक्ष्य दिखाता है।

University of Chicago researchers have found a way to reverse a harmful side effect of radiation therapy. Radiation activates a protein called TET2 in immune cells made in the bone marrow, locking them into a state that suppresses the body's defences and helps tumours grow. In mouse models of colon, melanoma and lung cancer, blocking TET2 made the same cells fight cancer instead, helping radiation and immunotherapy shrink tumours and control spread. The study, published in Cancer Cell and based partly on 33 patients with advanced lung cancer, is early research and not yet a treatment, but it points to a possible new target for improving radiation therapy.
