Lupus study finds immune cells attack faulty protein fragments from own cells

لوپس تحقیق میں مدافعتی خلیوں کو اپنے ہی خلیوں کے خراب پروٹین ٹکڑوں پر حملہ کرتے پایا گیا

लूपस अध्ययन में प्रतिरक्षा कोशिकाओं को अपनी ही कोशिकाओं के दोषपूर्ण प्रोटीन टुकड़ों पर हमला करते पाया गया

Lupus study finds immune cells attack faulty protein fragments from own cells

Key points

اہم نکات

मुख्य बातें

  • A study published in Nature has found a new immune reaction in lupus patients.
  • In people with systemic lupus, the white blood cells called neutrophils carry many wrongly spliced gene messages, which produce protein fragments never seen in healthy cells.
  • Both T cells and antibody-making B cells in patients reacted to these fragments, known as neoantigens, as if they were foreign threats.
  • نیچر میں شائع ہونے والی ایک تحقیق میں لوپس کے مریضوں میں ایک نیا مدافعتی ردعمل پایا گیا ہے۔ سسٹمک لوپس میں مبتلا افراد میں نیوٹروفل نامی سفید خون کے خلیوں میں غلط طریقے سے جڑے ہوئے جینیاتی پیغامات ہوتے ہیں، جو ایسے پروٹین ٹکڑے بناتے ہیں جو صحت مند خلیوں میں کبھی نہیں دیکھے گئے۔ مریضوں میں ٹی خلیوں اور اینٹی باڈی بنانے والے بی خلیوں دونوں نے ان ٹکڑوں، جنہیں نیو اینٹی جنز کہتے ہیں، پر ایسے ردعمل ظاہر کیا جیسے وہ بیرونی خطرہ ہوں۔ محققین نے 34 لوپس مریضوں کا خون جانچا اور کہا کہ یہ دریافت خود کار مدافعتی بیماری کے بارے میں سائنسدانوں کی سوچ بدل سکتی ہے، حالانکہ انہوں نے خبردار کیا کہ یہ ثابت کرنے کے لیے کلینیکل ٹرائلز ابھی باقی ہیں کہ یہ ٹکڑے بیماری کو چلاتے ہیں۔
  • नेचर में प्रकाशित एक अध्ययन में लूपस के रोगियों में एक नई प्रतिरक्षा प्रतिक्रिया पाई गई है। सिस्टमिक लूपस से पीड़ित लोगों में न्यूट्रोफ़िल नामक श्वेत रक्त कोशिकाओं में गलत तरीके से जुड़े हुए आनुवंशिक संदेश होते हैं, जो ऐसे प्रोटीन टुकड़े बनाते हैं जो स्वस्थ कोशिकाओं में कभी नहीं देखे गए। रोगियों में टी कोशिकाओं और एंटीबॉडी बनाने वाली बी कोशिकाओं दोनों ने इन टुकड़ों, जिन्हें नियोएंटीजन कहते हैं, पर ऐसे प्रतिक्रिया दिखाई जैसे वे बाहरी खतरा हों। शोधकर्ताओं ने 34 लूपस रोगियों का रक्त जांचा और कहा कि यह खोज स्वप्रतिरक्षा रोग के बारे में वैज्ञानिकों की सोच बदल सकती है, हालांकि उन्होंने चेतावनी दी कि यह साबित करने के लिए नैदानिक परीक्षण अभी बाकी हैं कि ये टुकड़े रोग को चलाते हैं।

A study published in Nature has found a new immune reaction in lupus patients. In people with systemic lupus, the white blood cells called neutrophils carry many wrongly spliced gene messages, which produce protein fragments never seen in healthy cells. Both T cells and antibody-making B cells in patients reacted to these fragments, known as neoantigens, as if they were foreign threats. The researchers studied blood from 34 lupus patients and say the finding could reshape how scientists think about autoimmune disease, though they caution that clinical trials are still needed to prove these fragments drive the disease.
