بكتيريا خفية داخل الأورام… كيف تجعل السرطان أصعب علاجاً؟

ما يعرفه ريفو عن الخبر

تساعد البكتيريا المختبئة داخل الأورام الخلايا السرطانية على مقاومة العلاج عبر تعطيل الأدوية أو إضعاف الاستجابة المناعية.
يرتبط ارتفاع كمية البكتيريا في أورام الرأس والعنق ببيئة مناعية تساعد الورم على الإفلات من العلاج المناعي.
تستطيع بكتيريا معينة في أورام البنكرياس تحويل دواء العلاج الكيميائي إلى مادة غير فعالة بواسطة إنزيم تنتجه.
يستهدف العلماء حالياً طرقاً لتعطيل البكتيريا بدقة لتحسين فاعلية العلاج مع الحفاظ على الميكروبات المفيدة.

تكشف أبحاث حديثة عن أن بكتيريا داخل بعض الأورام قد تعطّل الأدوية وتضعف المناعة؛ مما يساعد السرطان على مقاومة العلاج، ويفتح مسارات بحثية جديدة لتحسين الاستجابة.
