علماء أمريكيون : اكتشاف طريقة جديدة لمعالجة أمراض السرطان المستعصية


اكتشف علماء أمريكيون طريقة مبتكرة تنشط الجهاز المناعي وتقضي على أكثر الأورام السرطانية عدائية ومقاومة للعلاج.
وأوضح بيان العلماء المنشور في مجلة “MedicalXpress” الطريقة الجديدة التي استطاع فيها علماء جامعة سينسيناتي تنشيط الخلايا المناعية وتوجيهها لمكافحة أمراض السرطان.
ووفقا للباحثين، فإن تراجع نشاط البروتينات الغشائية (جزيئات تسمح بالتعرف على الخلايا المحيطة وتحدد طريقة التعامل أو التفاعل معها) في قنوات البوتاسيوم “KCa3.1” يحدث بسبب روابط الأدينوزين التي تتراكم بشكل كبير في أنسجة الأورام.

ويعد الأدينوزين قامعا للجهاز المناعي، لكن الأخصائيين أثبتوا أن تثبيط الخلايا اللمفاوية يحدث بشكل غير مباشر من خلال بروتينات الغشاء وليس من خلال مسارات الإشارات. وهذا ما يمنع تغلغل الخلايا التائية القاتلة في الخلايا السرطانية للقضاء عليها.

ويعتقد العلماء أن العقار الذي يعيد عمل قنوات البوتاسيوم “KCa3.1″، يساعد بدوره الخلايا التائية القاتلة للوصول إلى خلايا الأورام على الرغم من غياب الأدينوزين. وستساعد هذه العملية مع العلاج المناعي في علاج أورام الخلايا اللمفاوية المستعصية.

    I want to express appreciation to you just for rescuing me from this problem. Right after browsing through the online world and obtaining opinions which were not beneficial, I believed my entire life was done. Living devoid of the approaches to the problems you have resolved by means of your good write-up is a critical case, and the ones that would have badly damaged my career if I hadn’t encountered your site. Your good capability and kindness in dealing with all the stuff was helpful. I am not sure what I would have done if I hadn’t come upon such a subject like this. I can at this time look forward to my future. Thank you so much for your high quality and effective guide. I will not think twice to recommend the blog to any individual who would need guidance on this situation.
