اكتشاف جديد قد يقود إلى تطوير علاجات جديدة لمرض الزهايمر

ما يعرفه ريفو عن الخبر

اكتشف باحثون أن الحاجز الدموي الدماغي يعمل كواجهة ذكية تستخلص البروتينات المناسبة من الدم وتوصلها لخلايا الدماغ.
أظهرت الدراسة أن نقص وصول بروتين معين من الكبد إلى الدماغ يساهم في تآكل الروابط العصبية وظهور علامات مرض ألزهايمر.
أدى تعويض نقص هذا البروتين في فئران معدلة وراثيا إلى تراجع ظهور علامات المرض وتراجع تآكل الروابط العصبية.
يفتح هذا الاكتشاف الباب لتطوير علاجات لمرض ألزهايمر من خارج الدماغ عبر تعويض المواد التي يحتاجها المخ.

من خلال دراسة حديثة توصل باحثون إلى اكتشاف مذهل قد يساهم في تطوير علاجات جديدة لمرض ألزهايمر. فما الدور الذي تلعبه بروتينات الجسم في الحفاظ على الخلايا العصبية؟
