الأربعون والستون… محطتان حاسمتان في شيخوخة جهازك المناعي

ما يعرفه ريفو عن الخبر

يشيخ الجهاز المناعي بوتيرة أسرع عند بلوغ سن الأربعين ثم مرة أخرى عند سن الستين.
تظهر الدراسة اختلافات في سلوك الخلايا التائية والجينات المتحكمة بها عند هاتين المرحلتين.
تتمتع النساء بنشاط مناعي أكبر من الرجال مما يجعلهن أكثر عرضة لاضطرابات المناعة الذاتية.
يواجه الرجال تراجعاً أكبر في كفاءة الخلايا التائية مع تقدم العمر مما يزيدهم عرضة للعدوى.

كشفت دراسة جديدة أن جهازنا المناعي قد يشيخ بوتيرة أسرع عند بلوغنا سن الأربعين ثم مرة أخرى عند الستين
