اكتشاف بروتين يعيق علاج السرطان بالخلايا التائية CAR T

اكتشف الباحثون بروتيناً جديداً يُعرف باسم NFIL3 قد يكون العائق الأكبر أمام فعالية علاج الخلايا التائية CAR T للسرطان. يؤدي هذا البروتين إلى إجهاد الخلايا المناعية وفقدان قوتها بمرور الوقت، ولكن تعطيله ساعد في الحفاظ على قوة الخلايا ومكافحتها للأورام بشكل أكثر فعالية في النماذج الحيوانية.

  • يوفر هذا الاكتشاف هدفاً علاجياً جديداً لتعزيز استدامة وفعالية العلاجات المناعية للسرطان من خلال منع إجهاد الخلايا التائية الهندسية.
  • A newly identified protein may be one of the biggest obstacles holding CAR T-cell therapy back. Researchers found that NFIL3 causes these engineered immune cells to become exhausted and lose their cancer-fighting power over time. When NFIL3 was disabled, the cells remained stronger for longer and controlled tumors more effectively in animal models.

Why middle age is becoming a breaking point in the U.S.

A new international study finds that middle-aged Americans are lonelier, more depressed, and experiencing worse memory and health than earlier generations. Researchers say growing financial strain, weaker social supports, and chronic stress may explain why the U.S. is falling behind other wealthy nations.

Scientists mapped every neural connection in a fruit fly and found a surprise

A groundbreaking new connectome maps every neural connection in an adult fruit fly’s central nervous system, creating an unprecedented view of how the brain and body work together. The findings suggest that complex behaviors emerge from distributed local circuits rather than a single central controller, offering new clues about intelligence, movement, and brain function.
