Description

The study shows PKA phosphorylates AnxA1 and this leads to neutrophil apoptosis, but the intermediate signaling cascade is not elucidated. Understanding this pathway is crucial for developing targeted anti-inflammatory therapeutics that could modulate neuroinflammation in neurodegenerative diseases.
