Astrocytes Remember: A New Layer of Immune Memory Uncovered

Astrocytes, traditionally non-immune cells within the central nervous system, possess the ability to develop an immune memory, responding more vigorously to subsequent immune challenges. This groundbreaking study reveals that through an epigenetic mechanism involving the enzymes p300 and ATP-citrate lyase (ACLY), astrocytes enhance their pro-inflammatory responses, a trait similar to the immune memory seen in adaptive immunity.

Unmasking Anosognosia: Revealing Hidden Brain Networks in Unawareness

Researchers identified specific brain network connections associated with anosognosia, a condition where patients are unaware of their neurological or psychiatric deficits. Using a technique called lesion network mapping, they identified separate networks linked to visual and motor anosognosia and a shared network responsible for awareness of these deficits. The shared network converged on the hippocampus and precuneus, both associated with memory.
