IGFBP2 and Anxiety: Interestingly, a recent study revealed that Igfbp2 in BLA astrocytes is crucial for fear memory expression, whereas the knockdown of Igfbp2 led to significant deficits in fear memory without affecting its acquisition.[31] Furthermore, the open field test revealed no alterations following the deletion of Igfbp2 in BLA astrocytes, suggesting that Igfbp2 knockdown specifically impacted fear memory processes without influencing general locomotor or anxiety‐related behaviors, which is consistent with our results.
