BMAL1 and Alzheimer disease: Recently, it has also been found that the loss of Bmal1 from astrocytes does not interpret the increased plaque burden in whole‐brain Bmal1‐knockout mice, suggesting that the status of astrocyte activation in AD brains has complex effects; further studies are needed to explore its non‐Aβ‐associated contribution in AD (McKee et al., 2022).
