abstract = {Neuroinflammation including interleukin
(IL)-12/IL-23-signaling is central to Alzheimer's disease
(AD) pathology. Inhibition of p40, a subunit of IL-12/IL-23,
attenuates pathology in AD-like mice; however, its signaling
mechanism and expression pattern remained elusive. Here we
show that IL-12 receptors are predominantly expressed in
neurons and oligodendrocytes in AD-like APPPS1 mice and in
patients with AD, whereas IL-23 receptor transcripts are
barely detectable. Consistently, deletion of the IL-12
receptor in neuroectodermal cells ameliorated AD pathology
in APPPS1 mice, whereas removal of IL-23 receptors had no
effect. Genetic ablation of IL-12 signaling alone reverted
the loss of mature oligodendrocytes, restored myelin
homeostasis, rescued the amyloid-β-dependent reduction of
parvalbumin-positive interneurons and restored
phagocytosis-related changes in microglia of APPPS1 mice.
Furthermore, IL-12 protein expression was increased in human
AD brains compared to healthy age-matched controls, and
human oligodendrocyte-like cells responded profoundly to
IL-12 stimulation. We conclude that oligodendroglial and
neuronal IL-12 signaling, but not IL-23 signaling, are key
in orchestrating AD-related neuroimmune crosstalk and that
IL-12 represents an attractive therapeutic target in AD.},
