Abstract: Brain clearance of amyloid-β (Aβ42) by innate immune cells is necessary for maintenance of normal brain function. Phagocytosis of soluble Aβ42 by Alzheimer's disease (AD) macrophages is defective, recovered in all "Type I and Type II" AD patients by 1α,25(OH)2-vitamin D3 (1,25D3) and blocked by the nuclear vitamin D receptor (VDR) antagonist (23S)-25-dehydro-1α(OH)-vitamin D3-26,23-lactone (MK). Bisdemethoxycurcumin (BDC) is a VDR ligand and additive with 1,25D3 in promoting Aβ42 phagocytosis by Type I, but no…
