This increases the molecular space the D3 A-ring can sample. The addition of the 25-OH and 1-OH groups, D3, adds H-bonding character to the molecule. It is these features of the 1,25D 3 molecule, in addition to the innate flexible of the side-chain atoms, which determine what proteins 1,25D 3 will bind to and perhaps more importantly the strength and dynamics of the interaction(s). The nuclear vitamin D receptor (VDR) is an intracellular protein that binds with very strong affinity to 1,25D 3 . In binding to the VDR, 1,25D 3 can directly regulate gene transcription and lipid signaling and the activity and/or localization of enzymes and ion channels. This chapter reviews how the dynamic interactions between 1,25D 3 and the VDR can regulate the pluripotent cellular functions that have been associated with the two molecules.

The inflammation is driven by stimulation of macrophages by aggregated superoxide dismutase 1 (SOD1) through caspase1, interleukin 1 (IL1), IL6 and chemokine signaling. Inflammatory gene activation is inhibited in vitro by tocilizumab, a humanized antibody to IL6 receptor (IL6R). Tocilizumab inhibits global interleukin-6 (IL6) signaling, a key mechanism in chronic rheumatoid disorders. Here we studied in vivo baseline inflammatory gene transcription in peripheral blood mononuclear cells (PBMCs) of 10 sALS patients, and the effects of tocilizumab (Actemra R) infusions. At baseline, one half of ALS subjects had strong inflammatory activation (Group 1) (8 genes up regulated >4-fold, P<0.05 vs. controls) and the other half (Group 2) had weak activation. All patients showed greater than four-fold up regulation of MMP1, CCL7, CCL13 and CCL24. Tocilizumab infusions i...

We tested two immune modulators in peripheral blood mononuclear cells (PBMCs) of AD patients and controls: 1 ,25(OH)2-vitamin D3 (1,25D3) and resolvin D1 (RvD1). Both 1,25D3 and RvD1 improved phagocytosis of FAM-A by AD macrophages and inhibited fibrillar A -induced apoptosis. The action of 1,25D3 depended on the nuclear vitamin D and the protein disulfide isomerase A3 receptors, whereas RvD1 required the chemokine receptor, GPR32. The activities of 1,25D3 and RvD1 commonly required intracellular calcium, MEK1/2, PKA, and PI3K signaling; however, the effect of RvD1 was more sensitive to pertussis toxin. In this case study, the AD patients: a) showed significant transcriptional up regulation of IL1RN, ITGB2, and NF B; and b) rev...

Decreased exposure to sunlight and decreased consumption of fish, fruits, and vegetables, are two epidemiological factors that appear to be related to the pandemic of AD. In addition to replacing simple with complex carbohydrates and avoiding saturated fat, two nutritional components, vitamin D (acting through the endogenous hormonal form 1α,25 dihydroxyvitamin D, 1,25D) and docosahexaenoic acid (DHA) (acting through the docosanoid lipidic modulators resolvins and neuroprotectins) have high potential for prevention of Alzheimer disease. 1,25D is a neuroprotective, it acts both directly and indirectly in neurons by improving the clearance of amyloid-beta by macrophages/microglia. Resolvins and neuroprotectins inhibit amyloidogenic processing of amyloid-precursor protein, inflammatory cytokines, and apoptosis. It is likely that the increased consumptio...

The key amino acids and structural requirements governing VDR binding to nuclear coactivators (NCoA) are well defined. Yet very little is understood about the internal changes in amino acid flexibility underpinning the control of ligand affinity, helix 12 conformation and function. Herein, we use molecular dynamics (MD) to study how the backbone and side-chain flexibility of the VDR differs when a) complexed to 1α,25(OH)2-vitamin D3 (1,25D3, agonist) and (23S),25-dehydro-1α(OH)-vitamin D3-26,23-lactone (MK, antagonist); b) residues that form hydrogen bonds with the C25-OH (H305 and H397) of 1,25D3 are mutated to phenylalanine; c) helix 12 conformation is changed and ligand is removed; and d) x-ray ...

In post-mortem ALS spinal cords, 19.8 ± 4.8 % motor neurons, including caspase-negative and caspase-positive neurons, were ingested by IL-6- and TNF-α-positive macrophages. In ALS macrophages, in vitro aggregated superoxide dismutase-1 (SOD-1) stimulated in ALS macrophages expression of inflammatory cytokines, including IL-1β, IL-6, and TNF-α, through activation of cyclooxy-genase-2 (COX-2) and caspase-1. The lipid mediator resolvin D1 (RvD1) inhibited IL-6 and TNF-α production in ALS macrophages with 1,100 times greater potency than its parent molecule docosahexaenoic acid. ALS peripheral blood mononuclear cells (PBMCs) showed increased transcription of inflammatory cytokines and chemokines at baseline and after stimulation by aggregated wild-type SOD-1, and these cytokines were down regulated by RvD1.

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 not by Type II macrophages. Here, we define the following intracellular mechanisms regulated by 1,25D3 that are associated with recovery of phagocytosis and consistent with the selectivity of BDC: 1) 1,25D3 potentiates a 4,4-diisothiocyanostilbene-2,2-disulfonic acid-sensitive chloride channel (i.e., ClC-3) currents in both Type I and II AD macrophages, but curcumin only potentiates the currents in Type I cells; 2) 1,25D3 is particularly effective in upregulating Cl...

There are already successes, as noted by 1alpha,25(OH)2D3 (Roche, and Abbott) for renal osteodystrophy and osteoporosis and 1alpha(OH)D3 (Leo, Chugai, Teijin) for renal osteodystrophy and (in Japan) osteoporosis, 1alpha,24(OH)2-24-cyclopropyl-D3 (Dovonex) and 1alpha,24(OH)2D3 (Teijin) for psoriasis, and 19-nor-1alpha,25(OH)2D2 (Abbott) for renal osteodystrophy, as well as drugs under active development. Yet there are still many important and challenging drug development frontiers, particularly in the area of cancer treatment and immune system disorders where exploration is only in the initial early stages. In addition, the application of vitamin D-related drugs in neurology and brain pathology should not be overlooked. It is to be hoped that the cellular and molecular basis for the vexing problem of analog-induced h...

Increased serum levels of IL6 and IL17A have been detected in sporadic ALS (sALS) patients when compared to healthy controls. Herein we investigate, in peripheral blood mononuclear cells (PBMCs), the baseline transcription of genes associated with inflammation in sALS and control subjects and the impact of the IL6 receptor (IL6R) antibody (tocilizumab) on the transcription and/or secretion of inflammation factors (e.g. cytokines) stimulated by the apo-G37R superoxide dismutase (SOD1) mutant. At baseline, PBMCs of four sALS patients (Group 1) showed significantly increased expression of TLR2 and CD14; ALOX5, PTGS2 and MMP1; IL1α, IL1β, IL6, IL36G, IL8 and TNF; CCL3, CCL20, CXCL2, CXCL3 and CXCL5. In four other sALS patients (Group 2), most of the genes just mentioned were expressed ...
