Introduction: Astrocytes are involved in Parkinson's disease (PD) where they could contribute to α-Synuclein pathology but also to neuroprotection via α-Synuclein clearance. The molecular signature underlying their dual role is still elusive. Given that vitamin D has been recently suggested to be protective in neurodegeneration, the aim of our study was to investigate astrocyte and neuron vitamin D pathway alterations and their correlation with α-Synuclein aggregates (ie, oligomers and fibrils) in human brain obtained from PD patients.
Methods: The expression of vitamin D pathway components CYP27B1, CYP24A1, and VDR was examined in brains obtained from PD patients (Braak stage 6; n = 9) and control subjects (n = 4). We also exploited proximity ligation assay to identified toxic α-Synuclein oligomers in human astrocytes.
Results: We found that vitamin D-activating enzyme CYP27B1 identified a subpopulation of astrocytes exclusively in PD patients. CYP27B1 positive astrocytes could display neuroprotective features as they sequester α-Synuclein oligomers and are associated with Lewy body negative neurons.
Conclusion: The presence of astrocytes distinguishes PD patients and suggests their contribution to protect neurons and to ameliorate neuropathological traits.
VitaminDWiki - CYP27B1 category listing contains:
The CYP27B1 gene activates Vitamin D in the Kidney, Skin, Lungs, Brain, Eyes Breasts etc.
Poor CYP27B1 is assocated with COVID, Miscarriage, Lupus, Alz, Parkinson, MSA, Rickets
CYtochrome P450 family 27 subfamily B member 1 = 25-Hydroxyvitamin D3 1-alpha-hydroxylase
60 items in CYP27B1 category 332 articles in the Genetics 513 articles in Vitamin D Receptor 176 articles in Vitamin D Binding Protein - CYP27B1 and other genes are less activated in seniors
- CYP27B causes many health problems – March 2020
- Every Parkinson’s brain had a poor CYP27B1 gene
What can be done if have a poor CYP27B1
- Larger doses of Vitamin D
- More Bio-available: Gut-friendly form, Topical form, taken with fatty meal, taken with evening meal
- Additional sources: UV
- Increase Vitamin D metabolism: additional Magnesium, Omega-3
- All cytochrome P450 enzymes require Mg++ as a cofactor
- Increase the amount of Vitamin D in the blood that gets to cells: increase activation of VDR
Vitamin D blood test misses CYP27B1 and other genes
VitaminDWiki - Other
- Gene mutations which restrict Vitamin D activation (CYP27B1) results in many health problems – March 2020
- Genes which regulate active vitamin D worsen with age – Oct 2016 -Including CYP27B1
- Does survival of the less fit mean less health (poor genes may be inherited)
VitaminDWiki - Vitamin D Receptor Gene probably more important
VitaminDWiki - Vitamin D Receptor category has
513 studies in Vitamin D Receptor category Vitamin D tests cannot detect Vitamin D Receptor (VDR) problems

A poor VDR restricts Vitamin D from getting in the cells47 studies in the Resveratrol category It appears that 30% of the population have a poor VDR (40% of the Obese )
Health problems include: Autoimmune (
Several diseases protect themselves by deactivating the Vitamin D receptor. Example: Breast Cancer

55 health problems associated with poor VDR
A poor VDR is associated with the risk of 55 health problems click here for details
The risk of 48 diseases at least double with poor VDR as of Jan 2023 click here for details
Some health problem, such as Breast Cancer reduce the VDRVDR at-home test $29 - results not easily understood in 2016
There are hints that you may have inherited a poor VDR
How to increase VDR activation
Compensate for poor VDR by increasing one or more:Increasing Increases 1) Vitamin D supplement Sun

and thus in the cells2) Magnesium Vitamin D in the blood
