    Hormone have a great impact on the neuro-immune functions, probably sex steroid have a nice effect on protection like ADIOL

    The discovery that the steroid hormone ADIOL, (5-androsten-3Β-17Β-diol), a precursor of androgens and estrogens, modulates inflammation induced by microglia cells could eventually lead to new treatments for patients with neurodegenerative conditions in which inflammation plays a pathogenic role. In addition, levels of ADIOL in blood or other body fluids might be useful for predicting risk or responses to drugs that mimic its actions.

    Abstract

    Microglia and astrocytes play essential roles in the maintenance of homeostasis within the central nervous system, but mechanisms that control the magnitude and duration of responses to infection and injury remain poorly understood.

    Here, we provide evidence that 5-androsten-3β,17β-diol (ADIOL) functions as a selective modulator of estrogen receptor (ER)β to suppress inflammatory responses of microglia and astrocytes.

    ADIOL and a subset of synthetic ERβ-specific ligands, but not 17β-estradiol, mediate recruitment of CtBP corepressor complexes to AP-1-dependent promoters, thereby repressing genes that amplify inflammatory responses and activate Th17 T cells.

    Reduction of ADIOL or ERβ expression results in exaggerated inflammatory responses to TLR4 agonists.

    Conversely, the administration of ADIOL or synthetic ERβ-specific ligands that promote CtBP recruitment prevents experimental autoimmune encephalomyelitis in an ERβ-dependent manner.

    These findings provide evidence for an ADIOL/ERβ/CtBP-transrepression pathway that regulates inflammatory responses in microglia and can be targeted by selective ERβ modulators.

    Thanks for finding the reference article.
