Yes, glucocorticoid receptors transrepress nf-kb in places like brain and genitals which are causing inflammatory proliferation and reduced neurotransmitter or nerve (NO, acetylcholine, NOR, ATP) signalling. You will find everyone with PFS in a constant state of inflammation and allergy. Look on the underside of the upper eyelids and you will most probably see papillary conjunctivitis. Shutting down the immune response for a short time may stop the whole process, which is the idea behind water fasting for example, and the reason how most recovery stories come into play, strong and short immunosuppression that breaks the cycle.
Many PFS people including myself also continue maintaining their hair as if they are still on finasteride. This is because GCR transcribe PGD2 receptors which causes MPB. PGD2 is also involved in superficial skin sensation.
That’s my theory.
