Your response actually relates much to the first article I referenced above. If inability to successfully produce cell ligand is the root issue, this might also imply that the intracellular receptors are not functioning properly either since this is where the ligangs bind to get signal. I would also imagine that if you try to restore those intracellular structures you run some risk of denaturing them so you will not be able to do any biochemical assay with the fixed cell? it sounds like a difficult task to increase or repair specificity of binding interactions after they have been regulated/altered. Are you aware of any successful treatments or cures in similar cases? Is this something that happens a lot in medicine?
I imagine that the reversing of inhibition of 5AR is very sensitive. I can’t remember who but someone on here used a bell curve analogy that was spot on in my mind.
