Is HLA-DRw7 a steroid linked mailbox?

HLA-DRw7 and steroid responsive nephrotic syndrome

Nephrotic syndrome is when the kidneys leak large amounts of proteins

note that cortisone is a type of steroid and that i had hypothesized earlier that spirochete infections cause high levels of cortisone (if not secrete it themselves)

Bell's palsy I had linked to the flu and spirochetes

HLA-DR2 and HLA-DR4 are linked to the flu viruses

HLA-DR W6 and HLA-DR W7....are these the spirochetes? 

could the HLA-DRw7 be the cortisone part? I had previously linked HLA-Cw3 to cortisone

How does this stuff link together?

could it be that in the kidney the steroids are processed in the cytosol while other cell types has the steroids processed in the ER (hla-c is for the endoplasmic reticulum)
