Does HLA- DR7 bind galactose and blood type antigen binders? ???

The intestine, skin  pancreas, and heart express blood antigen groups

Blood group antigens are proteins with galactose on them

norvovirus binds blood type antigens (is this how it is spread by touch?) does it have HLA-DR7?

HLA-DR7 induced in lupus with chlorpromazine?
https://www.ncbi.nlm.nih.gov/pubmed/9451597

Chlorpromazine binds to the outside of e.coli and salmonella and inhibits them. Is it binding the part of the bacteria that binds the galactose of the blood antigen?

only the galactosylated form of dopamine enters the brain
https://www.ncbi.nlm.nih.gov/pubmed/18164552

Chlorpromazine binds the brain's dopamine receptor.....where the galactose would bind?

Is HLA-DR7 a galactose protein mailbox?
