Anybody a biology buff? I need some info about the autoimmune response.

[Guest guest]

I have a degree in biology but since I have not used this degree in the

least I am rusty on my knowledge. I have a question about the way in

which our meds interupt or circumvent the immune response. I have

recently been put on Orencia which I believe combats the T cells

themselves. I'm thoroughly confused. Is this med sapossed to supress

the antigen-presenting genes or inhibit the production of T-cells? I

read my booklet but it doesn't even go into depth about the process.

Also, is the antigen-presenting gene a macrophage that detects synovial

fluid? I know this sounds dumb, but I really wish someone can explain

this to me so I will better prepared to ask questions at the doc's

office. Help me out RN's!!!!Please!!
