Faith love (or anyone)
Im confused here. This is a quote from one of the links from LEF. (I think it is one of the original ones you posted)
" What most doctors don't know is that T-lymphocyte suppressor cells have the H2 receptor. By blocking this receptor (using an H2 receptor antagonist such as Tagamet), the immune system can be temporarily
turned up to help combat certain cancers and herpes viral infections."
I understood this to mean that this is allowing T cells to stay more active and able to go after virus' and such. It ramps up T cells because the T suppressor cells are being blocked and more T cells are out staying around fighting the good fight. The articles do talk about other ways it is an immune modulator but it mainly is an immune stimulant.
So, how are others interpreting this information?

When I read that article, I looked up "T-suppressor cells" and was directed to this passage on Wikipedia:
http://en.wikipedia.org/wiki/Regulatory_T_cell
"T regulatory cells are a component of the immune system that suppress immune responses of other cells. This is an important "self-check" built into the immune system to prevent excessive reactions. Regulatory T cells come in many forms, including those that express the CD8 transmembrane glycoprotein (CD8+ T cells), those that express CD4, CD25 and Foxp3 (CD4+CD25+ regulatory T cells or "Tregs") and other T cell types that have suppressive function. These cells are involved in shutting down immune responses after they have successfully tackled invading organisms, and also in regulating immune responses that may potentially attack one's own tissues (autoimmunity)."
I personally have too many T-cells, but most specifically, "CD8+ excess." They even checked how my CD8 functions with other components of my immune system, but that's way out of my scope of knowledge. If I am suppressing their "overreaction" to a virus, the rest of my immune system can get a handle on the infection without causing the full-blown inflammatory response and flu-like illness that you see in shingles, HSV, chronic EBV, etc. So (in my case), by suppressing ONE function of the immune system, you're thus ENHANCING the other components of the immune system so they can work together properly. Obviously you don't want to completely knock out your CD3, CD4, etc. -- you wouldn't have any immune system at all. AIDS patients have low CD3, CD4. The lower the number, the faster that person dies because they're left wide open for infection. My CD3, CD4 are elevated. From what I understand from my Immunologist, my T-cells kinda run around all crazy, waking up latent viruses because they can't "turn off" their inflammatory response and don't know when to quit. They DO eventually quit because so far they haven't attacked my organs or my brain and spinal cord, ruling out Lupus and MS. They are just dysregulated, which is the "immune dysfunction" part of CFIDS. So that is why cimetidine works as an immunomodulator in my case. It REGULATES the immune system so it can "turn off" the attack when the virus is under control, and it can fight off "invaders" without wreaking havoc and reactivating other latent viruses. That was my interpretation. I think if you already have normal T-cells and aren't experiencing the reactivation of latent infections with an exaggerated inflammatory response, cimetidine may work in OTHER ways for you -- it says it works by many different mechanisms. But unfortunately, I only know how it has helped me.
Notice I've said that the inflammatory response is slowed or controlled by whatever mechanism with cimetidine, not that I am suppressing my immune system's ability to fight off infection. I also want to mention for anyone else reading, please don't confuse my use of cimetidine with my use of steroids. Those were for 2 very different illnesses, and work in very different ways. I wasn't making recommendations for immunosuppressants by any means. I was just saying that I, personally, feel better when that inflammatory response is suppressed, which explains how my situation is unique. My methods of treatment will vary widely from those of you with immunodeficiency. My hospital participated in the XMRV study with WPI, so my doctors check for things that other doctors may not look into. The tests that were performed on my immune system and in hemodynamics aren't available in all labs or hospitals, so my course of treatment may be very different than someone who's seeing a naturopath, for instance. I just hope we're onto something here.
