Guest guest Posted March 30, 2005 Report Share Posted March 30, 2005 Hi Barb. Thanks for the feedback. Perhaps we can view suspressed Lymphocytes as part of the effect of having undergone chronic systemic inflammation? Regarding the model, I think perhaps I've misled you with the term lymphocyctes. I was thinking wider, perhaps even as wide to consider all active motile cells (leukocyctes): monocyctes, macrophages, dentritic, NKs, eosinophils, neutrophils, basophils, mast cells etc. Does this fit better?

Guest guest Posted March 30, 2005 Report Share Posted March 30, 2005 , do you have your file avail in a format other than powerpoint? i'd love to look at it, but don't have that program on the computer available to me. many thanks. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 30, 2005 Report Share Posted March 30, 2005 , they say the best solutions are sometimes the simplest solutions ...Could it be??? ..could this be the biggest breakthrough in unravelling the mysteries of infectious disease?....It makes perfect sense & as you know matches my history exactly...I didn't know introducing a pathogen has helped to kill cancers!! when you consider that it all falls into place ...You've already solved one deep mystery, explaining the chain reaction process of inflammation & how ARb's mop up that inflammation reducing the dependence on ARB's ...Add to that, the possibility that immune stimulants such as the cytokine Interleukin-2 .could prove to be the missing link ... To me it represents the best shot yet ...early days but , I feel privileged to receive the information ...thanks for being there... -----Original Message-----From: garyrsmith36 [mailto:gary.smith@...]Sent: 30 March 2005 12:13infections Subject: [infections] Hypothetical model for lymphocyctesHi.I've posted a file which I would like you guys to review.In this three way model I have considered three main functions for lymphocyctes: Wound clearance (Inflammation), Wound resolution (healing) and pathogen recognition/killing.The hypothesis is that dependent on their environment lymphocyctes are engaged towards achieving one of these three activities. Focus too far in any one direction leading to disease conditions.Although perhaps not a precise analogy you could consider so called TH2 diseases at the top 'hypersensitivity' and on the bottom left TH1.Glucocorticoids block inflammation mediators, but they also block IL-2, hence Cushing's syndrome on the bottom right.Pathogens promote inflammation (some TH1 diseases) in order to avoid effective immune response. Regarding colds/flu and their effects on people suffering from TH1 we could imagine that initially you would feel worse due to the additional inflammation that the cold/flu causes. Once your system has recognised the virus however you start to generate additional IL-2 which takes your lymphocyctes away from inflammation and towards the top.This model also helps to explain something that puzzled me regarding cancer and that early treatment with an infecting agent helped to kill the cancers.I may have to delete this file in a day or so.Best regards, .

Parasites, such certain forms marlaria, can induce TGF-Beta production, which then suppresses the TH1 response, and blocks the killing off of the parasites. Viruses, on the other hand, such as EBV, prevent cells from responding to TGF-Beta. TGF-Beta is important in bringing the TH1 response to a resolution, so without TGF-Beta, the TH1 response (and inflammation) continues, and the viruses survive.

Guest guest Posted March 31, 2005 Report Share Posted March 31, 2005 Hi Mark. A possibly unique attribute of the AT1 receptor is that it can stimulate the expression of TGF-b. (TGF-b as well as being produced by AT1 also circulates in the blood) TGF-b appears to play a significant role both in wound clearance and wound resolution phases. I would describe I think TGF-b as a key worker rather than a manager of inflammation and healing. In pathogen killing TGF-b plays a role too. In cancer for instance TGF-b is part of the bodies initial defense mechanisms to promote apoptosis in these faulty cells. Cancers seem to learn to avoid this and other control systems through genetic changes as a prerequisite for uncontrolled growth. I could see that certain virus's could also be able to distrupt this process but then there are a number of mechanisms for pathogen killing. I think when we talk about messengers at the level of TGF-b we have to careful to avoid absolutes since there is a very complex web of messages going on. TGF-b may cause events in some environments and in others it would contribute to something else. This is why I have been trying to look at the endgames and the big picture in trying to model what is going on. If I find the model doesn't fit then I'll puzzle over it again.

Guest guest Posted March 31, 2005 Report Share Posted March 31, 2005 Here is doc Kaisers: http://www.cat.cc.md.us/courses/bio141/lecguide/index.html You may well need to learn some basics first, elsewhere on the web. I had alot of trouble making sense of doc K's at first. Even when I started to dig it, I had to read every section over and over again. C Janeway's immunology text is often cited as a lucid introduction for college level bioscience students. I've only looked at it for a few min but saw at least one theory stated as fact. It has alot of diagrams and pics. I wasnt as impressed with it as I expected, but then I do have kinda a negative attitude about everything Not everything in doc K's and these books is 100% reliable. Even s " Fundamental Immunology " , at 1700 pp, yields significantly less knowledge than what you can get from really digging the journal lit on a particular topic. And of course, new knowledge accretes really fast. If you have any particular questions just ask, its no sweat for me to fire off an answer cause I got it all swirling around in my head already - will probably cost me all of 2 mintues.

Guest guest Posted April 1, 2005 Report Share Posted April 1, 2005 Thanks , Whew, that is a lot of reading. It will take me some time to plod through some of it. It does give me a little background info though.
