Capsid, I was looking a bit further into the relationship between transfer factor and cytokines, and it's a bit hazy. Cytokines are, I believe, peptides, proteins or glycoproteins. The peculiarity of Wakefield's description of transfer factor is that he talks about "
RNA bases attached to small peptides". I don't know what that would make this, but as far as I know, cytokines don't have nucleic acids in them, do they?
My suspicion is that in the 1940s and 1950s, Lawrence was transferring cytokines (not identified or named then, as far as I know) between individuals, and wrongly assumed he had identified something antigen-specific. He believed he had found a way to transfer CMI between individuals and so apparently confer active CMI immunity to the second individual without actually exposing him to the antigen.
Am I right in saying that cytokines are however not antien-specific, therefore the idea that transferring cytokines from one individual to another would not confer CMI to a particular antigen on the second individual? So the whole idea is completely wrong?
As I said, I suspect Lawrence had noted some non-specific effect of transferring cytokines, and interpreted in wrongly. It seems as if he himself was regarded as a bit of a maverick even at that time, and nobody appears to have followed up on his research. It all petered out in the 1960s I think.
Then if looks as if it was rediscovered by quacks in the 1990s, possibly Fudenberg himself, though I haven't looked into that, and Wakefield has become attached to the people promoting the idea.
I can just imagine the conversations at the Royal Free when someone actually looked into the details of what was on these patent applications, and got the real immunologists to comment. I'd like to have been a fly on the wall. No wonder they washed their hands of the patents, as well as Wakefield.
So, if "transfer factor" is anything, it's cytokines. A crude extract, inevitably containing an awful lot of different molecules. Wakefield never seems to have attempted to isolate his alleged active ingredient. If the preparation also contains RNA fragments, that might explain his description of it as contaiing both RNA bases and peptides.
What do we know about cytokines?
Correct, what went wrong with that drug trial disaster was a "cytokine storm" caused by the antibodies that were injected into the volunteers. Again, that's a very different situation to what Wakefield was doing, but would the parents of autistic children be pleased to learn that the "transfer factor" Wakefield is giving is likely to be composed of the same cellular regulators as were responsible for that incident?
Capsid, do you have any thoughts on this?
