Just a thought to start with... Are you really interested in
researching something, or just making arguements about stuff you
obviously don't know about?!?? I'd like to think you're serious about
researching something, but I've my doubts...

It's quite obvious to me what they're talking about, and why they
named their antibodies the way they did. You'll agree that they named
the antibodies as such, correct? What happens if they've got more than
one antibody against an antigen? Give it the same name? I don't think
so... Ever done a fusion? If they'd made specific antibody, they'd
have give the antibody a name, and not give it the antigens name. They
would've said, "anti-ste" for example. It's just how things are done,
and it makes sense.

Additionally, you've ignored my other points about the
databases. There are no other instances of anything remotely like
"Human STE" as a yeast homologue. Not in nucleotide or protein
databases, nor in the literature. See below.

There are various data on leukocytes in the nasal mucosa. In fact,
there are conjectures about olfactory stimuli and neutrophil
accumulation in response to temporary ischemia there. Problem is,
there's nothing that suggests what you suppose. But you're right. No
one has specifically looked for antigen specific autoimmune T-cells
against vomeronasal antigens. But then, why would they?!?!

Your hypothesis is full of holes, and poorly stated.  What do you want,
anyway?!? What is this "Collected writings copyright" for? If you're
trying for a patent position, I'm afraid you've a ways to go...

So, to take your meaning, you think that some sort of immune imbalance
leads to an improper signaling event in/from the nasal mucosa? You've
got no reason to think so, and no mechanism. You started out by
postulating that there's other pathways for odour sensing/processing
than known ones, without any good (or bad) reason at all.

You've concocted an entire position out of thin air. See below.

Are you suggesting that you are in control of hundreds of thousands of
dollars for research?!?!!

The Internet already provides many useful functions, anyway. The real
conclusion is that you must form a prima facia case based on facts,
and not conjecture. The reasoning must be logical, the model must
explain the data and predict other untested outcomes, and hopefully be
testable. You've provided none of this. See below.

Good. Why don't you call them?

Did you know that in the French, ste is an abbriviation for a female
saint? I bet you didn't. Have you done a medline search for the
keyword ste? I know you haven't. I know because you'll find:

1. Armengol X; Estelrich J.
     Physical stability of different liposome compositions obtained by
     extrusion method.
   Journal of Microencapsulation, 1995 Sep-Oct, 12(5):525-35.
       (UI:  96093127)

which contains:

"DPPC:CHOL:stearylamine (STE)"

2. Iskhakova FKh; Esipova OV; Zvonkova EN.

     peptides].

       (UI:  96096913

which contains:

"compounds containing a Ste-Pro fragment"

3. Her C; Aksoy IA; Kimura S; Brandriff BF; Wasmuth JJ; Weinshilboum RM.

       (UI:  96079087)

Reference number 4 referred to a cell line called "STE".

And so on. There are, dare I say, many more "researchers and
reviewers" who are carelessly throwing STE around than there might at
first seem. There were 102 refs that came up in my search from
above. The great bulk of them had little to do with yeast. In fact,
crossing the above result with keyword yeast, yielded 8 cites. I think
you're flogging a dead horse here.

I simply pointed out that you base your assumptions on what your
friends do/say. If you want me to point out flaws in your other cites,
I'll do so. For example, you might start with how many genes are found
in the MHC region. Finding something there has become, dare I say,
almost routine? The fact that a gene lies close to another means
little by itself. All genes lie next to other genes. Besides which,
you've no link from any gene there, to your hypothesis.

Blanchard's data is that homosexuals with siblings often have male
older brothers. Wedekind had women smell T shirts (worn by males) and
rate them as pleasant or no, then compared with MHC. I'm afraid you've
got a long way to go before any reasonable person would take this as
significant support for your theory.

The other point in your original post was from WJ Turner, who proposes
that homosexuality in males might be X-linked. Neither does this
directly (or indirectly) support your theory.

>But thanks for making effort to address my hypothesis, including its

No problem. You've got some rethinking to do, as I see it. Perhaps
you'll post an updated model? And perhaps an explaination of what it
is you're after? (eg, personal interest, research proposal, class
assignment, etc.)

Later,

Aaron
