    Default Androstenone receptor?

    "There is

    some evidence published showing this chemical can modify the mood or hormone levels in humans," he said. "What we

    don't know is whether the receptor we found was in any way involved in this process."

    Default Androstenone and androstadienone receptor in the nasal epithelium

    http://www.ncbi.nlm.nih.gov/sites/en...ubmed_RVDocSum

    From the article:

    "Recent

    expression analysis shows that OR7D4 is selectively expressed in human nasal epithelium." Citation: Zhang, X. et al.

    Characterizing the expression of the human olfactory receptor gene family using a novel DNA microarray. Genome Biol.

    8, R86 (2007).

    Once again, there appears to be no support for the concept that human pheromones act through

    what appears to be a non-existent human VNO.

    IIRC, I read that the receptor

    forms differently in different people (same DNA but different end result... polymorphic or something), which they

    said is why some people perceieve the smell of -None differently. I think the same article said that up to about

    half of people can be "trained" to smell the scent after a while.

    I've certainly noticed this happening with

    me, I can notice -None much more easily than I could when I first started.

    Theoretically, exposure induces change in receptor expression via gene activation. The

    theory behind this is very difficult to grasp without some knowledge of the immune system (e.g., genetics), and its

    interaction with the neuroendocrine system. So most people might better understand the reductionist approach: the

    immune and olfactory systems function in similar ways to recognize what is like us, or is not like us. We can

    recognize a pig's smell as being like some of us, but hopefully not you or me. I am (half jokingly) concerned that

    you might be slowly learning that you may smell like a pig. But even pigs don't require a VNO to "know" one pig

    from another.

    I think this: "Theoretically, exposure induces change in receptor expression via gene activation."

    is cool
    Animals and humans... what complex and cool beings..

    Happy to learn you "got" the joke. If I can't have some fun with this stuff once in a

    while, I'll quit learning about it.
