Scientists find ethnicity linked to antibodies“‘[I]t’s early days,’ emphasizes Watson, ‘but these findings could mean that past environmental exposures to certain pathogens caused DNA insertions or deletions in different ethnic groups, which could impact disease risk. Our results demonstrate that antibody studies need to take into account the ethnicity of DNA samples used.'”

  1. “Scientists find ethnicity linked to antibodies…”

    This is along the lines of something which has interested me for a number of years, which is the human leukocyte antigen (HLA) system [the name given to the major histocompatibility complex / MHC in humans].

    http://en.wikipedia.org/wiki/Human_leukocyte_antigen

    I have looked at HLA haplotypes as a means of tracking assymetric migrations by population groups in prehistory.

    In terms of ethnicity, the most frequent HLA haplotype in caucasians / people of European descent is A1-B8.

    http://en.wikipedia.org/wiki/HLA_A1-B8-DR3-DQ2

    This appears to have spread throughout Europe from refugia at the end of the Pleistocene.

    It confers susceptibility to several diseases/conditions.

  2. @luke – “Lubos Motl has a post on the paper that prompted this article, a post that I thought was even more fascinating than the paper itself.”

    cool. thanks!

    very interesting! this is something i know absolutely nothing about. have you ever written your ideas up anywhere? you’re welcome to do a guest post on the topic here if you like, if you don’t have a blog of your own (and aren’t interested in starting one). (^_^)

  4. Thank you Hbd Chick, that is a very kind offer. I don’t have a blog myself and don’t have plans to (even though I do have a wordpress account). I haven’t written my ideas up anywhere, however my interest was sparked by a molecular biologist who used to write on the usenet science newsgroups many years ago, who occasionally still corresponds with me. I have found HLA haplotypes a far better marker for tracking ancient human migrations than mtdna or Y dna, for a number of reasons. I am quite busy this week but I could write something to send over in a few days’ time. I might need a some guidelines though? My email is….

  5. The stuff about the shorter lives of stars is nothing shocking nor worth worrying about. 77 years is still a long enough lifespan. Its better to live a short but fun successful life than a long but boring miserable one.
