Auto desensitization

Blackley found already in 1873 an interesting explanation of the “no allergy in farming children” effect by referring to some kind of auto desensitization in this particular environment – e.g. the high pollen and LPS exposure.
Do you know that a commercial allergen preparation used for desensitization already includes a LPS derivate, 3-o-desacyl-4′ monophosphoryl lipid A as an adjuvant? It is believed to push the pollen reaction into a IL12 – IFNg – Th1 pathway. This therapeutic approach already perfectly fits the early explanation of Blackley.
When will the allergy farming lobby ultimately close their files?

Pathway to nowhere

I love pathway diagrams since I mounted the famous Biochemical Pathways of Boehringer in my bachelor flat. As far as complex disease genetics is concerned with many disease genes, an integration into a pathway context becomes critical. There are many attempts to extract this information from the literature and many companies that offer highly curated information (Biomax, Ariadne Genomics, Genomatix to name a few). Academia relies mainly on KEGG, the Kyoto encyclopedia of genes and genomes or Biocarta. Last week another pathway server appeared that is curated by the NCI and Nature magazine. Let’s have a look – I am currently working on Affymetrix 500K SNP annotation, yea, yea.
