(Phys.org) -- Allergy to pollen of common ragweed is increasingly affecting patients and is second only to grass pollen in terms of incidence in the general population of many European countries. An Italian team led by Giovanni Appendino and Orazio Taglialatela-Scafati has now taken the first steps to investigate the phytochemical profile of the European population of A. artemisiifolia and studied its activation of TRPA1, a major player in the induction of airways inflammatory reactions. As the scientists report in the European Journal of Organic Chemistry, their findings help to better understand the increasing problem of sensitization to Ambrosia pollen.
