Common ragweed (Ambrosia artemisiifolia L.): Allergenicity and molecularcharacterisation of pollen after plant exposure to elevated NO2. Plant, Cell & Environment , DOI: 10.1111/pce.12601 ...

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. Surprisingly ...

Pollen of the common ragweed (Ambrosia artemisiifolia) has higher concentrations of allergen when the plant is exposed to NO2 exhaust gases, according to new findings. Pollen of the common ragweed ...

Therefore, B cells were either exposed to the main Ambrosia allergen Amb a 1, the pollen associated substance PPE1 or the total extract and a protein/allergen free fraction of the extract ...

Pollen allergies affect about 50 million people in the United States, and are the main cause of hay fever and other allergies. "After studies have already shown that Ambrosia growing along ...

In addition, the scientists observed that the pollen from NO2 treated plants have a significantly increased binding capacity to specific IgE antibodies* of individuals allergic to Ambrosia.

Total pollen values also are increasing year by year despite government efforts to eliminate Ambrosia. “Our pollen count suggests that this fight is not very successful,” Rodinkova said.
