Are eosinophilic nasal polyps a rich source of eotaxin , eotaxin-2 and eotaxin-3?
Our findings suggest, that all members of the eotaxin family are involved in the pathogenesis of nasal polyposis. The results are more likely indicative of a complex cooperation between all members of the eotaxin family than of a specific role in the development of eosinophilia and nasal polyposis.
The root transcriptional response to the Fe supply depends on the nature of chelating agents (WEHS, citrate and PS). The supply of Fe-citrate and Fe-PS showed not only a fast back regulation of molecular mechanisms modulated by Fe deficiency but also specific responses due to the uptake of the chelating molecule. Plants fed with Fe-WEHS did not show relevant changes in the root transcriptome with respect to the Fe-deficient plants, indicating that roots did not sense the restored cellular Fe accumulation.
