Why pollen makes you go AAHHH-CHOOO!!!
Pollen exposure can cause allergic airway inflammation. The role of antigenic pollen proteins in this allergy is well characterized, but the contribution of other constituents in pollen grains in this process is unknown.
In a new study appearing on August 1 in The Journal of Clinical Investigation, Sanjiv Sur and colleagues from University of Texas Medical Branch show that pollen grains and their extracts contain cell membrane-associated enzymes called NADPH oxidases. These pollen NADPH oxidases increase reactive oxygen species in the lung and other pro-inflammatory factors in the fluid lining the airways.
Removal of NADPH oxidase activity from the pollen inhibited allergic airway inflammation in sensitized mice. Thus, oxidative stress ge
