Melbourne Pollen—a service on the University of Melbourne’s School of BioSciences that forecasts the extent of grass pollen and a number of other different varieties of pollen within the air—has been taking a look at what’s in Melbourne’s air for greater than 40 years. Mostly we’re searching for pollen however, lately, we have taken a deep dive to see what else is there.
Why are we doing this?
One motive is curiosity, and the opposite is to enhance our understanding of the hyperlink between pollen and allergic reactions.
Although we rely pollen, significantly grass pollen, individuals with hay fever and bronchial asthma aren’t truly delicate to the pollen itself, however to extraordinarily small molecules known as allergens which might be a part of the pollen grain. In somebody with an allergy, these allergens stimulate sure varieties of immune cells of their physique, and it is the molecules launched by these activated cells that set off signs of hay fever and bronchial asthma.
For the 2022 to 2023 pollen season, Melbourne Pollen has been working with the Department of Biochemistry and Pharmacology on the University of Melbourne, to see how a lot of a selected grass pollen allergen known as the group V allergen (pronounced group 5 allergen) is within the air, and whether or not the quantity of this allergen, per grass pollen grain, stays the identical or modifications over the season.
Our partnership consists of the Materials Characterization and Fabrication Platform (MCFP), which is utilizing its superior tools to establish what else is in our air.
