Allergen,Individual-Tree pollen Mulberry Shahtoot (Morus alba)

Mulberry (Morus alba) is a small to mid-sized tree belonging to the genus Morus of the family Moraceae. It is generally found in areas with a subtropical or mild temperate climate and primarily cultivated worldwide to raise silkworms.

Mulberry pollen is considered a significant contributor to allergic pollen in the atmosphere. Exposure to its pollen may trigger symptoms like allergic rhinitis, allergic rhino-conjunctivitis, asthma, and, in some rare instances, contact dermatitis in sensitive patients. A cobalamin-independent methionine synthase protein, Mor a 2, has been detected as a significant novel allergen from mulberry pollen. Studies have also detected other allergenic proteins such as profilin, nsLTP (non-specific lipid transfer protein), a ubiquitin-like protein, and a cystatin-like protein from mulberry pollen extract. Significant cross-reactivity between mulberry pollen and other members of the Moraceae family, such as paper mulberry, breadfruit, fig-trees, and jackfruit, has been demonstrated. Cross-reactivity has also been reported with grass pollen and other tree pollens such as olive and alder.

An allergy to Mulberry Shahtoot (Morus alba) triggers a reaction in an individual's immune system. The body views certain substances as toxic and produces IgE antibodies to these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.
