Pollen grains are a common allergen that can trigger allergic reactions in some people. Pollen allergens are proteins found on the surface of pollen grains and are responsible for triggering an immune response in sensitive individuals.
The main allergens in pollen grains are:
1. Amb a 1 (short ragweed)
2. Lol p 1 (rye grass)
3. Bet v 1 (birch)
4. Ole e 1 (olive tree)
5. Ced r 1 (cedar)
When pollen grains enter the body, they can trigger an allergic response, leading to symptoms such as:
– Congestion
– Sneezing
– Runny nose
– Itchy eyes
– Coughing
– Skin rashes
In severe cases, pollen allergy can lead to anaphylaxis, a life-threatening condition that requires immediate medical attention.
Pollen allergens are highly cross-reactive, meaning that individuals allergic to one type of pollen are likely to be allergic to other types of pollen as well. This is known as cross-reactivity or pan-allergenicity.
