The allergens associated with a cherry allergy are called Pru av 1, Pru av 2, Pru av 3 and Pru av 7.
Most people suffering from this allergy are thought to be sensitised to the protein Pru av 1, which is similar in shape to Bet v 1
which is a protein found in birch pollen. This can cause cross reactions with other fruit.
Pru av 2 is a thaumatin protein, this is made by plants to inhibit fungal growth.
Pru av 3 is a lipid transfer protein (LTP)
, more severe reactions to cherry are thought to be caused by these proteins.
Pru av 4 is a profilin protein
, these proteins are considered to be panallergens and can cause issues over many groups of foods.
Pru av 7 is a gibberellin regulated protein. Gibberellins are plant hormones associated with growth and development.
You may have Pollen-Food Allergy Syndrome
if you suffer from cherry allergy with oral allergy symptoms to 3 or more of the foods mentioned in cross reactivity section.
Allergy to cherry is sometimes linked to Celery-Mugwort-Spice Syndrome
as the sensitising allergen is a profilin protein called Art v 4, these proteins are also sometimes also called Bet v 2 proteins.
There is a link between cherry and Latex Food Syndrome
. The plant involved in latex allergy Hevea brasiliensis
, the rubber tree plant, has an allergen called Hev b 8 which is a profilin protein. Those very sensitised to latex may have a contact allergic reaction from other foods or plants containing profilin proteins, there is less evidence of this than sensitisation to other latex linked proteins like hevein and chitinases.
You may be suffering from LTP Syndrome
if you suffer allergic reactions from eating 3 or more foods mentioned in the cross reactivity section below.
If sensitised to alder tree pollen you may have Pollen Food Allergy Syndrome and may also react to apple, peach, pear, parsley, celery, almonds and hazelnuts.
If sensitised to birch tree pollen you may have Pollen Food Allergy Syndrome and may also react to kiwi, pear, peach, plum, nectarine, apricots, apple, tomato, celery, carrot, potato, parsnip, pepper, dill, cumin, peas, coriander, fennel, hazelnut, walnut, almonds, peanuts, lentils and beans.
Common foods involved in LTP allergy include kiwi, strawberries, sunflower seeds, walnut, apple, mulberry, banana, pea, apricot, cherry, plum, almond, peach pomegranate, raspberry, tomato, grape, celery, peanut, asparagus, cabbage, broccoli, chestnut, lemon, tangerine, orange, hazelnut, lettuce, lentils, lupin, green bean, pear, mustard, wheat and maize.
Other foods containing thaumatin proteins are kiwi, chilli, peppers, apple, banana, cherry and peach.
Other foods containing plant profilins are carrot, kiwi, pineapple, celery, peanut, chilli, watermelon, orange, hazelnut, melon, strawberry, soya, barley, walnut, lychee, lupin, apple, banana, date, cherry, almond, peach, pear, mustard, tomato, aubergine and wheat.
Gibberellin regulated proteins are also found in chilli, oranges, apricots, peach and pomegranate.
