The terms CCD or CCDs describe protein-linked carbohydrate structures responsible for the phenomenon of cross-reactivity of sera from allergic patients towards a wide range of allergens from plants and insects. In serum-based allergy diagnosis, antibodies of the IgE class directed against CCDs therefore give the impression of polysensitization ...
In adults, up to 60% of all food allergic reactions are due to cross-reactions between foods and inhalative allergens. [4] OAS is a class II allergy where the body's immune system produces IgE antibodies against pollen; in OAS, these antibodies also bind to (or cross-react with) other structurally similar proteins found in botanically related ...
Cross-reactivity, in a general sense, is the reactivity of an observed agent which initiates reactions outside the main reaction expected. This has implications for any kind of test or assay , including diagnostic tests in medicine, and can be a cause of false positives .
Because the major carrot allergen, the protein Dauc c 1.0104, is cross-reactive with homologues in birch pollen (Bet v 1) and mugwort pollen (Art v 1), most carrot allergy sufferers are also allergic to pollen from these plants. [66] In India, carrots are used in a variety of ways, as salads or as vegetables added to spicy rice or dal dishes.
A severe allergic reaction may come with a hive-like rash, swelling and inflammation of the bite area and swelling around the eyes, the Mayo Clinic says. Bee and wasp stings What they look like:
Shellfish allergies are highly cross reactive, but its prevalence is much higher than that of fish allergy. Shellfish allergy is the leading cause of food allergy in U.S adults. [ 31 ] As of 2018 six allergens have been identified to prawn alone; along with crab, it is the major culprit of seafood anaphylaxis. [ 13 ]
