CUHK study identifies 11 allergens in crabs for precision diagnosis of allergy and discovers a new allergen for king crab, which is not a “true crab”
28.07.2025
The paediatric allergy team at The Chinese University of Hong Kong (CUHK)’s Faculty of Medicine (CU Medicine) analysed the six widely consumed edible crab species with 64 serum samples from crab-allergic patients, and found 11 crab allergens with differential epitope homologies and allergenicity. King crab is not a true crab, and the team also revealed that it has a distinct allergen of its own, which is not found in any other edible crab species. These findings will help promote accurate diagnosis of shellfish allergies and appropriate food avoidance, improving patients’ nutritional intake and quality of life. The study has been published in the authoritative international allergy journal Allergy and was presented at the 2025 Annual Meeting of the American Academy of Allergy, Asthma & Immunology (AAAAI) and Academy of Allergy and Clinical Immunology (EAACI) Congress 2025.
CUHK in Touch | Taking a bite out of shrimp allergy
12.06.2023
A new study led by Professor Leung hopes to change that by identifying the individual allergens, with the hope of developing more accurate diagnostics that can help to address the condition. It looked at 85 people with shrimp allergy, defined as having experienced immediate allergic reactions to eating shrimp at least twice within the past five years, and identified 11 allergens in shrimp. The majority of people, who experience relatively mild symptoms such as hives or swollen lips, are only allergic to one or two of the allergens, says the professor, but patients with moderate to severe reactions tend to react to a lot of them.
CUHK in Touch | Fighting allergies: CUHK unravels the genome profile of the American cockroach
17.03.2023
A team led by Professor Stephen Tsui Kwok-wing from CUHK Medicine’s School of Biomedical Sciences has produced the world’s most comprehensive genome profile of the allergy-causing American cockroach, Periplaneta americana, identifying seven new allergens on top of the existing 13.
CUHK in Touch | New Blood Test Improves Diagnostic Accuracy for Shrimp Allergy
23.02.2022
A research team from The Chinese University of Hong Kong’s (CUHK) Faculty of Medicine (CU Medicine) has proven that the basophil activation test (BAT) on individual blood samples has a much higher diagnostic accuracy for shrimp allergy than conventional allergy tests.
HKIA - e-Newsletter (Spring 2021)
14.05.2021
A recent article from the United States...highlighted the perils of dining out for food-allergic individuals and advocates the formation of mitigation strategies that can ultimately reduce the occurrence of food-allergic reactions while dining out.... We would like to highlight some of the most common hidden allergens in dishes found in our local community. This would serve as an important educational material for food-allergic individuals and families, allergists and health care professionals as well as restaurant industry.
CU Medicine Studies Suggest Grass Carp as a Major Source of Fish Allergy in Hong Kong And Identify Novel Allergenic Marker Cten i 1 to Promote Accurate Diagnosis
17.12.2020
The Faculty of Medicine at The Chinese University of Hong Kong (CU Medicine) has conducted two researches to thoroughly study the characteristics of Chinese fish-allergic patients in Hong Kong. Results showed that grass carp is more of a leading cause of fish allergy than other species for children in Hong Kong. The research team has also discovered a new allergenic marker from grass carp parvalbumin registered as Cten i 1 in the World Health Organisation and the International Union of Immunological Societies allergen database for diagnosis....
