Abstract: Vespa affinis (Asian wasp, Thai banded tiger wasp, or local name: Tor Hua Seua) causes the most frequent incidence of medically important Hymenoptera sting in South and Southeast Asia. However, data on the venom components attributable to the sting derived-clinical manifestations (local reactions, IgE mediated-anaphylaxis, or systemic envenomation) are lacking. This study provides the first set information on V. affinis venom proteome, allergenome, and IgE reactivity of individual venom components. From 2DE-gel based-proteomics, the venom revealed 93 protein spots, of which proteins in 51 spots could be identified and classified into three groups: typical venom components and structural and housekeeping proteins. Venom proteins in 32 spots reacted with serum IgE of wasp allergic patients. Major allergenic proteins that reacted to IgE of >50% of the wasp allergic patients included PLA1 (100%), arginine kinase (73%), heat shock 70 kDa protein (73.3%), venom allergen-5 (66.7%), enolase (66.7%), PLA1 magnifin (60%), glyceraldehyde-3- phosphate dehydrogenase (60%), hyaluronidase (53.3%), and fructose-bisphosphate aldolase (53.3%). The venom minor allergens were GB17876 transcript (40%), GB17291 transcript (20%), malic enzyme (13.3%), aconitate hydratase (6.7%), and phosphoglucomutase (6.7%). The information has diagnostic and clinical implications for future improvement of case diagnostic sensitivity and specificity, component-resolve diagnosis, and design of specific Hymenoptera venom immunotherapy. © 2014 American Chemical Society.
