hevein


Also found in: Wikipedia.

hevein

(hē′vē-ĭn)
A protein allergen found in natural rubber latex that stimulates neutrophils to release oxygen radicals. Hevein is a lectin responsible for the IgE-mediated hypersensitivity response to latex products.

Four different rows of three different microtiter plates were coated in this pattern: wells A1, B1, C1, and D1 were coated with [T.sub.3]; the other eleven wells of each row (A2-A12, B2-B12, C2-C12, and D2-D12) were coated with roasted cashew, egg, seaweed, or latex hevein. Controls and inhibitors were then added as follows: 100 [micro]L of serum diluent to wells A1-A2, B1-B2, C1-C2, and D1-D2; 100 [micro]L of diluent containing 100 [micro]g of [T.sub.3] to wells A3, B3, C3, and D3; and 0.5-120 [micro]g of cashew, egg, seaweed, and latex hevein to, respectively, A4-A12, B4-B12, C4-C12, and D4-D12.
Using this monoclonal antibody against Tg resulted in a 3+ immune reaction with latex hevein (see Table 2).
Lectins have been classified into 12 different families based on their domain structures and phylogenetic analyses: ABA (Agaricus bisporus agglutinin), amaranthin, chitinase-related agglutinin (CRA), cyanovirin, Euonymus europaeus agglutinin (EEA), Galanthus nivalis agglutinin (GNA), hevein, jacalins, legume lectin, lysin motif (LysM), and nictaba and ricin B families (Jiang et al.
After leaving Apocalyptica in early 2000s, it seems Max unveiled his full potential - besides being a cellist in Finnish National Opera Orchestra, he became member of a multi genre metal band Hevein and a Finnish folk-pop band Tekija Tuntematon, whose music is based on Finnish poetry.
[4] Thirteen different hevein latex proteins have been recognised as allergens by the Allergen Nomenclature Subcommittee of the World Health Organization/International Union of Immunological Societies.
This class of chitinases contains a cysteinerich 40-amino-acid domain at the N-terminus, the chitin binding hevein domain, a hypervariable domain (which is a proline-rich hinge region), and a catalytic domain [98].
Demonstration by mass spectrometry that pseudo-hevien and hevein have ragged C-terminal sequences.
IgE epitope analysis of the hevein preprotein; a major latex allergen.
A recently identified 46/110-kd protein, is common among health care workers,[40] as is the hevein preprotein.
Of note, plant lectins can be divided into 12 different families, including ABA (Agaricus bisporus agglutinin), Amaranthin, CRA (chitinase-related agglutinin), Cyanovirin, EEA (Euonymus europaeus agglutinin), GNA (Galanthus nivalis agglutinin), Hevein, Jacalins, Legume lectin, LysM (lysin motif), Nictaba and Ricin_B families (Van Damme et al., 2008).
Four major lectin families, namely, the legume lectins, the chitin-binding lectins composed of hevein domains, the type2 ribosome-inactivating proteins and the monocot mannose-binding lectins comprise the majority of all currently known plant lectins (Van Damme et al., 1998a).
