1 Inhibition of IgE and compound 48/80-induced histamine release by lectins. Histamine immunoglobulin heavy constant epsilon Homo sapiens
2 In addition, histamine release in an IgE-mediated and a compound 48/80-mediated reaction was inhibited in cells which had been pretreated with these lectins. Histamine immunoglobulin heavy constant epsilon Homo sapiens
3 However, the lectin-induced histamine release and the lectin-induced inhibition of subsequent IgE-mediated histamine release could be dissociated: thus L-rhamnose, a hexose not ordinarily found on mammalian cell membranes, a specifically inhibited histamine release which was caused by the lectin from R. communis without affecting the inhibition of IgE-mediated histamine release. Histamine immunoglobulin heavy constant epsilon Homo sapiens

Histamine immunoglobulin heavy constant epsilon Homo sapiens
6 Conversely, D-fucose, which also is not a constituent of cell membrane glycolipids or glycoproteins prevented the inhibition of IgE-mediated histamine release by this lectin without affecting the lectin-induced histamine release. Histamine immunoglobulin heavy constant epsilon Homo sapiens
7 Furthermore, the nominally galactose-specific lectins from Sophora japonica and Ulex europeus inhibited IgE-mediated histamine release while causing little if any histamine release themselves. Histamine immunoglobulin heavy constant epsilon Homo sapiens
