Histamine 180-189 immunoglobulin heavy constant epsilon Homo sapiens 167-170 75852-2 1978 In accordance with previous hypothesis and circumstantial evidence, anti-IgE challenge led to a significant fall in the cyclic AMP level which preceded histamine release. Histamine 152-161 immunoglobulin heavy constant epsilon Homo sapiens 73-76
