Anaphylactic shock is a severe allergic reaction involving multiple organs including the bronchial and cardiovascular system. Most anaphylactic mediators, like platelet-activating factor (PAF), histamine, and others, act through G protein-coupled receptors, which are linked to the heterotrimeric G proteins G(q)/G(11), G(12)/G(13), and G(i). The role of downstream signaling pathways activated by...

Anaphylactic Shock by Azodyes

Experiments are described which show that anaphylactic shock can be induced in animals sensitized with azoproteins by injecting them with azodyes containing the same azo components as the sensitizing antigen. The anaphylactic reactions are specific and occur with quantities of the dyes as small as fractions of milligrams.
