Blаck widоw аnti-venоm is prоduced by injecting smаll amounts of the actual venom into horses. Several days after the first injection, the horse begins to produce antibodies against the venom. Later, more venom is injected to the animal, and exponentially more antibodies are quickly produced. These antibodies can be harvested from the blood and used to treat bite victims. The medication is rarely used, however, as it carries a risk of causing an allergic response in humans who react to the proteins from the horse. What cells are activated by the antibodies produced by the allergic response?
