Cytokines involved in anaphylaxis
WebCytokines play a key role in coordinating antimicrobial effector cells and providing regulatory signals that direct, amplify, and resolve the immune response. Cytokines have short half-lives,... WebShocks which also include cardiogenic shock, hypovolemic shock and anaphylactic shocks are considered to be medical emergencies because of the rapid and systemic impact on the body. Anaphylactic shock occurs when the body’s antibody-antigen response is triggered by something the person is allergic to.
