Immune cells commit suicide to prevent allergy

 These antibodies, present in small quantities, are the most powerful “weapons” in the immune system and can trigger extremely violent immune reactions or immediate allergies (asthma, urticaria, allergic shock) as soon as their levels rise, even slightly. These findings, published online in Cell reports on 12 February 2015, thus elucidate how our bodies restrict the production of IgE in order to prevent an allergic reaction.

2Immunoglobulins, or antibodies, are proteins secreted by type B lymphocytes in reaction to introduction into an organism of a foreign substance (antigen).
