<unk>  is generally caused by either antibodies or immune cells that cause damage to the<unk>  ear. There are several theories that propose a cause of<unk> : *Bystander damage – Physical damage to the<unk>  ear may lead to cytokine release that signals for an immune response. This may be a component of the "attack/remission cycle" of Meniere's<unk> . *Cross-reactions – Accidental damage of the<unk>  ear by antibodies or T-cells that recognize an<unk>  ear antigen that is similar to a bacterial or viral antigen *Genetic factors – Predisposition to developing an<unk>  disorder based on genes<unk> ited *Intolerance – The immune system may not be aware of all the antigens present in the<unk>  ear until physical damage releases some of these antigens. As a result, the immune system treats these unfamiliar antigens as foreign and mounts an immune response. Currently, the cross-reactions theory appears to be the favored mechanism of<unk>  pathogenesis.
