Introduction. the immune response uses multiple strategies to reduce damage to self by turning off responses when pathogen is cleared and avoiding reactions to self antigens. However, these checks and balances can break down, leading to immune-mediated reactions that are more detrimental than protective. . . Localized and Systemic Anaphylaxis.
