Describe three types of unwanted and potentially harmful immune response
What will be an ideal response?
(i) Allergy. IgE antibodies made against normally innocuous environmental antigens trigger widespread mast-cell activation. This can lead to allergic diseases such as asthma or to a potentially fatal anaphylactic reaction.
(ii) Autoimmune disease. Chronic immune responses by B cells or T cells to self antigens can cause tissue damage and chronic illnesses such as diabetes, multiple sclerosis, and myasthenia gravis. Autoimmunity is sometimes provoked as a consequence of an immune response to pathogen-derived antigen that cross-reacts on healthy host cells or tissue.
(iii) Transplant rejection. A person's immune system will make an immune response against the foreign MHC molecules on transplanted tissue that is MHC-incompatible.
