Current Opinion in Immunology
... The use of SIT for AID has lagged behind SIT for allergy. This may be because AIDs are more heterogeneous than allergic diseases; the disease-initiating or target antigen may not be known; and/or the immune pathogenesis of AID is associated with epitope spreading [18] and substantial tissue damage m ...
