PEPTIDE-MEDIATED REGULATION OF THE ALLERGIC IMMUNE-RESPONSE

A major key to successful immunotherapy may depend on altering the qua litative nature of the immune response in allergic patients. In this r eveiew we examine how immune responses to environmental allergens are regulated? and the mechanisms used by the immune system to prevent all ergic sensitization. We also discuss future prospects of using allerge n-derived peptides in immunotherapy and the possibility of 'reprogramm ing' the immune responses by immunizing under conditions that promote Th I responses instead of Th2 responses.
