Give four reasons why secondary immune responses are faster and more effective than primary immune responses
What will be an ideal response?
(i) Memory cells outnumber naive pathogen-specific lymphocytes because they have already gone through clonal selection and proliferation when antigen was encountered previously.
(ii) Memory cells can be activated more quickly than naive lymphocytes.
(iii) Memory cells are not restricted to circulation between the bloodstream and secondary lymphoid organs, but can also enter non-lymphoid tissues and can therefore respond to infections sooner.
(iv) Owing to the molecular processes of somatic hypermutation and isotype switching, immunoglobulins made by memory B cells are of a higher quality and possess constant regions that will direct secreted antibody to the appropriate anatomical locations to combat infection.They will therefore compete more efficiently for antigen than naive lymphocytes and in so doing will inhibit the activation of naive lymphocytes.
