Nonspecific Immunity Immunity is mediated by humoral and cellular effectors.Certain immune responses are antigen specific.They are provoked by unique determinants of the antigens and effectors produce antibodies or T cells which are antigen specific.This requires selection of effectors of appropriate specificity for clonal expansion before an effective response can be observed.In contrast,other imune responses can be evoked by infectious agents or injury in a generalized,antigen nonspecific manner.These responses are not induced by unique determinants.In addition,the effectors produced recognize conserved,rather than unique,determinants.
