Mechanisms of Immune Protection by the Adaptive Immune Response

Cellular	Humoral
Lysis of infected cells	Reduction of initial microbial inoculum
Elimination of source of production of viruses and intracellular pathogens	Direct neutralization of pathogen
Elaboration of antimicrobial cytokines	Complement-mediated lysis of bacteria and parasites
Recruitment of innate immune effector cells	Lysis of infected cells through antibody-dependent cell-mediated cytotoxicity
Induction of long-term immune memory	Recruitment of inflammatory cells through complement-dependent mechanisms
Elaboration of chemokines to recruit inflammatory responses	Generation of secretory IgA to facilitate mucosal elimination of pathogens
Secretion of proteins that block pathogen receptors
