3 lines of defence |
External barriers Non-specific defemse mech(proteins, cells, processes) Adaptive immune system('memory' of the pathogen) |
|
|
Recognition mech of innate(non specific) immunity |
Rapid response Fixed Limited number of specifications Constant during response |
|
|
Recognition mechanisms and adaptive immunity |
Slow response Variable Numerous highly selective specifications Improve during response |
|
|
Inate immunity two parts |
1. Pathogen recognition: -Soluable proteins and cell surface receptors -Bind to pathogen and its products or to human cells and serum proteins that become altered in precense of pathogen 2. Recruitment of descructive effector mechanisms -effector cells engulf bacteria, kill virus-infected cells, or attack protozoan parasites |
|
|
Interferons |
-Secreted by cells infected w viruses -Alert neighbouring cells to protect them from being infected -Activate NK cells and macrophages=destruction of infected cells |
