Functions Of Humoral Immunity
|
-Eliminates extracellular pathogens
-Works with phagocytes & complement -Neutralizes Viruses, toxins -Can be passively transferred |
|
|
What cells are involved in humoral immunity
|
Antigen Presenting Cells
-Dendritic Cells -Macrophages -B cells |
|
|
First Step Of B cell Activation
|
Pathogen engulfed by Antigen Presenting Cells
|
|
|
Second Step Of B cell Activation
|
-APC's degrade pathogens into pieces
-Antigens are placed onto receptors on APC surface |
|
|
Third Step of B cell Activation
|
-APC loaded with antigen moleculescomes into contact w/T helper cells
-Th cell becomes activated |
|
|
Fourth Step of B cell Activation
|
-Activated Th cells grow and divide
-Activate B cells by similar receptor recognition and binding(clonal selection) -Activated B cells grow and divide -some become memory cells and some plasma cells |
|
|

|
|
How are Antibodies Useful?
