types of adaptive immunity

What are the types of Adaptive Immunity?

CELL MEDIATED IMMUNITY

HUMORAL IMMUNITY

■ T cell immunity

CELL MEDIATED IMMUNITY

■ B cell immunity

■ ** works together, failure can alter its effectiveness

HUMORAL IMMUNITY

• T cell

• Arm of the adaptive immune response

• Protects the host against infection by intracellular pathogens

• Main function: destruction of microbes that survived in the cytoplasm or phagocytic vesicle of an infected cell

• Can sometimes be harmful to host

  • Transplanted tissue and certain autoimmune diseases

CELL MEDIATED IMMUNITY

● B cell

● Mediated by antibody present in different body fluids or secretions (saliva, blood, vaginal secretions)

● Antibodies produced by B cells are very effective free floating and can be easily accessed and neutralized

● Migrate to the secondary lymphoid organ such as spleen and lymph nodes

Phases of an Immune Response

RECOGNITION PHASE

AMPLIFICATON PHASE

EFFECTOR PHASE

TERMINATION PHASE

MEMORY

● Innate immune receptor binds to common molecular motifs on pathogens or Ab bound to invader

● Involves highly specific Ag

RECOGNITION PHASE

● Innate immune receptor binds to common molecular motifs on pathogens or Ab bound to invader

RECOGNITION PHASE

● Involves highly specific Ag

RECOGNITION PHASE

● involves complement cascade

● production of soluble factors (cytokines, acute phase reaction, etc) ● recruitment of army cells (WBC)- INNATE

● proliferation of B and T lymphocytes - ADAPTIVE

AMPLIFICATON PHASE

● involves complement cascade

AMPLIFICATON PHASE

● production of soluble factors (cytokines, acute phase reaction, etc) ● recruitment of army cells (WBC)- INNATE

AMPLIFICATON PHASE

● proliferation of B and T lymphocytes - ADAPTIVE

AMPLIFICATON PHASE

● results in the removal of antigens in different mechanism

● phagocytosis, neutralization, opsonization

EFFECTOR PHASE

● dampens the immune system after the antigen has been cleared

● critical phase

● for prevention of excessive responses that may harm the host (tissue damage)

TERMINATION PHASE

● dampens the immune system after the antigen has been cleared

TERMINATION PHASE

● critical phase

TERMINATION PHASE

● for prevention of excessive responses that may harm the host (tissue damage)

TERMINATION PHASE

● involves the generation of long lived B and T lymphocytes

● these cells have low threshold for activation and will react quickly
