Notes on Primary Response to Antigen

  >   Rahul's Noteblog   >   Notes on Immunology   >   Notes on Primary Response to Antigen

Heptans:

• Too small to induce immune response.

Extravasation of Phagocytes:

• Rolling, activation by chemoattractants (eg., IL-8, LTB4), arrest and adhesion, and transendothelial migration.

Leukocyte adhesion deficiency:

• Absence of CD18; leukocytes don't undergo adhesion; omphalitis, swelling and inflammation of umbilical cord.

Opsonization:

• If antigen is coated with IgG or C3B, phagocytosis is 4000 times stronger.

Inside Macrophage:

• Respiratory burst.

NADPH Oxidase:

• Neutralizes superoxide; creates hydroxyl radical and hydrogen peroxide; oxygen-independent.

Myeloperoxidase:

• Uses NADPH oxidase-produced hydrogen peroxide and chloride ion to create microbicidal hypochlorite; oxygen-dependent.

Chronic Granulomatous Disease (CGD):

• Deficient NADPH oxidase; person will be infected with catalase+ (but not catalase-) organisms.

• Oxygen-independent mechanism kills: catalase-positive organisms; oxygen-dependent mechanism kills: catalase-negative organisms.
