EXPLANATION
Proteins that ↑due to infection, injury, trauma (e.g., C-reactive protein, alpha-1 antitrypsin, haptoglobin,
fibrinogen, ceruloplasmin, alpha-1 acid glycoprotein, complement).
Antibody formed in response to antigens from individuals of same species.
Foreign substance that stimulates antibody production. Large, complex molecules (MW >10,000), usu-
ally protein or polysaccharide.
Immunoglobulin produced by plasma cells in response to ag.
Ab against self.
Strength of bond between ag & ab.
Cytokines that attract cells to a particular site. Important in inflammatory response.
Migration of cells toward chemokine.
Antigenic features of leukocytes.
Chemicals produced by activated immune cells that affect function of other cells. Includes interferons,
chemokines, tumor necrosis factors, transforming growth factors, colony stimulating factors, interleukins.
Determinant site on ag.
