Example text

Perhaps of more relevance to AMD is the contribution of reparative macrophages to glomerulosclerosis. Recruitment of blood-derived reparative macrophages develops early in the course of glomerulosclerosis in proportion to the severity of the injury (151,152). Various innate injury stimuli, including renal hypertension, hyperlipidemia, and glomerular capillary endothelial injury by oxidized LDL, can upregulate macrophage chemotactic factors and adhesion molecules in the capillaries to induce macrophage recruitment (156–158).

Further, macrophage involvement may be underestimated in AMD. Choroidal macrophages are often difficult to detect by routine histopathology in noninflammatory disorders because they typically acquire much flattened profiles. Finally, evidence from several recent clinical trials has shown a benefit from intravitreal corticosteroid therapy in the treatment of CNV in AMD patients (180,181). Corticosteroids are potent modulators of macrophage function and these studies suggest that more research should explore the therapeutic potential of nonspecific anti-inflammatory therapy in AMD.

Intravascular circulating antibodies can bind antigen in the blood, thereby form circulating immune complexes (ICs). Then the entire complex of antigen plus antibody can deposit into tissues. Alternatively, circulating B cells can infiltrate into a tissue and secrete antibody locally to form an IC. Third, antibody can bind to an effector cell (especially mast cell, macrophage, or neutrophil) by the Fc portion of the molecule to produce a combined antibody and cellular effector mechanism. It is unlikely that any of these mechanisms play a major role in AMD.
