Figure 1.
Morphological and functional classification of circulating hemocytes. The upper portion of the figure shows granulocytes, oenocytoids and prohemocytes, while the lower portion lists gene products identified from mosquitoes with roles in three immune defense functions: melanization, phagocytosis, or lysis of pathogens. Solid arrows indicate hemocyte types with major roles in each of these defenses, dotted arrows indicate minor involvement, and dotted lines with circles indicate possible involvement.
