NSF Budget Request to Congress FY 2005 cover

Macrophages circulate through the blood, searching for bacterial infection. When bacteria are found, macrophages engulf and digest them. This series of three paintings shows a macrophage engulfing a bacterium. Only a portion of the two cells, where a pseudopod of the macrophage is extending over the bacterium, is shown. The original paintings are 1 meter tall--at this magnification, the macrophage would fill most of a building.
