Regulation of ICAM-1 in Cells of the Monocyte/Macrophage System in Microgravity

Figure 7

Influence of altered gravity during parabolic flight and sounding rocket flight on ICAM-1 mRNA expression levels. (a) ICAM-1 mRNA expression levels are demonstrated for samples of the 19th DLR parabolic flight campaign after 1 g (light gray), 1.8 g (dark gray), μg (black), and hardware ground controls (H/W, striped) exposure and (b) for samples of the TEXUS-49 campaign after launch and acceleration (BL, dark gray), μg (black), and hardware ground controls (H/W, striped). ICAM-1 fluorescence intensities do not show any significant differences for all compared conditions in both experimental setups. The number of analyzed arrays: 19th DLR PFC: 1 g (), 1.8 g (), μg () and H/W (); TEXUS-49: H/W (), μg (), BL ().
