Previous data obtained from experiments either in space or in clinostats have shown that: a) human T lymphocytes activation is strongly inhibited; b) the distribution of protein kinase C (PKC) in human leukocytes is altered; c) expression of IL-2 and IL-2-R-alpha is altered. In this study we focus our attention on different isoforms of PKC to determine whether microgravity directly affects the activity and subcellular distribution of PKC. This work was carried out with Con A and anti-CD 28 activated human T cells in simulated microgravity conditions in the Random Positioning Machine (RPM). The cellular fractions (nuclear, cytosolic and membrane) extracted were subjected to Western blotting and RT-PCR analysis. |
