Abstract | Platelet-activating factor (PAF) is a potent inflammatory mediator and it actions are mediated via specific cell surface receptors which are coupled to G-proteins. PAF stimulates several functions in monocytes and may modulate the expression of its own receptor. To investigate the possible modulation of PAF receptor mRNA expression Northern blot analysis of total RNA from human monocytes was performed using the cDNA of human leukocyte PAF receptor as a probe. Following the addition of 100 nM PAF, there was a 2.0-fold increase in PAF receptor mRNA at 60 minutes after the stimulation, which was inhibited by pretreatment with the PAF receptor antagonist WEB 2086. This increase returned to control level at 120 and 180 min. The increase of PAF receptor mRNA was statistically significant for 10 nM to 1 μM of PAF, while 100 nM of lysoPAF did not increase PAF receptor mRNA levels. These results suggest that PAF receptor expression can be regulated by PAF itself at the transcriptional level. |
