Notes: The authors previously showed that there are two independent mechanisms by which Chlamydia-specific CD4 T cells clear infection in epithelial cells; an iNOS-dependent mechanism and a Plac8-dependent mechanism. To further identify the Plac8 mechanism, they used microarrays to identify a second mechanism dependent on Plac8 for terminating Chlamydia replication in epithelial cells.
Several Chlamydia-specific CD4 T cell clones were purified at the end of their culture cycle and grown for 3 days in their usual culture media plus growth factors, without Ag stimulation. Total RNA was isolated from each clone using a protocol that included an RNase-free DNase I treatment step. Specific mRNA gene reverse transcription and amplification were performed using the AccessQuick™ RT-PCR System. (4324)
