Profiling of CD14+ monocytes from paired rheumatoid arthritis (RA)-patient peripheral blood and synovial fluid samples

ABSTRACT: CD14+ monocytes sorted from the synovial fluid or peripheral blood of rheumatoid arthritis patients were analyzed by full transcriptome microarray analysis. Monocytes from healthy control samples (peripheral blood) were also profiled. Overall design: A total of 26 samples consisting of 16 paired and 2 un-paired synovial fluid and peripheral blood derived CD14+ monocytes from RA-patients, as well as peripheral blood CD14+ monocytes from 8 healthy control subjects were compared. Sorted monocytes (at least of 95% purity) from each of the donors were obtained individually, and compared by full transcriptome profiling.

Monocytes and macrophages are key mediators of inflammation in rheumatoid arthritis (RA). Their persistence at the inflammatory site is likely to contribute to immunopathology. We sought to characterise one mechanism by which persistence may be achieved: resistance to apoptosis and the role of mir-155 in this process. CD14+ monocytes from peripheral blood (PBM) and synovial fluid (SFM) of RA patients were found to be resistant to spontaneous apoptosis relative to PBM from healthy control (HC) in  ...[more]
