ABSTRACT Rheumatoid arthritis (RA) is a chronic inflammatory disorder affecting synovial joints. Neutrophils are believed to play an important role in both the initiation and progression of RA, and large numbers of activated neutrophils are found ... both synovial fluid (SF) and synovial tissue from RA joints. In this study we analysed paired blood and SF neutrophils from patients with severe, active RA (DAS28> 5.1, n=3) using RNA-seq. ... by incubating healthy control neutrophils in cell-free RA SF, which was able to delay apoptosis and ...

When Ra-1 cells were mated with females, a small fraction of the donors transferred markers via the Ra-2 mode. This effect was enhanced by preconjugal ultraviolet (UV) treatment of the Ra-1 cells. Among the survivors of UV-treated Ra-1 cells, a few stable Ra-2 cells were found. When Ra-2 cells were used as the donors, some ...
