Process found to play role in rheumatoid arthritis could lead to new treatment

Although the origin of rheumatoid arthritis (RA) remains unclear, bioactive proteins known as cytokines, particularly TNFα and IL-6, which are involved in inflammation, play a major role in the disease by contributing to joint and tissue destruction. Placenta growth factor (PIGF), another cytokine, has been thought to be critical for a new blood vessel formation in the placenta to sufficiently deliver oxygen and nutrients to fetus. A new study examined the effects of PIGF on the inflammatory process of RA. The results suggest that PIGF may play an important role in inflammation in RA joints.
