Study Sheds Light on Rheumatoid Arthritis and Its Influence on Atherogenic Lipid Disruptions
Advertisement
A recent study published in the journal Gene Expression indicates that Rheumatoid Arthritis, a systemic autoimmune disorder can contribute to the progression of atherosclerosis.
Rheumatoid arthritis, an inflammatory autoimmune disorder, leads to the production of inflammatory cytokines due to the immune response, which significantly disrupts lipid and lipoprotein metabolism.
There are certain inflammatory mediators responsible for the progression of rheumatoid arthritis like Inflammatory cytokines, such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) which influence lipid and lipoprotein profiles by modulating gene expression and metabolic pathways.
Other inflammatory mediators such as C reactive protein modify the behaviour of low-density lipoprotein(LDL) which ultimately leads to the development of atherosclerotic plaques.
Myeloperoxidase (MPO), an additional inflammatory mediator, generates reactive oxygen species (ROS) that compromise the effectiveness of high-density lipoprotein (HDL). As a result, high-density lipoprotein becomes less efficient at transporting surplus cholesterol away from cells. This impairment in high-density lipoprotein function contributes to the progression of atherosclerosis, a condition characterized by the accumulation of cholesterol and other substances in arterial walls.
