Pathogenesis of inflammatory diseases

The JAK-STAT pathway plays a central role in chronic inflammatory diseases, such as rheumatoid arthritis (RA).1,2

In RA, inflammation is the major contributor to disability in early disease; radiographic progression dominates disability later in the disease process.3

Disease progression in RA4

Dysregulation of immune response ignites the uncontrolled inflammation of RA, which is fuelled by excessive signalling via the JAK-STAT pathway.1,5


Excessive signalling via the JAK-STAT pathway fuels inflammation.6
