14-3-3η Protein: Extracellular 14-3-3η Perpetuates Disease
Extracellular 14-3-3η protein is a potent ligand and activator of intracellular signalling pathways that lead to the up-regulation of inflammation and joint damage factors involved in RA pathogenesis. The 14-3-3η blood test is clinically available as a diagnostic test whereby a positive result indicates a 5 to 50 times greater likelihood of having RA and informs joint damage prognosis and disease monitoring. 14-3-3η is used alone, or in combination with other serological tests and clinical assessment to support RA patient management.
