Conversely, vascular cell adhesion molecule-1 (VCAM-1), monocyte chemoattractant protein-1 (MCP-1), and asymmetric dimethylarginine (ADMA) were found to correlate with the severity of RA-ILD, exhibiting good specificity in assessing pulmonary involvement [14,15,30]. Here, VCAM1 is linked to rheumatoid arthritis.
