These studies universally demonstrated that mice subjected to LPS/ODE + CIA (vs. LPS/ODE or CIA alone) displayed the highest expression of MAA, citrullinated antigen and vimentin in resected lung tissues, with strong co-localization of MAA with citrulline, similar in magnitude to that reported in human RA-ILD tissues (23) (Table 2). Here, VIM is linked to interstitial lung disease.
