VIM and Granuloma: We utilized an in vitro model of human granuloma formation using sarcoidosis patient human peripheral blood mononuclear cells (PBMCs) and an in vivo vimentin-induced pulmonary sarcoidosis model in unique humanized βc transgenic (hβcTg) mice to assess the efficacy of βc antagonism in reducing granuloma formation and evaluate the underlying mechanism of action.
