Provoked by sterile/nonsterile insults, prolonged monocyte mobilization and uncontrolled monocyte/macrophage activation can pose imminent or impending harm to the affected organs. Curiously, folate receptor beta (FRβ), with subnanomolar affinity for the vitamin folic acid (FA), is upregulated during immune activation

Although glucocorticosteroids are considered the first-line treatment in sarcoidosis, refractory cases require alternatives, such as methotrexate (MTX). The aim of this study was to develop, on behalf of the World Association of Sarcoidosis and Other Granulomatous Disorders (WASOG), multinational evidence-based
