to evaluate the concept that recruitment of blood monocytes to the sarcoid lung is mediated by chemoattractants produced by immune effector cells within the lung , we obtained mononuclear cells from lung and blood of six patients with active pulmonary sarcoidosis , six normal subjects , and six patients with active idiopathic pulmonary fibrosis and studied their ability to secrete a chemotactic factor for monocytes .
