MAB particles <2μm with an equivalent multiplicity of infection (MOI) of 10:1 (and a total endotoxin level of ≤ 1.115 EU/ml) were incubated with PMBCs extracted from treatment-naive individuals with sarcoidosis who had negative tuberculosis IFN-γ release assays (IGRA). This evidence concerns the gene IFNG and sarcoidosis.
