Similar results were obtained by Lee et al., who, in their work, showed an increase in activated “naive” B-lymphocytes with CD19+CD38+IgD+ phenotype in the peripheral blood of sarcoidosis patients, whereas the total subpopulation of “naive” B-cells with CD19+CD27−IgD+ phenotype did not significantly differ from that in healthy donors [29]. This evidence concerns the gene CD38 and sarcoidosis.
