By contrast, CD11b+ cells from patients with other lung diseases or from control individuals barely expressed DC-SIGN (2.9 ± 1.8% in patients with asthma, Mann-Whitney test p < 10−7; 3.7 ± 4.1% in patients with sarcoidosis, Mann-Whitney test p < 10−6; 1.9 ± 2.0% in other individuals, Mann-Whitney test p < 10−5; all as compared to the group of patients with TB). This evidence concerns the gene ITGAM and tuberculosis.
