Studies on the relation between the level of expression of DC-SIGN in human populations and susceptibility to tuberculosis are contradicting each other, varying from a protective effect to increased susceptibility to tuberculosis by high DC-SIGN expression or no correlation at all (Barreiro et al., 2006; Gomez et al., 2006; Ben-Ali et al., 2007; Vannberg et al., 2008;). Here, CD209 is linked to tuberculosis.
