description

Dendritic cells (DCs) are critical for induction of protective immunity against Leishmania major. However, DC activation occurs only several weeks after parasite transmission. Parasites synthesize a macrophage-inducible C-type lectin (Mincle) ligand. Engagement of Mincle by the parasite ligand dampens DC activation, thus delaying induction of interferon-γ-producing T cells responsible for parasite eradication.
