Abstract
Galectin-3 is a β-galactoside–binding lectin widely expressed on epithelial and hematopoietic cells, and its expression
is frequently associated with a poor prognosis in cancer. Because it has not been well-studied in human
infectious disease, we examined galectin-3 expression in mycobacterial infection by studying leprosy, an intracellular
infection caused by Mycobacterium leprae. Galectin-3 was highly expressed on macrophages in lesions of
patients with the clinically progressive lepromatous form of leprosy; in contrast, galectin-3 was almost undetectable
in self-limited tuberculoid lesions. We investigated the potential function of galectin-3 in cell-mediated
immunity using peripheral blood monocytes. Galectin-3 enhanced monocyte interleukin 10 production to a
TLR2/1 ligand, whereas interleukin 12p40 secretion was unaffected. Furthermore, galectin-3 diminished monocyte
to dendritic cell differentiation and T-cell antigen presentation. These data demonstrate an association of galectin-
3 with unfavorable host response in leprosy and a potential mechanism for impaired host defense in humans.
