Galectin-3 (formerly called Mac-2 antigen) is a ∼30 kDa carbohydrate-binding protein expressed on the surface of inflammatory macrophages and several macrophage cell lines. We have purified from lysates of the murine macrophage cell line WEHI-3 glycoproteins that bind to a galectin-3 affinity column. Several of these receptors are labelled after(More)
Galectin-3, a mammalian galactoside-binding protein, is not expressed in the Jurkat T-lymphoblastoid cell line. However, Jurkat cells express surface glycoprotein receptors for galectin-3, one of which is shown to be the glycosylated heavy chain of CD98 (4F2 antigen), a T-cell activation marker. Addition of galectin-3 to Jurkat cells triggers a sustained(More)
Both IL-23- and IL-1-mediated signaling pathways play important roles in Th17 cell differentiation, cytokine production, and autoimmune diseases. The IL-1R-associated kinase 4 (IRAK4) is critical for IL-1/TLR signaling. We show here that inactivation of IRAK4 kinase in mice (IRAK4 KI) results in significant resistance to experimental autoimmune(More)
