MUC5AC and neuroblastoma: Known glycoprotein ligands of Gal-2 include β1 integrin on T cells, mucin 1 (MUC1) in epithelial cancer cells, mucin 5AC (MUC5AC) in gastric mucosa, ganglioside monosialotetrahexosylganglioside 1 (GM1) in neuroblastoma cells, and other molecules such as lymphotoxin-α and β-tubulin, particularly in inflammatory contexts like atherosclerotic plaques [153].
