Abstract:

a number of glycoconjugates, including glycolipids and glycoproteins, participate in the process of host-cell invasion by trypanosoma cruzi and one of the most important carbohydrates involved on this interaction is sialic acid. it is known that parasite trans-sialidase participates with sialic acid in a coordinated fashion in the initial stages of invasion. given the importance of these sialogycoconjugates, this review sets out various possible biological models for the interaction between the parasite and mammalian cells that possess a sialylated receptor/ligand system.
