Trypanosoma cruzi: cell surface dynamics in trypomastigotes of different strains

Capping and shedding of ectodomains in Trypanosoma cruzi may be triggered by different ligands. Here, we analysed the mobility and shedding of cell surface components of living trypomastigotes of the Y strain and the CL Brener clone in the presence of poly-L-lysine, cationized ferritin (CF) and Concanavalin A (Con A). Poly-L-lysine and CF caused intense shedding in Y strain parasites. Shedding was less intense in CL Brener trypomastigotes, and...
