Asialo Gm1

AbstractSeviL is a recently isolated lectin found to bind to the linear saccharides of the ganglioside GM1b (Neu5Ac$$\alpha$$ α (2-3)Gal$$\beta$$ β (1-3)GalNAc$$\beta$$ β (1-4)Gal$$\beta$$ β (1-4)Glc) and its precursor, asialo-GM1 (Gal$$\beta$$ β (1-3)GalNAc$$\beta$$ β (1-4)Gal$$\beta$$ β (1-4)Glc). The crystal structures of recombinant SeviL have been determined in the presence and absence of ligand. The protein belongs to the $$\beta$$ β -trefoil family, but shows only weak sequence similarity to known structures. SeviL forms a dimer in solution, with one binding site per subunit, close to the subunit interface. Molecular details of glycan recognition by SeviL in solution were analysed by ligand- and protein-based NMR techniques as well as ligand binding assays. SeviL shows no interaction with GM1 due to steric hindrance with the sialic acid branch that is absent from GM1b. This unusual specificity makes SeviL of great interest for the detection and control of certain cancer cells, and cells of the immune system, that display asialo-GM1.

Cord Lesion

Anti-ganglioside serum titers were evaluated by ELISA in 150 patients with complete spinal cord lesion for 6 to 12 months (IgG monosialo GM1, IgM monosialo GM1, IgG asialo GM1, IgM asialo GM1, IgG disialo GD1b e IgM disialo GD1b) prior to treatment with GM1 100 mg/day i.m. Only 4 patients showed positive titers for anti-asialo-GM1 (IgM) antibodies . All patients were clinically examined during and after treatment. No important side effects were observed with GM1 therapy. These results suggest that GM1-ganglioside administration in patients with chronic spinal cord injury is safe.
