Occurrence of an intracellular inhibitor of ectosialyltransferase in lymphocytes

“…It has been demonstrated that the presence of sialic acid at the non-reducing end of glycoconjugates has a biological significance either at a molecular leve1 or at a cellular level: sialyl residues appear to be signal for the life time of serum glycoproteins [l] or cells [2,3] and have related to cellular adhesion [4] and crypticity of immunogenic loci [S].…”
