The events following the administration of GN8 in vitro, in vivo and ex vivo, lead to increased expression of CD69. The CD69-dependent IFNg production is modulated by co-activation of NKG2D and Ly49 receptors. Glycodendrimers can assist the dissection of activation network of NK/NKT cell lectin-like receptors in rat and murine models

Masking oligosaccharide sequences can assist transformed cells to escape immune surveillance. N-acetyl-glucosamine coated dendrimers have binding affinity for NKR-P1 receptor and can also modify cancer cell glycosylation profile. Effects of treatment on immune cell subpopulations were analyzed in blood, lymphoid tissues and organs, and inside tumor in B16F10 melanoma bearing mice. Treatment enhanced tumor cell immunogenicity, and induced maturation,differentiation and homing of cytotoxic cells to tumor microenvironment.
