This internalization, processing and subsequent MHC presentation may result in a strong T cell stimulation. Here, we hypothesized that combining mannose glycodendrons with multivalent presentation of peptide epitopes in a likewise dendron format would yield hybrid constructs, named glycodendropeptides (GDPs), with the capacity to enhance peptide immunogenicity, hence providing a novel and versatile platform for applications in immunotherapy. Thus, GDPs of different valencies displaying the NP366-374 epitope, a conserved sequence from the influenza A virus nucleoprotein (NP), have been built by two click chemistry-based methodologies and assessed as potential flu vaccine candidates. Preliminary evaluation of the ability of these constructs to stimulate dendritic cell maturation and lymphocyte proliferation was promising, showing the highest-functionalized NP366-374 GDPs as inducing the strongest immunostimulatory effect. eng Moléculas de adhesión celular Química clic Secuencia conservada Dendrómeros Células dendróticas Epítopos Inmunoterapia Lectinas tipo C Manosa Lectinas de unión a manosa Péptidos Proteínas de unión al ARN Receptores de superficie celular Linfocitos T Vacunas Proteínas del centro vírico Glycodendropeptides stimulate dendritic cell maturation and T cell proliferation: a potential influenza A virus immunotherapy research article
