چکیده

A series of cyclodextrin-based glycoconjugates, including glycoclusters and star glycopolymers, were synthesized via combination of CuAAC Huisgen coupling and copper-mediated living radical polymerization. These glycoconjugates showed high affinity binding to the human transmembrane lectin DC-SIGN and act as inhibitors to prevent the binding of HIV envelope protein gp120 to DC-SIGN at nanomolar concentrations. The star block glycopolymers showed high loading capacity of hydrophobic anticancer and anti-HIV drugs, indicating promising applications in HIV-therapeutic and smart drug delivery.

PLGA-based macrophage-mediated drug targeting for the treatment of visceral leishmaniasis

The potential of PLGA-nanoparticles as a carrier of amphotericin B and doxorubicin against visceral leishmaniasis was evaluated by macrophage-mediated drug targeting approach. PLGA-nanoparticles were modified by coating them with macrophage-specific ligand-lectin. Prior to in-vitro studies, characterization studies were carried out systematically include particle size, surface morphology, perce...

Cross-priming CD8+ T cells by targeting antigens to human dendritic cells through DCIR.

We evaluated human CD8(+) T-cell responses generated by targeting antigens to dendritic cells (DCs) through various lectin receptors. We found the immunoreceptor tyrosine-based inhibitory motif-containing DC immunoreceptor (DCIR) to mediate potent cross-presentation. A single exposure to a low dose of anti-DCIR-antigen conjugate initiated antigen-specific CD8(+) T-cell immunity by all human DC ...
