Manalpha1-2Man functionalized G(3) and G(4)-PAMAM dendrimers have been synthesized and characterized by MALDI-TOF MS and NMR spectroscopy. Precipitation assays to assess the binding of the dimannose-functionalized dendrimers to Cyanovirin-N, a HIV-inactivating protein that blocks virus-to-cell fusion through high mannose mediated interactions, are presented.

CGL1 is a mannose-specific lectin isolated from the Pacific oyster Crassostrea gigas, and it belongs to the DM9 domain protein family. Each subunit of the CGL1 dimer consists of a tandem repeat of DM9 motifs, which were originally found in the Drosophila melanogaster genome. The CGL1 protomer contains two carbohydrate-binding sites: a high-affinity site A and a low-affinity site B.

The binding property of Con A has been studied intensively and applied widely to glycoconjugates / glycobiology for over 80 years. However, its role and functional relationship of Con A with these mammalian structural units, glycotopes, N-glycan chains, as well as their polyvalent forms in N-glycoproteins involved in the Con A-glycan interactions have not been well defined and organized. In this study, the recognition factors involved in these interactions were analyzed by our well developed method- the enzyme linked lectinosorbent (ELLSA) and inhibition assay.

The human mannose receptor expressed on macrophages and hepatic endothelial cells scavenges released lysosomal enzymes, glycopeptide fragments of collagen, and pathogenic microorganisms and thus reduces damage following tissue injury. The receptor binds mannose, fucose, or N-acetylglucosamine (GlcNAc) residues on these targets. C-type carbohydrate-recognition domain 4 (CRD4) of the receptor contains the site for Ca-dependent interaction with sugars.

New technologies in the field of vaccinology arise as a necessity for the treatment and control of many diseases. Whole virus inactivated vaccines and modified live virus ones used against Bovine Herpesvirus-1 (BoHV-1) infection have several disadvantages. Previous works on DNA vaccines against BoHV-1 have demonstrated the capability to induce humoral and cellular immune responses.

The fimbrial lectin FimH from uro- and enteropathogenic binds with nanomolar affinity to oligomannose glycans exposing Manα1,3Man dimannosides at their non-reducing end, but only with micromolar affinities to Manα1,2Man dimannosides. These two dimannoses play a significantly distinct role in infection by . Manα1,2Man has been described early on as shielding the (Manα1,3Man) glycan that is more relevant to strong bacterial adhesion and invasion.
