Lectins are proteins extensively used in biomedical applications with property to recognize carbohydrates through carbohydrate-binding sites, which identify glycans attached to cell surfaces, glycoconjugates, or free sugars, detecting abnormal cells and biomarkers related to diseases. These lectin abilities promoted interesting results in experimental treatments of immunological diseases, wound...

Plant and invertebrate lectins are valuable cyto- and histological tools for the localization of defined carbohydrate determinants. The well-documented ubiquitous occurrence of sugar receptors encourages functional considerations. Undoubtedly, analysis of the presence of vertebrate lectins in tissues and cells is required to answer the pertinent and tempting question on the physiological releva...

A panel of ten lectins with different carbohydrate specificities, including three original lectin preparations (MPFA, LABA, and LVA), was used for the investigation of rat kidney glycoconjugate remodeling during postnatal morphogenesis, and the findings were compared with the impairments seen in streptozotocin-induced diabetic nephropathy. Postnatal morphogenesis was accompanied by the accumula...

SAITO, K. and NAKANUMA, Y. Lectin Binding of Intrahepatic Bile Ducts and Peribiliary Glands in Normal Livers and Hepatolithiasis. Tohoku J. Exp. Med., 1990, 160 (1), 81-92 Histochemical features of the intrahepatic bile ducts and peribiliary glands were examined with five biotinylated lectins in 12 normal human livers and 12 livers with hepatolithiasis. There was a marked proliferation of perib...

Hypoxic areas in solid tumors are often associated with poor prognosis and resistance to chemotherapy. The aim of the study was to analyze the expression of galectin-1 (Gal-1), galectin-3 (Gal-3), sialic acid and b1-6 branched glycan structures in hypoxic environment of invasive ductal carcinoma (IDC) of the breast. We performed lectin histochemistry with phytohemag glutinin-L (L-PHA) and Sambu...

The view on the significance of the presence of glycans in glycoconjugates is undergoing a paradigmatic change. Initially mostly considered to be rather inert and passive, the concept of the sugar code identifies glycans as highly versatile platform to store information. Their chemical properties endow carbohydrates to form oligomers with unsurpassed structural variability. Owing to their capac...
