Antibodies against different cytoskeletal proteins were used to study the cytoskeletal organization of human spermatozoa. A positive staining with actin antibodies was seen in both the acrosomal cap region and the principal piece region of the tail. However, no staining was obtained with nitrobenzoxadiazol-phallacidin, suggesting that most of the actin was in the nonpolymerized form. Most of th...
Carbohydrates participate in almost every aspect of biology from protein sorting to modulating cell differentiation and cell-cell interactions. To date, the majority of data gathered on glycan expression has been obtained via analysis with either anti-glycan antibodies or lectins. A detailed understanding of the specificities of these reagents is critical to the analysis of carbohydrates in bio...
Objetive. This study was conducted to evaluate, by means of lectinhistochemistry (LHC), the expression of carbohydrates in granulomas induced by the bacillus Calmette-Guerin (BCG) in muscle tissue of Piaractus mesopotamicus after 33 days. Material and methods. Histological sections with 3 μm thick were incubated with the following lectins :WGA (Wheat germ agglutinin), DBA (Dolichos biflorus agg...
-l, A lectin fraction has been isolated from mucus produced by the snail Helix aspersa by affinity chromatography of mucus protein on Sephadex G-100. The lectin is eluted with D-glucose. It agglutinates rabbit red blood cells but not human type A and is inhibited by o-GalNAc and to a lesser extent o-GlcNAc and D-Gal. 2. The anti-A agglutinin of the Helix albumin gland was isolated by the same m...
BACKGROUND The pathological classification of cryptogenic fibrosing alveolitis has been a matter of debate and controversy for histopathologists. OBJECTIVE To identify and specify the glycotypes of capillary endothelial cells in usual interstitial pneumonia (UIP) compared to those found in normal tissue. METHODS Sections of formalin-fixed, paraffin-embedded blocks from 16 cases of UIP were ...
Bioactive products from snail slime of “Helix” specie have potential applications in preventing and/or treating several human diseases and in cancer diagnosis. However, the poor pharmacokinetics characteristics of these natural compounds limit their use. Nanotechnology offers promising solutions for the enhanced formulation of these molecules through the synthesis of nanosized drug del...
Unlike vertebrates, insects do not have an Ab-based nonself recognition system, and must rely totally on innate immunity to defend themselves from microbial invaders. The most likely candidates for recognizing foreign material in insects are the lectins, which have already been shown to be important in mammalian innate immunity. The hemolymph of the cockroach, Blaberus discoidalis, contains mul...
