Los glicosaminoglicanos de la superficie de la vejiga: un mecanismo eficiente de adaptación al medio ambiente
Science (New York, N.Y.)
|May 9, 1980
Resumen
Los glicosaminoglicanos sintéticos pueden prevenir la adherencia bacteriana en la vejiga, de manera similar a la mucina natural. Esto sugiere el potencial de nuevos tratamientos para reducir las infecciones y la acumulación molecular en el tracto urinario.
Área de la Ciencia:
- Urología Urología Urología.
- La bioquímica es la bioquímica.
- Microbiología Microbiología.
Sus antecedentes:
- El epitelio de transición de la vejiga urinaria produce una capa natural de glicosaminoglicanos.
- Esta capa de mucina natural inhibe la adhesión bacteriana a la superficie de la vejiga.
Objetivo del estudio:
- Investigar la eficacia de los glicosaminoglicanos sulfonados sintéticos en la prevención de la adherencia bacteriana.
- Para determinar si los glicosaminoglicanos sintéticos ofrecen una protección similar a la mucina natural.
- Para explorar los efectos más amplios de antiadherencia en moléculas e iones.
Principales métodos:
- Instilación de glucosaminoglicanos sulfonados sintéticos en las vejigas con las capas de mucina natural eliminadas.
- Comparación de la adherencia bacteriana en las vejigas con y sin glicosaminoglicanos naturales/sintéticos.
- Evaluación de la adherencia al calcio y a las proteínas en presencia de glicosaminoglicanos.
Principales resultados:
- Los glucosaminoglicanos sulfonados sintéticos impidieron efectivamente la adherencia bacteriana, igualando la eficacia de la mucina natural.
- Tanto la mucina natural como el pentosanpolisulfato de sodio sintético redujeron la adherencia al calcio y a las proteínas.
- Las propiedades antiadherentes se extienden a niveles moleculares e iónicos.
Conclusiones:
- Los glicosaminoglicanos sintéticos son una alternativa viable a la mucina natural para prevenir la adherencia bacteriana en la vejiga.
- Estos compuestos son prometedores para reducir las infecciones del tracto urinario y prevenir la acumulación no deseada de moléculas / iones.
- Los hallazgos apoyan el uso de glicosaminoglicanos de superficie para mantener la salud de la vejiga.

01:42The Extracellular Matrix
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.Composition of the Extracellular MatrixThe extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse molecules.
01:47Osmoregulation in Insects
Malpighian tubules are specialized structures found in the digestive systems of many arthropods, including most insects, that handle excretion and osmoregulation. The tubules are typically arranged in pairs and have a convoluted structure that increases their surface area.
01:05Proteoglycans
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...
01:23Glycosaminoglycans
Glycosaminoglycans (GAGs), also known as mucopolysaccharides, are long and linear polymers comprising of specific repeating disaccharides - the amino sugar that can be N-acetylglucosamine or N-acetylgalactosamine, and a uronic acid that is usually glucuronic acid or iduronic acid.
GAGS are found in the extracellular matrix of vertebrates, invertebrates, and bacteria. Due to their polar nature they attract water, and serve as excellent lubricants or shock absorbers in an animal body.

01:14Glycocalyx and its Functions
The glycocalyx is a carbohydrate-rich, fuzzy-appearing layer on the outer surface of the cell membrane. It is highly hydrophilic, because of this it attracts large amounts of water to the cell's surface. This aids the cell's interaction with the watery environment and also helps it to obtain substances dissolved in the water. It is also important for cell identification, self/non-self determination, and embryonic development and is used in cell-to-cell attachments to form tissues.

01:23Urinary Bladder
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
