Summary
Glycans significantly influence how natural killer cells and antibodies combat pathogens and harmful cells. Understanding these interactions is key to developing new therapeutic strategies.
Area of Science:
- Immunology
- Glycobiology
- Cellular Biology
Background:
- Glycans are crucial carbohydrate structures on cell surfaces.
- Natural killer (NK) cells are vital immune cells involved in innate immunity.
- Antibodies facilitate immune responses against pathogens and abnormal cells.
Purpose of the Study:
- To investigate the role of glycans in NK cell-mediated immunity.
- To elucidate how glycan structures modulate NK cell-antibody interactions.
- To explore the therapeutic potential of targeting glycan-mediated pathways.
Main Methods:
- Analysis of glycan profiles on target cells and immune components.
- Functional assays assessing NK cell cytotoxicity and antibody-dependent cellular cytotoxicity (ADCC).
- In vitro and in vivo models of infection and cancer.
Main Results:
- Specific glycan structures were found to enhance or inhibit NK cell activation.
- Antibody binding to target cells is significantly influenced by cell surface glycans.
- Modulation of glycans altered the efficacy of NK cell and antibody-mediated killing.
Conclusions:
- Glycans are critical regulators of NK cell and antibody function.
- Targeting glycan-immune cell interactions offers a promising avenue for immunotherapy.
- Further research into glycan-specific therapies is warranted.

01:14Glycocalyx and its Functions
3.7K
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.

01:25Protein Glycosylation
6.8K
Glycosylation, the most common post-translational modification for proteins, serves diverse functions. Adding sugars to proteins makes the proteins more resistant to proteolytic digestion. Glycosylated proteins can act as markers and receptors to promote cell-cell adhesion. Additionally, they have many essential quality control functions in the cell, such as correct protein folding and facilitating transport of misfolded proteins to the cytosol, which can be degraded.

01:05Proteoglycans
3.9K
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
4.8K
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.

01:21Matrix Proteoglycans and Glycoproteins
3.8K
Proteoglycans are extensively glycosylated proteins, commonly found in the extracellular matrix, interwoven with collagen fibers. Hyaline cartilage, the most common type of cartilage in the body, consists of short and dispersed collagen fibers associated with large amounts of proteoglycans. These proteoglycans have long negative charges that attract cations, which in turn attract water molecules. This influx of ions and water molecules swells up the proteoglycan like a water-soaked gel that can...

01:24Oligosaccharide Assembly
2.8K
Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.
