Summary
Pathogens exploit host or self-produced galectins, which are glycan-binding proteins, to establish infections. This review details how microbes leverage galectins to evade immune responses and promote disease.
Area of Science:
- Immunology
- Microbiology
- Glycobiology
Background:
- Galectins are versatile glycan-binding proteins with crucial roles in immune regulation and cellular functions.
- Both host and pathogen galectins can influence the course of infections.
- Galectins interact with glycans on host cells and pathogens, modulating host-pathogen interactions.
Purpose of the Study:
- To review how various pathogens utilize galectins to establish and maintain infections.
- To highlight the dual role of galectins in either combating or facilitating pathogen invasion.
- To summarize the mechanisms by which pathogens exploit galectin-binding properties.
Main Methods:
- Literature review of studies on galectins and infectious diseases.
- Analysis of host-pathogen interactions involving galectins.
- Categorization of pathogens based on their galectin utilization strategies.
Main Results:
- Pathogens employ diverse strategies to exploit host galectins for immune evasion and colonization.
- Some pathogens produce their own galectins to manipulate host immune responses.
- Galectin interactions can either hinder or promote pathogen survival and spread.
Conclusions:
- Galectins represent a significant target for pathogens seeking to overcome host defenses.
- Understanding pathogen-galectin interactions is crucial for developing novel anti-infective strategies.
- Targeting galectin pathways offers potential therapeutic avenues against various infections.

Adherens Junctions
5.8K
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

Receptor-mediated Endocytosis
7.2K
Receptor-mediated endocytosis is when bulk amounts of specific molecules are imported into a cell after binding to cell surface receptors. The molecules bound to these receptors are taken into the cell through inward folding of the cell surface membrane, which is eventually pinched off into a vesicle within the cell. Structural proteins, such as clathrin, coat the budding vesicle.

Defense Against Bacterial Pathogens
2.4K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Glycocalyx and its Functions
7.2K
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.

Selectins
3.8K
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...
