Insights

Microbial lectins from pathogens like Entamoeba histolytica and free-living amoebae are key to host damage. Targeting these lectins offers potential for new diagnostic and therapeutic strategies against amoebic infections.

Area of Science:

  • Microbiology
  • Parasitology
  • Immunology

Background:

  • Microbial lectins are increasingly studied for their role in pathogen virulence.
  • Specific lectins from Entamoeba histolytica, Acanthamoeba castellanii, Balamuthia mandrillaris, and Naegleria fowleri contribute to host cell damage and immune evasion.

Purpose of the Study:

  • To review the significance of microbial lectins in protozoan pathogenesis.
  • To highlight lectins as potential targets for therapeutic and diagnostic interventions.

Main Methods:

  • Literature review of studies on microbial lectins and their functions.
  • Analysis of the roles of specific lectins in adhesion, cytotoxicity, and immune response modulation.

Main Results:

  • The Gal/GalNAc lectin of E. histolytica is involved in adhesion, cytotoxicity, and immune regulation.
  • Mannose- and galactose-binding proteins in Acanthamoeba castellanii and Balamuthia mandrillaris, respectively, contribute to host damage.
  • Mannose and fucose-containing molecules in Naegleria fowleri are implicated in adhesion and cytotoxicity.

Conclusions:

  • Microbial lectins are crucial virulence factors in pathogenic protozoa.
  • These lectins represent promising targets for developing novel diagnostic tools, vaccines, and treatments against amoebic infections.

Diversity of Protists I

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Selectins

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,...

Adherens Junctions01:24

Adherens Junctions

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.

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
