Summary

Schistosome parasites, the cause of schistosomiasis, utilize parasite carbohydrates to evade immune responses and cause disease. Understanding parasite glycobiology may lead to new vaccines and therapies.

Antibodies to glycans dominate the host response to schistosome larvae and eggs: is their role protective or subversive?

The Journal of infectious diseases·2001

Area of Science:

  • Parasitology
  • Immunology
  • Glycobiology

Background:

  • Schistosomes, or blood flukes, cause schistosomiasis, a disease with significant pathology driven by parasite eggs.
  • Parasite-synthesized carbohydrates on glycoproteins, glycolipids, and glycosaminoglycans are implicated in immune evasion and disease.
  • These glycoconjugates and associated proteins play roles in egg adhesion and granuloma formation.

Purpose of the Study:

  • To review current knowledge on schistosome glycoconjugates.
  • To highlight their immunological and biological properties.
  • To explore the potential of glycobiology in developing schistosomiasis interventions.

Main Methods:

  • Literature review of existing research on schistosome glycoconjugates.
  • Analysis of studies on immune responses to parasite carbohydrates.
  • Examination of evidence linking glycoconjugates to disease pathogenesis.

Main Results:

  • Parasite carbohydrates are targets of humoral immunity and modulate host responses.
  • Carbohydrate antigens show potential for inducing protective immunity.
  • Glycoconjugates and lectins are involved in key pathological processes like egg adhesion and granuloma formation.

Conclusions:

  • Schistosome glycoconjugates are critical in host-parasite interactions and disease.
  • Further understanding of parasite glycobiology offers promising avenues for carbohydrate-based vaccines and diagnostics.
  • Exploiting glycobiology may lead to novel therapeutic strategies for schistosomiasis.
