Summary
Theileria parasites transform bovine leukocytes, causing diseases like Tropical Theileriosis and East Coast Fever. This review details how these parasites manipulate host cell pathways to induce cancerous phenotypes.
Area of Science:
- Parasitology
- Cell Biology
- Veterinary Medicine
Context:
- Mammalian diseases are often caused by infectious agents like bacteria and viruses.
- Microbes can alter host cell phenotypes by hijacking cellular machinery.
- Theileria parasites are tick-transmitted apicomplexans causing significant livestock diseases.
Purpose:
- To review the mechanisms by which Theileria parasites induce host cell transformation.
- To explore the manipulation of host cellular pathways by Theileria annulata and Theileria parva.
- To understand how parasite infection leads to phenotypes resembling mammalian lymphomas.
Summary:
- Theileria parasites, specifically T. annulata and T. parva, infect bovine leukocytes.
- These parasites are unique eukaryotes capable of inducing host cell transformation, leading to hyperproliferation, invasiveness, and apoptosis evasion.
- Mechanisms involve the manipulation of host cellular signaling pathways, mirroring aspects of human lymphoma.
Impact:
- Provides insights into a unique eukaryotic parasite's ability to induce cancer-like transformations.
- Highlights the role of host-parasite interactions in disease pathogenesis.
- Informs potential therapeutic strategies for Theileria-induced diseases and related cancers.

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...

Parasitism is a form of microbial interaction in which parasitic microbes exploit a host organism for nutrients and shelter, often at the host's expense. Unlike mutualistic relationships, where both organisms benefit, parasitism benefits only the parasite and harms the host.Classification of ParasitesMicrobial parasites are broadly classified based on their location relative to the host.Ectoparasites remain on the host’s surface, such as the skin or outer tissues, drawing nutrients...

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
