Apicomplexa parasites, including malaria-causing Plasmodium, possess unique cytoskeletal structures. This review details their actin, myosin, microtubules, and novel intermediate filaments, crucial for parasite functions.
Area of Science:
- Parasitology
- Cell Biology
- Molecular Biology
Background:
- Apicomplexa are obligate intracellular parasites responsible for significant human and agricultural diseases.
- Key examples include Plasmodium (malaria), Toxoplasma (toxoplasmosis), Cryptosporidium, Eimeria, and Theileria.
- These parasites exhibit conserved yet unique cellular structures and processes.
Purpose of the Study:
- To review the current understanding of the Apicomplexa cytoskeleton.
- To explore the properties of cytoskeletal proteins and their roles in parasite biology.
- To highlight novel cytoskeletal elements discovered in these parasites.
Main Methods:
- Literature review of existing research on Apicomplexa cytoskeleton.
- Analysis of published data on cytoskeletal protein properties and functions.
- Synthesis of information regarding motility, invasion, and replication mechanisms.
Main Results:
- Apicomplexa possess unusual actin and myosin proteins.
- Microtubule organization is highly stereotyped across different apicomplexan species.
- Novel intermediate filament-like structures have been identified.
Conclusions:
- The Apicomplexa cytoskeleton is a complex and dynamic structure essential for parasite survival.
- Understanding these elements offers potential targets for antiparasitic interventions.
- Further research into novel cytoskeletal components may reveal new therapeutic strategies.

Introduction to the Cytoskeleton
The cytoskeleton is a network of protein filaments present within the cell, having three distinct filaments ̶ microfilaments, microtubules, and intermediate filaments. Each has characteristic features that distinguish them, including the dynamics of their assembly and disassembly, mechanical properties, polarity, and the type of molecular motors associated with them. Earlier, they were thought to be present only in eukaryotic cells; however, their homologs were...
