Abstract:
Shigella is a well-known etiological agent responsible for intestinal infection among children, the elderly, and immunocompromised people ranging from mild to severe cases. Shigellosis remains endemic in Malaysia and yet there is no commercial vaccine available to eradicate the disease. Iron is an essential element for the survival of Shigella within the host. Hence, it is required for regulating metabolic mechanisms and virulence determinants. Alteration of iron status in the extracellular environment directly triggers the signal in enteropathogenic bacterial, providing information that they are in a hostile environment. To survive in an iron-limited environment, molecular regulation of iron-binding proteins plays a vital role in facilitating the transportation and utilization of sufficient iron sources. Given the importance of iron molecules for bacterial survival and pathogenicity, this review summarizes the physiological role of iron-binding proteins in bacterial survival and their potential use in vaccine and therapeutic developments.
Insights
Shigella causes intestinal infections, and iron is crucial for its survival and virulence. Iron-binding proteins are key to Shigella
Area of Science:
- Microbiology
- Immunology
- Infectious Diseases
Background:
- Shigella is a significant cause of intestinal infections, particularly in vulnerable populations.
- Shigellosis is endemic in Malaysia, with no current vaccine available.
- Iron is essential for Shigella's survival, metabolism, and virulence within the host.
Purpose of the Study:
- To review the physiological roles of iron-binding proteins in bacterial survival.
- To explore the potential of iron-binding proteins in developing vaccines and therapeutics against Shigella.
Main Methods:
- Literature review focusing on iron metabolism and virulence factors in Shigella.
- Analysis of molecular regulation mechanisms for iron uptake and utilization.
- Examination of existing research on iron-binding proteins in bacterial pathogenesis.
Main Results:
- Iron availability significantly influences Shigella's adaptation and pathogenicity.
- Iron-binding proteins are critical for acquiring and utilizing iron in limited environments.
- Regulation of iron metabolism is a key factor in Shigella's virulence.
Conclusions:
- Iron-binding proteins are vital for Shigella survival and pathogenicity.
- Targeting iron-binding proteins presents a promising strategy for novel vaccine and therapeutic development against shigellosis.
