American Trypanosomiasis

American Trypanosomiasis

Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...

Diversity of Protists I

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...

Reporter Genes

Reporter Genes

Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
Commonly used reporter...

Antiprotozoal Agents

Antiprotozoal Agents

Leishmaniasis is a widespread parasitic disease caused by several Leishmania species. It affects millions of people each year and remains a major public health problem in endemic regions. First-line treatment relies on pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate. Even so, how these drugs work has not been fully clear, especially their interaction with parasite-specific biochemical pathways. One key target is trypanothione reductase (TR), an enzyme that...

What is Gene Expression?

What is Gene Expression?

A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then processed and...

Background:

Trypanosomatid protozoa (Leishmania spp., Trypanosoma brucei, Trypanosoma cruzi) cause severe human diseases like leishmaniasis, African sleeping sickness, and Chagas disease.
These parasites exhibit unique gene expression mechanisms, including polycistronic transcription and trans-splicing.
Limited knowledge exists regarding the DNA sequences and proteins governing transcription initiation and termination in these organisms.

Purpose of the Study:

To review and comment on recent findings concerning transcription initiation and termination in trypanosomatid protozoa.
To highlight the role of identified proteins and epigenetic factors in trypanosomatid gene expression.

Main Methods:

In silico analyses of trypanosomatid genome databases.
Review of functional studies on transcription factors.
Examination of recent genome-wide studies on epigenetic regulation.

Main Results:

In silico analyses identified a limited number of proteins involved in gene expression.
Functional studies indicated a greater number of general transcription factors than initially estimated.
Epigenetic regulation, including histone modifications and variants, appears critical for gene expression.

Conclusions:

Transcription initiation and termination in trypanosomatids involve more complex mechanisms than previously thought.
Epigenetic regulation plays a significant role in trypanosomatid gene expression.
Further research is needed to fully elucidate these processes in parasitic protozoa.
