Summary
This review examines how Leishmania parasites alter host gene expression in macrophages. Understanding these changes in macrophage models advances our knowledge of leishmaniasis and may reveal future therapeutic targets.
Area of Science:
- Immunology
- Genomics
- Parasitology
Background:
- High-density microarray technology enables global host gene expression analysis.
- Numerous studies since 2001 have explored Leishmania infection effects on host cells.
- Macrophages are key immune cells involved in the host response to Leishmania.
Purpose of the Study:
- To review transcriptional changes in macrophage models induced by various Leishmania species.
- To summarize the impact of these studies on understanding in vitro host response to leishmaniasis.
- To identify potential therapeutic targets for leishmaniasis.
Main Methods:
- Literature review of peer-reviewed publications on Leishmania and host gene expression.
- Analysis of microarray data from various macrophage models.
- Comparative characterization of different experimental systems.
Main Results:
- Compilation of host gene expression profiles in response to Leishmania infection.
- Identification of conserved and divergent transcriptional responses across different Leishmania species and models.
- Summary of key pathways and cellular processes affected by Leishmania.
Conclusions:
- Transcriptional profiling provides critical insights into host-pathogen interactions in leishmaniasis.
- Comparing different macrophage models highlights the nuances of the host response.
- Further understanding of Leishmania-induced gene expression changes can guide therapeutic strategies.

Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

What is Gene Expression?
11.4K
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...

Cell Specific Gene Expression
16.5K
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Chromatin Position Affects Gene Expression
24.8K
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.

mRNA Stability and Gene Expression
6.6K
The structure and stability of mRNA molecules regulates gene expression, as mRNAs are a key step in the pathway from gene to protein. In eukaryotes, the half-life of mRNA varies from a few minutes up to several days. mRNA stability is essential in growth and development. The absence of the proteins regulating its stability, such as tristetraprolin in mice, can cause systemic issues, including bone marrow overgrowth, inflammation, and autoimmunity.
