Summary
Non-coding RNAs, like microRNAs and long non-coding RNAs, regulate T cell exhaustion in chronic infections and tumors. Understanding these molecules can lead to better immunotherapies against viruses and cancer.
Area of Science:
- Immunology
- Molecular Biology
- Cancer Research
Background:
- T cell exhaustion impairs the immune response against chronic viral infections and tumors.
- Current immunotherapies like immune checkpoint inhibitors have limitations, including off-target effects and targeting single pathways.
Purpose of the Study:
- To review the roles and mechanisms of microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) in regulating T cell exhaustion.
- To highlight the potential of miRNAs and lncRNAs as molecular targets for improved immunotherapies.
Main Methods:
- Literature review focusing on studies investigating non-coding RNAs in T cell exhaustion.
- Analysis of mechanisms by which miRNAs and lncRNAs influence T cell function in chronic viral infections and cancer.
Main Results:
- Non-coding RNAs, including miRNAs and lncRNAs, are integral to the immune response in viral infections and cancer.
- These non-coding RNAs play significant roles in the development and regulation of T cell exhaustion.
Conclusions:
- Targeting specific non-coding RNAs could offer a more precise and effective approach to reversing T cell exhaustion.
- Further research into miRNAs and lncRNAs may pave the way for novel immunotherapeutic strategies against chronic viral diseases and tumors.

8.8K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

01:20Types of RNA

Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Before mRNAs are exported to the cytoplasm, it is crucial to check each mRNA for structural and functional integrity. Eukaryotic cells use several different mechanisms, collectively known as mRNA surveillance, to look for irregularities in mRNAs. Irregular or aberrant mRNA are rapidly degraded by various enzymes. If a defective mRNA escapes the surveillance, it would be translated into a protein which would either be non-functional or not function properly. One of the primary irregularities in...

5.7K
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.

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...
