Summary
RNA processing, including alternative splicing and mRNA stability, fine-tunes innate immunity. RNA-binding proteins (RBPs) significantly regulate these RNA processing events, impacting immune responses.
Area of Science:
- Molecular Biology
- Immunology
- Genetics
Background:
- Protein expression is crucial for cellular function, yet regulated by complex RNA processing events.
- Innate immunity research traditionally focuses on transcription factors, overlooking RNA processing's role.
- RNA-binding proteins (RBPs) are increasingly recognized for their regulatory functions in gene expression.
Purpose of the Study:
- To review the impact of RNA processing on innate immunity.
- To describe the RBPs and mechanisms involved in regulating innate immune responses.
- To identify unanswered questions in the field of RNA processing and innate immunity.
Main Methods:
- Literature review of studies on RNA processing in innate immunity.
- Analysis of the roles of RBPs and their mechanisms in immune regulation.
- Synthesis of current knowledge and identification of research gaps.
Main Results:
- Alternative polyadenylation and mRNA stability control protein expression levels and duration.
- Alternative splicing dictates protein identity and function, impacting immune pathways.
- RBPs significantly contribute to the fine-tuning of the innate immune response through RNA processing.
Conclusions:
- RNA processing is a critical, understudied layer of regulation in innate immunity.
- RBPs are key players in modulating immune responses via RNA processing.
- Further research is needed to fully elucidate the mechanisms and therapeutic potential.

01:23Types of RNA
Overview
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 the regulation of 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.

01:23RNA Interference
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

02:41Chromatin Structure Regulates pre-mRNA Processing
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.

01:23Regulation of Expression at Multiple Steps
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the addition of a...
01:29Translational Regulation
Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...
