Summary
Regulatory B cells lack unique markers, identified by IL-10 production. Gene expression analysis using RT-qPCR, microarrays, and other technologies aids in characterizing these important immune cells.
Area of Science:
- Immunology
- Cell Biology
Background:
- Regulatory B cells (Bregs) are crucial for immune homeostasis.
- Bregs lack exclusive lineage markers, making their identification challenging.
- Efficient interleukin-10 (IL-10) production is the primary distinguishing feature of Bregs.
Purpose of the Study:
- To describe gene expression analysis techniques for regulatory B cells.
- To provide a guide for characterizing IL-10-producing B cells.
Main Methods:
- Review of gene expression profiling technologies.
- Discussion of targeted (RT-qPCR) and comprehensive (microarrays, Nanostring nCounter, Biomark HD) methods.
- Application of these techniques to regulatory B cell research.
Main Results:
- No single marker defines regulatory B cells.
- Multiple gene expression technologies are available for Bregs characterization.
- Choice of technology depends on the scope of gene expression analysis.
Conclusions:
- Regulatory B cells are functionally defined by IL-10 secretion.
- Gene expression profiling is essential for understanding Bregs.
- Available technologies offer diverse approaches for Bregs research.

1.2K
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...

3.9K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

02:24Regulation of Expression Occurs at Multiple Steps
24.6K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

02:23Master Transcription Regulators
7.4K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

8.1K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...
