Summary
Mammalian microRNAs (miRNAs) regulate gene expression and are key to immune cell function. Dysregulated miRNA expression links to immune diseases like cancer and autoimmunity, offering diagnostic potential.
Area of Science:
- Immunology
- Molecular Biology
- Gene Regulation
Background:
- MicroRNAs (miRNAs) are crucial post-transcriptional gene regulators in mammals.
- miRNAs exhibit distinct expression patterns within innate and adaptive immune cells.
- Their roles in immune cell development and function are increasingly recognized.
Purpose of the Study:
- To review recent advancements in understanding miRNA functions in immune cell biology.
- To explore the pathological roles of dysregulated miRNA expression in immune-related diseases.
- To highlight the diagnostic and prognostic potential of miRNAs in immunology.
Main Methods:
- Literature review of recent studies on miRNA function and dysregulation in immunology.
- Analysis of miRNA expression profiles in immune cells.
- Investigation of miRNA involvement in immune cell development and function.
- Examination of miRNA roles in immune system pathologies like cancer and autoimmunity.
Main Results:
- miRNAs are pivotal regulators of both innate and adaptive immune cell development and function.
- Aberrant miRNA expression is implicated in immune system disorders, including cancer and autoimmune diseases.
- miRNAs show promise as biomarkers for disease diagnosis and prognosis.
Conclusions:
- miRNAs are essential for normal immune system operation.
- Dysregulation of miRNAs contributes significantly to immune pathology.
- miRNAs represent valuable targets and biomarkers for immune-related diseases.

MicroRNAs
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Immune Surveillance by NK Cells and Phagocytes
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

NF-κB-dependent Signaling Pathway
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Human Virome
The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...
