Background:
- MicroRNAs (miRNAs) are small, noncoding RNAs regulating gene expression post-transcriptionally.
- miRNAs are vital in biological processes including development, inflammation, and disease.
- Emerging research highlights miRNAs' significant role in immune system function.
Purpose of the Study:
- To summarize recent findings on miRNA functions in immunity.
- To explore the mechanisms by which miRNAs modulate immune responses.
- To provide an overview of miRNAs in innate and adaptive immunity.
Main Methods:
- Literature review of recent studies on miRNAs and immunity.
- Analysis of miRNA involvement in immune cell development and differentiation.

01:22MicroRNAs
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 ends...

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...

01:29Immune Response Against Viral Pathogens
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
