Insights

MicroRNAs (miRNAs) regulate gene expression and are key in psoriasis pathogenesis. Circulating miRNAs show potential as diagnostic biomarkers and therapeutic targets for this inflammatory skin condition.

Area of Science:

  • Molecular Biology
  • Immunology
  • Dermatology

Background:

  • Psoriasis is an inflammatory skin disease involving keratinocyte dysfunction and immune dysregulation.
  • MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression post-transcriptionally.

Purpose of the Study:

  • To review the roles of miRNAs in the pathogenesis of psoriasis.
  • To explore the potential of miRNAs as biomarkers and therapeutic targets for psoriasis.

Main Methods:

  • Literature review of recent studies on miRNAs and psoriasis.
  • Analysis of miRNA involvement in keratinocyte function and immune responses in psoriasis.

Main Results:

  • miRNAs significantly regulate keratinocyte hyperproliferation and cytokine/chemokine production in psoriasis.
  • miRNAs are implicated in the immune dysfunction characteristic of psoriasis.
  • Circulating miRNAs may serve as biomarkers for psoriasis diagnosis, therapy monitoring, and disease severity.

Conclusions:

  • miRNAs play critical roles in psoriasis development and progression.
  • Targeting specific miRNAs offers a promising avenue for novel psoriasis therapeutics.
  • Circulating miRNAs represent valuable biomarkers for clinical management of psoriasis.

T Cell Types and Functions

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.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

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...
