Insights

MicroRNAs (miRNAs) play a key role in atopic dermatitis (AD) development. Specific miRNAs show potential as diagnostic markers and therapeutic targets for managing this chronic skin condition.

Area of Science:

  • Dermatology
  • Molecular Biology
  • Genetics

Background:

  • Atopic dermatitis (AD) is a chronic inflammatory skin disease.
  • AD pathogenesis involves skin barrier defects, immune system dysfunction, and genetic/environmental influences.

Purpose of the Study:

  • To review the latest findings on microRNA (miRNA) involvement in AD.
  • To explore the potential of miRNAs as diagnostic biomarkers and therapeutic targets for AD.

Main Methods:

  • Review of current scientific literature on miRNAs and AD.
  • Detailed analysis of specific miRNAs implicated in AD pathogenesis.
  • Discussion of molecular mechanisms and clinical relevance.

Main Results:

  • Several miRNAs, including miR-223, miR-10a-5p, miR-29b, and miR-146a-5p, are implicated in AD.
  • These miRNAs influence key pathways in AD pathogenesis.
  • Their expression levels correlate with disease severity and progression.

Conclusions:

  • MicroRNAs are critical players in the pathogenesis of atopic dermatitis.
  • Targeting specific miRNAs offers promising avenues for novel AD diagnostics and therapeutics.

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...

T Cell Types and Functions01:24

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...

Asthma: Pathogenesis and Management01:20

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
