Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

7.0K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

Changes in Skin Color: Clinical Perspectives

2.1K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Area of Science:

  • Immunodermatology
  • Molecular Biology
  • Biochemistry

Background:

  • Atopic dermatitis (AD) is a chronic inflammatory skin disease with immune dysregulation and barrier defects.
  • Post-translational modifications (PTMs) are crucial in regulating protein function and implicated in inflammatory conditions.
  • The specific roles of PTMs in AD pathogenesis remain under-explored.

Purpose of the Study:

  • To review the current understanding of major PTMs in atopic dermatitis (AD).
  • To explore the involvement of PTMs in the immune system and skin barrier disruption in AD.
  • To discuss potential therapeutic strategies targeting PTMs for AD management.

Main Methods:

  • Literature review of studies on PTMs and atopic dermatitis.
  • Analysis of six major classes of PTMs: phosphorylation, acetylation, ubiquitination, SUMOylation, glycosylation, and glycation.
  • Synthesis of findings related to PTMs' impact on AD pathogenesis.

Main Results:

  • PTMs significantly influence immune cell function and inflammatory signaling in AD.
  • Disruptions in PTMs contribute to skin barrier abnormalities observed in AD.
  • Specific PTM pathways like phosphorylation and ubiquitination are key players in AD inflammation.

Conclusions:

  • PTMs play a critical, multifaceted role in the pathogenesis of atopic dermatitis.
  • Targeting specific PTMs presents a promising therapeutic avenue for AD treatment.
  • Further research into PTMs is essential for developing novel AD management strategies.
