Pigmentation01:19

Pigmentation

5.1K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Changes in Skin Color: Clinical Perspectives

4.2K
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...

Epistasis01:39

Epistasis

51.7K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

11.3K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Area of Science:

  • Dermatology
  • Cellular Biology
  • Regenerative Medicine

Background:

  • Burns frequently cause temporary or permanent skin pigment loss, affecting patient appearance.
  • Current treatments for post-burn pigment changes lack strong scientific backing and yield poor results.

Purpose of the Study:

  • To review the molecular and cellular basis of skin pigmentation.
  • To examine the mechanisms of skin repigmentation following burn injuries.
  • To discuss current and potential treatment options for pigmentary alterations and provide sun safety guidelines for burn patients.

Main Methods:

  • Literature review of scientific articles on skin pigmentation, burn healing, and treatment modalities.
  • Analysis of molecular and cellular pathways involved in melanogenesis and repigmentation.
  • Synthesis of evidence regarding the efficacy of various treatment interventions.

Main Results:

  • Skin pigmentation involves complex molecular and cellular processes, including melanocyte function and melanin transfer.
  • Repigmentation after burns is a multifactorial process influenced by residual melanocytes, stem cells, and inflammatory responses.
  • Many existing treatments for pigment changes have limited efficacy due to a lack of understanding of underlying mechanisms.

Conclusions:

  • A comprehensive understanding of pigmentation mechanisms is crucial for developing effective treatments for post-burn pigmentary changes.
  • Future research should focus on evidence-based therapies targeting specific molecular pathways to improve repigmentation outcomes.
  • Proper sun protection is essential for managing skin appearance and preventing further damage in burn survivors.
