背景:
- 人間の皮膚の微生物群の正確な分類と機能的分析には,強力な参照ゲノムが必要です.
- 既存の微生物ゲノムカタログは,ヒトの皮膚の微生物群に関する包括的な研究には不十分である.
研究 の 目的:
- 統合されたヒト皮膚微生物群ゲノム (HSMG) とタンパク質 (HSMP) のカタログを作成する.
- 開発されたカタログを使用して,平原の成人のヒト皮膚の微生物群を特徴づける.
- 皮膚の微生物の組成に影響を与える要因を特定する.
主な方法:
- 新たに配列を決定した739個のヒト皮膚サンプルと,公表された2520個のヒト皮膚サンプルを統合したものです.
- 2つの出版された微生物ゲノムカタログを組み込み,HSMGとHSMPを構築する.
- 種識別とタンパク質特徴付けのためのHSMGとHSMPのバイオ情報分析.
- 皮膚のタイプと習慣に基づいて,平原の成人の皮膚微生物群の特徴の比較分析.
主要な成果:
- HSMGは3,547のプロカリオット種を構成しており,その43.87%が未確認である.
- HSMPには3900万以上の非冗余タンパク質が含まれており,その64.8%の特徴が不十分です.

Skin Cancer
6.0K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Sensory Functions of the Skin
8.4K
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

Skin Diseases and Disorders
5.6K
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...

Role of Skin in Vitamin D Synthesis
8.0K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Accessory Structures of the Skin: Nails
3.4K
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

Changes in Skin Color: Clinical Perspectives
3.8K
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...
