Skin Diseases and Disorders

4.1K
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...

Olfactory Receptors: Location and Structure

9.6K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Accessory Structures of the Skin: Hair and Hair Follicles

2.7K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Allergic Drug Reactions

972
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Restless Leg Syndrome and Night Terrors01:27

Restless Leg Syndrome and Night Terrors

249
Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. These sensations typically occur during periods of rest or inactivity, particularly when lying down or sitting, and can severely disrupt sleep.
The exact cause of RLS is not fully understood, but it is believed to involve dopamine, a neurotransmitter that helps regulate muscle movement. Imbalances in dopamine levels...

科学分野:

  • 神経科学
  • 皮膚科
  • かゆみ 研究

背景:

  • アロクネシス 軽い触りなどで発症しないものから発症するは 慢性的なを患っている患者に重大な負担を科します
  • 主にアトピー性皮膚炎で観察されるこの症状は,様々な慢性的な障害で診断が不十分である可能性が高い.
  • 現在の診断は フォン・フレイ繊維のような方法に依存し 検証されたアンケートがない

研究 の 目的:

  • アロクネシスの基礎となる神経生理学的メカニズムを明らかにする.
  • アロクネシスを生理学的メカニカルなと区別する.
  • アロクネシスの治療戦略と臨床調査の必要性を強調する.

主な方法:

  • かゆみの経路,感受性,およびメカニカレプターに関する既存の文献のレビュー.
  • アロクネシスにおけるメカニカルラベル経路とポリモダル経路の役割の分析.
  • PIEZO1 と神経信号 (GRP/GRPR) のような分子プレーヤーの調査.

主要な成果:

  • アロクネシスは,生理学的メカニカルなとは異なり,の感受性に関連した病理的現象である.
  • 低値機構受容体 (LTMR) と脊髄内ニューロンを含む外周感受化が重要な役割を果たします.
  • メカニカルラベルとポリモダル経路の両方が貢献し,GRP/GRPR経路に収束します.

結論:

  • アロクネシスには,周辺的および潜在的に中心的な感受性メカニズムとの複雑な相互作用が含まれます.
  • 二重経路の関与 (メカニカルラベルとポリモダル) を理解すると,かゆみの伝達に関する洞察が得られます.
  • アロクネシスの減少は治療目標であり,さらなる研究と臨床試験の調査が必要である.
