표피의 구성 요소는? | 피부의 가장 표면층인 표피는 각질세포, 모낭, 멜라닌세포, 랑겔한스 세포로 이루어져 있으며 피부의 중요한 기능 중 하나인 외부환경으로 부터 신체를 보호하는 역할과 내부 체액의 소실을 막는 장벽기능을 제공하는 것이다(Ishida 등, 2008). 피부장벽 기능이 피부 내외부의 다양한 자극에 의해 손상되면 피부가 건조해 지거나 가려움 및 염증반응을 일으키게 된다(Denda 등, 1996; Goldstein와 Abramovits 2003; Welss 등, 2004; Lynde 2008; Yeom 등, 2012). | |
피부의 역할은? | 피부의 가장 표면층인 표피는 각질세포, 모낭, 멜라닌세포, 랑겔한스 세포로 이루어져 있으며 피부의 중요한 기능 중 하나인 외부환경으로 부터 신체를 보호하는 역할과 내부 체액의 소실을 막는 장벽기능을 제공하는 것이다(Ishida 등, 2008). 피부장벽 기능이 피부 내외부의 다양한 자극에 의해 손상되면 피부가 건조해 지거나 가려움 및 염증반응을 일으키게 된다(Denda 등, 1996; Goldstein와 Abramovits 2003; Welss 등, 2004; Lynde 2008; Yeom 등, 2012). | |
cyclooxygenase-2의 특징은? | 피부의 염증반응은 여러 가지 복합적인 유전자들에 의해 조절되며 주요한 유전자로 cyclooxygenase-2 (COX-2)와 inducible nitric oxide synthases (iNOS)가 알려져 있다(Aktan 2004; Hur 등, 2010). 그 중 COX-2는 염증 유발 사이토카인, 세포성장인자, 암세포촉진인자, 활성산소종(reactive oxygen species, ROS) 등에 의한 PGE 2 생성과 건선, 마름버짐, 홍반성 낭창과 같은 염증성 피부질환을 유발하는 것으로 밝혀져 있다(Masferrer 등, 1994; Seibert 등, 1994; Hong 등, 2002; Jean 등, 2008). 또한, 각질세포 외막과 케라틴 중간 미세섬유를 연결하는 중요한 역할을 하는 단백질 중 하나인 filaggrin은 최근 아토피피부염의 유전적 소인 중 하나로 주목을 받고 있다. |
