연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

Nucleotide metabolism in endothelium is variable between different species. Recent studies demonstrated that this variability could contribute coagulation dysfunction, even though organs of the alpha 1,3-galactosyltransferase gene knockout pig were transplanted into the primate. CD73 (ecto-5'-nucelo...

문제 정의

  • 본 연구에서 혈관내피세포에서 특이적으로 발현하는 돼지의 Intercellular adhesion molecule2(Icam2) 프로모터에 CD73유전자를 연결한 pIcam2-CD73 발현벡터를 제작하였다. 상기벡터를 돼지에서 추출한 초기 섬유아세포와 혈관 내피세포에 도입시킨 후 발현을 분석한 결과 CD73은 혈관 내피세포에서만 특이적으로 발현되는 것을 확인하였다.

질의응답

핵심어 질문 논문에서 추출한 답변
퓨린 신호전달은 어떤 과정인가? 혈액에서 ATP가 아데노신으로 분해되는 과정인 퓨린 신호전달(purinergic signaling) 경로에는 핵산 분해효소인 CD39도관여하여 ATP를 adenosine 5’-driphosphate(ADP), adenosine 5’-monohosphate(AMP)로 분해시킨다. 특히 CD39는 핵산 분해효소 중에서 다른 효소들과 비교하였을 때 가장 효과적으로 CD73과 상호작용을 한다고 보고되고 있다(Fausther et al.
분해된 아데노신은 어떤 기능이 있는가? , 1986; Zimmermann, 1992). 분해된 아데노신은 세포보호 기능, 면역억제 기능, 혈소판 활성억제의 생리 및 약리적 특성을 갖고 있다 (Daval et al., 1991; Delikouras et al.
돼지 장기를 영장류에 이식하게 되면 초급성 면역거부반응이 발생할 수 있는데 이를 극복하기 위해 무엇을 하였는가? 돼지의 장기를 영장류에 이식하게 되면 초급성 면역거부반응이라고 알려진 거부반응이 이식된 장기에서 발생한다(Yang and Sykes, 2007). 이러한 문제점을 극복하기 위하여 이 반응의 원인 유전자인 α1,3-Galactosyltransferase(GalT)의 기능이 제거된 돼지(knock out, KO)가 생산되었고(Kolber-Simonds et al., 2004; Nottle et al.
