초록

선모충(Trichinella spiralis)은 감염 후 nurse cell 형성과정에서 영양분 공급 및 배설을 위해 혈관신생인자인 vascular endothelial cell growth factor (VEGF)를 유도하여 혈관신생을 촉진한다. 하지만 이러한 과정 중 선모충이 어떻게 VEGF의 발현을 유도하는지에 대해서는 아직 밝혀지지 않았다. Nurse cell 형성 과정에서 저산소현상이 발생되고 이러한 저산소 현상이 VEGF의 발현을 유도할 것이라는 제안이 있지만 실제 nurse cell 형성 과정에 저산호 현상이 일어나는지도 조사되지 않았으며 저산소 현상이 실제 VEGF를 통한 혈관신생을 유도하는지도 규명되지 않았다. 최근 연구결과에 의하면 VEGF의 발현을 유도하는 티모신베타4 단백질이 초기의 선모충 감염 nurse cell에서 강력하게 유도되는 것이 관찰되었다. 게다가 저산소 현상이 nurse cell 형성 과정에서 관찰되지 않았고 면역세포들이 응집되어 있는 파괴되는 nurse cell에서만 관찰되는 것이 밝혀졌다. 이러한 결과는 티모신베타4가 저산소 현상과 무관하게 선모충 감염 nurse cell에서의 VEGF 유도 및 혈관신생을 유도할 가능성을 제시해 준다.
