Abstract

In the last few years, a spectrum of dendritic cells(DCs), including toll like receptors(TLRs), might play a critical role in regulating allergy and asthma. DC plays a central role in initiating immune responses, linking innate and adaptive responses to pathogen. Human peripheral blood has three non-overlapping dendritic subset that expressed various 11 TLRs. These dendritic subsets and TLR contribute significant polarizing influences on T helper differentiation, but how this comes about is less clear. A better understanding of DC immunobiology may lead to the comprehension of allergy pathophysiology to prevent early stage allergic march.

지난 5년간 Th1/Th2 기전을 보다 자세히 이해할 수 있는 면역연구분야로서 조절 T세포와 수지상세포에 관련된 연구가 많아졌다. 이중 내재면역과 적응면역의 고리 역할을 하는 수지상세포는 다양한 방법을 통해서 Th1/Th2 면역반응을 유도한다. 이에는 수지상 세포 자체의 성질(DC1;Th1/DC2;Th2)과 TLR 수용체 종류(TLR9;Th1/TLR2;Th2) 등에 따라 결정된다. 앞으로 항원제시방법, 세포내 신호전달방법과 더불어 태내부터 감작되는 알레르겐이 내재면역계에 어떻게 영향을 미치는가에 대한 폭넓은 연구가 필요한 상태이다.
