実施例1
ニワトリTLR21の遺伝子クローニングおよび非相同発現
ニワトリTLR研究における最近の進展により、TLR21が、鳥種において、哺乳類TLR9の機能的相同体であることが示唆されている(Keestra 2008、Brownlieら 2009)。
Genbankデータベース配列NM_001030558に基づいて、プライマーペアを、ニワトリTLR21遺伝子のポリメラーゼ連鎖反応(PCR)増幅用に合成した:
Ga−TLR21−for1
GAAGCTT(ACC)[ATG]ATGGAGACAGCGGAGAAGGC
Ga−TLR21−rev1
GGCGGCCG[CTA]CATCTGTTTGTCTCCTTCCCTG
プライマーは、フランキング位置制限クローニング部位(下線)、ならびにコザック配列(丸括弧)、開始コドンおよび終止コドン(角括弧)を与えるように設計した。これらのプライマーおよびテンプレートとしてニワトリ脾臓総RNAを用いて、RT−PCRを実行した。予想されるサイズ(約3000bp)のPCR産物を、pCR2.1−Topo内にクローン化し、5つの独立したプラスミドクローン(P1、P2、P12、P13、P14)を配列決定した。
ヒト胚腎臓(HEK)細胞293は、1970年代にウイルストランスフォーメーション(Grahamら,1977)によって生み出されたものであり、現在、細胞系リポジトリ(ATCC等)を経由して、研究コミュニティが利用できるものである。
モチーフ5’[G]x{TCGTCG}nTCG[G]z 3’に基づくこの一連のホモポリマーにおいて、3’−dGランを、試験した全てのODNについて、1Gにまで短くした。

モチーフ5’[G]x{TCGTCG}nTCG[G]z 3’に基づくこの一連のホモポリマーにおいて、n=4のまま、3’−Gの数を変えた。

図10は、リポータ細胞HEK293−pNifty2−chickenTLR21におけるリポータ酵素SEAPの有色産物量(405nmで吸光する)を誘導する際の、3’−Gの数を変えた効果を示す。

X23−nine−3455(n=4、x=5、z=4) <<100pM
X23−nine−3451(n=4、x=5、z=0) <<100pM
この結果から、3’−Gの数は、z=4または4未満であるならば、EC50に特に関連しないと推論することができる。
