WebTLR9 is a receptor for microbial unmethylated cytosine-phosphate-guanosine (CpG) DNA ( 29, 30 ). TLRs contain an extracellular domain (ectodomain) comprising multiple leucine-rich repeats (LLRs), a cysteine-rich motif followed by a transmembrane region, and a highly conserved cytoplasmic toll/interleukin (IL)-1 receptor (TIR) domain. WebMay 15, 2004 · Treatment of highly purified activated CD4 (+) T cells with the dsRNA synthetic analog poly (I:C) and CpG oligodeoxynucleotides (CpG DNA), respective ligands for TLR-3 and TLR-9, directly enhanced their survival without augmenting proliferation. In contrast, peptidoglycan and LPS, respective ligands for TLR-2 and TLR-4 had no effect.
