Toll-like receptor (TLR) 2 is important in the innate immune response against both pathogens, and is therefore of interest in sarcoidosis research. In the present study, three single nucleotide polymorphisms and one dinucleotide repeat polymorphism in the TLR-2 gene were genotyped in 419 sarcoidosis patients, divided into a study cohort and a validation cohort, and 196 healthy controls. In the study cohort we found a significant increase in prevalence of the AA-genotype at promotor location \u221216934 in patients with chronic disease compared to patients with acute\/self-remitting sarcoidosis (34\u00b75% versus 15\u00b79%, respectively, P\u2003=\u20030\u00b7006, Pc\u2003=\u20030\u00b7019). These results could not be confirmed in our validation cohort, implicating a possible role for TLR-2 genetics in only a small percentage of sarcoidosis patients. Furthermore, linkage was found between the promotor polymorphism \u221216934\u2003A\/T and the number of GT repeats in intron 1 (P\u2003&amp;lt;\u20030\u00b70001). After in vitro stimulation of peripheral blood mononuclear cells (PMBCs) with different TLR-2 agonists, a correlation between induction of TNF-\u03b1 (P\u2003=\u20030\u00b7008), interleukin (IL)-12 (P\u2003=\u20030\u00b7008) as well as IL-6 (P\u2003=\u20030\u00b702), and the number of GT repeats was observed. In conclusion, the data show that polymorphisms in TLR-2 might be important in a small group of sarcoidosis patients and that their functional consequences explain partly some of the variance in cytokine pattern observed in different clinical phenotypes of this disease.<\/jats:p>","DOI":"10.1111\/j.1365-2249.2007.03428.x","type":"journal-article","created":{"date-parts":[[2010,8,12]],"date-time":"2010-08-12T14:07:47Z","timestamp":1281622067000},"page":"453-462","source":"Crossref","is-referenced-by-count":66,"title":["Linkage
