Rabbit polyclonal antibodies to nuclear factor-kappa B (NF-[kappa]B) and TLR4 were from Novus (Novus, Littleton, CO, USA).
The expressions of HMGB1 and TLR4 were assessed by a commercial ELISA kit (Sangon Biotech, China) following the instructions of the manufacturer.
TLR2 SNP rs3804099 (T>C) and rs3804100 (T>C) and TLR4 SNP rs10759932 (T>C) were used in the present study.
In this study, it was analyzed whether the TLR4 Asp299Gly and Thr399Ile and TLR2 intron 2 gene polymorphisms caused a tendency for the development of acute biliary pancreatitis and whether there was a difference between patients in terms of these gene polymorphisms according to the imaging findings and recurrent disease.
TLR4 genotiplemesi, Asp299Gly ve Thr399Ile varyantlari icin Lightcycler (Roche Diagnostics, Mannheim, Germany) spesifik hibridizasyon problari kullanilarak tanimlandi (17).
Wang et al in the periodontal fibroblast cells showed that TLR4 and the activation of MAPK/JNK and MAPK/p38 were involved.19
Considering the notion that fluctuating hyperglycemia may exert more detrimental effects in patients with diabetes or other diseases, the aim of the present study is to compare the effects of persistent and of intermittent hyperglycemia on TLR4 and A-FABP expression and on the inflammatory response in THP-1 macrophages.
In order to determine the effect of inflammatory reactions in the pathogenesis of miscarriage, genotyping of promoter sites was carried out using the following polymorphic markers: G753A for TLR2; C399T for TLR4; G2848A for TLR9; C509T for TGF-[beta]1; PROGINS for PGR; G174C for IL-6; C781Tfor IL-8; C592A for IL-10; and G308A for TNF[alpha].
These sections were blocked with 5% bovine serum albumin for 20 minutes, incubated with primary antibody TLR4 (1: 500), MyD88 (1: 1000), and NF-[kappa]B (1: 1000) at 37[degrees]C for 1 hour, and washed two or three times with PBS.
Recognition of LPS by its receptor TLR4 results in production of a broad range of molecules, including proinflammatory cytokines, chemokines, reactive oxygen species, and upregulation of adhesion and costimulatory receptors [17].
TLR4 is binding with residues 89-108 of HMGB1 [42, 43], while RAGE is binding with residues 150-184 of HMGB1 [44].
