Hybrid resequencing of the antibacterial innate immune genes coding for toll-like receptors, namely TLR1, TLR2, TLR4, TLR5, and TLR6, using HiSeq PacBio technologies pooled population samples Czech Simmental (Czech Red) cattle allowed us to determine haplotypes formed by polymorphisms present. Directly determined within range large proximal amplicon in TLR2 two clusters network tree graph. The ...

Acquired cholesteatoma is a chronic inflammatory disease characterized by both hyperkeratinized squamous epithelial overgrowth and bone destruction. Toll-like receptor (TLR) activation and subsequent inflammatory cytokine production are closely associated with inflammatory bone disease. However, the expression and function of TLRs in cholesteatoma remain unclear.We observed inflammatory cell in...

Toll-like receptors (TLR) are crucial for an efficient antifungal defense. We investigated the differential recognition of blastoconidia and hyphae of Candida albicans by TLRs. In contrast to Candida blastoconidia, which stimulated large amounts of gamma interferon (IFN-gamma), the tissue-invasive Candida hyphae did not stimulate any IFN-gamma by human peripheral blood mononuclear cells (PBMC) ...

OBJECTIVE The purpose of this study was to determine whether myeloid differentiation factor 88 (MyD88) and its related Toll-like receptors (TLRs) 2 and 4 contributed to the development of angiotensin II (AngII)-induced abdominal aortic aneurysms (AAAs) and atherosclerosis. METHODS AND RESULTS AngII was infused into either apoE(-/-) or LDL receptor (LDLR)(-/-) male mice that were either MyD88(...

OBJECTIVE Atherosclerosis encompasses a conspicuously maladaptive inflammatory response that might involve innate immunity. Here, we compared the role of Toll-like receptor 4 (TLR4) with that of TLR2 in intimal foam cell accumulation and inflammation in apolipoprotein E (ApoE) knockout (KO) mice in vivo and determined potential mechanisms of upstream activation and downstream action. METHODS ...

BACKGROUND Epidemiological studies have reported adverse effects of ambient air pollution on the prevalence of asthma. Laboratory studies have suggested that innate immune responses are involved. OBJECTIVE A study was undertaken to determine whether the Toll-like receptor 2 and 4 genes (TLR2 and TLR4) influence the susceptibility to adverse effects of traffic-related air pollution with respec...

OBJECTIVES Gastrointestinal disorders caused by Salmonella enterica serovar Enteritidis (SesE) are a significant health problem around the globe. Probiotic bacteria have been shown to have positive effects on the immune responses. Lactobacillus acidophilus was examined for its capability to influence the innate immune response of HT29 intestinal epithelial cells towards SesE. The purpose of thi...

Infection of epithelial cells by Cryptosporidium parvum triggers a variety of host-cell innate and adaptive immune responses including release of cytokines/chemokines and up-regulation of antimicrobial peptides. The mechanisms that trigger these host-cell responses are unclear. Thus, we evaluated the role of TLRs in host-cell responses during C. parvum infection of cultured human biliary epithe...
