results the tlr3 protein in the ach group tended toward reduction although the p value of the comparison between the ach group and hd group was not statistically significant. the tlr3 levels in the hcc, ac, and cir groups were higher than those in the hd and ach groups. tlr3 was not interrelated with all costimulation proteins in the dcs and t cells in all five groups. no group presented any in...

multiple sclerosis (ms) is an autoimmune disease of central nervous system. since different types of immune cells are involved in ms pathogenesis, in this study we aimed to evaluate serum levels of several immunological components including soluble cd4 (scd4), scd8, scd163, and immunoglobulins as markers of activity of t-cells, macrophages, and b-cells in different types of ms. serum levels of ...

A method for obtaining highly purified endotoxin (lipopolysaccharide [LPS]) in a few hours by repurification of commercial or laboratory preparations was devised. It avoids the use of phenol, which is not suitable for phenol-soluble lipopolysaccharides nor for some industrial purposes. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and matrix-assisted laser desorption ionization mass...

BACKGROUND Most Alzheimer's disease (AD) cases arise sporadically and may involve innate immune activation of microglial expressed Toll-like receptors regulated through the myeloid differentiation protein 88 (MyD88) pathway. OBJECTIVE It was the aim of this study to test the innate immune involvement in AD pathology. METHODS We mated APPsw/PS1ΔE9 mice with MyD88-deficient mice. RESULTS Pr...

Introduction TREM-1 (Triggering Receptor Expressed on Myeloid Cells) amplifies Toll-like receptor (TLR) responses and is a putative biomarker to diagnose VAP. It exists on the surface of monocytes/macrophages (mTREM-1) and neutrophils (nTREM-1) as well as a soluble receptor (sTREM-1). Standalone levels of mTREM-1 in bronchoalveolar lavage fluid (BALF) and its BALF/blood ratio are elevated in VA...

PURPOSE ST2 receptor, which is a member of the Toll-like/interleukin-1 (IL-1) receptor family, has been found to be increased in the serum of patients 1 day after myocardial infarction. Several other studies have shown that soluble ST2 levels correlate with severity of heart failure (HF), left ventricular ejection fraction, creatinine clearance, B-type natriuretic peptide and C-reactive protein...

Dysregulation of the initial, innate immune response to bacterial infection may lead to septic shock and death. Toll-like receptors (TLRs) play a crucial role in this innate immune response, and yet the regulatory mechanisms controlling microbial-induced TLR triggering are still to be fully understood. We have therefore sought specific regulatory mechanisms that may modulate TLR signaling. In t...
