BACKGROUND Work from our laboratory has proven that increased titers of anti-heat shock protein 60 (HSP60) antibodies are associated with atherosclerosis and that HSP60-reactive T-cells are present in atherosclerotic lesions. Recent studies from others demonstrated that HSP60 directly activates endothelial cells and macrophages. METHODS AND RESULTS To explore the possibility that HSP60 exists...

Ninety male patients with acute nongonococcal urethritis (NGU) who presented for follow-up 10-92 days after initiation of treatment were evaluated. A polymerase chain reaction assay and direct fluorescence antibody test were used to detect Chlamydia trachomatis at presentation and during follow-up. Chlamydial heat-shock protein 60 kD (hsp60) serology with an enzyme-linked immunosorbent assay an...

Background: Recently, the incidence of allergic diseases has been on the rise; Dust mite is the major indoor allergen which needs a special consideration.Objectives: This study was carried out to identify and investigate the molecular properties of a new allergen named Hsp60 and to afford a foundation for future research of the allergic diseases caused by...

Abstract Background Circadian disruption is often associated with aggravation of atherosclerosis; however, the pathophysiological mechanisms underlying atherogenic initiation in normolipidemic diet remains unclear. Most studies done for understanding circadian induced atherosclerosis have been carried out murine model hyperlipidemia atherosclerosis. The present study investigates pro-atherogeni...

Polysaccharides extracted from Lycium barbarum (LBPs) possess a wide variety of biological activities. However, their neuroprotective effects have not yet been fully elucidated. The aim of the present study was to investigate the inhibitory effects of LBPs on the production of lipopolysaccharide (LPS)‑induced proinflammatory mediators in BV2 microglia. BV2 mouse microglial cells were cultured a...

We demonstrate that human T lymphocytes proliferate in vitro to highly purified human heat-shock protein 60 (Hu.hsp60). The response to this self Ag was confined to the CD45RA+ RO- T cell subset, with minimal responses by adult CD45RA- RO+ T cells. Experiments using keyhole limpet hemocyanin as a prototypic novel Ag, or tetanus toxoid as a recall Ag, were consistent with the notion that CD45RA+...

Mitochondrial functions play a central role in energy metabolism and provide survival fitness to both normal and tumor cells. Mitochondrial chaperonin Hsp60 is involved in both pro- and anti-apoptotic functions, but how Hsp60 senses the mitochondria selective oxidative stress response is unknown. In this study, by using rotenone, an irreversible inhibitor of oxidative phosphorylation against IM...

background: inflammation and infectious agents such as chlamydia pneumoniae have been associated with cardiovascular disease. objective: to evaluate the serum high sensitivity c - reactive protein (hs-crp) and antibodies against chlamydia pneumoniae and chlamydial heat shock protein-60 (cp-hsp60) in patients with ischemic heart disease (ihd). methods: 62 patients with ihd having either acute my...

Analysis of 16S rRNA gene sequences has been the method generally used to study the evolution and phylogeny of bacteria. Phylogenetic analysis of the 16S rRNA gene has shown the position of the genus Helicobacter in the epsilon-subclass of the Proteobacteria. Because 16S rRNA-based phylogeny does not always correspond to the results of polyphasic taxonomy, and the related species cannot always ...
