Background—Recent evidence has implicated Chlamydia pneumoniae in the aggravation of atherosclerosis. However, the mechanisms by which this agent affects atherogenesis remain poorly understood. Chlamydiae produce large amounts of heat shock protein 60 (HSP 60) during chronic, persistent infections, and C pneumoniae localizes predominantly within plaque macrophages. Several studies have furnishe...

Hsp 60 is a chaperonin protein, homologous to GroEL of Escherichia coli and highly conserved across species. Immune response induced by the hsp 60 equivalent of numerous microorganisms elicits in animals and man a dominant cross-reactive T lymphocyte response. Hsp 60 has been strongly implicated as an example of molecular mimicry in the pathogenicity of autoimmune diseases and, more recently, i...

Henoch-Schönlein purpura (HSP) is the most common small vessel vasculitis of childhood. It is characterized by nonthrombocytopenic palpable purpura, abdominal pain, arthritis, and glomerulonephritis. Although HSP is typically known to be self-limited, serious complications can occur. Acute pancreatitis rarely presents as a complication of HSP. It is even rarer as an initial presenting feature o...

The book Heat Shock Proteins (HSP) in Cellular Communication and Signaling Volume 26 provides the most comprehensive highlight insight of expression, function therapeutic activity HSP signaling pathways. Using an integrative approach to understanding various HSP-mediated pathways response a variety stressors including hyperthermia, or metabolic changes produced by physical exercise psychologica...

The stress response is one mechanism that the bladder urothelium could potentially employ to protect itself from cellular damage after exposure to arsenic and, in so doing, influence the shape of the dose-response curve at low concentrations of exposure to this environmental pollutant. In the present study, we used the cultured human urothelial cell line UROtsa, a model of human urothelium, to ...

Introduction: Henoch schonlein purpura (HSP) is a self-limited systemic disease with multiorgan involvement. While cutaneous involvement may wary, presenting as itching papules is not a common manifestation. In this report we discuss a case of HSP which was presented solely with itching papules; mistaken for scabies. Case presentation: A 7 year old boy presented with itchy palpable papules with...

Introduction: Henoch-Schönlein purpura (HSP) is the most common vasculitis of childhood. The classic triad of HSP consists of nonthrombocytopenic purpura, arthritis/arthralgia, and gastrointestinal complaints. Pulmonary hemorrhage and cardiac involvement are rare complications of HSP. Case Report: We report the case of a 10-year-old girl with HSP complicated by both severe mitral regurgitation ...

We previously reported that endothelin-1 (ET-1) activates p42/p44 mitogen-activated protein (MAP) kinase in osteoblast-like MC3T3-E1 cells and consequently induces synthesis of interleukin-6. In the present study, we investigated the effect of ET-1 on the induction of heat shock protein 27 (HSP 27) in MC3T3-E1 cells. ET-1 time and dose dependently stimulated HSP 27 accumulation. ET-1 induced an...
