The enhanced synthesis of a few proteins immediately after subjecting cells to a stress such as heat shock was first reported for drosophila cells in 1974 (l), and the universality of the response from bacteria to human was recognized shortly thereafter (reviewed in Ref. 2). In the ensuing 16 years, a vast literature has accumulated that describes a wide variety of events in a cell’s response t...

The small heat-shock proteins have undergone a tremendous diversification in plants; whereas only a single small heat-shock protein is found in fungi and many animals, over 20 different small heat-shock proteins are found in higher plants. The small heat-shock proteins in plants have diversified in both sequence and cellular localization and are encoded by at least five gene families. In the st...

This article provides an insight towards the various applications of heat shock proteins and also gives a brief introduction, discovery & functions of heat shock proteins. An overview of role of heat shock proteins in cardiovascular disease, infectious diseases & in cancer is discussed. Heat shock proteins, a family of stress inducible proteins are involved in the pathogenesis of atheroscleroti...

An infectious virus isolated from the cultured Drosophila melanogster cell line, Schneider 2-L, appears to be a member of a new group of animal viruses. The virus, HPS-1 has a genome composed of a single segment of double-stranded RNA approximately 6 kb in length. Virions are particles approximately 36 nm in diameter. They contain only two proteins and no lipid coat. The major protein, presumab...

Bacterial and viral triggers are suspected agents in the initial etiology of autoimmune diseases. There are some studies on the etiology of autoimmune disorders which have focused on streptococcal infection and a possible relation with microbial heat shock proteins (hsp) which show significant homology with human heat shock proteins. In addition, some serotypes of streptococci cross-react ...

KEY WORDS heat shock proteins; cytokines; heat shock factor t has become clear in recent years that, heat shock proteins (hsps) play a major role in the acute in-flammatory response and inflammatory diseases. 1,z Heat shock proteins were originally characterized as a highly conserved group of proteins involved in the response of cellular organisms to stresses such as heat shock. 3,4 These prote...

In recent years, it has become clear that, in addition to the regulation of the expression of specific genes, there are global regulatory systems that control the simultaneous expression of a large number of genes in response to a variety of environmental stresses. The first of these global control systems, and of substantial importance, is the heat-shock response. The heat-shock response is ch...
