background permanent antigenic variation of influenza viruses causes a major concern to develop an effective human influenza vaccine. conserved antigens are new vaccine candidates because it is not necessary to match the prepared vaccine with circulating strains. ion channel m2 protein is conserved among all influenza a viruses, allowing the virus to enter host cells. objectives to prepare an e...
Protein-damaging stresses, including heat shock, cold, altered pH and oxygen deprivation induce the expression of a subgroup of molecular chaperones, called heat shock proteins (Hsp), which consist of several protein families designated by their molecular weight, such as the Hsp90, Hsp70, Hsp60, and the small Hsp (sHsp) families. Small heat shock proteins (sHsp) with a molecular mass of 15–30 k...
Brief periods of ischemia not only cause a long lasting (hours to days) myocardial contractile dysfunction (stunning) but also increase the tolerance for irreversible damage during a subsequent ischemic episode, a phenomenon called ischemic preconditioning.1J Heat-shock proteins, in particular HSP-70, have been postulated in myocardial protection against irreversible damage due to i~chemia .~ I...
An antibody highly specific for heat-shock protein (hsp)26, the unique small hsp of yeast, and mutants carrying a deletion of the HSP26 gene were used to examine the physical properties of the protein and to determine its intracellular distribution. The protein was found in complexes with a molecular mass of greater than 500 kD. Thus, it has all of the characteristics, including sequence homolo...
The heat shock response (HSR) refers to the rapid production of heat shock proteins (hsps) in response to a sudden increase in temperature. Its regulation by heat shock factors is a good example of how gene expression is transcriptionally regulated by environmental stresses. In contrast, little is known about post-transcriptional regulation of the response. The heat shock response is often used...
Is Low-Heat Shock Protein 70 a Primary or a Secondary Event in the Development of Atherosclerosis? Letter to the Editor: Pockley et al’s landmark observation that serum heat shock protein (Hsp) 70 levels predict the development of atherosclerosis1 prompts the question whether Hsp 70 is low as a result of atherosclerosis or the primary event leading to atherosclerosis. We believe an argument can...
The 25-kD inhibitor of actin polymerization (25-kD IAP), isolated from turkey smooth muscle (Miron, T., M. Wilchek, and B. Geiger, 1988. Eur. J. Biochem. 178:543-553), is shown here to be a low molecular mass heat shock protein (HSP). Direct sequence analysis of the purified protein, as well as cloning and sequencing of the respective cDNA, disclosed a high degree of homology (67% identity, 80%...
Aging and pathophysiological conditions are linked to membrane changes which modulate membrane-controlled molecular switches, causing dysregulated heat shock protein (HSP) expression. HSP co-inducer hydroxylamines such as BGP-15 provide advanced therapeutic candidates for many diseases since they preferentially affect stressed cells and are unlikely have major side effects. In the present study...
We have identified by differential plaque hybridization, human cDNA clones encoding a member of a heat-shock protein family (hsp 90 alpha) in the cDNA library of Adenovirus Type 12 E1A transfected HeLa cells. The complete nucleotide sequence of one of the clones (pHB76-114A) was identified. The sequence of 2912 base pairs had a single reading frame with a coding potential for an 84,672-Da prote...
Neurotropism is one of the most important characteristics of Mycobacterium leprae (M. leprae). It is believed that nerve damage of leprosy is caused by various immune mechanisms 1), and so called "autoimmune reaction" is suspected to have one of the role in nerve damage. M. leprae 65 kDa heat shock protein (hsp 65) has noticeable characteristics. Hsp 65 is a highly conserved protein2). It belon...
