background: heat shock proteins (hsp) are highly conserved molecules with many immunological functions. they are highly immunogenic with important role in cancer immunotherapy and in vaccine development against infectious diseases. as adjuvant, hsp can augment the immunogenicity of weak antigens and can stimulate antigen presenting cells. although vaccines have been successful for many infectio...
Background & Aim: Brucella is one of the most important zoonotic diseases and is caused by the members of Brucella genus especially B. melitensis. The bacteria begin to synthesize heat shock proteins(hsp) when facing elevated temperatures. In this investigation, clinical isolates of B. melitensis were subjected to heat shocks and the hsps produced were surveyed by SDS-PAGE electrophoresis. ...
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 ...

Introduction: The present study aimed to explore protective mechanisms of hypothermia against mild cold and heat stress on highly proliferative homogeneous human Neural Precursor Cells (NPCs) derived from Subventricular Zone (SVZ) of human fetal brain. Methods: CD133+ve enriched undifferentiated and differentiated human NPCs were exposed to heat stress at 42°C. Then, Western-blot qua...
The family of small heat shock proteins is the more variable among the highly conserved superfamily of heat shock proteins (HSP). Using a metabolic labeling procedure with tissue explants, we have detected in chickens a new member of the small HSP family with an apparent molecular weight of 29-kDa. This protein was induced in broiler chickens' heart muscle and lungs following an in vivo heat st...
Xenopus cells express two major proteins on heat shock, designated hsp 70 and hsp 30. Several cDNA clones for the corresponding mRNAs were identified and sequenced. Inducibility and abundance of heat shock mRNAs in various cell types and developmental stages was determined by nuclease S1-mapping. The only cells found to contain hsp 70 mRNA without heat shock are the oocytes. The level of this s...
Normal bone marrow progenitors and some leukemic cells develop only a limited amount of thermotolerance. Further, once developed, thermotolerance decays at a faster rate than that normally observed in cells of nonhemopoietic origin. Thermotolerance induction and maintenance correlates with reduced levels of expression of various Mr 70,000 heat shock proteins (HSP-70) mRNAs after heat shock. We ...

To characterize heat-shock proteins (HSPs) of the 70-kDa family in the crayfish medial giant axon (MGA), we analyzed axoplasmic proteins separately from proteins of the glial sheath. Several different molecular weight isoforms of constitutive HSP 70s that were detected on immunoblots were approximately 1-3% of the total protein in the axoplasm of MGAs. To investigate inducible HSPs, MGAs were h...
