Although heat shock proteins (HSPs) primarily play a pivotal role in the maintenance of cellular homeostasis while reducing extracellular as well as intracellular stresses, their role in immunologically relevant scenarios, including activation of innate immunity as danger signals, antitumor immunity, and autoimmune diseases, is now gaining much attention. The most prominent feature of HSPs is t...

Many small molecules can self-assemble by non-covalent interactions into fibrous networks and thereby induce gelation of organic liquids. However, no capability currently exists to predict whether a molecule in a given solvent will form a gel, a low-viscosity solution (sol), or an insoluble precipitate. Gelation has been recognized as a phenomenon that reflects a balance between solubility and ...

The protective effects of heat shock proteins (HSPs) during myocardial ischemia are now well documented, but little is known about the mechanisms of protection and the specificity of different HSPs. Because cytoskeletal injury plays a crucial role in the pathogenesis of irreversible ischemic damage, we tested whether overexpression of specific HSPs protects the integrity of microtubules during ...

Heat-shock proteins (HSPs) act as molecular chaperones binding endogenous antigenic peptides and transporting them to major histocompatibility complexes. HSPs chaperone a broad repertoire of endogenous peptides including tumor antigens. For the immunotherapy of tumors, a strategy using HSPs may be more advantageous than other procedures because the identification of each tumor-specific antigen ...

Many DNA base substitution models have been proposed to describe the evolution of short DNA sequences. Most of these models are special reversible time-continuous Markov chains on the DNA bases. A general reversible model for long genomic DNA sequences, which includes the previous models as special cases, is described in this paper. To estimate the model parameters from pairwise alignments, two...

The resistance of cancer cells to photothermal therapy is closely related to the overexpression of heat shock proteins (HSPs), which are abnormally upregulated when cells are under lethal stresses. Common strategies that use small molecule inhibitors against HSPs to enhance hyperthermia effect lack spatial and temporal control of drug release, leading to unavoidable systemic toxicity. Herein, a...

Cells that have been pre-exposed to thermal stress can acquire a transient resistance against the killing effect of a subsequent thermal stress. The cause for this phenomenon, called thermotolerance, seems to be an enhanced resistance of proteins against thermal denaturation and aggregation. This resistance can be expressed as an attenuation of damage formation (less initial damage) or as a bet...

Parasitoid wasps inject their eggs into host along with virulent factors to manipulate hosts physiology and immune system. Heat shock proteins (HSPs) are as molecular chaperones and stress proteins induced by heat, cold, anoxia and parasitism. There was no report about the roles of HSP in insect eggs against egg parasitoids. Here, we studied the expression profiles of several HSPs in silkworm e...

Heat shock proteins (HSPs) have been known for decades for their ability to protect cells under stressful conditions. In the 1980s a new role was ascribed for several HSPs given their ability to elicit specific immune responses in the setting of cancer and infectious disease. These immune responses have primarily been harnessed for the immunotherapy of cancer in the clinical setting. However, b...

Ambient temperature is one of the most important environmental factors affecting physiological mechanisms and biochemical reactions of living organisms. Thus the effect of ambient temperature on HSPs and IGF-I gene expression levels in the liver and muscle tissues of Sparus aurata were investigated in this research. The levels of HSPs, and IGF-I gene expression of the liver and muscle of Sparus...
