		Consequently, the heat shock proteins are also referred to as stress proteins and their upregulation is sometimes described more generally as part of the stress response.
		Heat shock proteins are molecular (One who accompanies and supervises a young woman or gatherings of young people) chaperones for protein molecules.

	Heat shock proteins: basics (Site not responding. Last check: 2007-11-05)
		Heat shock proteins (HSPs), also called stress proteins, are a group of proteins that are present in all cells in all life forms.
		Heat shock proteins are also believed to play a role in the presentation of pieces of proteins (or peptides) on the cell surface to help the immune system recognize diseased cells.
		Heat shock proteins trigger immune response through activities that occur both inside the cell (intracellular) and outside the cell (extracellular).

	Heat shock protein 27 is associated with freedom from graft vasculopathy after human cardiac transplantation.
		Heat shock protein 27 is associated with freedom from graft vasculopathy after human cardiac transplantation.
		To identify proteins that may act as protectors from CAV, a global proteomic approach was used comparing cardiac biopsies from 12 patients taken within the first 2 weeks after transplant and those taken after 9 years from the same patient.
		A particular protein spot was found in 4/6 biopsies from patients without CAV, but absent from 5/6 biopsies from those with CAV (P=0.24); however, quantitative analysis of spot intensity showed a significant difference (0.061+/-0.05 versus 0.003+/-0.01, P=0.04).

	Heat-shock protein - Open Encyclopedia (Site not responding. Last check: 2007-11-05)
		Heat-shock proteins (otherwise known as HSPs or stress proteins) are created when cells are exposed to elevated temperatures, or to other kinds of environmental stress, such as ethanol, ultraviolet light, trace metals, or oxygen deprivation.
		These activities are part of a cell's own repair system, called the "cellular stress response" or the "heat-shock response." The function of heat-shock proteins is similar in virtually all living organisms, from bacteria to humans.
		Heat-shock proteins are of potential interest to cancer researchers, based on research that has shown that animals may respond to cancer "vaccinations." Tumor cells were "attenuated" (or weakened) and injected in small quantities into a rodent, causing the rodent to become immune to future full-fledged tumor-cell injections.

	Heat Shock Antigen Cancer Vaccine
		ITL's heat shock antigen vaccine (HSAV) is an investigational personalized vaccine designed to treat the immune systems of people with cancer while minimizing side effects.
		The HSAV is made from individual patients' tumors and heat shock proteins produced by the patients' own white blood cells.
		Using a proprietary process, heat shock proteins from the white blood cells are purified and combined with purified antigens from the tumor.

	Polymorphism and intracellular self/not-self discrimination
		Thus, polymorphism of intracellular proteins should be of adaptive value serving to amplify and individualise the immune response to intracellular pathogens.
		A viral protein (A) can be considered in the same way as a mutant oncogene, so that host proteins B, C and D would be recruited into the antigenic repertoire of the infected cell.
		Furthermore, the recruitment of only one host protein should suffice to trigger an antiviral response in that host, while, because of polymorphism, the same protein might not be recruited in a subsequent host (which might present peptides from another polymorphic protein).

	heat capacity on Encyclopedia.com
		or thermal capacity, ratio of the change in heat energy of a unit mass of a substance to the change in temperature of the substance; like its melting point or boiling point, the heat capacity is a characteristic of a substance.
		The measurement of heat and heat capacity is called calorimetry.
		In the metric system, heat capacity is often expressed in units of calories per gram per degree Celsius (cal/g-°C); in the English system, British thermal units per pound per degree Fahrenheit (Btu/lb-°F) are often used.
