![]() They deliver antigens to the immune system’s antigen-presenting cells (APCs) through surface receptors. Heat shock proteins, mainly Hsp70 or Hsp90, alert the immune cells to antigens. Immune cells must be made aware of these antigens. These proteins act as antigens, which are foreign substances that initiate an immune response. When a cell is cancerous or infected by a pathogen, it creates proteins that are not normally found in the body. Heat-shock proteins are responsible for inhibiting both apoptotic and necrotic pathways. When cells are stressed, a common response is to undergo cell death by one of two pathways: necrosis or apoptosis. Hsp90 can stimulate the production of Hsp70 in the cell, which helps reduce the toxicity in the cell from the mutant and misfolded protein in Huntington’s disease. Ī drug named geldanamycin is known to regulate a heat shock protein, Hsp90. Heat shock proteins help prevent protein from forming aggregates by ensuring adequate folding. Having too many misfolded or unfolded proteins can lead to improper protein grouping/clumping and potentially result in different diseases like Huntington’s disease or Alzheimer’s. Proteins which do not fold appropriately can trigger an immune response and a host of other issues. Chaperone proteins regulate the folding of proteins, which is important for their specific roles. HSPs are also molecular chaperone proteins. Roles & Applications of Heat Shock Proteins 1) Act as Chaperones HSPs were discovered in relation to heat shock, but they play a role in different types of stress response, including cold exposure, wound healing, infections, and more. They can protect the cells from situations and extreme conditions that could otherwise be lethal. They are a family of proteins created by cells during stressful situations. Heat shock proteins (HSP’s) are found across all living species, from bacteria to humans. Read on to learn the roles of heat shock proteins in health and disease + factors that increase them. While they help protect the cells and balance the immune system, they also play roles in different chronic conditions. Heat shock proteins are created by cells under stressful conditions.
