HSP70, or Heat Shock Protein 70, is a type of protein that our bodies produce when cells are exposed to stressful conditions, such as heat, cold, or toxins. The “70” in HSP70 refers to its molecular weight.
Think of HSP70 as a kind of cellular bodyguard or maintenance worker. When a cell is under stress, its proteins can become damaged or misfolded, which can disrupt their function and potentially harm the cell. HSP70 helps by binding to these damaged proteins and assisting them to regain their proper shape, much like a handyman might fix a bent piece of machinery.
In this way, HSP70 plays a crucial role in protecting our cells from stress and maintaining their proper function. It’s particularly important in the brain, where it helps to protect neurons from damage.
