Heat Shock Proteins

Meaning

Heat Shock Proteins, or HSPs, are a family of highly conserved proteins that function primarily as essential molecular chaperones, assisting in the proper folding, assembly, transport, and degradation of other proteins within the cell. These proteins are rapidly upregulated in response to various cellular stressors, including heat, oxidative stress, and infection, acting as a crucial, non-specific defense mechanism to maintain protein homeostasis and cellular viability. Their central role in cellular resilience and protein quality control is fundamental to modern longevity research.
