[Stress proteins in medicine]

Area of Science:

• Molecular Biology
• Cellular Biology
• Biochemistry

Context:

• Stress proteins, also known as heat shock proteins (HSPs), constitute a fundamental cellular defense system.
• HSPs are vital for preventing protein aggregation and facilitating protein refolding following cellular stress.
• Their role extends to essential cellular processes including protein transport, signaling, and degradation.

Purpose:

• To review the multifaceted roles of stress proteins in cellular function and disease pathogenesis.
• To highlight the protective effects of stress proteins in various conditions like ischemia/reperfusion injury, diabetes, and neurodegenerative diseases.
• To explore the therapeutic potential of stress proteins in autoimmune diseases, cancer therapy, and longevity.

Summary:

• Stress proteins are critical for cellular homeostasis, protecting against damage from ischemia/reperfusion, diabetes, and neurodegenerative conditions.
• They play a role in the etiology of autoimmune diseases and are implicated in antigen presentation for anticancer therapies.
• HSPs contribute to longevity and may buffer silent mutations, potentially influencing 'civilizational diseases' like cancer and atherosclerosis.

Impact:

• Understanding stress protein function offers insights into disease mechanisms and provides a basis for novel therapeutic strategies.
• Pharmacological targeting of stress proteins presents a promising avenue for treating a wide spectrum of human diseases.
• This review consolidates current knowledge on stress proteins, guiding future research in molecular medicine and drug development.
