Stress proteins in CNS inflammation.

Area of Science:

• Cellular Biology
• Neuroscience
• Immunology

Background:

• Heat shock proteins (HSPs) are essential molecular chaperones involved in protein folding, transport, and degradation.
• Dysfunctional HSPs are implicated in the accumulation of protein aggregates seen in neurodegenerative diseases.
• Emerging evidence reveals HSPs have roles beyond protein homeostasis, including regulating apoptosis and inflammation.

Purpose of the Study:

• To review the traditional and novel functions of HSPs.
• To highlight the relevance of HSPs in neurodegeneration and neuroinflammation.
• To explore HSPs as potential therapeutic targets for central nervous system (CNS) disorders.

Main Methods:

• Literature review of established and recent research on HSP functions.
• Focus on studies investigating HSPs in the context of neurodegenerative and neuroinflammatory conditions.
• Analysis of HSPs' roles as extracellular mediators and their receptor interactions.

Main Results:

• HSPs are vital for cellular metabolism and protein quality control.
• Stress-inducible HSPs modulate apoptosis, antigen presentation, and inflammatory signaling.
• Extracellular HSPs act as inflammatory mediators, interacting with specific receptors.

Conclusions:

• HSP functions extend beyond protein folding to encompass critical roles in inflammation.
• Altered HSP function is a common factor in neurodegenerative diseases.
• HSPs represent promising therapeutic targets and entities for treating CNS disorders.
