The Role of High Mobility Group Box 1 (HMGB1) in Neurodegeneration: A Systematic Review
View through CrossRef
Background:
High mobility group box 1 (HMGB1) protein is a damage-associated molecular
pattern (DAMP) that plays an important role in the repair and regeneration of tissue injury. It
also acts as a pro-inflammatory cytokine through the activation of toll-like receptor 4 (TLR4) and
receptor for advanced glycation end products (RAGE), to elicit the neuroinflammatory response.
HMGB1 may aggravate several cellular responses, which may lead to pathological inflammation
and cellular death. Thus, there have been a considerable amount of research into the pathological
role of HMGB1 in diseases. However, whether the mechanism of action of HMGB1 is similar in all
neurodegenerative disease pathology remains to be determined.
Objective:
Therefore, this systematic review aimed to critically evaluate and elucidate the role of
HMGB1 in the pathology of neurodegeneration based on the available literature.
Methods:
A comprehensive literature search was performed on four databases; EMBASE, PubMed,
Scopus, and CINAHL Plus.
Results:
A total of 85 articles were selected for critical appraisal, after subjecting to the inclusion
and exclusion criteria in this study. The selected articles revealed that HMGB1 levels were found
elevated in most neurodegeneration except in Huntington’s disease and Spinocerebellar ataxia,
where the levels were found decreased. This review also showcased that HMGB1 may act on distinctive
pathways to elicit its pathological response leading to the various neurodegeneration processes/
diseases.
Conclusion:
While there have been promising findings in HMGB1 intervention research, further
studies may still be required before any HMGB1 intervention may be recommended as a therapeutic
target for neurodegenerative diseases.
