Background: High mobility group box 1 (HMGB1) protein is a damage-associated molecular pattern (DAMP) molecule 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.

High mobility group box-1 (HMGB-1), a typical damage-associated molecular pattern protein released from various cells, was first identified in 1973. It is usually stored in the nuclei of cells. Several modifications of HMGB-1 promote its translocation to the cytosol, and it is actively or passively released from cells. When outside of the cells, HMGB-1is crucial in inflammation. It exerts its biological functions via interaction with its receptors, including receptor for advanced glycation end products (RAGE) and Toll-like receptor 4(TLR4). A large number of studies showed a close link between inflammation and thrombosis. This review demonstrated the increased expression of HMGB-1 in thrombosis-related diseases, including coronary artery disease, stroke, peripheral arterial disease, disseminated intravascular coagulation, and venous thrombosis. Besides, it summarized the current understanding of the emerging link between HMGB-1 and thrombosis from three aspects: platelet, NETs, and coagulation and fibrinolysis factors. Finally, it explored the possible therapeutic strategies targeting HMGB-1 for treating thrombosis-related diseases.

High mobility group box-1 (HMGB1) mainly belongs to the non-histone DNA-binding protein. It has been studied as a nuclear protein that is present in eukaryotic cells. From the HMG family, HMGB1 protein has been focused particularly for its pivotal role in several pathologies. HMGB-1 is considered as an essential facilitator in diseases such as sepsis, collagen disease, atherosclerosis, cancers, arthritis, acute lung injury, epilepsy, myocardial infarction, and local and systemic inflammation. Modulation of HMGB1 levels in the human body provides a way in the management of these diseases. Various strategies, such as HMGB1-receptor antagonists, inhibitors of its signalling pathway, antibodies, RNA inhibitors, vagus nerve stimulation etc. have been used to inhibit expression, release or activity of HMGB1. This review encompasses the role of HMGB1 in various pathologies and discusses its therapeutic potential in these pathologies.

Gliomas represent 60% of primary intracranial brain tumors and 80% of all malignant types, with highest morbidity and mortality worldwide. Although glioma has been extensively studied, the molecular mechanisms underlying its pathology remain poorly understood. Clarification of the molecular mechanisms involved in their development and/or treatment resistance is highly required. High mobility group box 1 protein (HMGB1) is a nuclear protein that can also act as an extracellular trigger of inflammation, proliferation and migration, through receptor for advanced glycation end products and toll like receptors in a number of cancers including gliomas. It is known that excessive release of HMGB1 in cancer leads to unlimited replicative potential, ability to develop blood vessels (angiogenesis), evasion of programmed cell death (apoptosis), self-sufficiency in growth signals, insensitivity to inhibitors of growth, inflammation, tissue invasion and metastasis. In this review we explore the mechanisms by which HMGB1 regulates apoptosis and autophagy in glioma. We also looked at how HMGB1 mediates glioma regression and promotes angiogenesis as well as possible signaling pathways with an attempt to provide potential therapeutic targets for the treatment of glioma.

Alzheimer’s disease (AD) is a devastating neurodegenerative disorder and a leading cause of dementia, with accumulation of amyloid-beta (Aβ) and neurofibrillary tangles (NFTs) as defining pathological features. AD presents a serious global health concern with no cure to date, reflecting the complexity of its pathogenesis. Recent evidence indicates that neuroinflammation serves as the link between amyloid deposition, Tau pathology, and neurodegeneration. The high mobility group box 1 (HMGB1) protein, an initiator and activator of neuroinflammatory responses, has been involved in the pathogenesis of neurodegenerative diseases, including AD. HMGB1 is a typical damage-associated molecular pattern (DAMP) protein that exerts its biological activity mainly through binding to the receptor for advanced glycation end products (RAGE) and toll-like receptor 4 (TLR4). RAGE and TLR4 are key components of the innate immune system that both bind to HMGB1. Targeting of HMGB1, RAGE, and TLR4 in experimental AD models has demonstrated beneficial effects in halting AD progression by suppressing neuroinflammation, reducing Aβ load and production, improving spatial learning, and inhibiting microglial stimulation. Herein, we discuss the contribution of HMGB1 and its receptor signaling in neuroinflammation and AD pathogenesis, providing evidence of its beneficial effects upon therapeutic targeting.

<b><i>Background:</i></b> Allergic rhinitis (AR) is characterized by an inflammatory reaction. High mobility group box 1 (HMGB1) protein and interleukin (IL)-33 are damage-associated molecular pattern molecules and have many characteristics similar to pro-inflammatory cytokines. However, the role of IL-33 and HMGB1 in AR remains unclear. The aim of this study is to explore the role of HMGB1 and IL-33 in AR. <b><i>Methods:</i></b> Twenty patients with AR (AR group) and 10 normal controls (normal group) were enrolled in this study. HMGB1 and IL-33 expression were analyzed by immunohistochemistry in epithelial cells of the inferior turbinate mucosa samples. Then, the human nasal mucosa epithelial cells (HNECs) were cultured in vitro, and the house dust mite allergen (Derp1) was used to stimulate the cells. Quantitative real-time PCR and ELISA assay were performed to detect HMGB1 and IL-33 expression in HNECs. <b><i>Results:</i></b> The expression of HMGB1 and IL-33 in the nasal mucosa was higher in the AR group than in the normal group, with a statistically significant difference (<i>p</i> &#x3c; 0.05). In HNECs of AR, the expression of both HMGB1 and IL-33 in stimulated groups was higher than that in non-stimulated groups. The differences were statistically significant (<i>p</i> &#x3c; 0.05). In addition, they increased gradually with the prolonging time and the concentration of the added Derp1. <b><i>Conclusions:</i></b> The expression of HMGB1 and IL-33 were both increased in AR. HMGB1 and IL-33 may have a close relationship in AR.
