Summary: HMGB1, a non-histone protein, is released by stressed, dying, or dead cells into the extracellular matrix, potentially impacting cancer cells' ability to evade immune surveillance. Through recognition as a ligand, TLR4 mediates the induction of TGF-beta by HMGB1, leading to the expression of the immunosuppressive protein galectin-9 in cancer cells.

Summary: The study found that HMGB1 is an independent risk factor for carotid plaque vulnerability in diabetic patients, with higher levels of HMGB1 and inflammatory cytokines in ICAS patients compared to WICAS patients. Among ICAS patients, those with unstable plaque had even higher levels of these cytokines. HMGB1 and osteoprotegerin were independently associated with unstable plaque in ICAS patients.

Summary: Careful monitoring of mild/moderate COVID-19 patients is crucial due to the rapid progression of complications. This study identified HMGB1 and HO-1 as potential biomarkers for COVID-19 management, based on their serum concentrations at hospital admission. The increase in HO-1 may provide protection against oxidative stress and inflammation, while the level of HMGB1 reflects the activity of the innate immune system.

Summary: HMGB1 is a multifunctional nuclear protein that plays a critical role in the inflammatory signaling pathway. Elevated levels of HMGB1 in COVID-19 patients are associated with disease severity and complications. Targeting the HMGB1 pathway may be beneficial in reducing the severity of the disease.

Summary: The study found that HMGB1 expression is upregulated in liver allografts during acute rejection, leading to increased inflammatory cell infiltration and DC maturation, ultimately promoting T cell proliferation and differentiation. Inhibition of HMGB1 with glycyrrhizic acid during liver preservation was shown to reduce inflammation, hepatocyte damage, and prolong allograft survival time, suggesting a potential therapeutic target to prevent acute rejection in liver transplantation.

Summary: The levels of HMGB1 in plasma, platelets, and plasma-derived microvesicles were significantly higher in women with unexplained recurrent pregnancy loss (uRPL) compared to control women. Expression of HMGB1 in the endometrium was also higher in women with uRPL. These findings suggest the involvement of HMGB1 in uRPL.

Summary: HMGB1 is a cytokine that serves as a marker of inflammation and has multiple functions depending on its subcellular location. CSF HMGB1 may play a role in the pathological mechanisms underlying complications associated with CNS diseases. Measuring the level of HMGB1 in the CSF can help predict disease progression and contribute to pathological alterations in distant areas.

Summary: Knocking out HMGB1 in tumor cells suppresses tumor growth in vivo, mediated by CD8 T cells, and leads to accelerated infiltration of CD8 T cells, macrophages, and dendritic cells in the tumor tissues. Manipulation of tumor-derived HMGB1 could improve the clinical outcomes of cancer immunotherapies.

Summary: High-mobility group box 1 (HMGB1) is a protein that regulates transcription in the cell nucleus and activates the innate immune system. It can cross the blood-brain barrier (BBB) and affect neuroimmune signaling in the brain and periphery. In this study, the ability of radioactively labeled HMGB1 to cross the BBB was examined. The results showed that HMGB1 could bidirectionally cross the BBB and its transport rates were enhanced by inflammation. This finding suggests that HMGB1 levels have an impact on neuroimmune signaling in various conditions.

Summary: Proteomic analysis and glucose uptake studies in Gdi1 knockout mice reveal significant changes in astrocyte-resident glycolytic enzymes and increased glucose uptake, leading to cognitive impairment. A selective impairment in working memory was observed in mice with Gdi1 deletion restricted to astrocytes, which was rescued by inhibiting glycolysis. These findings suggest a new astrocyte-based mechanism in neurodevelopmental disorders and potential therapeutic opportunities targeting aerobic glycolysis.

Summary: This study aimed to assess whether dysglycemia diagnosed during COVID-19 pneumonia could become a potential public health problem after the infection is resolved. The research found that COVID-19-associated dysglycemia is unlikely to be a lasting public health problem, thereby cautioning against alarmist claims on the risk of diabetes after COVID-19 pneumonia.

Summary: This study aims to provide a comprehensive characterization of stemness in pancreatic ductal adenocarcinoma (PDAC) cell lines. The expression of cancer stem cell (CSC) markers in 17 cell lines was evaluated. The study found that a higher degree of stemness was associated with in vivo tumorigenicity, but not with in vitro growth kinetics, clonogenicity, and chemo-resistance. In addition, the degree of stemness was associated with the expression of specific genes and the secretion of specific proteins.

Summary: This study analyzed the immune profiles of 18 hospitalized children with SARS-CoV-2 infection and found that different severity levels of children cases showed different immune characteristics. Infants with severe symptoms exhibited high inflammatory response and extreme antibody response, while mild cases had lower levels of inflammation and antibodies. Overall, the immune response in children is directly correlated with the clinical severity.

Summary: This study reveals the development of acute inflammation in rats after instillation of heat-inactivated bacteria in the ductal compartment of the pancreas. Although the inflammation subsided after three weeks, a subset of rats exhibited accumulation of T cells around the affected islets, resembling the insulitis seen in human T1D. These findings highlight the interplay between innate and acquired immunity in the pathogenesis of T1D.
