Summary: Research found that CH25H inhibits virus replication by producing 25HC, playing an important role in the replication of SVV. 25HC is involved in the entire life cycle of SVV, especially in repressing its adsorption process.

Summary: Marek's disease virus (MDV) causes a deadly lymphoproliferative disease in chickens, resulting in huge economic losses in the poultry industry. It has been suggested that MDV suppresses the induction of type I interferons and thus escapes immune control. The genes CH25H and CYP27A1, which encode enzymes that have antiviral activities, may be useful in controlling MDV replication and spread.

Summary: Avian reovirus (ARV) poses a significant threat to the poultry industry by causing viral arthritis/tenosynovitis and viral enteritis in domestic fowl. Previous research has highlighted the importance of cellular cholesterol in lipid rafts for ARV replication. This study reveals that the expression of chicken CH25H (chCH25H) is upregulated in ARV-infected cells and has a significant antiviral effect against ARV infection.

Summary: There is cross talk between HBV and the host through the CH25H-HBx axis. The expression of CH25H is increased in HBV-infected patients and is associated with low HBV replication. CH25H and its mutants interact with HBx protein and inhibit the nuclear translocation of HBx. 25HC promotes HBV infection but not replication.

Summary: Classical swine fever virus (CSFV) utilizes cellular lipids and manipulates host lipid metabolism to ensure its replication. In this study, we screened the anti-CSFV activity of 12 compounds targeting lipid metabolism pathways. 25-hydroxycholesterol (25HC) exhibited potent anti-CSFV activity by inhibiting virus entry into cells.

Summary: Viral infections pose significant threats to human health, with cholesterol 25-hydroxylase (CH25H) playing a crucial role in modulating immune responses and influencing viral infections. Viruses can antagonize CH25H to enhance replication and pathogenesis, but targeting CH25H or its downstream signaling pathways may offer potential strategies to control viral infections and enhance antiviral immune responses.

Summary: CH25H has been shown to have an antiviral effect in Senecavirus A (SVA) infection, with its product 25-hydroxycholesterol (25HC) inhibiting viral attachment and replication. Even the CH25H mutant lacking hydroxylase activity can still restrict SVA infection by selectively interacting and degrading SVA 3A protein.

Summary: This article reviews the function of Cholesterol-25-hydroxylase (CH25H) in intestinal immunity and its role in regulating inflammatory response, signal transduction, cell migration, and lipid metabolism. The aim is to provide evidence for the discovery of early diagnostic and treatment targets for inflammatory bowel disease (IBD).

Summary: PDCoV infection upregulates CH25H expression, with overexpression inhibiting viral replication while silencing promotes infection. Treatment with 25HC or a mutant CH25H lacking hydroxylase activity both inhibit PDCoV infection to varying extents.

Summary: Efficient antiviral drug discovery is a pressing issue in global public health. Recent studies have shown that 25-hydroxycholesterol (25HC) has broad-spectrum antiviral activity with high efficiency and low toxicity. It restricts viral internalization and disturbs the maturity of viral proteins through multiple mechanisms. Understanding the role of 25HC in innate immunity may contribute to the development of urgently needed broad-spectrum antiviral drugs.

Summary: Angiotensin II (AngII) and 25-hydroxycholesterol (25-HC) both play detrimental roles in cardiovascular health. AngII stimulation was found to significantly upregulate Ch25h mRNA levels in vascular smooth muscle cells (VSMCs), with the upregulation being dependent on type 1 angiotensin II receptor and G(q/11) activity. The production of 25-HC in VSMCs was observed to peak 4 hours after AngII stimulation. These findings provide insights into the connection between AngII stimulus and 25-HC production, potentially leading to new understandings of vascular impairments.

Summary: This study found that the serum levels of 25HC and 27HC were elevated in COVID-19 patients, while the levels of 7KC were lower compared to healthy controls. However, there was no significant correlation between 25HC levels and disease severity markers. Dexamethasone effectively suppressed CH25H expression, mitigating the increased effects of COVID-19 on 25HC serum levels.

Summary: Astrocytes are important for cholesterol synthesis and metabolism, and spinal cord injury can disrupt this process leading to neuroinflammation. Thrombin activation plays a role in increasing astrocyte CH25H expression, leading to the production of 25-HC. Inhibiting thrombin activation can reduce inflammation and improve motor function in spinal cord injury.
