The intricate link between cholesterol metabolism and host immune responses is well recognized, but the specific mechanisms by which cholesterol biosynthesis influences hepatitis B virus (HBV) replication remain unclear. In this study, we show that SREBP2, a key regulator of cholesterol metabolism, inhibits HBV replication by interacting directly with the HBx protein, thereby preventing its nuclear translocation. We also found that inhibiting the ER-to-Golgi transport of the SCAP-SREBP2 complex or blocking SREBP2 maturation significantly enhances HBV suppression.

Immunoprophylaxis is routinely recommended for infants born to mothers with hepatitis B virus (HBV) infection within the first 12-24 hours. Detection of hepatitis B surface antibody (HBsAb) resulting from hepatitis B immunoglobulin administered at birth may be perceived as a real vaccine response. This makes it difficult to detect HBV infection.

Hepatitis B virus (HBV) infection causes acute and chronic hepatitis, compensated and decompensated cirrhosis, and hepatocellular carcinoma worldwide. The actual status of HBV infection and its treatment in certain regions of Asian and African countries, including Ethiopia, has not been well-documented thus far. Antiviral therapy for HBV infection can prevent the progression of HBV-related liver diseases and decrease the HBV-related symptoms, such as abdominal symptoms, fatigue, systemic symptoms and others.

Chronic kidney disease (CKD) ultimately causes renal fibrosis and end-stage renal disease, thus seriously threatens human health. However, current medications for CKD and fibrosis are inefficient, which is often due to poor targeting capability to renal tubule. In this study, we discover that biomimetic high-density lipoprotein (bHDL) lipid nanoparticles possess excellent targeting ability to injured tubular epithelial cells by kidney injury molecule-1(KIM-1) mediated internalization.

Extracellular vesicles (EVs) are generated in all cells. Systemic administration of allogenic EVs derived from epithelial and mesenchymal cells has been shown to be safe, despite carrying an array of functional molecules, including thousands of proteins. To address whether epithelial cell-derived EVs can be modified to acquire the capacity to induce an immune response, we engineered 293T EVs to harbor the immunomodulatory molecules CD80, OX40L, and PD-L1.
