Core Tip

Core Tip: Over 240 million people all round the world are chronically infected with hepatitis B virus, resulting in > 1 million deaths per year. Previous studies have suggested that the costimulatory molecule 4-1BB plays a pivotal role in regulating immunity during chronic viral infection. However, up to now, there is no study about 4-1BB expression in chronic hepatitis B to clarify the role of 4-1BB in the process of chronic hepatitis B clearly. Here, we report our comprehensive study on the expression levels of soluble 4-1BB in plasma and 4-1BB mRNA in peripheral blood mononuclear cells to further explain it.
