Summary: Challenges still exist in assessing HBV-specific T cell immunity in chronic hepatitis B patients, including the need for large quantities of cells. In this study, a dataset of HBV-specific T cell receptor beta chains (TCR beta s) was established using public databases and samples from acute hepatitis B patients. Analysis of the potential HBV-specific TCR beta s from chronic hepatitis B patients showed that individuals with better therapy response may rely more on newly emerging TCR beta s. Furthermore, the characteristics of potential HBV-specific clusters were found to differ between chronic hepatitis B and hepatocellular carcinoma patients in a cross-sectional study. Our strategy provides a convenient method for assessing HBV-specific T cell immunity using a small blood sample.

Summary: This study investigated the potential mechanism and therapeutic potential of hepatitis B vaccine immunotherapy for occult hepatitis B virus infection (OBI) patients. The results showed that hepatitis B vaccine significantly increased the levels of hepatitis B surface antibodies in patients and had a significant impact on the number of peripheral blood B lymphocytes and CD8(+) T lymphocytes.

Summary: Chronic hepatitis B virus (HBV) infection poses a major threat to global public health, despite increasing vaccination rates. The outcome of HBV infection depends on the interaction between viral replication and host immune response. While innate immunity plays an initial role, long-term immunity is lacking due to HBV's ability to evade detection. Therefore, adaptive immunity involving T cells and B cells is crucial in controlling and clearing HBV infections. However, the persistence of HBV leads to immune tolerance and makes achieving a functional cure challenging.

Summary: High-density lipoproteins (HDLs) are heterogeneous lipoproteins that can modify their composition and functions depending on physiological or pathological conditions. Their main roles include cholesterol efflux, anti-inflammatory, and antioxidant functions, but may be compromised under pathological conditions. HDLs play a role in the immune system as anti-inflammatory molecules, but their composition changes when inflammation occurs.

Summary: The study demonstrated that the impact of hepatitis B virus on immune function varies in different ALT states. In patients with ALT >= double upper limit of normal, as the virus load increased, the total number of T lymphocytes and Th2 cell-related cytokines IL-4, IL-10 decreased, while Th1 cell-related cytokines IL-2, IFN-gamma increased.

Summary: Si-based biomaterials are widely used in bone regeneration, but their mechanisms of action are not fully understood. This study investigates the use of mesoporous silica (MS) as a model material and reveals that the supernatant of CD4+ T lymphocytes treated with MS extract promotes vascularized bone regeneration. The mechanism involves reducing the expression of regulatory factor X-1 (RFX-1) in CD4+ T lymphocytes, leading to overexpression of interleukin-17A (IL-17A) through increased histone H3 acetylation, decreased DNA methylation, and H3K9 trimethylation. In vivo experiments confirm that MS particles enhance bone regeneration and angiogenesis, accompanied by upregulated IL-17A in peripheral blood and increased proportion of Th17 cells. These findings highlight the importance of modulating the adaptive immune response of T lymphocytes for bone regeneration.

Summary: Acute pancreatitis is a complex inflammatory condition of the pancreas, mediated by various T cell subsets and B cells. The immune response, involving pro-inflammatory and anti-inflammatory cytokines, plays a crucial role in the pathogenesis of acute pancreatitis. Understanding the roles of immune cells, such as Treg, CD8(+) T cells, and B cells, may lead to the development of novel immunotherapies for better patient outcomes. However, more research is needed to determine the precise roles of these cells and their potential as therapeutic targets in acute pancreatitis.

Summary: Cancer immunotherapy efficacy can be improved by enhancing eosinophil infiltration through radiation, which also boosts the effectiveness of CD8(+) T cells and adoptive T cell therapy. Eosinophil mobilization may serve as a mechanistically relevant biomarker for predicting the effectiveness of pre-immunotherapy radiation and enhancing T cell-mediated immunotherapy against cancers.

Summary: Hepatitis B virus infection causes indirect damage to hepatocytes through the immune system. The exhaustion of virus-specific immune cells and immune suppression by virus antigens contribute to the chronicity of the infection. Functional cure can be achieved by restoring the specific immune function, providing a theoretical basis for complete cure of hepatitis B.

Summary: Bile acids (BAs), especially taurocholic acid (TCA), are significantly elevated in HBeAg-positive chronic hepatitis B (CHB) patients and inhibit the response to pegylated interferon-alpha (PegIFN alpha) therapy. These BAs reduce the number, proportion, and effector functions of CD3(+)CD8(+) T cells and natural killer (NK) cells in CHB patients.

Summary: Patients with chronic hepatitis B (CHB) are a long-term reservoir of hepatitis B virus (HBV). If not properly treated, these CHB patients may develop serious complications. Current antiviral drugs for CHB treatment cannot eradicate all forms of HBV and cannot stop the progression of complications for most patients. Therefore, there is an urgent need for the development of new therapies for CHB. Immune dysregulation may be responsible for HBV persistence and liver damage in CHB. Despite 30 years of immune therapies for CHB, an effective regimen of immune therapy is yet to be realized. This review discusses the pros and cons of different immune therapies for CHB patients in the past 30 years to provide insights for the development of an evidence-based, effective, and patient-friendly immune therapy regimen for CHB treatment.

Summary: Functional cure is considered achieved when chronic hepatitis B patients achieve HBsAg seroclearance after treatment. Clearing the virus is challenging due to the difficulty in clearing both cccDNA and integrated dslDNA. High levels of HBsAg in the serum lead to immune system failure, making it unable to produce an effective antiviral response. Only less than 1% of chronic hepatitis B patients are cured annually with antiviral treatment. Coinfection with other viruses such as HIV, HCV, and HDV makes it even more difficult to cure. However, it has been found that patients with coinfection have a higher probability of achieving HBsAg seroclearance, especially those with HBV/HIV coinfection with up to 36% 5-year seroclerance rate. This interesting phenomenon is related to the functional reconstruction of the immune system after antiretroviral therapy (ART).
