Insights

In chronic severe hepatitis B (CSHB), liver-infiltrating CD4(+) T cells, CD8(+) T cells, and NK cells are abundant and may drive disease progression. These immune cells show different frequencies in the liver compared to peripheral blood.

Area of Science:

  • Immunology
  • Hepatology
  • Cell Biology

Context:

  • Chronic severe hepatitis B (CSHB) is a significant global health concern.
  • Understanding the role of immune cells in liver pathogenesis is crucial for developing effective treatments.

Purpose:

  • To investigate the frequencies of immunologically competent cells (ICCs) in liver-infiltrating lymphocytes (LILs) and peripheral blood of CSHB patients.
  • To explore the potential role of these ICCs in the pathogenesis of CSHB.

Summary:

  • LILs from CSHB patients showed significantly lower frequencies of CD4(+) T cells and B cells but higher frequencies of CD8(+) T cells, NK cells, and NKT cells compared to peripheral blood.
  • CSHB patients exhibited higher frequencies of infiltrating CD3(+) and CD4(+) T cells in the liver compared to normal controls (NCs).
  • Ratios of liver-infiltrating CD4(+) T cells to peripheral blood CD4(+) T cells were significantly higher in CSHB patients.

Impact:

  • The findings suggest that abundant infiltrating immune cells, particularly CD4(+) T cells, CD8(+) T cells, and NK cells in the liver, may be key drivers of CSHB progression.
  • This research provides insights into the immunopathogenesis of CSHB, potentially guiding future therapeutic strategies targeting specific immune cell populations.

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
Liver Regeneration01:24

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...

Immune Response Against Viral Pathogens

The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
Cells of the Adaptive Immune Response01:23

Cells of the Adaptive Immune Response

The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
