[Liver sinusoidal endothelial cells regulate adaptive immune tolerance in the liver]
1Department of Infectious Diseases, Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology, Wuhan 430022, China.
Summary
Liver sinusoidal endothelial cells (LSECs) normally survey the liver but can induce immune tolerance, promoting persistent viral infections and tumor metastasis. This review details how LSECs suppress CD4+ and CD8+ T cell responses.
Area of Science:
- Immunology
- Hepatology
- Cell Biology
Background:
- Liver sinusoidal endothelial cells (LSECs) are key nonparenchymal cells in the liver.
- LSECs express scavenger and pattern recognition receptors for immunological surveillance.
- Under certain conditions, LSECs induce immune tolerance, contributing to disease.
Purpose of the Study:
- To review the mechanisms by which LSECs induce immune tolerance.
- To understand LSEC-mediated suppression of CD4+ and CD8+ T cells in the liver.
Main Methods:
- Literature review of immunological and cellular mechanisms.
- Analysis of LSEC function in physiological and pathological states.
- Focus on T cell tolerance induction by LSECs.
Main Results:
- LSECs employ diverse mechanisms to establish immune tolerance in the liver.
- This tolerance can lead to persistent viral infections.
- LSEC-mediated tolerance also facilitates tumor metastasis by suppressing anti-tumor T cell immunity.
Conclusions:
- LSECs play a critical dual role in liver immunity: surveillance and tolerance induction.
- Understanding LSEC tolerance mechanisms is crucial for treating liver diseases.
- Targeting LSEC-mediated immune suppression may offer therapeutic strategies for viral infections and cancer.

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.

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.

The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

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...
