Insights

Hepatocellular carcinoma (HCC) involves immune suppression via cells like regulatory T cells. Removing these suppressor cells can boost anti-tumor immunity in HCC patients.

Area of Science:

  • Immunology
  • Oncology

Background:

  • Hepatocellular carcinoma (HCC) is known to trigger immune suppression in patients.
  • Various cellular mechanisms contribute to this immune evasion.

Purpose of the Study:

  • To summarize the latest research on immune suppressor cells in HCC.
  • To provide a comprehensive overview of cellular immune suppression in HCC.

Main Methods:

  • Literature search for studies on immune suppressor cells in HCC.
  • Compilation and summary of findings from in vitro and in vivo studies.

Main Results:

  • Identified multiple suppressor cell types including regulatory T cells, dendritic cells, neutrophils, monocytes, and myeloid-derived suppressor cells.
  • Demonstrated that abrogating these suppressor cells enhances anti-tumor immune responses.

Conclusions:

  • Immune suppressor cells play a critical role in HCC progression.
  • Targeting these suppressor cells represents a potential therapeutic strategy for HCC.

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

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...
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...
