Summary
Autoimmune liver diseases involve chronic inflammation and cell death. Targeting apoptosis, a key cellular response, offers a novel therapeutic strategy for these conditions.
Area of Science:
- Immunology
- Hepatology
- Cell Biology
Background:
- Autoimmune liver diseases are chronic inflammatory conditions causing hepatocyte and cholangiocyte injury.
- Apoptosis, or programmed cell death, is a significant feature in various liver diseases, potentially initiating inflammatory cascades.
- Soluble forms of Major Histocompatibility Complex class I-related chains A and B (MIC A and B) are elevated in autoimmune and cholestatic liver diseases.
Purpose of the Study:
- To review the role of apoptosis in immune-mediated liver diseases.
- To highlight the clinical significance of apoptosis-initiated cellular and cytokine cascades.
- To discuss emerging therapeutic strategies targeting apoptotic cell death.
Main Methods:
- Literature review focusing on apoptosis in autoimmune liver diseases.
- Analysis of studies reporting MIC A and B levels in liver disease patients.
- Examination of the mechanisms of MIC A and B in cellular stress and immune recognition.
Main Results:
- Apoptosis is an early cellular response to liver and biliary injury, triggering critical inflammatory pathways.
- Elevated soluble MIC A and B indicate cellular stress and are associated with autoimmune and cholestatic liver diseases.
- MIC A and B facilitate natural killer cell recognition of stressed cells, promoting cell death.
Conclusions:
- Apoptosis plays a central role in the pathogenesis of immune-mediated liver diseases.
- MIC A and B serve as potential biomarkers for cellular stress in liver conditions.
- Developing strategies to suppress apoptotic cell death represents a promising therapeutic avenue for liver diseases.

01:30Apoptosis
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
01:17Phagocytosis of Apoptotic Cells
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.
Normal cells contain receptors that prevent them from being recognized by phagocytes.

01:24Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
01:17The Extrinsic Apoptotic Pathway
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
01:01Regulation 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...
