Insights

Researchers explored programmed cell death in liver injury after ischemia/reperfusion. Targeting pathways like apoptosis and mitogen-activated protein kinases (MAPKs) shows promise for improving liver viability, though optimal treatments are still needed.

Area of Science:

  • Hepatology
  • Cellular Biology
  • Transplantation Medicine

Background:

  • Hepatic ischemia/reperfusion (I/R) injury is a significant complication in liver surgery and transplantation.
  • Programmed cell death plays a critical role in the pathogenesis of liver I/R injury.
  • Understanding intracellular mechanisms is key to developing protective strategies.

Purpose of the Study:

  • To review recent advances in intracellular mechanisms of programmed cell death in hepatic I/R injury.
  • To identify potential molecular targets for therapeutic intervention.
  • To assess the efficacy of agents targeting these pathways.

Main Methods:

  • Literature review of studies on programmed cell death in hepatic I/R injury.
  • Analysis of molecular pathways including death receptors, mitochondrial apoptosis, p53, MAPKs, and proteases.
  • Evaluation of preclinical and clinical data on therapeutic agents.

Main Results:

  • Several molecular targets within programmed cell death pathways have been identified.
  • Agents targeting these pathways have demonstrated potential in inhibiting injury and improving survival.
  • Specific pathways like mitochondrial apoptosis and MAPKs are highlighted as crucial.

Conclusions:

  • Targeting intracellular programmed cell death mechanisms offers a promising therapeutic avenue for hepatic I/R injury.
  • Pharmaceutical agents show potential for enhancing liver viability during surgical procedures.
  • Further research is needed to develop an optimal treatment strategy.

The Extrinsic Apoptotic Pathway01:17

The 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...
The Intrinsic Apoptotic Pathway01:31

The 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...
Cellular Injury IV: Necrosis01:16

Cellular Injury IV: Necrosis

Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...
Cellular Injury V: Apoptosis and Autophagy01:22

Cellular Injury V: Apoptosis and Autophagy

Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
Cellular Injury IlI: Cellular Death01:11

Cellular Injury IlI: Cellular Death

Cell death is the irreversible loss of cellular structure and function, representing the final stage of severe injury. It plays a key role in both normal physiology and disease.Types of Cell DeathThe two main types are necrosis and apoptosis, though others like necroptosis and pyroptosis also exist.Necrosis:Necrosis is an unregulated form of cell death caused by severe injury such as trauma, toxins, or ischemia. It is characterized by cell swelling, membrane loss, rupture, and leakage of...
Phagocytosis of Apoptotic Cells01:17

Phagocytosis 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.
