Resumen
Los fagocitos manejan la carga metabólica de engullir células muertas mediante el procesamiento de los contenidos de la célula ingerida. Esta revisión explora cómo el metabolismo celular y la digestión impactan en este proceso crucial de engulfment.
Área de la Ciencia:
- Biología celular Biología celular.
- Inmunología Inmunología.
- El metabolismo es el metabolismo.
Sus antecedentes:
- Miles de millones de células sufren apoptosis (muerte celular programada) todos los días.
- Los fagocitos envuelven estas células apoptóticas para el aclaramiento.
- La envuelta duplica efectivamente el contenido celular de un fagocito, lo que plantea desafíos metabólicos.
Objetivo del estudio:
- Revisar el metabolismo celular de los fagocitos durante el aclaramiento celular apoptótico.
- Para discutir la digestión de las células apoptóticas ingeridas.
- Para examinar el impacto de estos procesos metabólicos en la función de engulfment.
Principales métodos:
- Revisión de la literatura de los estudios sobre el metabolismo de los fagocitos.
- Análisis de los procesos celulares involucrados en la digestión celular apoptótica.
- Síntesis de los hallazgos sobre la relación entre el metabolismo y el engulfment.
Principales resultados:
- Los fagocitos poseen vías metabólicas especializadas para manejar el material ingerido.
- La digestión eficiente de las células apoptóticas es fundamental para mantener la homeostasis de los fagocitos.
- El estado metabólico influye en la capacidad del fagocito para una mayor engulfment.
Conclusiones:
- El metabolismo de los fagocitos es fundamental para manejar la carga de la depuración celular apoptótica.

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.

01:18Autophagic Cell Death
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

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.
01:30Overview of Cell Death
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...

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...
