Resumen
La autofagia, un proceso celular, puede conducir a la supervivencia celular o la muerte celular programada (PCD). Esta revisión se centra en los mecanismos de muerte celular autofágica (ACD) en las plantas y su papel en las respuestas al estrés.
Área de la Ciencia:
- Biología vegetal
- Biología celular
- Biología molecular
Sus antecedentes:
- La autofagia es un proceso catabólico conservado crucial para la homeostasis celular.
- Se degradan los componentes citoplasmáticos a través de la fusión de los autofagosomas con los lisosomas.
- Aunque es conocida por su adaptación al estrés, la autofagia también media la muerte celular programada (PCD).
Objetivo del estudio:
- Para revisar las funciones fisiológicas de la autofagia.
- Hacer hincapié en los mecanismos recientemente identificados de la muerte celular autofágica (DAC) en las plantas.
- Explorar el papel del ACD en las respuestas al estrés y el desarrollo de las plantas.
Principales métodos:
- Revisión de la literatura sobre la investigación de la autofagia.
- Centrarse en los estudios que investigan la muerte celular autofágica (DAC) en las plantas.
- Análisis de los datos moleculares y fisiológicos relacionados con el DCA.
Principales resultados:
- La autofagia juega un doble papel, promoviendo la supervivencia celular o la DPC.
- Se están aclarando cada vez más los mecanismos específicos de ACD en las plantas.
- El ACD está implicado en el desarrollo de las plantas y las respuestas al estrés ambiental.
Conclusiones:
- El papel de la autofagia se extiende más allá de la supervivencia para incluir la muerte celular programada.
- Comprender el ACD en las plantas ofrece información sobre la resiliencia y el desarrollo de las plantas.
- Se necesitan más investigaciones para desentrañar completamente las complejidades del ACD en las plantas.

01:18Autophagic Cell Death
3.5K
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.

01:30Overview of Cell Death
7.7K
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...

01:27Autophagy
4.6K
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

01:17Phagocytosis of Apoptotic Cells
4.0K
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.

11.9K
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...

01:36Delivery Pathways to the Lysosome
7.0K
Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...
