Resumen
La ferroptosis, una vía única de muerte celular que involucra hierro y peroxidación lipídica, está cada vez más relacionada con enfermedades oculares. La comprensión de sus mecanismos ofrece nuevas dianas terapéuticas para afecciones como la DMAE y el glaucoma.
Área de la Ciencia:
- Oftalmología
- Biología Celular
- Bioquímica
Sus antecedentes:
- La ferroptosis es una forma distinta de muerte celular regulada por vías metabólicas, que implica peroxidación lipídica dependiente de hierro y especies reactivas de oxígeno (ROS).
- Difiere significativamente de la apoptosis, la necrosis y la autofagia, con características moleculares únicas.
- La investigación emergente destaca el papel de la ferroptosis en diversos procesos fisiológicos y patogénesis de enfermedades.
Objetivo del estudio:
- Revisar exhaustivamente los avances recientes en la investigación de la ferroptosis dentro de la oftalmología.
- Describir sistemáticamente los mecanismos moleculares y la significación fisiopatológica de la ferroptosis en enfermedades oftálmicas.
- Explorar el potencial de la ferroptosis como objetivo terapéutico para afecciones oculares.
Principales métodos:
- Revisión de literatura sobre ferroptosis en investigación oftalmológica.
- Análisis sistemático de mecanismos moleculares y roles fisiopatológicos.
- Discusión del potencial de traslación clínica y aplicaciones terapéuticas.
Principales resultados:
- La ferroptosis está implicada en la patogénesis de numerosas enfermedades oftalmológicas, incluidas la degeneración macular asociada a la edad (DMAE), la retinopatía diabética (RD), la lesión por isquemia-reperfusión retiniana (RIRI), la retinitis pigmentosa, la enfermedad del ojo seco, las cataratas y el glaucoma.
- La evidencia demuestra una fuerte asociación entre la ferroptosis y el desarrollo y progresión de estas afecciones oculares.
- Las vías moleculares que regulan la ferroptosis son cruciales para comprender los mecanismos de la enfermedad.
Conclusiones:
- La investigación sobre ferroptosis en oftalmología se está expandiendo rápidamente, revelando su papel crítico en las enfermedades oculares.
- La focalización de las vías de ferroptosis presenta prometedoras nuevas dianas moleculares y estrategias terapéuticas para afecciones oftálmicas.
- Se anticipa que una mayor exploración de los mecanismos de ferroptosis impulsará avances en la medicina de precisión para el cuidado de los ojos.

6.2K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

01:30Overview of Cell Death
9.3K
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...

13.9K
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...

01:18Autophagic Cell Death
4.3K
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.

01:17Phagocytosis of Apoptotic Cells
4.9K
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.

01:17The Extrinsic Apoptotic Pathway
8.0K
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...
