Resumen

El control de calidad del retículo endoplasmático (ER) es vital para la salud celular. La desregulación de los procesos de ER contribuye a las enfermedades degenerativas de la retina, ofreciendo nuevos objetivos terapéuticos para la pérdida de la visión.

Área de la Ciencia:

Biología celular
Oftalmología
Biología molecular

Sus antecedentes:

El retículo endoplasmático (ER) es un orgánulo crítico para la síntesis de proteínas, el plegamiento y la maduración en las células eucariotas.
La modificación proteica adecuada dentro de la ER es esencial para la homeostasis celular, impactando el estrés oxidativo, la apoptosis y la senescencia.
El control de calidad del retículo endoplasmático (ERQC) abarca el estrés del retículo endoplasmático (ERS), la autofagia del retículo endoplasmático (ERPA) y la degradación asociada al retículo endoplasmático (ERAD) para mantener la homeostasis de las proteínas.

Objetivo del estudio:

Revisar los mecanismos de control de calidad del retículo endoplasmático (ERQC).
Resumir los mecanismos patológicos de las principales enfermedades degenerativas de la retina (RDD) a través de la lente de ERQC.
Proporcionar nuevos conocimientos sobre las posibles estrategias terapéuticas para el DDR basadas en ERQC.

Principales métodos:

Revisión de la literatura sobre los procesos del ERQC.
Análisis de los datos existentes sobre la patogénesis de la retinopatía diabética, el glaucoma, la degeneración macular relacionada con la edad y la miopía axial.
Conectar las vías ERQC con los mecanismos moleculares subyacentes a estas enfermedades oculares.

Principales resultados:

El ER juega un papel importante en la patogénesis de varias RDD, incluida la DR, el glaucoma, la DMAE y la miopía axial.
Las vías disfuncionales de ERQC están implicadas en la progresión de estas condiciones cegadoras.
La comprensión de los mecanismos ERQC ofrece una nueva perspectiva sobre los fundamentos moleculares de la RDD.

Conclusiones:

El ERQC es un actor central en el mantenimiento de la salud ocular y su disfunción contribuye a la RDD.
La orientación de las vías ERQC presenta una vía prometedora para el desarrollo de nuevos tratamientos para las enfermedades degenerativas de la retina.
La investigación adicional sobre los mecanismos de ERQC podría desbloquear nuevas estrategias terapéuticas para prevenir o revertir la pérdida de visión.

Protein Folding Quality Check in the RER

Protein Folding Quality Check in the RER

ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

Export of Misfolded Proteins out of the ER

Export of Misfolded Proteins out of the ER

After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...

Role of ER in the Secretory Pathway

Role of ER in the Secretory Pathway

Eukaryotic cells have a special pathway that enables communication between various intracellular membrane-bound compartments and also with the extracellular environment. This pathway is termed as the secretory pathway.
Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...

Smooth Endoplasmic Reticulum

Smooth Endoplasmic Reticulum

Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

The Unfolded Protein Response

The Unfolded Protein Response

The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...

The Endoplasmic Reticulum

The Endoplasmic Reticulum

The endoplasmic reticulum or ER makes up for more than half of the membranes in a cell and accounts for 10% of total cell volume. It is also the primary protein and lipid synthesis factory for most cell organelles, such as the Golgi apparatus, lysosomes, secretory vesicles, and the plasma membrane. Despite being the most extensive and functionally complex subcellular organelle, ER was the last to be discovered. After years of deliberation, Keith Porter and George Palade in the year 1954,...
