Summary
Endoplasmic reticulum (ER) homeostasis is vital for delaying inflammation. ER-phagy, a cellular process, clears damaged ER and pathogens, curbing inflammatory responses and diseases.
Area of Science:
- Cellular Biology
- Immunology
- Molecular Biology
Background:
- The endoplasmic reticulum (ER) synthesizes, modifies, and folds proteins.
- ER dysfunction accelerates inflammatory responses and related diseases.
- Maintaining ER homeostasis is crucial for controlling inflammation.
Purpose of the Study:
- To review the role of ER-phagy in inflammation-related diseases.
- To highlight ER-phagy's mechanisms and receptors.
- To emphasize ER-phagy's therapeutic potential.
Main Methods:
- Literature review of ER-phagy research.
- Analysis of ER-phagy's role in immune signaling.
- Summary of ER-phagy's involvement in various diseases.
Main Results:
- ER-phagy acts as a cellular hub for immune and stress signals.
- It curbs NF-κB and NLRP3 inflammasome activation.
- ER-phagy clears pathogens and damaged ER fragments, maintaining immune homeostasis.
Conclusions:
- ER-phagy is a key regulator of inflammatory responses.
- It plays a significant role in various inflammation-related diseases.
- Targeting ER-phagy may offer therapeutic strategies for inflammatory conditions.

01:27Autophagy
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,...

01:36Delivery Pathways to the Lysosome
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...

01:22Cellular 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...
01:37The 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...
01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
