Autophagic Cell Death01:18

Autophagic Cell Death

4.5K
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.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

Overview of Cell Death

9.8K
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...

Autophagy01:27

Autophagy

5.8K
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,...

Cancer Cell Migration through Invadopodia

3.3K
Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

7.1K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

6.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Summary

Autophagy modulates immunogenic cell death (ICD) by influencing damage-associated molecular patterns (DAMPs). Its role is context-dependent, impacting antitumor immunity and offering therapeutic strategies for hematological malignancies.

Area of Science:

  • Immunology
  • Cell Biology
  • Oncology

Background:

  • Immunogenic cell death (ICD) triggers T-cell responses via damage-associated molecular patterns (DAMPs).
  • Autophagy, a cellular degradation process, significantly influences antitumor immunity and the tumor microenvironment (TME).

Purpose of the Study:

  • To summarize how autophagy impacts ICD-associated DAMPs.
  • To explore autophagy's dual role in promoting or limiting ICD in various cancer models.
  • To discuss the translational potential of modulating autophagy in cancer therapy.

Main Methods:

  • Review of preclinical models examining autophagy's effect on ICD.
  • Analysis of autophagy's impact on DAMPs, endoplasmic reticulum stress, and MHC presentation.
  • Focus on hematological malignancies, including multiple myeloma.

Main Results:

  • Autophagy can promote ICD by sustaining ER stress and secretory pathways.
  • Autophagy can limit ICD by degrading DAMPs and MHC molecules, with outcomes dependent on context.
  • The autophagy-related protein GABARAP is implicated in bortezomib-induced ICD in multiple myeloma.

Conclusions:

  • The interplay between autophagy and ICD is complex and context-dependent.
  • Modulating autophagy offers potential therapeutic strategies, particularly in combination with ICD-inducing agents.
  • Further research is needed to safely harness the autophagy-ICD axis in clinical settings.
