Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

2.5K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Regulated Protein Degradation02:58

Regulated Protein Degradation

8.1K
It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

The Proteasome

1.3K
Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

8.2K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

Area of Science:

  • Immunology
  • Molecular Biology
  • Oncology

Background:

  • The immune system defends against pathogens and tumors but can cause damage if overactive, necessitating immune checkpoints for balance.
  • Immune checkpoints regulate immune responses, but pathogens and tumors exploit them to evade immune surveillance.
  • Current immune checkpoint blockade (ICB) therapies show limited efficacy, highlighting the need for novel therapeutic strategies.

Purpose of the Study:

  • To review the role of ubiquitination and deubiquitination in anti-tumor immunity.
  • To explore the potential of targeting these pathways to enhance immunotherapy efficacy.
  • To discuss the therapeutic significance of combining ubiquitination/deubiquitination targeting with ICB.

Main Methods:

  • Literature review of recent findings on ubiquitination/deubiquitination in anti-tumor immunity.
  • Analysis of the interplay between ubiquitination pathways and immune checkpoints.
  • Discussion of therapeutic strategies for targeting these pathways in cancer immunotherapy.

Main Results:

  • Ubiquitination and deubiquitination are crucial regulators of innate and adaptive immunity.
  • These processes significantly influence the modulation of immune responses.
  • Targeting ubiquitination/deubiquitination pathways offers a promising strategy to augment anti-tumor immunity.

Conclusions:

  • Simultaneous targeting of immune checkpoints and ubiquitination/deubiquitination pathways holds potential for improving cancer immunotherapy.
  • Further research into these combined strategies could lead to more effective treatments for a broader patient population.
  • This approach may overcome limitations of current ICB therapies and enhance overall therapeutic efficacy.
