Necrosis01:16

Necrosis

4.8K
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...

Area of Science:

  • Biomedical Engineering
  • Cancer Therapeutics
  • Cell Death Mechanisms

Background:

  • Ferroptosis is an iron-dependent regulated cell death (RCD) characterized by peroxidative membrane damage.
  • Targeting ferroptosis is a promising cancer therapy strategy, with nanomaterial-induced ferroptosis gaining significant attention.
  • Current limitations include insufficient immunogenic cell death induction for clinical applications.

Purpose of the Study:

  • To review nanomaterial-based ferroptosis inducers.
  • To explore the mechanisms of ionizing radiation (IR)-induced ferroptosis.
  • To assess the combined potential of nanomaterials and IR for enhanced ferroptosis induction in cancer therapy.

Main Methods:

  • Literature review of nanomaterial-based ferroptosis inducers.
  • Summary of mechanisms underlying IR-induced ferroptosis.
  • Feasibility assessment of combining nanomaterials with IR for synergistic ferroptosis.

Main Results:

  • Nanomaterials offer diverse strategies for inducing ferroptosis.
  • Ionizing radiation (IR) has been shown to further induce ferroptosis.
  • The combination of nanomaterials and IR presents a potential strategy to overcome current ferroptosis limitations.

Conclusions:

  • Combining nanomaterials with IR is a feasible strategy to enhance ferroptosis induction.
  • This combined approach may improve immunogenic cell death and clinical applicability.
  • Further research is warranted to explore the synergistic effects of nanomaterials and IR for cancer therapy.
