Overview of Cell Death01:30

Overview of Cell Death

7.7K
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...

Necrosis01:16

Necrosis

5.2K
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...

Autophagic Cell Death01:18

Autophagic Cell Death

3.3K
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...

Cellular Injury IV: Necrosis01:16

Cellular Injury IV: Necrosis

63
Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...

Cellular Injury I: Introduction01:00

Cellular Injury I: Introduction

68
Cellular injury occurs when a cell cannot maintain homeostasis or adapt to stressors such as hypoxia, toxins, or trauma. Depending on severity and duration, injury may be reversible, allowing recovery, or irreversible, leading to cell death.General Mechanisms of Cell InjuryAlthough causes vary, most cellular injuries arise from a few key mechanisms that disrupt essential functions and often amplify one another. Cell survival depends on the extent and balance of these disturbances.ATP depletion...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

6.2K
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

Summary

Graphene oxide (GO) shows promise for cancer hyperthermia therapy. Researchers found that increasing laser power, not exposure time, effectively raises temperature and induces necrosis, releasing cytokines.

Area of Science:

  • Biomedical Engineering
  • Nanotechnology
  • Cancer Therapy

Background:

  • Graphene oxide (GO) offers unique properties for near-infrared (NIR) hyperthermia in cancer treatment.
  • Understanding GO-cell interactions and optimal hyperthermia parameters is crucial for effective therapy.

Purpose of the Study:

  • To investigate the impact of laser irradiation parameters on GO-mediated hyperthermia.
  • To evaluate the type of cell damage induced by varying laser power and exposure time.

Main Methods:

  • Graphene oxide (GO) was used in cell cultures.
  • Laser irradiation parameters (power and exposure time) were systematically varied.
  • Temperature changes and cell death mechanisms (necrosis, apoptosis) were analyzed.

Main Results:

  • Cell culture temperature increased more significantly with laser power than with exposure time.
  • Higher laser power led to necrosis as the primary mode of cell death.
  • Increased necrosis correlated with elevated cytokine release into the cell culture medium.

Conclusions:

  • Laser power is a key parameter for controlling GO-based hyperthermia efficacy.
  • GO-induced hyperthermia can effectively induce necrosis and cytokine release, suggesting potential in cancer therapy.
  • Further research into GO-cell interactions and optimized treatment protocols is warranted.
