Immune Surveillance by NK Cells and Phagocytes01:25

Immune Surveillance by NK Cells and Phagocytes

9.5K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

Overview of DNA Repair

35.2K
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

5.6K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized...

Cells of the Innate Immune Response01:28

Cells of the Innate Immune Response

10.4K
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

DNA Damage can Stall the Cell Cycle02:36

DNA Damage can Stall the Cell Cycle

10.4K
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

  • Molecular Biology
  • Genetics

Background:

  • Macrophage homeostasis is vital for immune system function.
  • DNA damage response (DDR) pathways are critical for maintaining genomic stability.
  • Dysregulation of DDR is implicated in various inflammatory diseases.

Purpose of the Study:

  • To investigate the role of DNA damage response (DDR) components in macrophage homeostasis.
  • To elucidate the impact of DDR defects on macrophage inflammatory responses.

Main Methods:

  • Utilized genetic models to study DDR component function in macrophages.
  • Analyzed macrophage populations and inflammatory markers.
  • Assessed cellular responses to DNA damage.

Main Results:

  • A defect in a specific DDR component was found to alter macrophage homeostasis.
  • Impaired DDR led to dysregulated inflammatory responses in macrophages.
  • The study identified a novel link between DDR and macrophage immune functions.

Conclusions:

  • DNA damage response pathways are essential regulators of macrophage homeostasis.
  • Defects in DDR can lead to aberrant inflammatory responses, contributing to disease pathogenesis.
  • Targeting DDR pathways may offer therapeutic strategies for inflammatory conditions.
