Which type of cells are particularly hindered in their function due to chronic stress? 

The correct answer is 'Natural Killer cells'

Key Points

• Natural Killer cells:
  • Natural Killer (NK) cells are a type of lymphocyte and a component of the innate immune system.
  • They play a crucial role in the body's defense against tumors and virally infected cells by inducing apoptosis (cell death).
  • Chronic stress has been shown to impair the function of NK cells, reducing their ability to respond to infections and malignancies effectively.
  • This impairment is partly due to the release of stress hormones such as cortisol, which can suppress the immune system's response.

Additional Information

• Erythrocytes:
  • Erythrocytes, or red blood cells, are responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide to be exhaled.
  • While chronic stress can indirectly affect erythrocytes by impacting overall health, they are not primarily hindered in their function by stress.
• Hepatocytes:
  • Hepatocytes are the main functional cells of the liver and are involved in metabolism, detoxification, and protein synthesis.
  • Chronic stress can affect liver function, but hepatocytes are not the primary cells hindered in their function due to stress.
• Platelets:
  • Platelets are small blood cells that help with clotting and wound healing.
  • Stress can influence platelet activity and increase the risk of clotting disorders, but they are not the main cells affected by chronic stress.
