Hypothesis
Granulysin acts as a double-edged sword at the maternal-fetal interface, serving both protective and potentially harmful roles during pregnancy.
Conclusion
Granulysin can protect both the mother and fetus from pathogens while also potentially causing pregnancy disorders if NK cells become hyperactivated.
Supporting Evidence
- Granulysin is highly expressed in human NK cells and has significant cytolytic activity against various pathogens.
- During early pregnancy, granulysin expression increases, suggesting a protective role at the maternal-fetal interface.
- Excessive activation of NK cells can lead to the apoptosis of trophoblast cells, potentially causing pregnancy complications.
Takeaway
Granulysin is a special protein that helps keep both mothers and babies safe from germs, but if it gets too active, it can also cause problems during pregnancy.
Limitations
The exact mechanisms of granulysin's actions and its physiological roles are not fully understood.
