Immunohistochemical Expression Of Natural Killer Cell Activity With CD107A In Ectopic Endometrium Patients With Endometriosis Compared To Normal Endometrium
Immunohistochemical Expression of Natural Killer Cell Activity with CD107A in Ectopic Endometrium Patients with Endometriosis Compared to Normal Endometrium
Introduction
Endometriosis is a complex and multifactorial gynecological disorder characterized by the growth of endometrial tissue outside the uterus, leading to chronic inflammation, pain, and infertility. The pathogenesis of endometriosis involves various factors, including hormonal, genetic, and immune system dysregulation. Natural Killer (NK) cells, a type of immune cell, play a crucial role in the recognition and rejection of endometrial cells. However, the activity of NK cells in endometriosis patients is often impaired, contributing to the development and progression of the disease. CD107A, a marker of NK cell activity, has been identified as a potential indicator of NK cell function. This study aims to investigate the immunohistochemical expression of NK cell activity with CD107A in ectopic endometrium patients with endometriosis compared to normal endometrium.
Background
Endometriosis is a common gynecological disorder affecting approximately 10% of women of reproductive age. The exact cause of endometriosis is still unknown, but it is believed to involve a combination of genetic, hormonal, and environmental factors. Immune system dysregulation is thought to play a significant role in the development and progression of endometriosis. NK cells, a type of immune cell, are involved in the recognition and rejection of endometrial cells. However, the activity of NK cells in endometriosis patients is often impaired, leading to the growth and survival of endometrial cells outside the uterus.
Research Purposes
The primary objective of this study is to determine the difference in the expression of NK cell activity using CD107A between endometriosis patients and individuals with normal endometrium. This study aims to investigate the immunohistochemical expression of NK cell activity with CD107A in ectopic endometrium patients with endometriosis compared to normal endometrium.
Methodology
This study was conducted with an analytical design of cases in the Department of Obstetrics and Gynecology as well as anatomical pathology of the Faculty of Medicine, University of North Sumatra at the Adam Malik Hospital Medan, between May and July 2015. The case group consisted of paraffin ectopic endometrium tissue blocks from endometriosis sufferers, while the control group was taken from normal endometrial tissue. Assessment of the proportion of expression of NK cell activity was carried out using quantitative methods. Statistical analysis was carried out by Kappa test and Fisher Exact test with a confidence level of 95%, where the results with P <0.05 were considered significant.
Research Result
The total participants in this study consisted of 23 endometriosis sufferers and 23 individual controls. Most women in the endometriosis group were under 30 years old (43.5%), while the control group was mostly aged between 30-40 years (52.2%). All participants in the endometriosis group were nullipara, while among the controls, there were also multipara (39.2%). In terms of stage, most cases of endometriosis were at stage 4 (47.8%).
Statistical analysis using the Fisher Exact test showed the value of P <0.05, which indicates a significant difference in the proportional expression of CD107A between endometriosis tissue and normal endometrial tissue. This suggests a decrease in NK cell activity in groups of people with endometriosis.
Conclusion
This study shows a significant difference in the expression of NK cell activity between ectopic endometrial tissue in patients with endometriosis and normal endometrium. This discovery strengthens the importance of NK cells in endometriosis pathogenesis and can provide new insights in developing a more effective treatment strategy for this condition. By understanding the role of immune cells, especially NK cells, it is hoped that endometriosis handling can be increased in the future, so that the quality of life of patients can be better.
Implications
This study has several implications for the management of endometriosis. Firstly, it highlights the importance of NK cells in endometriosis pathogenesis, suggesting that therapeutic interventions targeting NK cell function may be beneficial. Secondly, it provides new insights into the mechanisms involved in endometriosis, which can inform the development of more effective treatment strategies. Finally, it emphasizes the need for further research into the role of immune cells in endometriosis, particularly NK cells.
Future Directions
Future studies should aim to investigate the mechanisms underlying the impaired NK cell activity in endometriosis patients. This may involve examining the expression of other immune-related genes and proteins, as well as investigating the effects of hormonal and environmental factors on NK cell function. Additionally, studies should aim to develop more effective treatment strategies targeting NK cell function, such as immunotherapy or hormone therapy.
Limitations
This study has several limitations. Firstly, the sample size was relatively small, which may limit the generalizability of the findings. Secondly, the study only examined the expression of CD107A, which may not be the only marker of NK cell activity. Finally, the study did not investigate the effects of hormonal and environmental factors on NK cell function.
Conclusion
In conclusion, this study demonstrates a significant difference in the expression of NK cell activity between ectopic endometrial tissue in patients with endometriosis and normal endometrium. This discovery highlights the importance of NK cells in endometriosis pathogenesis and provides new insights into the mechanisms involved in endometriosis. By understanding the role of immune cells, especially NK cells, it is hoped that endometriosis handling can be increased in the future, so that the quality of life of patients can be better.
Immunohistochemical Expression of Natural Killer Cell Activity with CD107A in Ectopic Endometrium Patients with Endometriosis Compared to Normal Endometrium: Q&A
Q: What is endometriosis and how does it affect women?
A: Endometriosis is a medical condition in which there is an abnormal endometrial tissue growth outside the uterine cavity. This tissue can be found in various places, such as ovaries, pelvic cavities, even intestines. Endometriosis can cause chronic pain, infertility, and other symptoms that can significantly impact a woman's quality of life.
Q: What is the role of natural killer (NK) cells in endometriosis?
A: NK cells are a type of immune cell that play a crucial role in the recognition and rejection of endometrial cells. However, the activity of NK cells in endometriosis patients is often impaired, contributing to the development and progression of the disease.
Q: What is CD107A and how is it related to NK cell activity?
A: CD107A is a marker of NK cell activity that has been identified as a potential indicator of NK cell function. It is a protein that is expressed on the surface of NK cells and is involved in the recognition and killing of target cells.
Q: What were the main findings of this study?
A: This study found a significant difference in the expression of NK cell activity between ectopic endometrial tissue in patients with endometriosis and normal endometrium. The study also found that the expression of CD107A was lower in endometriosis patients compared to controls.
Q: What are the implications of this study for the management of endometriosis?
A: This study highlights the importance of NK cells in endometriosis pathogenesis and suggests that therapeutic interventions targeting NK cell function may be beneficial.

Q: What are the limitations of this study?
A: This study has several limitations, including a relatively small sample size and the use of a single marker (CD107A) to assess NK cell activity. Future studies should aim to investigate the mechanisms underlying the impaired NK cell activity in endometriosis patients and develop more effective treatment strategies.
Q: What are the future directions for research on endometriosis and NK cell activity?
A: Future studies should aim to investigate the mechanisms underlying the impaired NK cell activity in endometriosis patients, including the effects of hormonal and environmental factors on NK cell function.
