Dr. Kurkchubasche studies conditions that affect the body's ability to fight infections and the growth of tumors, particularly in children. One of her key research areas involves Peutz-Jeghers syndrome, a genetic disorder that can lead to various types of tumors, including rare ovarian tumors. Additionally, she has researched Human Neutrophil Immunodeficiency Syndrome, which affects the immune system's ability to combat bacterial infections due to genetic mutations. Her studies contribute to a better understanding of how certain antibodies operate in the body and their role in preventing infections.
Key findings
In her 2016 study, Dr. Kurkchubasche reported an unusual Sertoli cell tumor in an 11-year-old girl with Peutz-Jeghers syndrome, emphasizing important insights into ovarian tumors linked to this condition.
In a 2000 study, it was found that a mutation in the Rac2 gene reduced the ability of a baby boy's neutrophils to produce a key molecule needed to fight bacteria by 96%, leading to severe immune deficiency.
Her 1994 research demonstrated that secretory IgA completely prevented E. coli bacteria from passing through the intestinal tissue in vitro, highlighting its importance in infection prevention.
Frequently asked questions

Unusual Sertoli Cell Tumor Associated With Sex Cord Tumor With Annular Tubules in Peutz-Jeghers Syndrome: Report of a Case and Review of the Literature on Ovarian Tumors in Peutz-Jeghers Syndrome.
2016
International journal of surgical pathology
Ravishankar S, Mangray S, Kurkchubasche A, Yakirevich E, Young RH
Plain English This study focuses on an 11-year-old girl with Peutz-Jeghers syndrome who had a specific type of ovarian tumor called a Sertoli cell tumor. The tumor was unusual because it had two distinct parts: one resembling normal Sertoli cells and another with a structure known as annular tubules. This research adds important information about ovarian tumors linked to Peutz-Jeghers syndrome, which is vital for understanding these rare cases.
Who this helps: This helps doctors and researchers better understand how to diagnose and treat ovarian tumors in patients with Peutz-Jeghers syndrome.
Human neutrophil immunodeficiency syndrome is associated with an inhibitory Rac2 mutation.
2000
Proceedings of the National Academy of Sciences of the United States of America
Ambruso DR, Knall C, Abell AN, Panepinto J, Kurkchubasche A +8 more
Plain English Researchers studied a 5-week-old baby boy who had severe infections and poor wound healing, which suggested problems with his immune system's neutrophils, a type of white blood cell. They found that his neutrophils didn't work properly due to a mutation in a gene called Rac2, which is crucial for the cells' ability to fight infections; this mutation led to significantly lower levels of Rac2 protein and reduced production of reactive oxygen species (which help kill bacteria). Understanding this mutation is important because it sheds light on the genetic causes of neutrophil disorders, which can guide better diagnosis and treatment.
Who this helps: This helps patients with immune deficiencies, their families, and healthcare providers.
Effect of secretory IgA on transepithelial passage of bacteria across the intact ileum in vitro.
1994
Journal of the American College of Surgeons
Albanese CT, Smith SD, Watkins S, Kurkchubasche A, Simmons RL +1 more
Plain English This study investigated how secretory IgA (sIgA) affects the movement of bacteria through the intestinal wall in rats. The researchers found that when sIgA was present, it completely stopped a type of bacteria called E. coli from passing through the intestinal tissue, while another antibody, IgG, reduced the amount but did not prevent it (showing a decrease in bacterial passage of about 5% compared to controls). This discovery is important because it shows that sIgA can effectively prevent harmful bacteria from entering the body, which could help reduce hospital infections.
Who this helps: This helps patients by potentially lowering their risk of infections related to bacteria.
