Hypothesis
Does variation in the NOD2 gene influence T cell responses in patients with multiple sclerosis?
Conclusion
The study found that a specific NOD2 polymorphism influences T helper cell responses in patients with multiple sclerosis.
Supporting Evidence
- Seven of 29 patients with a specific NOD2 polymorphism showed increased T cell proliferation.
- Patients with the polymorphism had higher levels of IL-5 and IL-17 production.
- No associations were found between other NOD2 polymorphisms and T cell responses.
Takeaway
Some people with multiple sclerosis have a gene variation that makes their immune system react more strongly to a protein from myelin, which is important for nerve health.
Methodology
The study examined the effects of three NOD2 gene polymorphisms on T cell responses in blood samples from 29 patients with multiple sclerosis.
Potential Biases
The absence of a healthy control group limits the ability to generalize the findings.
Limitations
The study had a small sample size and lacked patients homozygous for the minor alleles of the polymorphisms examined.
Participant Demographics
29 patients with multiple sclerosis, including 20 women and 9 men, median age 34 years.
