Hypothesis
Some low levels of LT-B could stimulate non-detectable levels of specific antibody but result in immune priming.
Conclusion
The study found that LT-B derived from transgenic maize is immunogenic at nanogram levels when orally administered to mice.
Supporting Evidence
- Mice fed 0.02 μg LT-B demonstrated immune priming in 62.5% of the animals.
- Mice that were fed ≤ 0.002 μg LT-B showed no increase in specific antibody.
- High specific antibody concentrations were observed in groups fed high doses of LT-B maize.
Takeaway
This study shows that even tiny amounts of a protein from genetically modified corn can make mice's immune systems react.
Methodology
Mice were fed varying doses of transgenic maize expressing LT-B, and their immune responses were measured through serum and fecal samples.
Potential Biases
Potential variability in LT-B content in maize pellets could affect results.
Limitations
The study was conducted on mice, and results may not directly translate to humans.
Participant Demographics
4- to 6-week-old female BALB/c mice.
