Hypothesis

Can Lactococcus lactis NCC 2287 alleviate food allergic manifestations in sensitized mice?

Conclusion

Lactococcus lactis NCC 2287 shows potential as a probiotic strain for managing allergic symptoms in sensitized mice.

Supporting Evidence

  • Lactococcus lactis NCC 2287 reduced allergic scores in sensitized mice during the management phase.
  • The strain did not show preventive effects when administered before sensitization.
  • IL-13 levels were significantly decreased in the ileum of treated mice.

Takeaway

This study found that a specific probiotic can help reduce allergy symptoms in mice that are already allergic, but it doesn't help prevent allergies from developing in the first place.

Methodology

BALB/c mice were sensitized with ovalbumin and cholera toxin, then treated with Lactococcus lactis NCC 2287 during the management phase after sensitization.

Potential Biases

Potential bias in the selection of the probiotic strain and the specific model used.

Limitations

The study only tested one strain of probiotic and focused on a specific model of food allergy.

Participant Demographics

Female BALB/c mice, six weeks old.
