Abstract
Polyunsaturated fatty acids (PUFAs) are important immune modulating elements. Prostaglandins and leukotrienes, which play an important role in the immune response, are derived from PUFAs. Furthermore, PUFAs can alter immune cell function via various mechanisms, including the activation of transcription factors. The development of the immune system occurs mostly perinatally, and since most PUFAs are acquired from the diet, the maternal diet may influence fetal and neonatal PUFA status. To investigate the effect of w-3 and w-6 PUFAs during gestation and/ or lactation on the immune response later in life, pregnant and/or lactating BALB/c mice were fed diets varying in w- 3/w-6 PUFA ratios. After weaning, pups were transferred to a Western-style diet, and the possible immuno-modulatory effects of maternal diet were investigated using the ovalbumine (OVA)-induced model for experimental allergic asthma. Significant differences in the acute allergic skin response were observed between different diet groups and between different feeding periods, indicating a long lasting effect of the maternal diet on the immune response of the offspring. A higher level of w-3 PUFAs in the maternal diet leads to a significantly diminished acute allergic skin response, suggesting an important role for maternal w-3 PUFAs in the development of allergy.
