TNF and mastitis: Although leukocyte recruitment can also increase the local free radical production to unbalanced levels, thus compromising the oxidative status of milk, as has been previously described in cows, goats, and sheep [44,45,46], it is not clear whether the anti-inflammatory content of human milk in mastitis affected women, provides an extra protection against these changes [30]; these authors proposed that the increased contents of selected components in womens’ mastitis milk (e.g., TNFa or IL-1RA) might help protect the nursing infant from clinical illness due to feeding on mastitis milk [30].
