A liter of mice milk goes for around 23,000 USD Making it the most expensive milk in the world (as far as data is concerned)
According to the researchers’ studies, certain gut-dwelling bacterial species are directly eliminated by the complementary components of mouse breast milk, improving the health of the young mice. Because of this alteration in the gut microbiota, the young mice are protected from several infectious risks and are considerably less prone to contract Citrobacter rodentium infections. It is believed that complement components normally function in conjunction with antibodies, but this remodeling action operates independently of them.
These complement components, which showed comparable efficacy in targeting particular bacteria, were also found to be present in human breast milk, as the researchers confirmed in further in vitro investigations.
When considered collectively, these results provide insight into the processes by which breast milk protects against specific bacterial illnesses.
The research was released online in the journal Cell on January 18.
According to study senior author Fengyi Wan, PhD, a professor in the Bloomberg School’s Department of Biochemistry and Molecular Biology, “these findings reveal a critical role for breast milk complement proteins in shaping offspring’s gut microbe compositions and protecting against bacterial infection in the gut in early life.” “This constitutes a significant advancement in our comprehension of the protective mechanisms of breast milk.”
