As we know that human breast milk is the prime source of the nutrition for newborn babies before they are able to eat and digest other foods. The first milk, colostrum, which is enriched with immunoglobulin IgA, helps to protect the newborn until its own immune system is functioning properly, and creates a mild laxative effect, expelling meconium and helping to prevent the build-up of bilirubin, a prime factor which finally causes Jaundice.
Now researcher at University of North Carolina Center for Infectious Diseases and the University of North Carolina Center for AIDS Research have been found an unknown ingredient in the breast milk which is able to kill HIV (Human Immunodeficiency Virus) particles and virus-infected cells that finally causes AIDS. This unknown mysterious ingredient is also able to block HIV transmission in mice with a human immune system.
In order to prove the fact, Angela Wahl, the chief researcher and her team generated mice with human bone marrow, liver and thymus tissues and given them a oral dose of HIV virus and breast milk with HIV virus respectively and observed the result. She found that all the mice has become infected if they were given an oral dose of the virus and surprisingly she found that the virus was not transmitted if the rodents were fed breast milk containing HIV.
Now they are trying to identify that mysterious ingredient residing in breast milk which inhibit the HIV virus and if they get succeed, it can be used probably to prevent the other forms of HIV transmission, such as sexual transmission.
