(American Society for Microbiology) Scientists now report that Treg cells, a type of regulatory lymphocyte, may be protecting babies in the womb from getting infected with the HIV virus when the mother is infected. The research, from the Emory Vaccine Center, is presented at ASM Microbe, the American Society for Microbiology's annual meeting, held from June 7-11 in Atlanta, Ga.
