Vγ6+ γδ T cells are critical for protection against infection by Escherichia coli in mice.

γδ T cells producing IL-17A (γδTh17 cells) are known to be involved in peritonitis induced by Escherichia coli infection in mice. In vivo treatment with Vγ6-specific mAb (1C10-1F7) significantly hampered resolution of E. coli infection. Thus, Vγ6+ γδTh17 cells mainly contributed to protection against E. coli infection.
