Vγ1+ T and Vγ4+ T cell are two main subsets of γδ T cells during Cm respiratory tract infection. The types of γδ T cell subsets from lung tissues in naïve (a, b) and infected mice (c, d) were defined according to the expression of TCRVγ mRNA in lungs detected by RT-PCR. Shown are the representative data of two independent experiments with similar results presented as mean ± SD. ^∗p < 0.05, ^∗∗p < 0.01, and ^∗∗∗p < 0.001.
