Whereas there was a clear association between increases in Th1 cells and Tregs in the UGT, such a pattern was not as clear for the LGT, as the RT-PCR detection revealed only 6-fold increases in FoxP3 mRNA in the LGT as compared to nearly 40-fold increases in the UGT over the course of the infection. This evidence concerns the gene SLC35A2 and infection.
