First, we assessed early TFH differentiation at day 3 after infection, and interestingly, we found that hCre-transduced (GFP+) SMARTA cells with Rictor knocked out showed a similar frequency of Tim3loCXCR5+ TFH cells to empty vector-transduced (GFP+) and non-transduced (GFP−) SMARTA cells (Figure 3A). Here, RICTOR is linked to infection.
