CD3−CD20− cells produce more TGF-β from 14 dpi on (mean ± standard error, 5.47 ± 1.65) and showed a significant increase in mean TGF-β expression during both the acute phase of infection (21 dpi, mean ± standard error, 10.99 ± 2.99, p = 0.03) and the chronic phase of infection at 135 dpi (mean ± standard error, 14.87 ± 2.89, p = 0.0007) and 160 dpi (mean ± standard error, 11.48 ± 2.77, p = 0.02) compared to baseline values (mean ± standard error, 0.91± 0.26). The gene discussed is TGFB1; the disease is infection.
