TSLP and infection: In the case of TSLP levels of expression, the serotypes a (p < 0.0001), b (p < 0.0001), and c (p < 0.0001), induced an overexpression of this molecule compared to the non-infected condition at 2 h of infection; similarly, at 24 h of infection, serotype a (p < 0.0001), b (p = 0.0327), and c (p < 0.0001) were able to induce statistically significant higher relative expression than the uninfected condition.
