WSP challenge in mosquito cells. qRT-PCR analysis of AMPs and innate immune genes at 3h post-WSP challenge in 4a3A (A) and Aa23T (B). Increased expression dependent on WSP quantities up to 5μg/ml was detected in all genes tested. Relative expressions were calculated to pkWSP (WSP protein treated with proteinase K) challenged cells and represent the average of 4 biological repeats +/- SE. Statistical analysis where performed using a Wilcoxon rank sum test (*p<0.05, **p<0.01).
