Figures
The images for Figs 4 to 7 are incorrectly switched. The image that appears as Fig 4 should be Fig 5, the image that appears as Fig 5 should be Fig 6, the image that appears as Fig 6 should be Fig 7 and the image that appears as Fig 7 should be Fig 4. The figure captions appear in the correct order. The authors have provided a corrected version of figures here.
The histology of BSFL is presented in longitudinal sections (A, B, C) and cross sections (D, E, F). H&E staining revealed the main structure of the fifth instar of BSFL (A, D). BSFL were stained with naïve mouse serum as a negative control (B, E). BSFL were stained by chromogenic IHC methods following injection of mice anti-BSFL CTSL serum (C, F). Positive signals were revealed in brown, while hematoxylin was used as a counterstain. H, head. (Bar = 500 μm).
Relative mRNA expression (2 -ΔΔct) levels of CTSL were detected using SRBR green assay and normalized to β-actin. The fold-change of CTSL expression was calculated for the 3rd, 4th, 5th, and 6th instars and compared with the 2nd instar. Bars represent mean ± S.E. (n = 3). Letters indicate significant differences (p < 0.05).
Relative mRNA expression (2 -ΔΔct) levels of CTSL were detected using SRBR green assay and normalized to β-actin in the 2nd (A), 3rd (B), 4th (C), 5th (D), and 6th (E) instars. The fold-change of CTSL expression was calculated at 1.5, 3, 6, 9, and 12 h post-stimulation with E. coli and compared with 0 h (negative control was non-treated BSFL). Bars represent mean ± S.E. (n = 3). Statistical significance is indicated with lowercase letters (p < 0.05).
Percentage of CTSL activity in the fifth instar under E. coli challenge compared to negative control (cysteine proteinase inhibitor E-64). Error bars represent mean ± S.E. (n = 5). Statistical significance is indicated with different lowercase letters (p < 0.05).
