Cathepsin L2 was significantly more abundant in sym hemocytes (1.79-fold; ***two-tailed unequal variance t test, p value 0.0001; error bars represent standard error of the mean (S.E.)).were more abundant in sym hemocytes (Tables II and III). Although linked to other cellular pathways, cathepsins are proteases activate
