Nimrod B2 and eater homologs as functional markers of hemocyte phagocytosis. The role of nimrod B2 and eater silencing on in vivo phagocytosis was evaluated in Am. maculatum hemocytes (A). qPCR validation of bulk RNA expression profiles of nimrod B2 and eater in uninfected and R. parkeri-infected Am. maculatum hemocytes (B). dsRNA was injected into Am. maculatum female ticks to disrupt the expression of nimrod B2 and eater genes and confirmed by qPCR (C). The proportion of phagocytic hemocytes was compared with dsGFP-injected ticks (D). Additional validation of phagocyte depletion showing a significant reduction in nimrod B2 (E) and eater (F) transcript in CLD-injected ticks. Gene expression was normalized to Am. maculatum actin. Data were analyzed using unpaired t-tests in GraphPad Prism v8.4.1. *P < 0.05, ****P < 0.0001.
