What happens after a blood meal? A transcriptome analysis of the main tissues involved in egg production in Rhodnius prolixus, an insect vector of Chagas disease

The blood-sucking hemipteran Rhodnius prolixus is a vector of Chagas disease, one of the most neglected tropical diseases affecting several million people, mostly in Latin America. The blood meal is an event with a high epidemiological impact since adult mated females feed several times, with each meal resulting in a bout of egg laying, and thereby the production of hundreds of offspring. By means of RNA-Sequencing (RNA-Seq) we have examined how a blood meal influences mRNA expression in the central nervous system (CNS), fat body and ovaries in order to promote egg production, focusing on tissue-specific responses under controlled nutritional conditions. We illustrate the cross talk between reproduction and a) lipids, proteins and trehalose metabolism, b) neuropeptide and neurohormonal signaling, and c) the immune system. Overall, our molecular evaluation confirms and supports previous studies and provides an invaluable molecular resource for future investigations on different tissues involved in successful reproductive events. These analyses serve as a starting point for new investigations, increasing the chances of developing novel strategies for vector population control by translational research, with less impact on the environment and more specificity for a particular organism.

“…A number of neuropeptides genes detected in the current study are very similar to those identified in other in silico studies that have investigated related crustacean or insect species. Confirmation of neuropeptide genes in a diverse range of species is important since several arthropod neuropeptides have an unknown function, while others have a function that has only been partially confirmed or appear to have ambiguous roles27282930. A similar recent in silico analysis approach in M. rosenbergii central nervous system yielded 21 neuropeptide transcripts (with some having multiple isoforms) that encode up to 102 mature peptides6.…”

“…In contrast, much less information is available about bursicon function in crustaceans. However, it is known that injection of recombinant bursicon-β into female P. monodon broodstock causes an increase in vitellogenin gene expression and stimulated ovarian development28.…”

“…Still, it is important to note that in spite of the known function of some members in the CHH superfamily, their identity and functionality is vastly uncharacterised13. Lastly, there are numerous neuropeptides that have previously been demonstrated to have other functions (for example, cardio-activity, osmoregulation, pigmentation, stress response) but then later were assigned novel roles in reproduction and/or sexual development27282930. These findings highlight that while our understanding of the molecular mechanisms of neuropeptides involved in crustacean reproduction processes is quite advanced, it is yet still far from being complete.…”

The Australian redclaw crayfish (Cherax quadricarinatus) has recently received attention as an emerging candidate for sustainable aquaculture production in Australia and worldwide. More importantly, C. quadricarinatus serves as a good model organism for the commercially important group of decapod crustaceans as it is distributed worldwide, easy to maintain in the laboratory and its reproductive cycle has been well documented. In order to better understand the key reproduction and development regulating mechanisms in decapod crustaceans, the molecular toolkit available for model organisms such as C. quadricarinatus must be expanded. However, there has been no study undertaken to establish the C. quadricarinatus neuropeptidome. Here we report a comprehensive study of the neuropeptide genes expressed in the eyestalk in the Australian crayfish C. quadricarinatus. We characterised 53 putative neuropeptide-encoding transcripts based on key features of neuropeptides as characterised in other species. Of those, 14 neuropeptides implicated in reproduction regulation were chosen for assessment of their tissue distribution using RT-PCR. Further insights are discussed in relation to current knowledge of neuropeptides in other species and potential follow up studies. Overall, the resulting data lays the foundation for future gene-based neuroendocrinology studies in C. quadricarinatus.

Recently, a novel function of bursicon was reported in the stimulation of Vg expression in the black tiger shrimp, Penaeus monodon [87]. In R. prolixus, we find higher expression of the bursicon receptor in OVs with respect to the CNS and FB (Fig 8B and S2 Table), suggesting a novel role for this hormone in reproductive physiology in an insect.…”
