Comparative proteomic analysis of the saliva of the Rhodnius prolixus, Triatoma lecticularia and Panstrongylus herreri triatomines reveals a high interespecific functional biodiversity

Effect of the saliva from different triatomine species on the biology and immunity of TLR-4 ligand and Trypanosoma cruzi-stimulated dendritic cells

“…The observed events are quite relevant because IL-12 and TNF-α are cytokines related with the induction of inflammation and mounting of a Th1-type response profile, hostile environment for vectors and pathogens transmitted by them [31]. Rhodnius prolixus did not show strong inhibition in cytokine production but it is already known that this species has its saliva constituted of nitrophorins as the most abundant molecules [32] and so far no activity involving DCs was attributed to these molecules. It is noteworthy that the saliva of R. prolixus induced 16% of apoptosis and this could explain some of the R. prolixus inhibition only in dilution 1:30.…”

Study of the Salivary Glands in Triatominae (Hemiptera, Reduviidae, Triatominae): Their Color and Application to the Chagas Disease Vector Evolution

“…4 The salivary glands of triatomines perform a fundamental role during hematophagy because their saliva is rich in proteins and anticoagulant and hemolytic enzymes. 5,6 These structures have been studied anatomically, 7 histologically, 7 biochemically, 5 molecularly, 8 and cytogenetically 9 based on a few triatomines of the genera Triatoma, Rhodnius, and Panstrongylus.…”

“…17 This study demonstrates that the species of the tribes Triatomini and Cavernicolini do not have this heme protein in the composition of their salivary glands. In the few studies that characterize the salivary glands of other genera of the tribe Triatomini, the substances isolated were triabin and pallidipin in M. pallidipennis 18 ; triafestins, triplatin, and trialysin in T. infestans 19,20 ; procalin in T. protracta 20 ; dipetalodipin in D. maxima 20 ; and lipocalin in T. lectularia 8 and P. herreri. 8 Therefore, this study highlights the presence of nitrophorin proteins as a synapomorphy of the tribe Rhodniini and suggests that this tribe has derived more recently when compared with the tribes Triatomini and Cavernicolini, which contributes to understanding the evolutionary history of this important vector group.…”

Panstrongylus herreri and its ability to develop under fluctuating environmental conditions

“…However, it is important to mention that the taxonomic status of this species has been controversial. Some authors have cited this species as P. herreri (1)(2)(3)(4)(5) , while others have referred to this species as P. lignarius (6)(7)(8)(9)(10) . Therefore, there is a clear lack of consensus regarding this matter, which reinforces the significance of the question raised by the comments on our study.Another interesting aspect posed by the comments refers to the total number of species of triatomines identified so far (152 species).…”
