Neuropeptides in Rhipicephalus microplus and other hard ticks
Ticks and Tick-borne Diseases, 2022 The synganglion is the central nervous system of ticks and, as such, controls tick physiology. It does so through the production and release of signaling molecules, many of which are neuropeptides. These peptides can function as neurotransmitters, neuromodulators and/or neurohormones, although in most cases their functions remain to be established.

TOR as a Regulatory Target in Rhipicephalus microplus Embryogenesis [PDF]
Frontiers in Physiology, 2019 Embryogenesis is a metabolically intensive process carried out under tightly controlled conditions. The insulin signaling pathway regulates glucose homeostasis and is essential for reproduction in metazoan model species. Three key targets are part of this signaling pathway: protein kinase B (PKB, or AKT), glycogen synthase kinase 3 (GSK-3), and target ...

Acaricide resistance mechanisms in Rhipicephalus (Boophilus) microplus [PDF]
Revista Brasileira de Parasitologia Veterinária, 2012 Acaricide resistance has become widespread in countries where cattle ticks, Rhipicephalus (Boophilus) microplus, are a problem. Resistance arises through genetic changes in a cattle tick population that causes modifications to the target site, increased metabolism or sequestration of the acaricide, or reduced ability of the acaricide to penetrate ...

A Coxiella mutualist symbiont is essential to the development of Rhipicephalus microplus [PDF]
Scientific Reports, 2017 AbstractThe cattle tickRhipicephalus microplusis a hematophagous ectoparasite that causes important economic losses in livestock. Different species of ticks harbor a symbiont bacterium of the genusCoxiella. It was showed that aCoxiellaendosymbiont fromR.microplus(CERM) is a vertically transmitted mutualist symbiont, comprising 98% of the 16S rRNA ...
