Abstract
Trypanosomatids are protozoan parasites that cause deadly infectious diseases. Despite the unique characteristics of their cAMP signaling pathways, little is known about the mechanisms driving signal specificity in these early divergent eukaryotes. From the activation of adenylate cyclases in response to environmental cues to the downstream regulation of gene expression, the signaling mechanisms triggering developmental transformations in trypanosomes are poorly understood. In this review we integrate previous and new evidence supporting the existence of membrane microdomains that assemble cAMP signaling proteins in different subcellular compartments of Trypanosoma cruzi, the etiologic agent of Chagas disease. We also discuss the main cellular processes regulated by cAMP compartments in this parasite. Advances in this field are crucial to identifying new targets for antiparasitic interventions.
期刊介绍：
Since its inception as Parasitology Today in 1985, Trends in Parasitology has evolved into a highly esteemed review journal of global significance, reflecting the importance of medical and veterinary parasites worldwide. The journal serves as a hub for communication among researchers across all disciplines of parasitology, encompassing endoparasites, ectoparasites, transmission vectors, and susceptible hosts.
Each monthly issue of Trends in Parasitology offers authoritative, cutting-edge, and yet accessible review articles, providing a balanced and comprehensive overview, along with opinion pieces offering personal and novel perspectives. Additionally, the journal publishes a variety of short articles designed to inform and stimulate thoughts in a lively and widely-accessible manner. These include Science & Society (discussing the interface between parasitology and the general public), Spotlight (highlighting recently published research articles), Forum (presenting single-point hypotheses), Parasite/Vector of the Month (featuring a modular display of the selected species), Letter (providing responses to recent articles in Trends in Parasitology), and Trendstalk (conducting interviews). Please note that the journal exclusively publishes literature reviews based on published data, with systematic reviews, meta-analysis, and unpublished primary research falling outside our scope.
