Abstract
Malaria predisposes to concomitant bacteremia, resulting in increased mortality risk. Previous studies indicated that malaria causes structural changes in the intestine, induces tolerogenic immune responses, inhibits neutrophil recruitment, suppresses innate synthesis of IFN-γ, dysregulates mast cells (MCs) and basophils, and induces Th2-type immune responses. These can reduce parasite control while increasing enteropathogenic dissemination. Moreover, there is growing evidence that Th2 immunity, while protecting the host from overwhelming inflammation, may also contribute to increased parasite transmission. This review explores the roles of the regulatory immune response in bacterial coinfections and parasite transmission in malaria.
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journal exclusively publishes literature reviews based on published data, with systematic reviews, meta-analysis, and unpublished primary research falling outside our scope.
