the utility of plasmodium berghei as a rodent model for anti-merozoite malaria vaccine assessment.rodent malaria species plasmodium yoelii and p. chabaudi have been widely used to validate vaccine approaches targeting blood-stage merozoite antigens. however, increasing data suggest the p. berghei rodent malaria may be able to circumvent vaccine-induced anti-merozoite responses. here we confirm a failure to protect against p. berghei, despite successful antibody induction against leading merozoite antigens using protein-in-adjuvant or viral vectored vaccine delivery. no subunit vaccine approa ...023609325
systematic tracking of altered haematopoiesis during sporozoite-mediated malaria development reveals multiple response points.haematopoiesis is the complex developmental process that maintains the turnover of all blood cell lineages. it critically depends on the correct functioning of rare, quiescent haematopoietic stem cells (hscs) and more numerous, hsc-derived, highly proliferative and differentiating haematopoietic progenitor cells (hpcs). infection is known to affect hscs, with severe and chronic inflammatory stimuli leading to stem cell pool depletion, while acute, non-lethal infections exert transient and even p ...027335321
transmission-blocking interventions eliminate malaria from laboratory populations.transmission-blocking interventions aim to reduce the prevalence of infection in endemic communities by targeting plasmodium within the insect host. although many studies have reported the successful reduction of infection in the mosquito vector, direct evidence that there is an onward reduction in infection in the vertebrate host is lacking. here we report the first experiments using a population, transmission-based study of plasmodium berghei in anopheles stephensi to assess the impact of a tr ...023652000
a tetracycline-repressible transactivator system to study essential genes in malaria parasites.a major obstacle in analyzing gene function in apicomplexan parasites is the absence of a practical regulatable expression system. here, we identified functional transcriptional activation domains within apicomplexan ap2 (apiap2) family transcription factors. these apiap2 transactivation domains were validated in blood-, liver-, and mosquito-stage parasites and used to create a robust conditional expression system for stage-specific, tetracycline-dependent gene regulation in toxoplasma gondii, p ...023245327
hiv nonnucleoside reverse transcriptase inhibitors and trimethoprim-sulfamethoxazole inhibit plasmodium liver stages.although nonnucleoside reverse transcriptase inhibitors (nnrtis) are usually part of first-line treatment regimens for human immunodeficiency virus (hiv), their activity on plasmodium liver stages remains unexplored. additionally, trimethoprim-sulfamethoxazole (tmp-smx), used for opportunistic infection prophylaxis in hiv-exposed infants and hiv-infected patients, reduces clinical episodes of malaria; however, tmp-smx effect on plasmodium liver stages requires further study.023125449
a plasmodium calcium-dependent protein kinase controls zygote development and transmission by translationally activating repressed mrnas.calcium-dependent protein kinases (cdpks) play key regulatory roles in the life cycle of the malaria parasite, but in many cases their precise molecular functions are unknown. using the rodent malaria parasite plasmodium berghei, we show that cdpk1, which is known to be essential in the asexual blood stage of the parasite, is expressed in all life stages and is indispensable during the sexual mosquito life-cycle stages. knockdown of cdpk1 in sexual stages resulted in developmentally arrested par ...022817984
long-term live imaging reveals cytosolic immune responses of host hepatocytes against plasmodium infection and parasite escape mechanisms.plasmodium parasites are transmitted by anopheles mosquitoes to the mammalian host and actively infect hepatocytes after passive transport in the bloodstream to the liver. in their target host hepatocyte, parasites reside within a parasitophorous vacuole (pv). in the present study it was shown that the parasitophorous vacuole membrane (pvm) can be targeted by autophagy marker proteins lc3, ubiquitin, and sqstm1/p62 as well as by lysosomes in a process resembling selective autophagy. the dynamics ...026208778
evaluation of antiplasmodial activity of extracts and constituents from ampelozizyphus amazonicus.ampelozizyphus amazonicus ducke, a plant that is widely used by the population of the amazonian region to prevent and treat malaria, was investigated in this work, which describes, for the first time, the antiplasmodial activity of its extracts and associates this activity with its isolated constituents.026664012
genome-wide functional analysis of plasmodium protein phosphatases reveals key regulators of parasite development and differentiation.reversible protein phosphorylation regulated by kinases and phosphatases controls many cellular processes. although essential functions for the malaria parasite kinome have been reported, the roles of most protein phosphatases (pps) during plasmodium development are unknown. we report a functional analysis of the plasmodium berghei protein phosphatome, which exhibits high conservation with the p. falciparum phosphatome and comprises 30 predicted pps with differential and distinct expression patt ...025011111
quantification of sporozoite invasion, migration, and development by microscopy and flow cytometry.there is an important role for in vitro assays to better understand the initial steps of malaria infection. in this section, we describe both microscopy-based and flow cytometry-based sporozoite invasion, migration and development assays with the rodent malaria parasites, plasmodium berghei and plasmodium yoelii, and the human malaria parasite, plasmodium falciparum.022990793
in vitro and in vivo antimalarial activity and cytotoxicity of extracts, fractions and a substance isolated from the amazonian plant tachia grandiflora (gentianaceae).tachia sp. are used as antimalarials in the amazon region and in vivo antimalarial activity of a tachia sp. has been previously reported. tachia grandiflora maguire and weaver is an amazonian antimalarial plant and herein its cytotoxicity and antimalarial activity were investigated. spectral analysis of the tetraoxygenated xanthone decussatin and the iridoid aglyone amplexine isolated, respectively, from the chloroform fractions of root methanol and leaf ethanol extracts was performed. in vitro ...023827996
