Maturation of the Intracellular Parasite and Antigenicity

Novartis Foundation Symposium, 1983
The protein antigens synthesized by the malarial parasite change as the parasite matures, with a number of proteins showing strict stage-specificity. A detailed correlation between the stage-specificity of protein synthesis and parasite structure has yet to be established, but a number of proteins synthesized in the cycle are lost selectively during ...

Calcium signaling in intracellular protist parasites

Current Opinion in Microbiology, 2021
Calcium ion (Ca2+) signaling is one of the most frequently employed mechanisms of signal transduction by eukaryotic cells, and starts with either Ca2+ release from intracellular stores or Ca2+ entry through the plasma membrane. In intracellular protist parasites Ca2+ signaling initiates a sequence of events that may facilitate their invasion of host ...

Arginine sensing in intracellular parasitism of Leishmania

Current Opinion in Microbiology, 2021
Protozoa of the genus Leishmania are intracellular parasites that cause human leishmaniasis, a disease spread mostly in the tropics and subtropics. Leishmania cycle between the midgut of female sand flies and phagolysosome of mammalian macrophages. During their life cycle they constantly encounter changing nutritional environments.

Intracellular Parasite Invasion Strategies

Science, 2004
Intracellular parasites use various strategies to invade cells and to subvert cellular signaling pathways and, thus, to gain a foothold against host defenses. Efficient cell entry, ability to exploit intracellular niches, and persistence make these parasites treacherous pathogens.

Chlamydiae and the biochemistry of intracellular parasitism

Trends in Microbiology, 1994
Despite the clinical and economic importance of chlamydial infections, many aspects of their basic biology, biochemistry and genetics have not been studied, and the metabolic relationships that exist between chlamydiae and their hosts are just beginning to be elucidated. While chlamydiae can biosynthesize some metabolic intermediates, they appear to be

Metal ion homeostasis and intracellular parasitism

Molecular Microbiology, 1998
Bacteria possess multiple mechanisms for the transport of metal ions. While many of these systems may have evolved in the first instance to resist the detrimental effects of toxic environmental heavy metals, they have since become adapted to a variety of important homeostatic functions.

[Intracellular parasitism and sarcocystosis].

Izvestiia Akademii nauk. Seriia biologicheskaia, 2001
The obligatory heterogenous tissue cyst-forming coccidia of the genus Sarcystosis are regarded as an excellent example of specific coexistence of two organisms, i.e., the host and parasite. These parasitic protozoans are known as causative agents of the chronic, often life-threatening disease, sarcocystosis, which still cannot be effectively controlled.

Intracellular parasitism of macrophages by Cryptococcus neoformans

Trends in Microbiology, 2001
Cryptococcus neoformans, an encapsulated fungal pathogen, causes meningoencephalitis in immunocompromised patients. Recent in vivo studies have demonstrated that C. neoformans is a facultative intracellular pathogen, as was previously suggested by in vitro studies. For survival in macrophages, C.

Leishmania species: models of intracellular parasitism

Journal of Cell Science, 1999
ABSTRACT Leishmania species are obligate intracellular parasites of cells of the macrophage-dendritic cell lineage. Indeed, the ability to survive and multiply within macrophages is a feature of a surprising number of infectious agents of major importance to public health, including Mycobacterium tuberculosis, Mycobacterium leprae ...

Nutrient acquisition by intracellular parasitic protists

Cell Host & Microbe
Parasitic protists belonging to the Apicomplexa and Trypanosomatidae are the cause of important diseases and life-long chronic infections in humans. Several of these parasites replicate within intracellular niches in their mammalian host, including specialized vacuoles, as well as endo-lysosomal compartments or the cytosol of infected cells.
