Toxoplasma gondii, Brazil

Emerging Infectious Diseases, 2007
Le virus H5N1), suggérant un effet de cohorte ou autre, n'a pas encore été publié, bien que des rapports anecdotiques d'enquêtes terminées indiquent un manque d'infection humaine généralisée par le virus (8). Les preuves actuelles indiquent que la grippe pandémique chez l'homme depuis 1918 a été limitée à 3 sous-types de virus de la grippe A : H1 (1918-

The impact of Foxp3+ regulatory T‐cells on CD8+ T‐cell dysfunction in tumour microenvironments and responses to immune checkpoint inhibitors

British Journal of Pharmacology, EarlyView.
Immune checkpoint inhibitors (ICIs) have been a breakthrough in cancer therapy, inducing durable remissions in responding patients. However, they are associated with variable outcomes, spanning from disease hyperprogression to complete responses with the onset of immune‐related adverse events.

Seroprevalence of Toxoplasma gondii antibodies and associated risk factors among children in Shandong and Jilin provinces, China

International Journal of Infectious Diseases, 2015
Objective: Infection by the protozoan parasite Toxoplasma gondii is generally prevalent in animals and humans worldwide. However, little is known about T. gondii infection among children in China.

Identification of Fis1 Interactors in Toxoplasma gondii Reveals a Novel Protein Required for Peripheral Distribution of the Mitochondrion [PDF]

, 2020
Toxoplasma gondii’s single mitochondrion is very dynamic and undergoes morphological changes throughout the parasite’s life cycle. During parasite division, the mitochondrion elongates, enters the daughter cells just prior to cytokinesis, and undergoes ...

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

The FEBS Journal, EarlyView.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Toxoplasma gondii in rodents and shrews in Armenia, Transcaucasia

International Journal for Parasitology: Parasites and Wildlife
Toxoplasma gondii infections in small mammals are important because they serve as source of infection for the felids who excrete environmentally resistant oocysts in their feces. Here, the authors sought evidence for T.

Regulation of arginine transport by GCN2 eIF2 kinase is important for replication of the intracellular parasite Toxoplasma gondii [PDF]

, 2019
Toxoplasma gondii is a prevalent protozoan parasite that can infect any nucleated cell but cannot replicate outside of its host cell. Toxoplasma is auxotrophic for several nutrients including arginine, tryptophan, and purines, which it must acquire from ...

Highly divergent apicomplexan cytoskeletons provide additional models for actin biology

The FEBS Journal, EarlyView.
Actin is a highly conserved, abundant and central molecule in eukaryotes. Apicomplexans contain some of the most sequence‐divergent actin cytoskeletons known. This divergence results in overlapping yet different biochemical properties. Here, we highlight the remarkable divergence of the actin cytoskeleton by comparing apicomplexan to classical systems,

INVESTIGATION OF TOXOPLASMA INFECTIONS IN NATIVE POULTRY OF TABRIZ CITY USING ELISA AND INDIRECT IMMUNOFLUORESCENCE METHODS [PDF]

Exploratory Animal and Medical Research, 2017
Toxoplasma gondii is widely distributed in humans and other animals and birds throughout the world. Toxoplasmosis is a common zoonotic infection in the world and in immune-deficient patients, it may cause acute and lethal infection.
