Effects of aqueous leaf extracts of Azadirachta indica A. Juss. (neem) and Melia azedarach L. (Santa Barbara or cinnamon) on the intracellular development of Toxoplasma gondii Efeito de extrato aquoso de folhas de Azadirachta indica A. Juss. (nim) e Melia azedarach L. (canela ou Santa Bárbara) sobre o desenvolvimento intracelular de Toxoplasma gondii

Revista Brasileira de Plantas Medicinais, 2011
Melia azedarach (cinnamon) and Azadirachta indica (neem) have a variety of biologically active ingredients against virus, bacteria and protozoan parasites; however, little is known about their action on Toxoplasma gondii intracellular development ...

MyD88 Deficiency Protects Mice From Experimental Autoimmune Encephalomyelitis by Influencing Both Dendritic Cells and T Cells

Immunology, EarlyView.
This study investigates the role of MyD88 in dendritic cells (DCs) and T cells during experimental autoimmune encephalomyelitis (EAE). We found that MyD88 is highly expressed in DCs and CD4+ T cells in people with multiple sclerosis, and its deficiency impairs DC maturation, reduces pro‐inflammatory cytokine production, weakens DC–T cell interactions ...

Host lipid droplets: An important source of lipids salvaged by the intracellular parasite Toxoplasma gondii

PLoS Pathogens, 2017
Toxoplasma is an obligate intracellular parasite that replicates in mammalian cells within a parasitophorous vacuole (PV) that does not fuse with any host organelles.

Epidemiological investigation into abortion in farmed red deer in New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Veterinary Sciences at Massey University, Palmerston North, New Zealand [PDF]

, 2016
Reproductive performance in rising two-year-old (R2) and mixed-aged (MA) adult hinds is suboptimal in farmed red deer in New Zealand due to failure to conceive, fetal loss, and perinatal and postnatal mortality.

High levels of congenital transmission of toxoplasma gondii in longitudinal and cross-sectional studies on sheep farms provides evidence of vertical transmission in ovine hosts [PDF]

, 2005
Recent research suggests that vertical transmission may play an important role in sustaining Toxoplasma gondii infection in some species. We report here that congenital transmission occurs at consistently high levels in pedigree Charollais and outbred ...

Imaging malaria parasites across scales and time

Journal of Microscopy, EarlyView.
Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.

Three Toxoplasma gondii Dense Granule Proteins Are Required for Induction of Lewis Rat Macrophage Pyroptosis

mBio, 2019
Inflammasomes are major components of the innate immune system and are responsible for detecting various microbial and environmental danger signals. Upon invasion of Lewis rat macrophages, the parasite rapidly activates the NLRP1 inflammasome, resulting ...

Vaccines against toxoplasma gondii : challenges and opportunities [PDF]

, 2009
Development of vaccines against Toxoplasma gondii infection in humans is of high priority, given the high burden of disease in some areas of the world like South America, and the lack of effective drugs with few adverse effects.

Artificial intelligence‐powered microscopy: Transforming the landscape of parasitology

Journal of Microscopy, EarlyView.
Abstract Microscopy and image analysis play a vital role in parasitology research; they are critical for identifying parasitic organisms and elucidating their complex life cycles. Despite major advancements in imaging and analysis, several challenges remain. These include the integration of interdisciplinary data; information derived from various model
