Determinants of GBP Recruitment to Toxoplasma gondii Vacuoles and the Parasitic Factors That Control It

open access: yesPLoS ONE, 2011
IFN-γ is a major cytokine that mediates resistance against the intracellular parasite Toxoplasma gondii. The p65 guanylate-binding proteins (GBPs) are strongly induced by IFN-γ. We studied the behavior of murine GBP1 (mGBP1) upon infection with T. gondii

The Formation and Features of Massive Vacuole Induced by Nutrient Deficiency in Human Embryonic Kidney Cells

open access: yesFrontiers in Bioscience-Landmark
Background: Cellular vacuolization is a commonly observed phenomenon under physiological and pathological conditions. However, the mechanisms underlying vacuole formation remain largely unresolved.

Legionella RavZ Plays a Role in Preventing Ubiquitin Recruitment to Bacteria-Containing Vacuoles

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Bacterial pathogens like Salmonella and Legionella establish intracellular niches in host cells known as bacteria-containing vacuoles. In these vacuoles, bacteria can survive and replicate.

Disruption of Toxoplasma gondii Parasitophorous Vacuoles by the Mouse p47-Resistance GTPases

open access: yesPLoS Pathogens, 2005
The p47 GTPases are essential for interferon-γ-induced cell-autonomous immunity against the protozoan parasite, Toxoplasma gondii, in mice, but the mechanism of resistance is poorly understood. We show that the p47 GTPases, including IIGP1, accumulate at

Expert Perspectives on a Clinical Challenge: Hematologic Malignancies and Vasculitis

open access: yesArthritis &Rheumatology, Accepted Article.
Systemic vasculitis describes a collection of rare diseases each caused by inflammation of blood vessel walls that can cause severe systemic complications [[3, 4]](#ref‐0003). The pattern of vascular inflammation and resultant damage is frequently variable and may be mimicked, or directly triggered, by infection or malignancy.

Cell vacuolation induced by Haemophilus influenzae supernatants in HEp-2 cells

open access: yesMemorias do Instituto Oswaldo Cruz, 2013
Haemophilus influenzae belongs to respiratory tract microbiota. We observed vacuoles formation in previous studies with H. influenzae culture supernatants, so in this work we characterised that cytotoxic effect.

Vacuoles: a hollow threat? [PDF]

open access: yesCanadian Journal of Anesthesia/Journal canadien d'anesthésie, 2010
In this issue of the Journal, Bawolak et al.1 focus their studies on a mechanism that provides a provocative insight into the complexity of systems that organize the intracellular environment. This mechanism may also serve to describe the effects produced by agents that are applied in high concentrations to the outer membrane of the cell… in this case,

Regulation mechanisms and signaling pathways of autophagy.

open access: yesAnnual Review of Genetics, 2009
Autophagy is a process of self-degradation of cellular components in which double-membrane autophagosomes sequester organelles or portions of cytosol and fuse with lysosomes or vacuoles for breakdown by resident hydrolases.

Characteristics of weak base-induced vacuoles formed around individual acidic organelles

open access: yesFolia Histochemica et Cytobiologica, 2011
We have previously found that the weak base 4-aminopyridine induces Brownian motion of acidic organelles around which vacuoles are formed, causing organelle traffic disorder in neurons.

An investigation of the potential effect of vacuoles in human sperm on DNA damage using a chromosome assay and the TUNEL assay.

open access: yesHuman Reproduction, 2011
BACKGROUND The aims of this study were to establish whether individual differences exist in the frequency and size of vacuoles found in human sperm and to ascertain whether such vacuoles are involved in causing DNA damage.
