Tracking autophagy during proliferation and differentiation of Trypanosoma brucei

William R. Proto1, Nathaniel G. Jones1, Graham H. Coombs2, and Jeremy C. Mottram1

This article provides insights into the function of autophagy, a cellular degradation and recycling pathway, in the protozoan parasite Trypanosoma brucei.

Clostridium scindens promotes gallstone formation by inducing intrahepatic neutrophil extracellular traps through CXCL1 produced by colonic epithelial cells

March 19, 2025

Through in vivo and in vitro experiments, we validated the reliability of C. scindens stimulating colonic epithelial cells to produce TLR2, activating the NF-κB signaling pathway, promoting CXCL1 expres-sion, and inducing intrahepatic neutrophil NETosis, which may be associated with gallstone formation.

Integrative Omics reveals changes in the cellular landscape of peroxisome-deficient pex3 yeast cells

February 20, 2025

To uncover the consequences of peroxisome deficiency, we compared Saccharomyces cerevisiae wild-type with pex3 cells, which lack peroxisomes, employing quantitative proteomics and transcriptomics technologies.

A complex remodeling of cellular homeostasis distinguishes RSV/SARS-CoV-2 co-infected A549-hACE2 expressing cell lines

October 8, 2024

Given the common tropism of SARS-CoV-2 and RSV, and the unclear consequences of their mutual influence, we developed an in vitro lung epithelial cell model to study the molecular mechanisms and cellular pathways modulated in viral co-infection.

RidA proteins contribute to fitness of S. enterica and E. coli by reducing 2AA stress and moderating flux to isoleucine biosynthesis

October 4, 2024

This study solidifies the established role of RidA in removing 2AA, while also presenting evidence for a role of RidA in enhancing flux towards isoleucine biosynthesis in E. coli. Overall, these data emphasize that metabolic networks can generate distinct responses to perturbation, even when the individual components are conserved.

Fecal gelatinase does not predict mortality in patients with alcohol-associated hepatitis

August 26, 2024

This study aimed to investigate the significance of fecal gelatinase on clinical outcomes in patients with alcohol-associated hepatitis. In conclusion, in our cohort, fecal gelatinase does not predict mortality and does not indicate higher disease severity in patients with alcohol-associated hepatitis.

Promoter methylation and increased expression of PD-L1 in patients with active tuberculosis

July 29, 2024

The PD-1/PD-L1 pathway plays a pivotal role in T cell activity and is involved in the pathophysiology of tuberculosis. Here we show that PD-L1 expression is increased in patients with active tuberculosis and is correlated with treatment outcomes.

Quantification methods of Candida albicans are independent irrespective of fungal morphology

July 26, 2024

Our study demonstrated that the quantification methods of C. albicans (cells/mL, CFU/mL, and vPCR) did not agree, regardless of the fungal morphology/growth, even though a significant and strong correlation is observed.

Pathogenic Escherichia coli change the adhesion between neutrophils and endotheliocytes in the experimental bacteremia model

July 22, 2024

In this work, we have demonstrated that in the model of experimental septicemia there is a disruption of adhesion contacts between neutrophils and endothelial cells, manifested by a decrease in adhesion force and work upon exposure to E. coli.

Arsenite treatment induces Hsp90 aggregates distinct from conventional stress granules in fission yeast

July 19, 2024

Given the conserved role of Hsp90 as a molecular chaperone protein, our findings presented in this study may suggest a novel type of arsenite-induced biological condensates, wherein Hsp90 plays a key role in maintaining its integrity.

Expansion of metabolically labelled endocytic organelles and cytoskeletal cell structures in Giardia lamblia using optimised U- ExM protocols

June 21, 2024

Understanding cellular ultrastructure is tightly bound to microscopic resolution and the ability to identify individual components at that resolution. In this study we demonstrate mostly isotropic 4.5-fold expansion of several different compartments in Giardia cells and present an optimised, shortened, and modular protocol that can be swiftly adjusted to the investigators needs.
