Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Electrochemical regulation of budding yeast polarity.

open access: yesPLoS Biology, 2014
Cells are naturally surrounded by organized electrical signals in the form of local ion fluxes, membrane potential, and electric fields (EFs) at their surface.

Characterization of Phosphatidylserine Transport to the Locus of Phosphatidylserine Decarboxylase 2 in Permeabilized Yeast [PDF]

open access: yesJournal of Biological Chemistry, 2001
In yeast, nascent phosphatidylserine (PtdSer) can be transported to the mitochondria and Golgi/vacuole for decarboxylation to synthesize phosphatidylethanolamine (PtdEtn). In strains with a psd1Delta allele for the mitochondrial PtdSer decarboxylase, the conversion of nascent PtdSer to PtdEtn can serve as an indicator of lipid transport to the locus of

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Interaction between Phosphatidylserine and the Phosphatidylserine Receptor Inhibits Immune Responses In Vivo [PDF]

open access: yesThe Journal of Immunology, 2005
Abstract Phosphatidylserine (PS) on apoptotic cells promotes their uptake and induces anti-inflammatory responses in phagocytes, including TGF-β release. Little is known regarding the effects of PS on adaptive immune responses. We therefore investigated the effects of PS-containing liposomes on immune responses in mice in vivo.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Essential lipid autacoids rewire mitochondrial energy efficiency in metabolic dysfunction‐associated fatty liver disease

open access: yesHepatology, EarlyView., 2022
Increased liver content of DHA‐derived small lipid autacoids (i.e resolvin D1 and maresin 1) associates with enhanced mitochondrial oxidative phosphorylation, fatty acid β‐oxidation and bioenergetic metabolic flux. These features provide hepatic protection from steatotic, pro‐inflammatory and fibrogenic insults.

In vitro Evaluation of Cytarabin Induced Apoptosis in Leukemic Blasts

open access: yesIranian Journal of Allergy, Asthma and Immunology, 2005
Apoptosis, or active cell death, is a specific mode of cell death, which is characterized by morphological changes such as chromatin condensation, fragmentation of the nucleus, cytoplasmic retraction and appearance of apoptotic bodies' containing ...

A141

open access: yesEJC Supplements, 2015
The aim of this study was to investigate the quantitative changes in the phospholipid (PL) content of peripheral blood mononuclear cells (MNC), plasma membrane (PM), fraction in breast (BC) and cervical cancers (CC) compared to normal levels.

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

open access: yesFEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...
