PPAR beta/delta activation of CD300a controls intestinal immunity

Macrophages are important for maintaining intestinal immune homeostasis. Here, we show that PPAR beta/delta (peroxisome proliferator-activated receptor beta/delta) directly regulates CD300a in macrophages that express the immunoreceptor tyrosine based-inhi ...

Kinetic reconstruction and analysis of sphingolipid metabolism

Vassily Hatzimanikatis, Howard Riezman, Georgios Savoglidis

Lipids are major constituents of the cell. They are responsible for major properties of the cellular membranes: hydrophobicity, selective permeability and being the scaffold of signaling proteins. Many diseases are associated with alterations in the lipid ...

A comprehensive reconstruction of the fatty acid biosynthesis in Saccharomyces cerevisiae

Vassily Hatzimanikatis, Georgios Savoglidis, Iro Oikonomidi

The role of lipids in eukaryotic cells is of high importance. They are one of the main components of cell membranes, act as storage of high potential energy as well as being a scaffold of signaling proteins or participate in signaling themselves. Many dise ...

MicroRNA-22 (miR-22) Overexpression Is Neuroprotective via General Anti-Apoptotic Effects and May also Target Specific Huntington's Disease-Related Mechanisms

Ana Jovicic

Background: Whereas many causes and mechanisms of neurodegenerative diseases have been identified, very few therapeutic strategies have emerged in parallel. One possible explanation is that successful treatment strategy may require simultaneous targeting o ...

Activation and Spatial Organization of the Adenosine A2A Receptor in Supported Plasma Membrane Sheets

Sophie Roizard

G protein-coupled receptors (GPCRs) are ubiquitous mediators of signal transduction across cell membranes and constitute a very important class of therapeutic targets. The main mechanisms involving GPCR activation and signal transduction to the cell interi ...

Integrating omics data into metabolic models of lipids: a platform for the identification of gene mutations from lipidomics data

Vassily Hatzimanikatis, Paolo Angelino, Howard Riezman, Georgios Savoglidis

Kinetic models of metabolic networks are mapping the biochemical reactions taking part in a cell to a mathematical representation. They are the blueprints of the biochemical network, connecting enzymatic activities and metabolic compounds. Kinetic models h ...

The role of CDX2 in Caco-2 cell differentiation

Pascale Anderle Pedone

Background: CDX2 plays a key part in the differentiation of Caco-2 cells, a colon carcinoma derived cell line that undergoes spontaneous differentiation. The effect of CDX2 expression in Caco-2 cells over time in culture has not been studied yet on a genom ...

The Mucosal Adjuvant Cholera Toxin B Instructs Non-Mucosal Dendritic Cells to Promote IgA Production Via Retinoic Acid and TGF-β

Nicola Harris

It is currently unknown how mucosal adjuvants cause induction of secretory immunoglobulin A (IgA), and how T cell-dependent (TD) or -independent (TI) pathways might be involved. Mucosal dendritic cells (DCs) are the primary antigen presenting cells driving ...

Binding of Lassa virus perturbs extracellular matrix-induced signal transduction via dystroglycan

Françoise Gisou van der Goot Grunberg, Marie-Laurence Moraz, Stefan Kunz, Christelle Pythoud

The arenavirus Lassa virus (LASV) causes a severe haemorrhagic fever with high mortality in man. The cellular receptor for LASV is dystroglycan (DG). DG is a ubiquitous receptor for extracellular matrix (ECM) proteins, which cooperates with beta 1 integrin ...

Secreted semaphorin 5A suppressed pancreatic tumour burden but increased metastasis and endothelial cell proliferation

Anguraj Sadanandam, Stephan Wullschleger

BACKGROUND: Our earlier reports demonstrated that membrane-bound semaphorin 5A (SEMA5A) is expressed in aggressive pancreatic cancer cells and tumours, and promotes tumour growth and metastasis. In this study, we examine whether (1) pancreatic cancer cells ...
