Protective immune response against Rhodococcus equi: An innate immunity‐focused review

open access: yesEquine Veterinary Journal, Volume 57, Issue 3, Page 563-586, May 2025.
Abstract Rhodococcus equi causes pyogranulomatous pneumonia in foals and immunocompromised people. Despite decades of research efforts, no vaccine is available against this common cause of disease and death in foals. The purpose of this narrative review is to summarise the current understanding of interactions between R. equi and the host innate immune

HS1BP3 negatively regulates autophagy by modulation of phosphatidic acid levels

open access: yesNature Communications, 2016
A fundamental question is how autophagosome formation is regulated. Here we show that the PX domain protein HS1BP3 is a negative regulator of autophagosome formation. HS1BP3 depletion increased the formation of LC3-positive autophagosomes and degradation

Phosphatidic acid induces cytoskeletal rearrangements through the Src‐FAK‐RhoA/ROCK signaling pathway during decidualization

open access: yesThe FEBS Journal, EarlyView.
Decidualization is the process by which human endometrial stromal cells undergo morphological and functional changes to prepare the uterus for embryo implantation and support pregnancy. Our study identifies the phosphatidic acid‐Src‐FAK‐RhoA/ROCK signaling pathway as a critical regulator of the cytoskeletal alterations required for this transformation.

LC‐MS and High‐Throughput Data Processing Solutions for Lipid Metabolic Tracing Using Bioorthogonal Click Chemistry

open access: yesAngewandte Chemie, Volume 137, Issue 27, July 1, 2025.
This study introduces an integrated analytical and bioinformatics platform for high‐throughput tracing of lipid metabolism using bioorthogonal alkyne fatty acids and optimized LC‐MS workflow. Applied to human fibrosarcoma cells, the method traced fatty acid metabolism, revealing nuances in sphingolipid routing and metabolic bottlenecks, highlighting ...

A signal transduction blind spot: the function of adenylyl cyclase transmembrane domains

open access: yesThe FEBS Journal, EarlyView.
Transmembrane adenylyl cyclases (tmACs) are essential for synthesising the universal second messenger cyclic AMP. All tmACs share a common topology that includes a large 12‐helix transmembrane (TM) domain. This domain accounts for ~ 35% of the coding sequence but its function is still an open question.

A comparative study of eicosapentaenoic acid metabolism by human platelets in vivo and in vitro.

open access: yesJournal of Lipid Research, 1985
During long-term dietary n-3 fatty acid supplementation, eicosapentaenoic acid (EPA) is not incorporated into phosphatidylinositol or -serine of human platelets in vivo and is not detectable in phosphatidic acid upon stimulation with thrombin.

A Chemoenzymatic Strategy for Imaging Cellular Phosphatidic Acid Synthesis.

open access: yesAngewandte Chemie, 2016
Phosphatidic acid (PA) is a potent lipid secondary messenger, the synthesis of which is tightly regulated in both space and time. Established tools for detecting PA involve ex vivo analysis and do not provide information on the subcellular locations ...
