An immune-adrenergic pathway induces lethal levels of platelet-activating factor in mice

Communications Biology
Acute immune responses with excess production of cytokines, lipid/chemical mediators, or coagulation factors, often result in lethal damage. In addition, the innate immune system utilizes multiple types of receptors that recognize neurotransmitters as ...

Expression of a splice variant of the platelet-activating factor receptor transcript 2 in various human cancer cell lines

Mediators of Inflammation, 2002
Platelet-activating factor receptor (PAF-R) transcripts were analysed by reverse transcriptase-polymerase chain reaction in five human cancer cell lines derived from the breast (BT20, SKBR3 and T47D cells), the pancreas (Miapaca cells) and the bladder ...

Tricarboxylic Acid Cycle Activity and Remodeling of Glycerophosphocholine Lipids Support Cytokine Induction in Response to Fungal Patterns

Cell Reports, 2019
Summary: Increased glycolysis parallels immune cell activation, but the role of pyruvate remains largely unexplored. We found that stimulation of dendritic cells with the fungal surrogate zymosan causes decreases of pyruvate, citrate, itaconate, and α ...

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Involvement of Platelet Activating Factor (PAF) in various Diseases

, 2023
<p><i>Platelet Activating Factor (PAF) is a lipid compound, glyceryl ether analog of phosphatidylcholine. PAF through its binding to a well-characterized receptor initiates a multitude of cellular pro-inflammatory actions that are thus ...

Insights Into the Role of Platelet Factor 4 in Neurodegenerative Diseases

CNS Neuroscience &Therapeutics, Volume 32, Issue 10, October 2026.
This review summarizes potential functions of platelet factor 4 (PF4) in neurodegenerative diseases (NDs) and discusses its promise as both a biomarker and a therapeutic target. Further elucidation of PF4 signaling pathways may provide new insights into disease mechanisms and uncover novel opportunities for targeted interventions in NDs.
