Navigating adverse immunostimulation: A practical guide for clinical researchers

British Journal of Clinical Pharmacology, EarlyView.
Problem Setting As drug development moves towards more complex products, early clinical development programmes are increasingly hampered by unwanted and/or unexpected activation of the immune system (adverse immune stimulation, AIS). Solution At the Centre for Human Drug Research, we have introduced standardized procedures to make AIS manageable, while

A dual receptor crosstalk model of G-protein-coupled signal transduction. [PDF]

PLoS Computational Biology, 2008
Macrophage cells that are stimulated by two different ligands that bind to G-protein-coupled receptors (GPCRs) usually respond as if the stimulus effects are additive, but for a minority of ligand combinations the response is synergistic.

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

BMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

Cloning of the Human C5a Anaphylatoxin Receptor, and More [PDF]

Frontiers in Immunology, 2015
The initial observation in 1973 that the complement C5 activation product, C5a, has the ability to stimulate human neutrophils led to the concept of a specific C5a receptor (1). In the mid-1986, a groundbreaking paper published in Nature announced the cloning of the beta-adrenergic receptor, and for the first time established seven transmembrane (7TM ...

Gut microbiota‐related modulation of immune mechanisms in post‐infarction remodelling and heart failure

ESC Heart Failure, Volume 12, Issue 2, Page 942-954, April 2025.
Abstract The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro‐inflammatory and ...

Complement C5a Induces Pro-inflammatory Microvesicle Shedding in Severely Injured Patients

Frontiers in Immunology, 2020
Initially underestimated as platelet dust, extracellular vesicles are continuously gaining interest in the field of inflammation. Various studies addressing inflammatory diseases have shown that microvesicles (MVs) originating from different cell types ...

Inhibition of C5a-induced neutrophil chemotaxis and macrophage cytokine production In vitro by a new C5a receptor antagonist

, 2000
A cyclic peptide, Phe-[Orn-Pro-D-Cyclohexylalanine-Trp-Arg] (F-[OPdChaWR]), was recently shown in vitro to antagonise the binding of C5a to its receptor (CD88) on human polymorphonuclear leukocytes (PMNs) and in vivo to inhibit the neutropenia associated

Prenatal betamethasone–postnatal N‐methyl‐D‐aspartic acid model of spasms: Update on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...

Cross‐protective effect of a multicomponent fusion protein vaccine during a natural episode of Streptococcus zooepidemicus respiratory disease in ponies

Equine Veterinary Journal, EarlyView.
Abstract Background Streptococcus equi subspecies zooepidemicus is a highly diverse opportunistic pathogen of horses, associated with respiratory disease and endometritis. Objectives To characterise S. zooepidemicus isolates recovered from young ponies during a natural episode of respiratory disease, and to determine if vaccination with Strangvac®, a ...

The orphan receptor C5L2 has high affinity binding sites for complement fragments C5a and C5a des-Arg74

, 2002
The substantial variations in the responses of cells to the anaphylatoxin C5a and its desarginated form, C5adR74, suggest that more than one type of cell surface receptor for these ligands might exist. However, only a single receptor for C5a and C5adR74,
