Complement effectors, C5a and C3a, in cystic fibrosis lung fluid correlate with disease severity. [PDF]

PLoS ONE, 2017
In cystic fibrosis (CF), lung damage is mediated by a cycle of obstruction, infection, inflammation and tissue destruction. The complement system is a major mediator of inflammation for many diseases with the effectors C5a and C3a often playing important

Adverse immunostimulation in early phase clinical trials: Key findings and recommendations based on the investigator's clinical experience

British Journal of Clinical Pharmacology, EarlyView.
Problem setting The emergence of therapeutic proteins has coincided with an increase of acute adverse immunostimulation (AIS). AIS has occured in clinical trials despite compliance with regulatory guidelines on preclinical evaluation and its incidence is anticipated to increase even further.

Changes in complement activation products after anti-VEGF injection for choroidal neovascularization in age-related macular degeneration and pachychoroid disease

Scientific Reports, 2021
We evaluated changes in the complement system resulting from anti-vascular endothelial growth factor (VEGF) in eyes with age-related choroidal neovascularization (CNV) including neovascular age-related macular degeneration, pachychoroid neovasculopathy ...

Bioresponsive pseudoGlucosinolates (psGSLs) Release Isothiocyanates (ITCs) in the Presence of Nitroreductases

Chemistry – A European Journal, EarlyView.
This work introduces the concept of pseudoglucosinolates (psGSLs) and reports the synthesis and evaluation of nitroreductase‐responsive psGSLs. These compounds represent a complementary prodrug strategy to natural glucosinolates (GSLs) for the controlled release of isothiocyanates (ITCs), enabling bio‐responsive protein labeling, as demonstrated in ...

Antimicrobial peptides and complement in neonatal hypoxia-ischemia induced brain damage [PDF]

, 2015
Hypoxic-ischemic encephalopathy (HIE) is a clinical condition in the neonate, resulting from oxygen deprivation around the time of birth. HIE affects 1-5/1000 live births worldwide and is associated with the development of neurological deficits ...

C3a is made by proximal tubular HK-2 cells and activates them via the C3a receptor [PDF]

Kidney International, 1999
Some individual components of complement are synthesized by the kidney. However, it is not known whether these form functional pathways that are able to mediate more fundamental cellular events. We examined the ability of HK-2 tubular cells to produce an intact alternative pathway of complement and to respond to the C3a fragment thus produced through ...

Prediction of Acute Liver Injury Trajectory in Patients Following Acetaminophen Overdose: A Multibiomarker Machine Learning Proof‐of‐Concept Study

Clinical Pharmacology &Therapeutics, EarlyView.
Clinical translation of novel therapies can be hindered by heterogeneity‐driven sample size inflation in late‐stage trials. In acetaminophen‐induced liver injury (APAP DILI), many patients recover spontaneously, diluting investigational drug efficacy signals.

C3a receptor antagonist ameliorates inflammatory and fibrotic signals in type 2 diabetic nephropathy by suppressing the activation of TGF-β/smad3 and IKBα pathway.

PLoS ONE, 2014
ObjectiveDiabetic nephropathy (DN) is a serious complication for patients with diabetes mellitus (DM). Emerging evidence suggests that complement C3a is involved in the progression of DN.

Anaphylatoxins Activate Ca2+, Akt/PI3-Kinase, and FOXO1/FoxP3 in the Retinal Pigment Epithelium

Frontiers in Immunology, 2017
PurposeThe retinal pigment epithelium (RPE) is a main target for complement activation in age-related macular degeneration (AMD). The anaphylatoxins C3a and C5a have been thought to mostly play a role as chemoattractants for macrophages and immune cells;
