A novel class of broad-spectrum active-site-directed 3C-like protease inhibitors with nanomolar antiviral activity against highly immune-evasive SARS-CoV-2 Omicron subvariants

open access: yesEmerging Microbes and Infections, 2023
Antivirals with broad coronavirus activity are important for treating high-risk individuals exposed to the constantly evolving SARS-CoV-2 variants of concern (VOCs) as well as emerging drug-resistant variants. We developed and characterized a novel class

Processing of C5a by human polymorphonuclear leukocytes [PDF]

open access: yes, 1998
Uptake of human C5a by neutrophils was monitored in vitro using both 125I-labeled and unlabeled C5a. The ligand was internalized by the cells in a dose-dependent manner and maximal binding/uptake was observed after 5 min of incubation.

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

open access: yesPLoS 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

Modeling Molecular Mechanisms of Binding of the Anaphylatoxin C5a to the C5a Receptor [PDF]

open access: yes, 2016
This study presents the 3D model of the complex between the anaphylatoxin C5a and its specific receptor, C5aR. This is the first 3D model of a G-protein-coupled receptor (GPCR) complex with a peptide ligand deduced by a molecular modeling procedure ...

Site‐specific mutations in the N‐terminal region of human C5a that affect interactions of C5a with the neutrophil C5a receptor [PDF]

open access: yesProtein Science, 1993
AbstractC5a is an inflammatory mediator that evokes a variety of immune effector functions including chemotaxis, cell activation, spasmogenesis, and immune modulation. It is well established that the effector site in C5a is located in the C‐terminal region, although other regions in C5a also contribute to receptor interaction.

The role of the host—Neutrophil biology

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Pro-inflammatory regulatory mechanism of C5a/C5aR pathway in GCRV-infected grass carp (Ctenopharyngodon idella)

open access: yesAquaculture Reports, 2023
Death of grass carp (Ctenopharyngodon idella) caused by grass carp reovirus (GCRV) infection severely restricts the development of the grass carp industry.

C5aR activation in the absence of C5a [PDF]

open access: yes, 2022
S.696-704IgG Fc receptors (FcgRs) and the C5a anaphylatoxin receptor (C5aR) were identified as key regulators of type II autoimmune injury in mice. However, and with respect to C5aR, the relative importance of C5a for IgG autoantibody‐induced ...

FGL2‐HDAC11 Drives Immunothrombosis via NETs‐Mediated Endothelial Capillarization in MASLD Fibrosis

open access: yesAdvanced Science, EarlyView.
ABSTRACT Metabolic dysfunction–associated steatotic liver disease (MASLD) is frequently accompanied by hepatic fibrosis and systemic cardiovascular complications; however, the mechanistic interplay between coagulation abnormalities and disease progression remains poorly defined.
