Complement C5a‐triggered differentiated HL‐60 stimulates migration of THP‐1 monocytic leukocytes via secretion of CCL2

open access: yesFEBS Open Bio, 2021
Leukocytes play an important role in vascular inflammation prior to atherosclerosis. In particular, monocyte adhesion and migration to the endothelium contribute to the development of vascular inflammation.

Functions of C5a receptors [PDF]

open access: yesJournal of Molecular Medicine, 2009
The split product of the complement protein, C5, is C5a and is an extremely potent pro-inflammatory peptide that interacts with two C5a receptors, C5aR and C5L2, present on surfaces of phagocytes as well as other cell types. The former is a well-established receptor that initiates G-protein-coupled signaling via mitogen-activated protein kinase ...

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

The Role of Formylpeptide Receptors, C5a Receptors, and Cytosolic-Free Calcium in Neutrophil Priming [PDF]

open access: yes, 1990
Polymorphonuclear leukocytes (PMNL) exposed to chemoattractants or cytokines change their functional capacity. The effect of endotoxin-activated serum as a priming agent on human PMNL was tested.

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

Determination of C5a-specific antibody levels and C5a neutralization.

open access: yes, 2013
Anti-C5a antibody levels (A) in the sera collected from mice on day 35 immunized for CIA. As described in Fig. 1B, (BALB/c x B10.Q) F1 male mice (8 weeks old) received vaccination subcutaneously of 100 µg MBP-C5a or PBS emulsified in CFA at day −21 and ...

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.

CD177 Deficiency Defines a Stable Subtype of Human Neutrophil Granulocytes with Tumor Promoting Activity

open access: yesAdvanced Science, EarlyView.
Human neutrophils exist as two epigenetically imprinted subtypes defined by stable CD177 expression or absence — a ratio that persists across time, circadian rhythms, and inflammation. CD177− neutrophils display a distinct molecular landscape enriched in arginase 1 and lipid metabolism markers, accumulate in head‐and‐neck tumors, and associate with ...
