C5a enhances dysregulated inflammatory and angiogenic responses to malaria in vitro: potential implications for placental malaria. [PDF]

PLoS ONE, 2009
Placental malaria (PM) is a leading cause of maternal and infant mortality. Although the accumulation of parasitized erythrocytes (PEs) and monocytes within the placenta is thought to contribute to the pathophysiology of PM, the molecular mechanisms ...

Increased Levels of C5a in Gingival Crevicular Fluid and Saliva of Patients with Periodontal Disease

, 2022
C5a is a powerful complement effector molecule that is considered to be an important proinflammatory mediator in several systemic chronic inflammatory diseases. However, its levels in periodontal diseases are yet to be assessed.

A disturbed balance between blood complement protective factors (FH, ApoE) and common pathway effectors (C5a, TCC) in acute COVID-19 and during convalesce

Scientific Reports, 2022
A complement effect on homeostasis during infection is determined by both cytotoxic (activate complement component 5 (C5a) terminal cytotoxic complex (TCC)), and cytoprotective elements (complement factor H (FH), as well as apolipoprotein E (ApoE)). Here,

TLR activation enhances C5a-induced pro-inflammatory responses by negatively modulating the second C5a receptor, C5L2 [PDF]

, 2011
TLR and complement activation ensures efficient clearance of infection. Previous studies documented synergism between TLRs and the receptor for the pro-inflammatory complement peptide C5a (C5aR/CD88), and regulation of TLR-induced pro-inflammatory ...

Distinct roles of the anaphylatoxin receptors C3aR, C5aR1 and C5aR2 in experimental meningococcal infections

Virulence, 2019
The complement system is pivotal in the defense against invasive disease caused by Neisseria meningitidis (Nme, meningococcus), particularly via the membrane attack complex.

The complement anaphylatoxin C5a induces apoptosis in adrenomedullary cells during experimental sepsis. [PDF]

PLoS ONE, 2008
Sepsis remains a poorly understood, enigmatic disease. One of the cascades crucially involved in its pathogenesis is the complement system. Especially the anaphylatoxin C5a has been shown to have numerous harmful effects during sepsis.

The amino terminus of the human C5a receptor is required for high affinity C5a binding and for receptor activation by C5a but not C5a analogs.

Journal of Biological Chemistry, 1994
The binding domain of the human C5a receptor consists of two distinct and physically separable subsites. One of these sites binds the C-terminal 8 amino acids of C5a and is as yet undefined, while the second site lies in the N terminus of the receptor and interacts with the core of C5a. Two deletion mutants were prepared to probe the importance of this

Macrophage migration inhibitory factor is involved in antineutrophil cytoplasmic antibody-mediated activation of C5a-primed neutrophils

BMC Immunology, 2019
Background C5a is important for antineutrophil cytoplasmic antibody (ANCA)-mediated activation of neutrophils. The present study aimed to assess the role of macrophage migration inhibitory factor (MIF) in ANCA-mediated activation of C5a-primed ...
