C3a and Its Receptor C3aR Are Detectable in Normal Human Epidermal Keratinocytes and Are Differentially Regulated via TLR3 and LL37

open access: yesJournal of Innate Immunity, 2021
To study the molecular interplay between TLRs and complement representing ancient danger-sensing mechanisms, we examined the regulation of the C3a/anaphylatoxin C3a receptor (C3aR) axis in normal human epidermal keratinocytes (NHEKs) by treatment with ...

The interaction between circulating complement proteins and cutaneous microvascular endothelial cells in the development of childhood Henoch-Schönlein Purpura. [PDF]

open access: yesPLoS ONE, 2015
In addition to IgA, the deposition of complement (C)3 in dermal vessels is commonly found in Henoch-Schönlein purpura (HSP). The aim of this study is to elucidate the role of circulating complement proteins in the pathogenesis of childhood HSP.Plasma ...

Tissue plasminogen activator mediates deleterious complement cascade activation in stroke. [PDF]

open access: yesPLoS ONE, 2017
The use of intravenous tissue plasminogen activator (tPA) in the treatment of ischemic stroke is limited by its propensity to exacerbate brain edema and hemorrhage. The mechanisms underlying these deleterious effects of tPA remain incompletely understood.

Selective Hexapeptide Agonists and Antagonists for Human Complement C3a Receptor

open access: yes, 2016
Human anaphylatoxin C3a, formed through cleavage of complement protein C3, is a potent effector of innate immunity via activation of its G protein coupled receptor, human C3aR.

Up-regulating CYP3A4 expression in C3A cells by transfection with a novel chimeric regulator of hPXR-p53-AD.

open access: yesPLoS ONE, 2014
Most hepatoma cell lines lack proper expression and induction of CYP3A4 enzyme, which limits their use for predicting drug metabolism and toxicity. Nuclear receptor pregnane X receptor (PXR) has been well recognized for its critical role in regulating ...

Complement C3a treatment accelerates recovery after stroke via modulation of astrocyte reactivity and cortical connectivity

open access: yesThe Journal of Clinical Investigation, 2023
Despite advances in acute care, ischemic stroke remains a major cause of long-term disability. Approaches targeting both neuronal and glial responses are needed to enhance recovery and improve long-term outcome.

Negative regulation of pulmonary Th17 responses by C3a anaphylatoxin during allergic inflammation in mice. [PDF]

open access: yesPLoS ONE, 2012
Activation of complement is one of the earliest immune responses to exogenous threats, resulting in various cleavage products including anaphylatoxin C3a.

Small Molecule-Induced Complement Factor D (Adipsin) Promotes Lipid Accumulation and Adipocyte Differentiation. [PDF]

open access: yesPLoS ONE, 2016
Adipocytes are differentiated by various transcriptional cascades integrated on the master regulator, Pparγ. To discover new genes involved in adipocyte differentiation, preadipocytes were treated with three newly identified pro-adipogenic small ...

The C3aR promotes macrophage infiltration and regulates ANCA production but does not affect glomerular injury in experimental anti-myeloperoxidase glomerulonephritis. [PDF]

open access: yesPLoS ONE, 2018
The anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitides are autoimmune diseases associated with significant morbidity and mortality. They often affect the kidney causing rapidly progressive glomerulonephritis.
