Comparison of Porcine Hepatocytes with Human Hepatoma (C3A) Cells for Use in a Bioartificial Liver Support System

open access: yesCell Transplantation, 1998
Cells from primary porcine hepatocytes (PPH) and the immortalized human hepatoma cell line C3A are both used in bioartificial liver support systems (BALSS).

Preservation of Antimicrobial Properties of Complement Peptide C3a, from Invertebrates to Humans [PDF]

open access: yesJournal of Biological Chemistry, 2007
The human anaphylatoxin peptide C3a, generated during complement activation, exerts antimicrobial effects. Phylogenetic analysis, sequence analyses, and structural modeling studies paired with antimicrobial assays of peptides from known C3a sequences showed that, in particular in vertebrate C3a, crucial structural determinants governing antimicrobial ...

Complement 3a Mediates CCN2/CTGF in Human Retinal Pigment Epithelial Cells

open access: yesJournal of Ophthalmology, 2022
Background. Complement 3 (C3) is the crucial component of the complement cascade when retina was exposed to external stimulus. Cellular communication network 2/connective tissue growth factor (CCN2/CTGF) is important in response of retinal stress and a ...

Complement C3a and C5a Induce Different Signal Transduction Cascades in Endothelial Cells [PDF]

open access: yesThe Journal of Immunology, 2002
Abstract In leukocytes, C3a and C5a cause chemotaxis in a Gi-dependent, pertussis toxin (PT)-sensitive fashion. Because we found that HUVECs and immortalized human dermal microvascular endothelial cells express small numbers of C3aRs and C5aRs, we asked what the function of these receptors was on these cells.

Erythropoietin Effect on Complement Activation in Chronic Kidney Disease

open access: yesBiomedicines
The complement system is an important part of innate immunity. Despite its known protective role, the complement system may contribute to increased inflammation and tissue injury in cases where its balanced activation is disrupted.

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 ...

The Complement C3a And C3a Receptor Pathway Indiabetic Patients With Entamobra Histolytica, Cryptospridium Parvum

open access: yesInternational Journal of Environmental Sciences
Cryptosporidium parvum and Entamoeba histolytica are significant protozoan parasites that adversely impact human health. The infection rate of these parasites among diabetic patients was recorded at 18.33%. However, the mechanisms underlying host-parasite interactions remain poorly understood.

Indoor microbial exposure increases complement component C3a and C-reactive protein concentrations in serum

open access: yesHeliyon
Indoor exposure to microbial growth, caused by moisture damage, has been an established health risk for several decades. It is likely that a damp indoor environment contains biological pollutants that trigger both the innate and adaptive branches of the ...

Exploiting a novel conformational switch to control innate immunity mediated by complement protein C3a

open access: yesNature Communications, 2017
Complement C3a is an important protein in innate and adaptive immunity, but its roles in vivo are unclear. Here the authors develop novel chemical agonists and antagonists for the C3a receptor, and show that they modulate mast cell degranulation and ...
