Ischemia and reperfusion injury in kidney transplantation : relevant mechanisms in injury and repair [PDF]

, 2020
Ischemia and reperfusion injury (IRI) is a complex pathophysiological phenomenon, inevitable in kidney transplantation and one of the most important mechanisms for non- or delayed function immediately after transplantation.

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

International 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.

Potential Mechanisms Underlying TGF-β-mediated Complement Activation in Lung Fibrosis [PDF]

, 2017
While our previous studies suggest that limiting bleomycin-induced complement activation suppresses TGF-β signaling, the specific hierarchical interactions between TGF-β and complement in lung fibrosis are unclear.

Complement C3b contributes to Escherichia coli-induced platelet aggregation in human whole blood

Frontiers in Immunology, 2022
IntroductionPlatelets have essential functions as first responders in the immune response to pathogens. Activation and aggregation of platelets in bacterial infections can lead to life-threatening conditions such as arterial thromboembolism or sepsis ...

Age-Related Maculopathy Susceptibility 2 and Complement Factor H Polymorphism and Intraocular Complement Activation in Neovascular Age-Related Macular Degeneration

Ophthalmology Science, 2022
Purpose: To investigate the association of risk alleles in complement factor H (CFH) and age-related maculopathy susceptibility 2 (ARMS2) with complement activation products in the aqueous humor in eyes with neovascular age-related macular degeneration ...

Cancer epithelia-derived mitochondrial DNA is a targetable initiator of a paracrine signaling loop that confers taxane resistance. [PDF]

, 2020
Stromal-epithelial interactions dictate cancer progression and therapeutic response. Prostate cancer (PCa) cells were identified to secrete greater concentration of mitochondrial DNA (mtDNA) compared to noncancer epithelia.

Complement C3 serum levels in anorexia nervosa: a potential biomarker for the severity of disease? [PDF]

, 2011
BackgroundAnorexia nervosa carries the highest mortality rate of any psychiatric disorder. Even the most critically ill anorexic patients may present with normal 'standard' laboratory values, underscoring the need for a new sensitive biomarker.

Elevated complement C3a in plasma from patients with severe acute asthma [PDF]

Journal of Allergy and Clinical Immunology, 2003
Complement component C3a, an anaphylatoxin, provokes acute inflammatory responses, including smooth muscle contraction, mucus hypersecretion, increase in vascular permeability, and recruitment of inflammatory cells. Thus C3a may be related to airway inflammation and bronchoconstriction in acute asthma exacerbation.We sought to determine whether plasma ...

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

Journal 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 ...

Complement C3a Enhances CXCL12 (SDF-1)-Mediated Chemotaxis of Bone Marrow Hematopoietic Cells Independently of C3a Receptor [PDF]

The Journal of Immunology, 2005
Abstract Complement C3a promotes CXCL12-induced migration and engraftment of human and murine hemopoietic progenitor cells, suggesting a cross-influence between anaphylatoxin and chemokine axes. Here we have explored the underlying mechanism(s) of complement anaphylatoxin and chemokine cooperation.
