Overexpression of complement C5a indicates poor survival and therapeutic response in metastatic renal cell carcinoma

The International Journal of Biological Markers, 2023
Introduction Complement C5a is an important component of the innate immune system. An increasing number of reports have revealed the relevance of C5a in tumor progression; however, its exact role in metastatic renal cell carcinoma (mRCC) remains unknown.

Persistence of High Levels of Serum Complement C5a in Severe COVID-19 Cases After Hospital Discharge

Frontiers in Immunology, 2021
Evidence supports a role of complement anaphylatoxin C5a in the pathophysiology of COVID-19. However, information about the evolution and impact of C5a levels after hospital discharge is lacking. We analyzed the association between circulating C5a levels

A pro-inflammatory role of C5L2 in C5a-primed neutrophils for ANCA-induced activation. [PDF]

PLoS ONE, 2013
BACKGROUND:The complement system is crucial for the development of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). In particular, C5a and its receptor on neutrophils, CD88, play a central role.

Correlation of serum complement factor 5a level with inflammatory response and cognitive function in patients with Alzheimer’s disease of different severity

BMC Neurology, 2023
Background Alzheimer’s disease (AD) is a common cause of dementia. Serum complement factor 5a (C5a) is exceedingly implicated in AD. We explored the role of C5a levels in AD patients of different severity.

Different concentrations of C5a affect human dental pulp mesenchymal stem cells differentiation

BMC Oral Health, 2021
Background During the process of deep decay, when decay approaches the pulp, an immune response is triggered inside the pulp, which activates the complement cascade.

Local endothelial complement activation reverses endothelial quiescence, enabling t-cell homing, and tumor control during t-cell immunotherapy

OncoImmunology, 2017
Cancer immunotherapy relies upon the ability of T cells to infiltrate tumors. The endothelium constitutes a barrier between the tumor and effector T cells, and the ability to manipulate local vascular permeability could be translated into effective ...

C5a elevation in convalescents from severe COVID-19 is not associated with early complement activation markers C3bBbP or C4d

Frontiers in Immunology, 2022
Numerous publications have underlined the link between complement C5a and the clinical course of COVID-19. We previously reported that levels of C5a remain high in the group of severely ill patients up to 90 days after hospital discharge.
