Complement factors C3a and C5a mimick a proinflammatory microenvironment and increase HBV IGRA sensitivity

Journal of Translational Medicine, 2019
Background Hepatitis B virus (HBV) infections represent a global health problem and chronic hepatitis B (CHB) leads to liver cirrhosis and hepatocellular carcinoma. Thus, timely diagnosis of hepatitis B is crucial to ensure adequate treatment.

Deficiency of high‐molecular‐weight von Willebrand factor mitigates thrombo‐complement injury in an LPS‐induced TMA‐like mouse model

VIEW, EarlyView.
Reduction of high‐molecular‐weight von Willebrand factor disrupts the platelet–complement amplification loop, attenuating microvascular thrombosis, complement deposition, endothelial injury, and organ damage in complement‐mediated thrombotic microangiopathy.

Complement component C5a Promotes Expression of IL-22 and IL-17 from Human T cells and its Implication in Age-related Macular Degeneration

Journal of Translational Medicine, 2011
Background Age related macular degeneration (AMD) is the leading cause of irreversible blindness in elderly populations worldwide. Inflammation, among many factors, has been suggested to play an important role in AMD pathogenesis.

Oral microbiome and homeostatic regulation of periodontal health: From dysbiosis to precision intervention

VIEW, EarlyView.
Periodontal homeostasis is maintained by coordinated interactions between the oral microbiome and host. Dysbiosis disrupts this ecological balance and contributes to periodontal disease, whereas multi‐omics, artificial intelligence, and microbiome‐based interventions provide emerging opportunities for precision diagnosis, ecological restoration, and ...

The role of the complement system and the activation fragment C5a in the central nervous system

, 2010
The complement system is a pivotal component of the innate immune system which protects the host from infection and injury. Complement proteins can be induced in all cell types within the central nervous system (CNS), where the pathway seems to play ...

Evolutionary Mechanisms of Coagulation Factors in Cetaceans During Aquatic Adaptation

Integrative Zoology, EarlyView.
Compared with Bos taurus, T. truncatus showed shorter prothrombin time and thrombin time but prolonged activated partial thromboplastin time, indicating pathway‐specific remodeling of coagulation. Evolutionary analyses identified 18 positively selected genes and accelerated F11 evolution, while functional assays revealed increased coagulation factor ...

Effect of complement C5a in tumor progression and the local tumor microenvironment. [PDF]

, 2011
Monoclonal antibodies directed toward tumor associated antigens are FDA approved anticancer reagents used commonly in the clinic. Administered antibodies initiate tumor cell death through several mechanisms. Improving immune mediated mechanisms, antibody-

Basophils in Immunity: Activation Pathways, Roles in Allergy and AllergoOncology and Application of the Basophil Activation Test

Allergy, EarlyView.
ABSTRACT Basophils, the least abundant leukocytes, are increasingly recognised as potent immunomodulators. Upon activation, they rapidly release preformed granule‐associated mediators including histamine and lipid mediators such as LTC4, while cytokine production occurs over a longer timescale, contributing to downstream immune responses.

Complement proteins changes in ischemic stroke patients and their relation to outcome

Immunobiology
We studied plasma levels of complement system factors C1q, C2, C3, C3b, C4, C4b, C5, C5a, C9 of 84 patients with ischemic stroke within 24 h from onset of symptoms and on seventh day after admission, using Luminex immunoassay.
