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 ...

C5aR1 signaling triggers lung immunopathology in COVID-19 through neutrophil extracellular traps

The Journal of Clinical Investigation, 2023
Patients with severe COVID-19 develop acute respiratory distress syndrome (ARDS) that may progress to cytokine storm syndrome, organ dysfunction, and death.

Role of C5aR2 in prognosis of patients with acute respiratory distress syndrome through negative modulation of C5a: A prospective observational study

Heliyon
Objective: Diverse inflammatory pathology is involved in acute respiratory distress syndrome (ARDS). This study aimed to assess the role of complement component fragment 5a (C5a) receptor 2 (C5aR2) in prognosis of patients with ARDS.

Expression of complement C5a receptor and the viability of 4T1 tumor cells following agonist–antagonist treatment

, 2016
Background: Complement system is theoretically believed to halt the progression of tumor by the activity of C5a/CD88. Protein C5a is a potent pro.inflammatory mediator that activates the complement system by binding to its receptor.

Experimental design of complement component 5a-induced acute lung injury (C5a-ALI): a role of CC-chemokine receptor type 5 during immune activation by anaphylatoxin [PDF]

, 2015
Excessive activation of the complement system is detrimental in acute inflammatory disorders. In this study, we analyzed the role of complement‐derived anaphylatoxins in the pathogenesis of experimental acute lung injury/acute respiratory distress ...

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.

ANGPTL4 exacerbates pancreatitis by augmenting acinar cell injury through upregulation of C5a

EMBO Molecular Medicine, 2020
Pancreatitis is the inflammation of the pancreas. However, little is known about the genes associated with pancreatitis severity. Our microarray analysis of pancreatic tissues from mild and severe acute pancreatitis mice models identified angiopoietin ...

Discovery of the first selective C5A receptor 2 (C5L2/C5AR2) ligands

, 2016
A method of selectively modulating the activity of C5a receptor 2 (C5aR2). The method includes exposing the receptor to a compound that selectively modulates C5aR2 compared to C5a receptor 1 (C5aR1).

Distinct Gene Expression Profiles of Ara h 2‐Specific B Cells in Desensitization and Tolerance During Peanut Oral Immunotherapy

Allergy, EarlyView.
Gene expression of Ara h 2‐specific B cells over the course of the peanut OIT. Isotype of allergen‐specific B cells changes through OIT towards IgG4. Peanut OIT changes the gene expression of allergen‐specific memory B cells. OIT patients showed increased gene expression for regulatory B cells and immune regulation.
