Role for Complement C5 in Eosinophilic Inflammation of Severe Asthma

open access: yesAllergy, EarlyView.
Complement activation module, particularly C5, is positively associated with eosinophilic inflammation in severe asthma cohorts. Elevated C5 expression correlates with poor lung function improvement and persistent eosinophilic inflammation. Mouse model studies confirm that C5 exacerbates eosinophilic inflammation, highlighting its potential as a ...

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

open access: yesThe 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.

Absent C3a and C5a receptor signaling into CD4+ T cells enables auto-inductive TGF-β1 signaling and induction of Foxp3+ T regulatory cells

open access: yesNature Immunology, 2012
Signaling through the G protein–coupled receptors for the complement fragments C3a and C5a (C3aR and C5aR, respectively) by dendritic cells and CD4+ cells provides costimulatory and survival signals to effector T cells.

Sequence of Immunological Events During IgE‐Mediated Allergic Reactions to Food

open access: yesAllergy, EarlyView.
ABSTRACT Food allergies (FA) represent a significant global health burden. Upon allergen re‐exposure, allergic patients exhibit a sequence of symptoms that vary in terms of affected organ systems, severity, time of onset and allergen reactivity thresholds.

Signaling through C5a receptor and C3a receptor diminishes function of murine natural regulatory T cells

open access: yesJournal of Experimental Medicine, 2013
Blockade of C3aR/C5aR signaling in nT reg cells augments in vitro and in vivo suppression, abrogates autoimmune colitis, and prolongs allogeneic skin graft survival.

Molecular basis for a pore block of Tentonin 3 expressed in HEK293 cells by a conopeptide, NMB‐1

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Tentonin 3 (TTN3/TMEM150C) is a mechanosensitive ion channel that plays critical roles in mechanotransduction processes. TTN3 forms a tetramer with a predicted rectangular shape and a central pore. A conotoxin ρ‐TIA and its synthetic analog, noxious mechanosensation blocker 1 (NMB‐1), were initially developed to inhibit slowly ...

The tumour microenvironment links complement system dysregulation and hypoxic signalling. [PDF]

open access: yes, 2018
The complement system is an innate immune pathway typically thought of as part of the first line of defence against "non-self" species. In the context of cancer, complement has been described to have an active role in facilitating cancer-associated ...

Bruton tyrosine kinase (Btk) in neutrophils is indispensable for initiating and maintaining skin inflammation in a model of pemphigoid diseases

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Bruton tyrosine kinase (Btk) is essential for B cell function. Its role in myeloid cells is less understood. Greater insights into Btk significance in myeloid cells are needed to evaluate its potential as a therapeutic target during the effector phase of antibody‐induced autoimmune diseases, where inhibiting autoantibody ...

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

open access: yesHeliyon
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.

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

open access: yesEMBO 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 ...
