Anaphylatoxin C3a receptors in asthma [PDF]

Respiratory Research, 2005
AbstractThe complement system forms the central core of innate immunity but also mediates a variety of inflammatory responses. Anaphylatoxin C3a, which is generated as a byproduct of complement activation, has long been known to activate mast cells, basophils and eosinophils and to cause smooth muscle contraction.

Complement Gene Variants Define the Conformational Dynamics of C3 Convertase

European Journal of Immunology, Volume 56, Issue 7, July 2026.
Multidisciplinary data have significantly advanced our understanding of C3bBb molecular dynamics. This review specifically contextualizes the functional impact of disease‐associated genetic variants, demonstrating that clinical genetics not only supports the current C3bBb model but also provides novel insights into previously undefined molecular ...

Efficacy of high‐frequency low‐dose rituximab and acalabrutinib in chronic lymphocytic leukemia

HemaSphere, Volume 10, Issue 7, July 2026.
Abstract Anti‐CD20 monoclonal antibodies (mAbs) are effective but not curative treatment for chronic lymphocytic leukemia (CLL). To study rituximab efficacy, we examined serial blood samples from CLL patients receiving initial monotherapy with high‐frequency low‐dose (HFLD) rituximab for 1 week followed by the addition of acalabrutinib.

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.

Aluminum hydroxide adjuvant differentially activates the three complement pathways with major involvement of the alternative pathway. [PDF]

PLoS ONE, 2013
Al(OH)3 is the most common adjuvant in human vaccines, but its mode of action remains poorly understood. Complement involvement in the adjuvant properties of Al(OH)3 has been suggested in several reports together with a depot effect. It is here confirmed

Ischemia–Reperfusion Injury: Molecular Mechanisms and Therapeutic Interventions

MedComm, Volume 7, Issue 7, July 2026.
Multiorgan ischemia–reperfusion injury begins with ischemia‐induced ATP depletion and ionic imbalance, followed by reperfusion‐triggered mitochondrial ROS/RNS bursts, regulated cell death, and DAMP release. Sterile inflammation converges on endothelial–immune–coagulation crosstalk, where NETs drive immunothrombosis, no‐reflow, and remote organ injury ...

Venom from Bothrops lanceolatus, a Snake Species Native to Martinique, Potently Activates the Complement System

Journal of Immunology Research, 2018
Bothrops lanceolatus snake venom causes systemic thrombotic syndrome but also local inflammation involving extensive oedema, pain, and haemorrhage. Systemic thrombotic syndrome may lead to fatal pulmonary embolism and myocardial and cerebral infarction ...

Proteomic and Transcriptomic Signatures of Poor Asthma Symptom Control in the U‐BIOPRED Cohort

Allergy, Volume 81, Issue 7, Page 2366-2380, July 2026.
No stable features were identified as associated with asthma symptom control in transcriptomics or sputum proteomics. Higher TWEAKR/TNFRSF12A and MBL/MBP‐C serum levels increased the odds of uncontrolled symptoms, while higher MK08/MAPK8 and CD5L serum levels decreased the odds, after adjustment for clinical variables.

Effect of complement 3/5 knockout on renal proteomics landscape after ischemia and reperfusion injury in rats

Physiological Reports, Volume 14, Issue 14, July 2026.
Comparative proteomic analysis of kidneys from C3‐/‐ and C5‐/‐ rats following ischemia‐reperfusion injury (IRI) reveals diverse range of renal injury and repair mechanisms. C3 knockout enhanced mitochondrial, metabolic, and purine pathways while suppressing immune and extracellular matrix programs. In contrast, C5 absences affected extracellular matrix

THE NATURE OF ANAPHYLATOXIN [PDF]

Journal of Experimental Medicine, 1915
1. The union of fresh serum of pregnant or immunized animals with the corresponding boiled protein (substratum) is accompanied by the formation of poisonous substances. 2. The poison originates from the serum as a result of its autodigestion, and not from the substratum. 3. The process of autodigestion may be determined by
