Elevated levels of C3, C4, and CH50 of the complement system in ICU and non‐ICU patients with COVID‐19

open access: yesHealth Science Reports, 2022
Purpose SARS‐CoV‐2 infection has spread in each corner of the world. Many health systems have dealt with it intensively. The complement system is an instrumental component in the inflammatory immune response and plays a role in the activation of blood ...

Paths reunited: initiation of the classical and lectin pathways of complement activation [PDF]

open access: yes, 2010
Understanding the structural organisation and mode of action of the initiating complex of the classical pathway of complement activation (C1) has been a central goal in complement biology since its isolation almost 50 years ago.

SALO, a novel classical pathway complement inhibitor from saliva of the sand fly Lutzomyia longipalpis. [PDF]

open access: yes, 2016
Blood-feeding insects inject potent salivary components including complement inhibitors into their host's skin to acquire a blood meal. Sand fly saliva was shown to inhibit the classical pathway of complement; however, the molecular identity of the ...

Altered Complement System Activity in Schizophrenia: Overexpression of C4 and/or Abnormal Expression of Complement Control Proteins in the DLPFC, Parietal Cortex, Temporal Cortex, Associative Striatum, Hippocampus, Cerebellum and Whole Blood

open access: yesEuropean Psychiatry, 2022
Introduction In schizophrenia, abnormal synaptic pruning during adolescence may be due to an altered Complement system activity. While this hypothesis is supported by C4 overexpression in various brain regions of individuals with schizophrenia, such ...

QPTAS and Subexponential Algorithm for Maximum Clique on Disk Graphs [PDF]

open access: yes, 2018
A (unit) disk graph is the intersection graph of closed (unit) disks in the plane. Almost three decades ago, an elegant polynomial-time algorithm was found for Maximum Clique on unit disk graphs [Clark, Colbourn, Johnson; Discrete Mathematics '90]. Since

Structural Model for Factor X Inhibition of IgM and Complement-Mediated Neutralization of Adenovirus

open access: yesViruses, 2023
Adenovirus has strong therapeutic potential as an oncolytic virus and gene therapy vector. However, injecting human species C serotype 5 adenovirus, HAdv-C5, into the bloodstream leads to numerous interactions with plasma proteins that affect viral ...

Genetically predicted complement component 4A expression: effects on memory function and middle temporal lobe activation [PDF]

open access: yes, 2018
Background The longstanding association between the major histocompatibility complex (MHC) locus and schizophrenia (SZ) risk has recently been accounted for, partially, by structural variation at the complement component 4 (C4) gene.

Serum complement levels in immune thrombocytopenia: Characterization and relation to clinical features

open access: yesResearch and Practice in Thrombosis and Haemostasis, 2020
Background Complement may contribute to platelet destruction in immune thrombocytopenia (ITP), but serum complement levels of ITP patients are not well defined. This study characterized C3, C4, and CH50 levels from 108 ITP patients in comparison with 120
