Legionella pneumophila lipopolysaccharide activates the classical complement pathway [PDF]
Legionella pneumophila is a gram-negative bacterium capable of entering and growing in alveolar macrophages and monocytes. Complement and complement receptors are important in the uptake of L. pneumophila by human mononuclear phagocytes. The surface molecules of L. pneumophila that activate the complement system are unknown.

The role of complement in Streptococcus pneumoniae-associated haemolytic uraemic syndrome [PDF]
Background. Atypical forms of haemolytic uraemic syndrome (aHUS) include HUS caused by defects in the regulation of alternative complement pathway and HUS linked to neuraminidase- producing pathogens, such as Streptococcus pneumoniae. Increasing data

A Computational and Experimental Study of the Regulatory Mechanisms of the Complement System [PDF]
The complement system is key to innate immunity and its activation is necessary for the clearance of bacteria and apoptotic cells. However, insufficient or excessive complement activation will lead to immune-related diseases. It is so far unknown how the

ABSTRACT Objective SCN1A‐related seizures first present as febrile seizures (FS). Definitive features emerge later, making early diagnosis challenging. We evaluated the diagnostic yield and clinical characteristics of pathogenic SCN1A variants in FS, and analyzed the effect of variant characteristics on clinical phenotypes required for early ...

Preanalytical classical and alternative complement pathway activity loss
Introduction: Complement functional analyses provide insight into the integrity of the entire complement reaction cascade. These tests are suitable for investigating suspected complement deficiencies. Falsely reduced test outcomes may result from preanalytical instabilities of individual complement components.

Stability of C3 Convertase in the Rat Classical Complement Pathway [PDF]
AbstractIt has been reported that rat serum complement causes efficient hemolysis of antibody‐sensitized sheep erythrocytes (EA) at 20 C but not at 37 C. In connection with this, we demonstrated that C3 convertase of rat complement was significantly unstable at 37 C using purified components of rat complement.

Efgartigimod Combined With Steroid Treatment for HAM/TSP: A Case Report
ABSTRACT HTLV‐1‐associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a progressive neurological disorder with limited treatment options. We report a 54‐year‐old female with decade‐long, progressive HAM/TSP, previously refractory to rituximab, who experienced worsening spastic paraparesis and neurogenic bladder dysfunction.

Objectives Cognitive impairment (CI) is common in patients with Systemic Lupus Erythematosus (SLE). Despite its prevalence, the immune mechanisms are not well understood. We previously reported elevated serum levels of S100A8/A9 and MMP‐9 in SLE patients with CI.

Objective A leading cause of death among scleroderma (SSc) patients, interstitial lung disease (ILD) remains challenging to prognosticate. The discovery of biomarkers that accurately determine which patients would benefit from close monitoring and aggressive therapy would be an essential clinical tool.
