Invasive Meningococcal Disease in a Patient With Complement 7 Deficiency

open access: yesJournal of General and Family Medicine, Volume 26, Issue 6, Page 646-649, November 2025.
ABSTRACT Neisseria meningitidis can cause invasive meningococcal disease (IMD). Individuals with primary complement deficiencies are at a higher risk of developing IMD. However, cases of IMD associated with complement deficiency have rarely been reported in Japan.

Hybrid mass spectrometry approaches in glycoprotein analysis and their usage in scoring biosimilarity

open access: yesNature Communications, 2016
Many biopharmaceuticals exhibit mixed heterogeneity in their post-translational modifications (PTMs) that are essential for their function. Here the authors use a combination of mass spectrometry techniques to analyse human erythropoietin (EPO) and ...

Widely Used Commercial ELISA Does Not Detect Precursor of Haptoglobin2, but Recognizes Properdin as a Potential Second Member of the Zonulin Family

open access: yesFrontiers in Endocrinology, 2018
BackgroundThere is increasing evidence for the role of impaired intestinal permeability in obesity and associated metabolic diseases. Zonulin is an established serum marker for intestinal permeability and identical to pre-haptoglobin2.

Immunoglobulin A Nephropathy: Molecular Pathogenesis and Targeted Therapy

open access: yesMedComm, Volume 6, Issue 9, September 2025.
The future of IgAN treatment likely involves combining several therapies to target multiple disease mechanisms simultaneously. Clinical trials are ongoing to evaluate the efficacy and safety of various combinations. As our understanding of IgAN pathogenesis evolves, more targeted and personalized treatment strategies are expected to emerge.

Short‐Term Severe Energy Restriction Promotes Molecular Health and Reverses Aging Signatures in Adults With Prediabetes in the PREVIEW Study

open access: yesAging Cell, Volume 24, Issue 8, August 2025.
Severe short‐term energy restriction in adults with prediabetes led to a significant reduction in circulating proteins linked to inflammation, senescence, and protein turnover. These changes, partly mediated by extracellular vesicles, suggest systemic dietary‐induced benefits beyond glycemic control, including improved aging biomarkers.

Study of the variables associated with local complement activation in IgA nephropathy

open access: yesNefrología (English Edition), 2017
Objectives: 1. To identify the variables that are associated with urinary levels of properdin, MBL, C4d, and C5b-9 in patients with idiopathic IgA nephropathy. 2. To analyse whether urinary levels of MBL and/or C4d are useful for identifying the presence

Biotic and abiotic factors of bactericidal properties variability of ruminant saliva

open access: yesBIO Web of Conferences, 2020
The microflora of the oral cavity of domestic ruminants, presented by transitive gram-negative species of bacteria (cocci and sticks) in cows, transient and obligate gram-positive (usually cocci) bacteria in sheep was studied. The lowest contamination of

Carrier detection by microsatellite haplotyping in 10 properdin type 1-deficient families [PDF]

open access: yes, 1996
Properdin deficiency carrier identification is relevant, because properdin-deficient persons have an increased risk of contracting meningococcal disease. Vaccination against meningococcal disease at a young age may provide protection.

Studies on relationship between serum properdin and cancer III. Influence of anticancer agents on the serum properdin level [PDF]

open access: yes, 1961
1. When the various anticancer agents are injected intravenously to normal rabbits and intraperitoneally to normal mice, it seems that the serum properdin levels fall transitorily for some hours after administration with a small dose and then keep rising,

Monomeric C-reactive protein inhibits renal cell-directed complement activation mediated by properdin. [PDF]

open access: yes, 2016
Previous studies have shown that complement activation on renal tubular cells is involved in the induction of interstitial fibrosis and cellular injury.
