Two New Kindreds with Complete Factor D Deficiency

European Journal of Immunology, Volume 55, Issue 3, March 2025.
The complement system plays a crucial role in immune defense, and factor D deficiency is a rare immunodeficiency associated with life‐threatening bacterial infections. We report two new cases of complete factor D deficiency, including the first described in a Down syndrome patient, highlighting the need to investigate complement deficiencies in ...

Complement activation in Hidradenitis suppurativa: Covert low-grade inflammation or innocent bystander?

Frontiers in Immunology, 2022
Hidradenitis suppurativa (HS) is a chronic auto-inflammatory skin disease with a complex and multifactorial pathogenesis involving both the innate and adaptive immune system.

Methods for detecting, building, and improving tryptophan mannosylation in glycoprotein structures

Protein Science, Volume 34, Issue 2, February 2025.
Abstract Tryptophan mannosylation, the covalent addition of an α‐ᴅ‐mannose sugar to a tryptophan side chain, is a post‐translational modification (PTM) that can affect protein stability, folding, and interactions. Compared to other forms of protein glycosylation, it is relatively uncommon but is affected by conformational anomalies and modeling errors ...

Characterization of the bispecific VHH antibody tarperprumig (ALXN1820) specific for properdin and designed for low-volume administration. [PDF]

MAbs
The bispecific antibody tarperprumig (ALXN1820) was developed as a treatment option for diseases involving dysregulated complement alternative pathway (AP) activity that could be administered in small volumes, either subcutaneously or intravenously ...

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

, 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 ...

Human Properdin Opsonizes Nanoparticles and Triggers a Potent Pro-inflammatory Response by Macrophages without Involving Complement Activation

Frontiers in Immunology, 2018
Development of nanoparticles as tissue-specific drug delivery platforms can be considerably influenced by the complement system because of their inherent pro-inflammatory and tumorigenic consequences.

Synovial Complement Factors in Patients with Periprosthetic Joint Infection after Undergoing Revision Arthroplasty of the Hip or Knee Joint

Diagnostics, 2021
The role and diagnostic value of the synovial complement system in patients with low-grade periprosthetic joint infection (PJI) are unclear. We sought to evaluate, for the first time, the usefulness of synovial complement factors in these patients by ...

A molecular concept of the properdin pathway. [PDF]

Proceedings of the National Academy of Sciences, 1976
The sequential events of the properdin system were analyzed. Properdin-depleted serum allows the formation of a Factor B- and D-dependent C3 convertase. This enzyme, called the properdin-receptor-forming enzyme, was shown to utilize a novel serum component, the initiating factor.

Complement‐targeted therapeutics: Are we there yet, or just getting started?

European Journal of Immunology, Volume 54, Issue 12, December 2024.
After a hesitant start, the number of available therapeutics that target the human complement system has surged from one to a dozen drugs in less than 20 years. Meanwhile, the clinical arsenal encompasses treatment modalities directed to several targets for the therapy of a steadily growing spectrum of complement‐related disorders. Abstract Therapeutic

Modulation of porcine intestinal epitheliocytes immunetranscriptome response by Lactobacillus jensenii TL2937 [PDF]

, 2016
In order to evaluate probiotic strains applicable for the beneficial immunomodulation of the porcine gut (immunobiotics), we previously developed a porcine intestinal epitheliocyte cell line (PIE cells).
