Overactivity of Alternative Pathway Convertases in Patients With Complement-Mediated Renal Diseases

Frontiers in Immunology, 2018
Overactivation of the alternative pathway of the complement system is associated with the renal diseases atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathy (C3G).

Alternative final steps in berberine biosynthesis in Coptis japonica cell cultures [PDF]

, 1988
In Coptis japonica cell cultures an alternative pathway has been discovered which leads from (S)-tetrahydrocolumbamine via (S)-canadine to berberine. The two enzymes involved have been partially purified.

Hijacking Factor H for Complement Immune Evasion

Frontiers in Immunology, 2021
The complement system is an essential player in innate and adaptive immunity. It consists of three pathways (alternative, classical, and lectin) that initiate either spontaneously (alternative) or in response to danger (all pathways). Complement leads to

Serine biosynthesis with one carbon catabolism represents a novel pathway for ATP generation in cells using alternative glycolysis with zero net ATP production [PDF]

, 2011
Recent experimental evidence indicates that some cancer cells have an alternative glycolysis pathway with net zero ATP production, implying that upregulation of glycolysis in these cells may not be related to the generation of ATP.

Functional evaluation of rare variants in complement factor I using a minigene assay

Frontiers in Immunology
The regulatory serine protease, complement factor I (FI), in conjunction with one of its cofactors (FH, C4BP, MCP, or CR1), plays an essential role in controlling complement activity through inactivation of C3b and C4b.

Hospitalization Through Families’ Eyes: Comparing Inpatient Care Quality for Children With Sickle Cell Disease and Cystic Fibrosis in Canada

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

A TRAF3-NIK module differentially regulates DNA vs RNA pathways in innate immune signaling. [PDF]

, 2018
Detection of viral genomes by the innate immune system elicits an antiviral gene program mediated by type I interferons (IFNs). While viral RNA and DNA species induce IFN via separate pathways, the mechanisms by which these pathways are differentially ...

Factor H-related protein 1 in systemic lupus erythematosus

Frontiers in Immunology
BackgroundFactor H (FH) is a major soluble inhibitor of the complement system and part of a family comprising five related proteins (FHRs 1–5). Deficiency of FHR1 was described to be linked to an elevated risk of systemic lupus erythematosus (SLE).

Alternative pathway dysregulation and the conundrum of complement activation by IgG4 immune complexes in membranous nephropathy

Frontiers in Immunology, 2016
Membranous nephropathy (MN), a major cause of nephrotic syndrome, is a non-inflammatory immune kidney disease mediated by IgG antibodies that form glomerular subepithelial immune complexes.
