Complement C4A Regulates Autoreactive B Cells in Murine Lupus [PDF]
Summary: Systemic lupus erythematosus (SLE) is a severe autoimmune disease mediated by pathogenic autoantibodies. While complement protein C4 is associated with SLE, its isoforms (C4A and C4B) are not equal in their impact.

Clinical features of patients with homozygous complement C4A or C4B deficiency. [PDF]
IntroductionHomozygous deficiencies of complement C4A or C4B are detected in 1-10% of populations. In genome-wide association studies C4 deficiencies are missed because the genetic variation of C4 is complex.

Copy number analysis of complement C4A, C4B and C4A silencing mutation by real-time quantitative polymerase chain reaction. [PDF]
Low protein levels and copy number variation (CNV) of the fourth component of human complement (C4A and C4B) have been associated with various diseases. High-throughput methods for analysing C4 CNV are available, but they commonly do not detect the most ...

Real-time PCR quantification of human complement C4A and C4B genes [PDF]
Background The fourth component of human complement (C4), an essential factor of the innate immunity, is represented as two isoforms (C4A and C4B) in the genome.

Hepatic steatosis in postmenopausal women is characterized by distinct serum extracellular vesicle proteomic signatures [PDF]
Background Metabolic dysfunction-associated steatotic liver disease (MASLD) is common among midlife women. Circulating extracellular vesicles (EVs) carry bioactive cargo that may mediate or reflect disease processes, but their role in hepatic steatosis ...

There was an error in the Competing Interests statement. The correct Competing interests are: MLL is working as a consultant at a company owned by the University of Helsinki providing complement C4 analysis for diagnostic samples. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials. The other authors
