Rat C‐reactive protein activates the autologous complement system

Immunology, 2003
SummaryActivation of complement is a biological function of human C‐reactive protein (hCRP), whereas rat CRP (rCRP) has been claimed to be unable to activate complement. As important biological functions of proteins are probably conserved among species, we re‐evaluated, using various ligands, the capability of rCRP to activate complement.

Interactions of C-reactive protein with the complement system. III. Complement-dependent passive hemolysis initiated by CRP. [PDF]

The Journal of experimental medicine, 1975
Interactions of CRP with various substrates in the presence of human serum have been shown to result in efficient activation of C components C1-C5. We now report the ability of CRP to initiate C-dependent hemolysis. For this purpose CRP was isolated by affinity chromatography using pneumococcal CPS and gel filtration; its purity was established by ...

Tah1 helix-swap dimerization prevents mixed Hsp90 co-chaperone complexes [PDF]

, 2015
Specific co-chaperone adaptors facilitate the recruitment of client proteins to the Hsp90 system. Tah1 binds the C-terminal conserved MEEVD motif of Hsp90, thus linking an eclectic set of client proteins to the R2TP complex for their assembly and ...

Biosynthetic homeostasis and resilience of the complement system in health and infectious diseaseResearch in context

EBioMedicine, 2019
Background: The complement system is a central component of the innate immune system. Constitutive biosynthesis of complement proteins is essential for homeostasis.

Complementing antibody profiles: Assessing antibody function on antigen microarrays [PDF]

, 2012
Antibody effector functions other than neutralization depend on interactions with soluble and cellular components of the immune system. Antigen recognition is usually oligoclonal, with the different clones of antibodies belonging to different ...

Innate immune system activation in zebrafish and cellular models of Diamond Blackfan Anemia. [PDF]

, 2018
Deficiency of ribosomal proteins (RPs) leads to Diamond Blackfan Anemia (DBA) associated with anemia, congenital defects, and cancer. While p53 activation is responsible for many features of DBA, the role of immune system is less defined.

COMPLEMENT SYSTEM PROTEIN C4 AND SUSCEPTIBILITY TO HYDRALAZINE-INDUCED SYSTEMIC LUPUS ERYTHEMATOSUS

The Lancet, 1989
21 patients with systemic lupus erythematosus induced by long-term treatment with hydralazine were investigated to see whether susceptibility to this syndrome was associated with deficiency of the classical pathway complement protein, C4. 16 of 21 (76%) patients had one or more C4 null (ie, non-productive) alleles compared with 35 of 82 normal subjects

Synovial fibroblast‐like cells synthesize seven proteins of the complement system [PDF]

Arthritis & Rheumatism, 1988
AbstractFibroblast‐like cells from synovial tissue obtained during arthroscopy in 4 young adults with recent knee trauma were biosynthetically labeled with 35S‐methionine, and protein production was quantitated by immunoprecipitation and sodium dodecyl sulfate—polyacrylamide gel electrophoresis.

Factor H Family Proteins in Complement Evasion of Microorganisms

Frontiers in Immunology, 2017
Human-pathogenic microbes possess various means to avoid destruction by our immune system. These include interactions with the host complement system that may facilitate pathogen entry into cells and tissues, expression of molecules that defuse the ...

Hijacking Complement Regulatory Proteins for Bacterial Immune Evasion

Frontiers in Microbiology, 2016
The human complement system plays an important role in the defense against invading pathogens, inflammation and homeostasis. Invading microbes, such as bacteria, directly activate the complement system resulting in the formation of chemoattractants and ...
