the overall architecture of Dare-C1qAgD is similar to human C1qA, residues involved in C1qBgD, C1qCgD, and CRP (show CRP Proteins) binding are somewhat different while residues involved in IgG binding are not present in zebrafish. The structure gives insight into how human and fish C1qA evolved from an ancestral protein
C1qA globular domain (C1qAgD) was expressed, purified and crystallized.
We, for the first time, identified the associations between C1q gene SNPs and autoimmune thyroid diseases, and our findings suggested that five common SNPs in C1q gene were not associated with autoimmune thyroid diseases susceptibility in Chinese Han population
exposure of neural stem cells to neutrophil-synthesized concentrations of C1q and C3a (show C3 Proteins) promoted astrogliogenesis and cell migration
this studies show binding of VWF (show VWF Proteins) to C1q and thus a direct interaction between starter molecules of hemostasis and the classical pathway of complement
Cerebrospinal fluid (CSF (show CSF2 Proteins)) soluble complement receptor 2 (sCR2 (show RBMS1 Proteins)) levels correlated significantly both with CSF (show CSF2 Proteins) complements C3 and C1q as well as to a disease severity measure.
This study reveled that C1QA having a central role in the bipolar disease and schizophrenia manifestation.
no significant association found to either rs15940 (C1QA) or rs172378 (C1QC (show C1QC Proteins)) when analysed in just Parkinson disease cases , just controls or combined
Our findings showed that Brugia malayi Calreticulin (show CALR Proteins) (BmCRT) is responsible for the prevention of classical complement pathway activation via its interaction with the first component C1q of the human host
interaction with calreticulin (show CALR Proteins) controls the phagocyte inflammatory status
A newly characterized leech calreticulin (show CALR Proteins) (HmCalR) has been shown to interact with C1q and participate to the HmC1q-dependent microglia accumulation.
findings show that C1q rather than FcgammaRs controls the Ab-mediated Ag uptake and its presentation by spleen APC (show APC Proteins) subsets to T cells
Demonstrate local synthesis of complement proteins by both PDGFRbeta-positive pericytes and CD45 (show PTPRC Proteins)-positive cells in kidney fibrosis.
Deleting C1qa gene significantly reduces synaptic pruning by Grn (show GRN Proteins)(-/-) microglia and mitigates neurodegeneration, behavioral phenotypes, and premature mortality in Grn (show GRN Proteins)(-/-) mice; results uncover a previously unrecognized role of progranulin (show GRN Proteins) in suppressing aberrant microglia activation during aging.
developmental mechanisms of C1qa may be re-engaged during injury response
C1q is involved in the pristane-mediated enhanced inflammatory response to TLR7 (show TLR7 Proteins) stimulation.
Data (including data from studies in mutant mice) suggest exercise prevents age-related neurovascular decline, up-regulation of C1qa, and down-regulation of astrocytic Apoe (show APOE Proteins); this preventive effect of exercise does not occur in Apoe (show APOE Proteins)-deficient mice.
critical role in activation of beta-catenin (show CTNNB1 Proteins) signalling in hypertensive arterial remodelling
Data (including data on knockout mice) suggest, in absence of Trem2 (triggering receptor expressed on myeloid cells 2 (show TREM2 Proteins)), pulmonary macrophages selectively produce elevated levels of C1q resulting in enhanced phagocytosis during pneumococcal pneumonia.
C1q induction and global complement pathway activation do not contribute to ALS toxicity in mutant SOD1 (show SOD1 Proteins) mice.
This gene encodes a major constituent of the human complement subcomponent C1q. C1q associates with C1r and C1s in order to yield the first component of the serum complement system. Deficiency of C1q has been associated with lupus erythematosus and glomerulonephritis. C1q is composed of 18 polypeptide chains: six A-chains, six B-chains, and six C-chains. Each chain contains a collagen-like region located near the N terminus and a C-terminal globular region. The A-, B-, and C-chains are arranged in the order A-C-B on chromosome 1. This gene encodes the A-chain polypeptide of human complement subcomponent C1q.
