Our study nding would ultimately provide reliable scientic conclusions to guide clinical practice. Methods PubMed, Embase, The Chorane Library and Google Scholar were systematically searched to identify all studies on serum C3 concentrations in cancer patients published as of September 2019. Additionally, we conducted a clinical study on serum C3 in lung cancer patients and healthy people. The levels of serum complement C3 in 84 lung cancer patients and 30 healthy people were examined by ELISA. We used standardized mean differences (SMD) to report the pooled estimation, and I² statistics were calculated to examine the heterogeneity. -
Complement Peptide C3a Receptor 1 Promotes Optic Nerve Degeneration in DBA/2J Mice Jeffrey M
Harder et al. Journal of Neuroinflammation (2020) 17:336 https://doi.org/10.1186/s12974-020-02011-z RESEARCH Open Access Complement peptide C3a receptor 1 promotes optic nerve degeneration in DBA/2J mice Jeffrey M. Harder1, Pete A. Williams1,2 , Catherine E. Braine1,3, Hongtian S. Yang1, Jocelyn M. Thomas1, Nicole E. Foxworth1, Simon W. M. John1,4,5* and Gareth R. Howell1,6,7* Abstract Background: The risk of glaucoma increases significantly with age and exposure to elevated intraocular pressure, two factors linked with neuroinflammation. The complement cascade is a complex immune process with many bioactive end-products, including mediators of inflammation. Complement cascade activation has been shown in glaucoma patients and models of glaucoma. However, the function of complement-mediated inflammation in glaucoma is largely untested. Here, the complement peptide C3a receptor 1 was genetically disrupted in DBA/2J mice, an ocular hypertensive model of glaucoma, to test its contribution to neurodegeneration. Methods: A null allele of C3ar1 was backcrossed into DBA/2J mice. Development of iris disease, ocular hypertension, optic nerve degeneration, retinal ganglion cell activity, loss of RGCs, and myeloid cell infiltration in C3ar1-deficient and sufficient DBA/2J mice were compared across multiple ages. RNA sequencing was performed on microglia from primary culture to determine global effects of C3ar1 on microglia gene expression. Results: Deficiency in C3ar1 lowered the risk of degeneration in ocular hypertensive mice without affecting intraocular pressure elevation at 10.5 months of age. Differences were found in the percentage of mice affected, but not in individual characteristics of disease progression. -

Important Roles of C5a and C5ar in Tumor Development and Cancer Treatment
E3S Web o f Conferences 136, 06012 (2019) https://doi.org/10.1051/e3sconf/20191360 6012 ICBTE 2019 Important roles of C5a and C5aR in tumor development and cancer treatment Wang Yuxuan Bioengineering, School of Life Science, Anhui University,230601 Abstract: The complement system is part of the body's innate defense immune system, which can identify and eliminate invasive pathogenic microorganisms to maintain normal life activities. Complement Component 5a (C5a) is an active anaphylatoxin produced after complement system activation, closely related to tumor formation. C5a is highly expressed in a variety of tumors, and combines with its Complement Component 5a Receptor (C5aR) to increase the proliferation and migration of tumor cells. This review will comprehensively elaborate the important role of C5a/C5aR in the process of tumor genesis and development from the three aspects of signal transduction pathways related to tumor, C5a/C5aR and tumor formation, and C5a/C5aR inhibitors and tumor therapy. Finally, the principle of complement inhibition is used to inhibit tumor metastasis, reduce the rate of tumor diffusion, and control the trend of tumor deterioration. 1 Introduction The generation of tumor is closely related to the microenvironment in which tumor is located. A variety of cells in the microenvironment, such as lymphocytes, macrophages, fibroblasts and various molecules, such as complement and cytokines, are involved in the survival, proliferation and metastasis of tumor cells. Complement Component is a protein with enzyme activity. Since the discovery of complement system by Belgian doctor J. Bordet in 1890, a large number of studies have shown that complement exists in human serum, tissue fluid and cell membrane surface1. -
Properdin Factor D: Effects on Thrombin-Induced Platelet Aggregation
Properdin factor D: effects on thrombin-induced platelet aggregation. A E Davis 3rd, D M Kenney J Clin Invest. 1979;64(3):721-728. https://doi.org/10.1172/JCI109515. Research Article Factor D, when preincubated with platelet suspensions, at concentrations as low as 1.2 micrograms/ml, inhibited thrombin-induced platelet aggregation. No inhibition of collagen or arachidonic acid-induced platelet aggregation was found. Inhibition occurred, but to a lesser extent, when thrombin and factor D were added to platelets at the same time. No inhibition occurred when factor D was added after thrombin. Thrombin was able to overcome inhibition by factor D by increasing its concentration. Diisopropyl-phosphorofluoridate-inactivated factor D also inhibited thrombin-induced platelet aggregation so that enzymatic activity of factor D was not required for inhibition. Factor D absorbed with hirudin coupled to Sepharose 6B showed no decrease in inhibitory capacity. 125I-Factor D bound to platelets in a manner suggesting an equilibrium reaction similar to thrombin. At low factor D input, binding was linear, whereas at higher input, binding began to approach saturation. Binding of 125I-labeled thrombin to platelets was inhibited by factor D. Analysis of these data show that factor D does not alter the total number of thrombin molecules which bind to the platelet surface at saturation. However, the dissociation constant for thrombin is altered from 2.78 to 6.90 nM in the presence of factor D (20 micrograms/ml). Factor D is thus a competitive inhibitor of thrombin binding, although the affinity of factor D for the platelet thrombin receptor is much less […] Find the latest version: https://jci.me/109515/pdf Properdin Factor D EFFECTS ON THROMBIN-INDUCED PLATELET AGGREGATION ALVIN E. -

Age-related macular degeneration (AMD) is the most common cause of visual loss in developed countries, with a signifcant economic and social burden on public health. Although genome-wide and gene-candidate studies have been enabled to identify genetic variants in the complement system associated with AMD pathogenesis, the efect of gene-environment interaction is still under debate. In this review we provide an overview of the role of complement system and its genetic variants in AMD, summarizing the consequences of the interaction between genetic and environmental risk factors on AMD onset, progression, and therapeutic response. Finally, we discuss the perspectives of current evidence in the feld of genomics driven personalized medicine and public health. -
High-Throughput Proteomic Profiling of the Fish Liver Following Bacterial
Causey et al. BMC Genomics (2018) 19:719 https://doi.org/10.1186/s12864-018-5092-0 RESEARCH ARTICLE Open Access High-throughput proteomic profiling of the fish liver following bacterial infection Dwight R Causey1, Moritz A N Pohl1, David A Stead2, Samuel A M Martin1, Christopher J Secombes1 and Daniel J Macqueen1* Abstract Background: High-throughput proteomics was used to determine the role of the fish liver in defense responses to bacterial infection. This was done using a rainbow trout (Oncorhynchus mykiss) model following infection with Aeromonas salmonicida, the causative agent of furunculosis. The vertebrate liver has multifaceted functions in innate immunity, metabolism, and growth; we hypothesize this tissue serves a dual role in supporting host defense in parallel to metabolic adjustments that promote effectiveimmunefunction.Whilepaststudieshavereported mRNA responses to A. salmonicida in salmonids, the impact of bacterial infection on the liver proteome remains uncharacterized in fish. Results: Rainbow trout were injected with A. salmonicida or PBS (control) and liver extracted 48 h later for analysis on a hybrid quadrupole-Orbitrap mass spectrometer. A label-free method was used for protein abundance profiling, which revealed a strong innate immune response along with evidence to support parallel rewiring of metabolic and growth systems. 3076 proteins were initially identified against all proteins (n = 71,293 RefSeq proteins) annotated in a single high-quality rainbow trout reference genome, of which 2433 were maintained for analysis post-quality filtering. Among the 2433 proteins, 109 showed significant differential abundance following A. salmonicida challenge, including many upregulated complement system and acute phase response proteins, in addition to molecules with putative functions that may support metabolic re-adjustments.
