C3b Catalog Number: A114 Sizes Available
Name: C3b Catalog Number: A114 Sizes Available: 250 µg/vial Concentration: 1.0 mg/mL (see Certificate of Analysis for actual concentration) Form: Liquid Purity: >90% by SDS-PAGE Buffer: 10 mM sodium phosphate, 145 mM NaCl, pH 7.3 Extinction Coeff. A280 nm = 1.03 at 1.0 mg/mL Molecular Weight: 176,000 Da (2 chains) Preservative: None, 0.22 µm filtered Storage: -70oC or below. Avoid freeze/thaw. Source: Normal human serum (shown by certified tests to be negative for HBsAg and for antibodies to HCV, HIV-1 and HIV-II). Precautions: Use normal precautions for handling human blood products. Origin: Manufactured in the USA. General Description C3b is derived from native C3 upon cleavage and release of C3a. It is prepared by cleavage with the alternative pathway C3 convertase. This is important because only a single bond in C3 is cleaved by the native convertase, while cleavage by other proteases, such as trypsin, results in multiple cleavages at many other sites in the protein. Native human C3b is a glycosylated (~2.8%) polypeptide containing two disulfide-linked chains. C3b is central to the function of all three pathways of complement (Law, S.K.A. and Reid, K.B.M. (1995)). Initiation of each pathway generates proteolytic enzyme complexes (C3 convertases) which are bound to the target surface. These enzymes cleave a peptide bond in C3 releasing the anaphylatoxin C3a and activating C3b. For a brief time (~60 µs) this nascent C3b is capable of reacting with and covalently coupling to hydroxyl groups on the target surface. -
Blocking Properdin Prevents Complement-Mediated Hemolytic Uremic Syndrome and Systemic Thrombophilia
BASIC RESEARCH www.jasn.org Blocking Properdin Prevents Complement-Mediated Hemolytic Uremic Syndrome and Systemic Thrombophilia Yoshiyasu Ueda,1 Takashi Miwa,1 Damodar Gullipalli,1 Sayaka Sato,1 Daisuke Ito,1 Hangsoo Kim,1 Matthew Palmer,2 and Wen-Chao Song1 Departments of 1Systems Pharmacology and Translational Therapeutics and 2Pathology and Laboratory Medicine, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania ABSTRACT Background Properdin (P) is a positive regulator of the alternative pathway of complement activation. Although P inhibition is expected and has been shown to ameliorate the alternative pathway of comple- ment-mediated tissue injury in several disease models, it unexpectedly exacerbated renal injury in a murine model of C3 glomerulopathy. The role of P in atypical hemolytic uremic syndrome (aHUS) is uncertain. Methods We blocked P function by genetic deletion or mAb-mediated inhibition in mice carrying a factor H (FH) point mutation, W1206R (FHR/R), that causes aHUS and systemic thrombophilia with high mortality. Results Pdeficiency completely rescued FHR/R mice from premature death and prevented thrombocyto- penia, hemolytic anemia, and renal disease. It also eliminated macrovessel thrombi that were prevalent in FHR/R mice. All mice that received a function-blocking anti-P mAb for 8 weeks survived the experimental period and appeared grossly healthy. Platelet counts and hemoglobin levels were significantly improved in FHR/R mice after 4 weeks of anti-P mAb treatment. One half of the FHR/R mice treated with an isotype control mAb but none of the anti-P mAb-treated mice developed stroke-related neurologic disease. Anti-P mAb-treated FHR/R mice showed largely normal renal histology, and residual liver thrombi were detected in only three of 15 treated mice. -

Neutrophil Chemoattractant Receptors in Health and Disease: Double-Edged Swords
Cellular & Molecular Immunology www.nature.com/cmi REVIEW ARTICLE Neutrophil chemoattractant receptors in health and disease: double-edged swords Mieke Metzemaekers1, Mieke Gouwy1 and Paul Proost 1 Neutrophils are frontline cells of the innate immune system. These effector leukocytes are equipped with intriguing antimicrobial machinery and consequently display high cytotoxic potential. Accurate neutrophil recruitment is essential to combat microbes and to restore homeostasis, for inflammation modulation and resolution, wound healing and tissue repair. After fulfilling the appropriate effector functions, however, dampening neutrophil activation and infiltration is crucial to prevent damage to the host. In humans, chemoattractant molecules can be categorized into four biochemical families, i.e., chemotactic lipids, formyl peptides, complement anaphylatoxins and chemokines. They are critically involved in the tight regulation of neutrophil bone marrow storage and egress and in spatial and temporal neutrophil trafficking between organs. Chemoattractants function by activating dedicated heptahelical G protein-coupled receptors (GPCRs). In addition, emerging evidence suggests an important role for atypical chemoattractant receptors (ACKRs) that do not couple to G proteins in fine-tuning neutrophil migratory and functional responses. The expression levels of chemoattractant receptors are dependent on the level of neutrophil maturation and state of activation, with a pivotal modulatory role for the (inflammatory) environment. Here, we provide an overview -

Abstract The high mortality rate of gastric cancer (GC) is in part due to the absence of initial disclosure of its biomarkers. The recognition of important genes associated in GC is therefore recommended to advance clinical prognosis, diagnosis and and treatment outcomes. The current investigation used the microarray dataset GSE113255 RNA seq data from the Gene Expression Omnibus database to diagnose differentially expressed genes (DEGs). Pathway and gene ontology enrichment analyses were performed, and a proteinprotein interaction network, modules, target genes - miRNA regulatory network and target genes - TF regulatory network were constructed and analyzed. Finally, validation of hub genes was performed. The 1008 DEGs identified consisted of 505 up regulated genes and 503 down regulated genes. -

Although these lipids have numerous effects on diverse cell types and organs, a greater understanding of their specific effects on key players of the immune system has been gained in recent years through the characterization of individual eicosanoid receptors, the identification and development of specific receptor agonists and inhibitors, and the generation of mice genetically deficient in various eicosanoid receptors. -

AML is also characterized with patients with poor long-term survival outcomes due to relapse. Many efforts have been made to understand the biological heterogeneity of AML and the challenges to develop new therapies are therefore enormous. G protein-coupled receptors (GPCRs) are a large attractive drug targeted family of transmembrane proteins, and aberrant GPCR expression and GPCR-mediated signaling have been implicated in leukemogenesis of AML. -
