In addition to being a component of innate immunity and an ancient defense mechanism against invading pathogens, complement activation also participates in the adaptive immune response, inflammation, hemostasis, embryogenesis, and organ repair and development. Activation of the complement system via classical, lectin, or alternative pathways generates anaphylatoxins (C3a and C5a) and membrane attack complex (C5b-9) and opsonizes targeted cells. Complement activation end products and their receptors mediate cell-cell interactions that regulate several biological functions in the extravascular tissue. Signaling of anaphylatoxin receptors or assembly of membrane attack complex promotes cell dedifferentiation, proliferation, and migration in addition to reducing apoptosis. As a result, complement activation in the tumor microenvironment enhances tumor growth and increases metastasis. In this Review, I discuss immune and nonimmune functions of complement proteins and the tumor-promoting effect of ...

Background/Purpose: The influence of complement-mediated innate immune responses on cartilage and bone homeostasis in the ageing joint have not been studied. Inappropriate complement-mediated cell damage is prevented by membrane regulators such as CD59. Synovial tissue expression of CD59 is altered during inflammatory arthritis; elevated CD59 levels may be necessary to protect joint tissues. Roles of CD59 in maintaining tissue equilibrium and structural architecture within the synovial joint have not been described previously. Since CD59a is the primary regulator of membrane attack complex assembly in mice; we used CD59a-gene-deleted mice (CD59a-/-) as tools to unravel the function of CD59a in modulating age-related joint degeneration. Methods: Hind limbs were collected from C57BL/6J wild type (WT) and CD59a-/- mice at 8-, 20- and 50- weeks of age (6 to 10 mice/group). The Mankin score was used to classify the histopathological severity of osteoarthritic (OA) lesions. Three dimensional ...

Cerebral IR injury produces a profound inflammatory response characterized by neutrophil, macrophage, and platelet accumulation, upregulation of adhesion molecules, blood-brain barrier destruction, and cytokine production.5 During central nervous system inflammation, complement activation plays a direct role in neuronal cell death6 and has been implicated in many disease processes, including subarachnoid hemorrhage,9 Alzheimer disease,10 trauma,11 and stroke.12,13 In a study of patients who died after ischemic stroke, Lindsberg et al9 demonstrated complement deposition within areas of necrosis and concluded that activation of the terminal complement pathway with membrane attack complex assembly occurs within cerebral infarct zones. Others have shown that complement depletion before cerebral IR injury may have neuroprotective effects in animal models.12,14 Huang et al12 used a mouse model of middle cerebral artery occlusion and reperfusion to demonstrate that administering a potent inhibitor of ...
C5a is a protein fragment released from cleavage of complement component C5 by protease C5-convertase into C5a and C5b fragments. C5b is important in late events of the complement cascade, an orderly series of reactions which coordinates several basic defense mechanisms, including formation of the Membrane Attack Complex (MAC), one of the most basic weapons of the innate immune system, formed as an automatic response to intrusions from foreign particles and microbial invaders. It essentially pokes microscopic pinholes in these foreign objects, causing loss of water and sometimes death. C5a, the other cleavage product of C5, acts as a highly inflammatory peptide, encouraging complement activation, formation of the MAC, attraction of innate immune cells, and histamine release involved in allergic responses. The origin of C5 is in the hepatocyte, but its synthesis can also be found in macrophages, where it may cause local increase of C5a. C5a is a chemotactic agent and an anaphylatoxin; it is ...
A 53-kDa protein that is a positive regulator of the alternate pathway of complement activation (COMPLEMENT ACTIVATION PATHWAY, ALTERNATIVE). It stabilizes the ALTERNATIVE PATHWAY C3 CONVERTASE (C3bBb) and protects it from rapid inactivation, thus facilitating the cascade of COMPLEMENT ACTIVATION and the formation of MEMBRANE ATTACK COMPLEX. Individuals with mutation in the PFC gene exhibit properdin deficiency and have a high susceptibility to infections. . ...

c-C3BP or rGAPDH was observed (Figure 3c, d). The H.c-C3BP or rGAPDH interaction with C3 was specific and strong, which was evident from the fact that the column-bound C3 was eluted at high salt wash (0·5 m NaCl) or by lowering the pH to 2·2. To test whether H.c-C3BP or rGAPDH binding to C3 would influence complement function, a simple haemolytic assay was performed where the lysis of sensitized sheep erythrocytes by serum complement proteins was measured. As shown in Figure 3(e, f), a dose-dependent inhibition of erythrocyte lysis by H.c-C3BP and rGAPDH was observed. To rule out that the observed inhibition was not due to suppression of the classical pathway, binding of C1q protein by H.c-C3BP was. measured. No interaction among these proteins was evident in the microtitre plate assay (not shown). To confirm check details whether the inhibition of erythrocyte lysis by H.c-C3BP or rGAPDH was due to suppression of C3 activation, the formation of membrane attack complex (MAC) was measured on the ...
When antigens enter into the body, normally this antigen will be recognized by the antibody that has been generated before during first exposure. The antibody binds to the soluble antigen forming the antibody-antigen complexes in the circulation in order to clear up all of the pathogens. According to Levinson (n.d), the reticuloendothelial system or macrophages system and other phagocytes have the ability to remove the immune antibody-antigen complexes very effectively in a normal condition. However, in type III hypersensitivity, these systems are not capable to remove these complexes. As a result, this antigen-antibody complexes tends to deposit on the wall of the blood vessels. Some of the immune complex deposition on the blood vessel will activate the complement protein such as C1, C4, C3 and C5-9 resulting membrane attack complex, leukocytes chemotaxis, leukocytes polymorphism and phagocytosis as well as inflammation. So that, in classical pathway C1 binds to the antigen-antibody complex and ...
Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease characterised by the production of IgG autoantibodies that are specific for self-antigens, such as DNA, nuclear proteins and certain cytoplasmic components, in association with a diverse array of clinical manifestations. The primary pathological findings in patients with SLE are those of inflammation, vasculitis, immune complex deposition, and vasculopathy. Immune complexes comprising autoantibody and self-antigen is deposited particulary in the renal glomeruli and mediate a systemic inflammatory response by activating complement or via Fc{gamma}R-mediated neutrophil and macrophage activation. Activation of complement (C5) leads to injury both through formation of the membrane attack complex (C5b-9) or by generation of the anaphylatoxin and cell activator C5a. Neutrophils and macrophages cause tissue injury by the release of oxidants and proteases ...

The complement system (Chap. 308) consists of a group of serum proteins functioning as a cooperative, self-regulating cascade of enzymes that adhere to- and in some cases disrupt-the surface of invading organisms. Some of these surface-adherent proteins (e.g., C3b) can then act as opsonins for destruction of microbes by phagocytes. The later, terminal components (C7, C8, and C9) can directly kill some bacterial invaders (notably, many of the neisseriae) by forming a membrane attack complex and disrupting the integrity of the bacterial membrane, thus causing bacteriolysis. ...

I did that trip as a quick turn, assembling a roughly 24-hour itinerary to fly Newark - Montreal - Amsterdam - Newark. I took only my messenger bag with a camera, laptop and a clean t-shirt and underwear. I breezed through the Global Entry kiosks at Newark to the Customs exit where the agent was either suspicious or confused, suggesting to me twice that I go get my bags before presenting myself. And he was none to happy when I smiled and just stood there. I handed over the Global Entry receipt and explained that I was a journalist covering an event and was only gone 24 hours so I had no bags. I made an impression, but not a good one. I was escorted to the secondary screening area at Newarks Terminal C where I did my best to not fall asleep waiting for whatever would come next.. I was not sent into the Green Room which is definitely a good thing. It meant that I got to watch as the agent spent 20 minutes on his computer. Turns out he was looking for questions to ask me about the MD-11 and why ...

Once per month (I think at the beginning of the month, but maybe every 30-ish days?) OS X will verify the contents of any networked backups. That is the point where youll discover whether or not youve been bitten. You can also verify a backup manually by holding down the option key when you access the timemachine menu from the toolbar and choosing Verify Backup. The problem seems to be related to backups that dont run to completion. I see it frequently on my laptop and I believe that it happens when I wake the laptop up, which often fires off a time machine backup, then close it and take it to work with me. I do not believe I have had a problem with a Mac Pro that never leaves its home next to my desk. It is not a FreeNAS issue, it is yet another downside of OS Xs crappy filesystem. Apparently there is a lot of magical code in OS X and the Apple TimeCapsule that makes the remote back more reliable but even there this problem comes up. I also see it on remote disks served up from an ...
TY - JOUR. T1 - Quantitation of activation of the human terminal complement pathway by ELISA. AU - Sanders, Martin E.. AU - Schmetz, Mark A.. AU - Hammer, Carl H.. AU - Frank, Michael M.. AU - Joiner, Keith A.. PY - 1985/12/27. Y1 - 1985/12/27. N2 - We have devised an enzyme-linked immunosorbent assay (ELISA) to quantitate fluid phase terminal complement pathway activation. Upon activation to form C5b-9, terminal complement components express neoantigens not present in the unassembled individual components. Expression of one of these neoantigens occurs at the step of C9 activation. C9 neoantigen is present in fluid phase SC5b-9 complexes, membrane-bound MC5b-9 complexes, and in vitro polymerized C9. Under physiologic conditions, the presence of C9 neoantigen indicates that the terminal complement pathway is activated through the terminal component C9. In our assay for C9 neoantigen, we used rabbit antiserum to polymerized C9 rendered specific for C9 neoantigen c determinants by serial absorption ...
Background: Multiple sclerosis (MS) can be difficult to differentiate from other demyelinating diseases, notably neuromyelitis optica spectrum disorder (NMOSD). We previously showed that NMOSD is distinguished from MS by plasma complement biomarkers. Objective: Here, we measure cerebrospinal fluid (CSF) complement proteins in MS, NMOSD and clinically isolated syndrome (CIS), a neurological episode that may presage MS, to test whether these distinguish NMOSD from MS and CIS. Materials and methods: CSF (53 MS, 17 CIS, 11 NMOSD, 35 controls) was obtained; complement proteins (C4, C3, C5, C9, C1, C1q, Factor B (FB)), regulators (Factor I (FI), Factor H (FH), FH-Related Proteins 1, 2 and 5 (FHR125), C1 Inhibitor (C1INH), Properdin) and activation products (terminal complement complex (TCC), iC3b) were quantified by ELISA and results expressed relative to CSF total protein (μg/mg). Results: Compared to control CSF, (1) levels of C4, C1INH and Properdin were elevated in MS; (2) TCC, iC3b, FI and ...
The presence of lytic antibodies in the circulation of patients with chronic Chagas disease might lead to their cure. It has been shown that amastigotes of Trypanosoma cruzi activate complement and accumulate large amounts of the terminal complement components, but without killing the parasites. One plausible explanation for this observation is that the insertion of the membrane attack complex of complement is prevented by inhibitors present in the parasite membrane. To explore this possibility, we raised a panel of monoclonal antibodies (MAbs) against the surface molecules of T. cruzi amastigotes. One of these, MAb M4C12, induced complement-mediated lysis of amastigotes as detected with a 86Rb-release assay. The antigen molecule from the membrane lysate of amastigotes that was recognized by MAb M4C12 was purified, characterized, and designated M4C12Ag. It is a 92-kD molecule structurally related to Ssp4, a previously characterized amastigote surface molecule. However, M4C12Ag is more basic (pI 6.9-7.1
Background: C reactive protein (CRP), an important serum marker of atherosclerotic vascular disease, has recently been reported to be active inside human atherosclerotic plaques.. Aims: To investigate the simultaneous presence of macrophages, CRP, membrane attack complex C5b-9 (MAC), and oxidised low density lipoprotein (oxLDL) in atherectomy specimens from patients with different coronary syndromes.. Methods: In total, 54 patients with stable angina (SA; n = 21), unstable angina (UA; n = 15), and myocardial infarction (MI; n = 18) underwent directional coronary atherectomy for coronary lesions. Cryostat sections of atherosclerotic plaques were immunohistochemically stained with monoclonal antibodies: anti-CD68 (macrophages), anti-5G4 (CRP), aE11 (MAC), and 12E7 (oxLDL). Immunopositive areas were evaluated in relation to fibrous and neointima tissues, atheroma, and media. Quantitative analysis was performed using image cytometry with systematic random sampling (percentage immunopositive/total ...
The key event in complement activation is the proteolytic cleavage of C3 to C3a and C3b. Three pathways can lead to C3 cleavage, namely, classical, alternative, and mannose-binding lectin (MBL) pathways. C3 cleavage leads on to the activation of the terminal complement pathway, causing the generation of the membrane attack complex (MAC), which assembles…
Better understanding of roles of complement in pathology has fuelled an explosion of interest in complement-targeted therapeutics. The C5-blocking monoclonal antibody (mAb) eculizumab, the first of the new wave of complement blocking drugs, was FDA approved for treatment of Paroxysmal Nocturnal Hemoglobinuria in 2007; its expansion into other diseases has been slow and remains restricted to rare and ultra-rare diseases such as atypical hemolytic uremic syndrome. The success of eculizumab has provoked other Pharma to follow this well-trodden track and made C5 blockade the busiest area of complement drug development. C5 blockade inhibits generation of C5a and C5b, the former an anaphylatoxin, the latter the nidus for formation of the pro-inflammatory membrane attack complex. In order to use anti-complement drugs in common complement-driven diseases, more affordable and equally effective therapeutics are needed. To address this, we explored complement inhibition downstream of C5. Novel blocking ...
TY - JOUR. T1 - Interaction of complement and clusterin in renal injury. AU - Correa-Rotter, Ricardo. AU - Hostetter, Thomas H.. AU - Nath, Karl A. AU - Manivel, J. Carlos. AU - Rosenberg, Mark E.. PY - 1992/11. Y1 - 1992/11. N2 - Clusterin is a heterodimeric glycoprotein that has been associated with such diverse biologic functions as reproduction, cell regression, cell aggregation, and regulation of the cytolytic activity of the membrane attack complex of complement. Clusterin is a component of glomerular immune deposits in the kidney, and increased Clusterin expression occurs in a number of renal injury states. To further explore the interaction between Clusterin and complement, the requirement for an intact complement system for renal Clusterin induction in an acute (folic acid nephropathy) and a chronic (subtotal renal ablation) model of renal injury was examined. After it was first demonstrated that folic acid increased renal clusterin mRNA in the rat, a species in which renal clusterin ...
Nineteen years after Gasser et al. [1] reported HUS, an interesting report was published in the Lancet [10]. This report indicated that although C3-predominant activity is initiated in the blood vessels in TMA patients, this is not observed in typical cases of HUS, suggesting that complement activation is involved in aHUS onset [12]. Subsequently, numerous researchers have elucidated further information on the pathology of aHUS. At present, the reported causes of aHUS include, complement regulation abnormalities, cobalamin metabolism disorder, infection with Streptococcus pneumoniae and other microorganisms, drugs, pregnancy, and autoimmune diseases.. The complement system plays an important role as part of the immune systems of living organisms. It is activated via 3 pathways, the classical, alternative, and lectin pathways. As a result of the activation of the hosts alternative and classical pathways, C5b-9, a membrane attack complex, is generated and destroys cells by forming transmembrane ...
This gene encodes a plasma glycoprotein that positively regulates the alternative complement pathway of the innate immune system. This protein binds to many microbial surfaces and apoptotic cells and stabilizes the C3- and C5-convertase enzyme complexes in a feedback loop that ultimately leads to formation of the membrane attack complex and lysis of the target cell. Mutations in this gene result in two forms of properdin deficiency, which results in high susceptibility to meningococcal infections. Multiple alternatively spliced variants, encoding the same protein, have been identified.[provided by RefSeq, Feb 2009 ...

Dr Noris with Len Woodward of the aHUS alliance at the Research Centre in Bergamo during the whistle top tour of European aHUS Expert Centres ( read here). The alliance registered to attend the webinar. Starting on time the talk proved to be an advanced and up to date learning opportunity about aHUS and the alternative pathway of Complement.. Beginning with describing Thrombotic Microangiopathies (TMAs) , of which aHUS is the one caused by dysregulation of the Complement System. aHUS has an incidence of 0.5 to 2 per million of the population ( which means between 4000 and 15000 new cases globally annually) and without treatment 80% of those patients would die or go into chronic kidney failure.. Marina introduced the components of the pathways of Complement focusing on the Alternative path and the creation of the C5 converteses which sets off the Membrane Attack Complex from a state of continuous tickover. Then spent time explaining the controls, in particular CFH and how in three ways its ...
40 minutes at Newark for a Domestic -> International connection is plenty of time, presuming that your inbound flight is on time, and youre within the same terminal.. Flights from Orlando will almost always arrive in the C terminal, and flights to London will (almost?) always leave from terminal C - so youre covered there.. As for on-time - who can say? There are websites that will give you historic information, but history isnt going to control whether your specific flight is on-time or not.. So all up, the odds of you making the connection are good. Not excellent (if your inbound is more than 10-20 minutes late your odds drop significantly), but still good.. So what happens if you miss the flight?. Newark is a very major United hub. They run multiple flights to London from there every day - especially in the evenings when flights depart as frequently as 1-2 hours apart! Depending on the day, there will likely be 2 other direct flights to London after yours - and the airline will happily ...
Nedd4-family E3 ubiquitin ligases regulate signaling in intracellular pathways that control cancer, blood pressure, iron metabolism, and inflammation. These E3 ligases are catalytically active, and share a highly conserved, modular architecture. How Nedd4 family members are differentially regulated, despite their high degree of homology, is unclear. A regulatory mechanism that maintains an inactive state, common to Nedd4 family members, is autoinhibition. The majority of Nedd4 family members are autoinhibited by an intramolecular interaction between the N terminal C2 domain and the HECT domain. One subfamily of Nedd4 family members that includes the E3 ligase Itch does not appear to be regulated by a C2 domain interaction. The molecular mechanism regulating activation of these E3 ligases is unclear. Here I present findings that illustrate a novel intramolecular interaction regulating Itch and related Nedd4 family member activation that distinguish these E3s as functionally distinct from other Nedd4
So they appeal to the canonical form of context-sensitive grammar rules: αAβ → αγβ, implying that whole grammar is context-sensitive. What Im confused about is rule #3, which seems to be not fitting scheme αAβ → αγβ. I consider terminal $c$ here as part of $\alpha$, variable $B$ as $A$ in scheme, $\beta$ is empty. This implies that $cB$ can not produce $WB$, as $c$ should be saved on same place ($cB\rightarrow c\dots$).. Did I missed something or this grammar was really placed here mistakenly (as it is not real context-sensitive)?. ...

Concerns that the immune system is a two-edged sword that sometimes inhibits and sometimes enhances tumor growth have focused on both the B-cell and T-cell arms of the immune system for over 40 years. While the clinical value of adoptively transfused T cells in a variety of clinical settings is well established (28), recent concerns have focused on regulatory mechanisms able to diminish the antitumor T-cell response and even enhance tumor growth (29). Antibodies and the B-cell response have long been associated with this dichotomy as well (30). Since FDA approval of mAbs such as Rituxan and Herceptin, and their widespread use, there is no doubt about the clinical value of immune effector mechanisms such as complement activation and antibody-dependant cellular cytotoxicity (ADCC), which these antibodies are known to mediate (8, 31). Despite the obvious value of adoptively administered antibodies and T cells, the role of vaccine-induced antibodies and T cells targeting cancer antigens remains less ...
IgG antibody accounts for the vast majority of all antibody mediated protection even though it is the slowest to be produced after the initial insult. Its primary means of protection is to identify the pathogen by attaching to it and marking it for destruction by other immune cells. It can also burst cells by fixing complement. Complement is a group of proteins that build on one another after the initial component has been fixed, much like the first domino must be tipped over to topple the whole row. Once the row has been completed, the complement has the ability to pierce the cell wall of the antigen. Typically only gram negative bacteria can be pierced (lysed) by a particular chain of complement known as the membrane attack (MAC). Gram positives can fall prey to the complement cascade but through the identification route ...
