alpha-2-Antiplasmin: A member of the serpin superfamily found in plasma that inhibits the lysis of fibrin clots which are induced by plasminogen activator. It is a glycoprotein, molecular weight approximately 70,000 that migrates in the alpha 2 region in immunoelectrophoresis. It is the principal plasmin inactivator in blood, rapidly forming a very stable complex with plasmin.Fibrinolysin: A product of the lysis of plasminogen (profibrinolysin) by PLASMINOGEN activators. It is composed of two polypeptide chains, light (B) and heavy (A), with a molecular weight of 75,000. It is the major proteolytic enzyme involved in blood clot retraction or the lysis of fibrin and quickly inactivated by antiplasmins.Fibrinolysis: The natural enzymatic dissolution of FIBRIN.Plasminogen: Precursor of plasmin (FIBRINOLYSIN). It is a single-chain beta-globulin of molecular weight 80-90,000 found mostly in association with fibrinogen in plasma; plasminogen activators change it to fibrinolysin. It is used in wound debriding and has been investigated as a thrombolytic agent.Hemorrhagic Disorders: Spontaneous or near spontaneous bleeding caused by a defect in clotting mechanisms (BLOOD COAGULATION DISORDERS) or another abnormality causing a structural flaw in the blood vessels (HEMOSTATIC DISORDERS).Antifibrinolytic Agents: Agents that prevent fibrinolysis or lysis of a blood clot or thrombus.

Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.Hemostasis: The process which spontaneously arrests the flow of BLOOD from vessels carrying blood under pressure. It is accomplished by contraction of the vessels, adhesion and aggregation of formed blood elements (eg. ERYTHROCYTE AGGREGATION), and the process of BLOOD COAGULATION.Streptokinase: Streptococcal fibrinolysin . An enzyme produced by hemolytic streptococci. It hydrolyzes amide linkages and serves as an activator of plasminogen. It is used in thrombolytic therapy and is used also in mixtures with streptodornase (STREPTODORNASE AND STREPTOKINASE). EC 3.4.-.Urokinase-Type Plasminogen Activator: A proteolytic enzyme that converts PLASMINOGEN to FIBRINOLYSIN where the preferential cleavage is between ARGININE and VALINE. It was isolated originally from human URINE, but is found in most tissues of most VERTEBRATES.Complement C1 Inactivator Proteins: Serum proteins that inhibit, antagonize, or inactivate COMPLEMENT C1 or its subunits.Fibrin Fibrinogen Degradation Products: Soluble protein fragments formed by the proteolytic action of plasmin on fibrin or fibrinogen.

Deficiency of factor XII, also called the Hageman trait, leads to increased incidence of thromboembolic disease. Mutations in the gene for factor XII that appear to increase factor XII amidolytic activity are associated with HEREDITARY ANGIOEDEMA TYPE III.Receptors, Adrenergic, alpha: One of the two major pharmacological subdivisions of adrenergic receptors that were originally defined by the relative potencies of various adrenergic compounds. The alpha receptors were initially described as excitatory receptors that post-junctionally stimulate SMOOTH MUSCLE contraction.

Relationship of plasmin generation to cardiovascular disease risk factors in elderly men and women. (1/266)

Plasmin-alpha2-antiplasmin complex (PAP) marks plasmin generation and fibrinolytic balance. We recently observed that elevated levels of PAP predict acute myocardial infarction in the elderly, yet little is known about the correlates of PAP. We measured PAP in 800 elderly subjects who were free of clinical cardiovascular disease in 2 cohort studies: the Cardiovascular Health Study and the Honolulu Heart Program. Median PAP levels did not differ between the Cardiovascular Health Study (6.05+/-1.46 nmol/L) and the Honolulu Heart Program (6.11+/-1.44 nmol/L), and correlates of PAP were similar in both cohorts. In CHS, PAP levels increased with age (r=0. 30), procoagulant factors (eg, factor VIIc, r=0.15), thrombin activity (prothrombin fragment F1+2, r=0.29), and inflammation-sensitive proteins (eg, fibrinogen, r=0.44; factor VIIIc, r=0.37). PAP was associated with increased atherosclerosis as measured by the ankle-arm index (AAI) (P for trend, +info)

Alpha2-antiplasmin gene deficiency in mice is associated with enhanced fibrinolytic potential without overt bleeding. (2/266)

alpha2-antiplasmin (alpha2-AP) is the main physiologic plasmin inhibitor in mammalian plasma. Inactivation of the murine alpha2-AP gene was achieved by replacing, through homologous recombination in embryonic stem cells, a 7-kb genomic sequence encoding the entire murine protein (exon 2 through part of exon 10, including the stop codon) with the neomycin resistance expression cassette. Germline transmission of the mutated allele was confirmed by Southern blot analysis. Mendelian inheritance of the inactivated alpha2-AP allele was observed, and homozygous deficient (alpha2-AP-/-) mice displayed normal fertility, viability, and development. Reverse transcription-polymerase chain reaction confirmed the absence of alpha2-AP mRNA in kidney and liver from alpha2-AP-/- mice, in contrast to wild-type (alpha2-AP+/+) mice. Immunologic and functional alpha2-AP levels were undetectable in plasma of alpha2-AP-/- mice, and were about half of wild-type in heterozygous littermates (alpha2-AP+/-). Other hemostasis parameters, including plasminogen activator inhibitor-1, plasminogen, fibrinogen, hemoglobin, hematocrit, and blood cell counts were comparable for alpha2-AP+/+, alpha2-AP+/-, and alpha2-AP-/- mice. After amputation of tail or toe tips, bleeding stopped spontaneously in alpha2-AP+/+, as well as in alpha2-AP+/- and alpha2-AP-/- mice. Spontaneous lysis after 4 hours of intravenously injected 125I-fibrin-labeled plasma clots was significantly higher in alpha2-AP-/- than in alpha2-AP+/+ mice when injecting clots prepared from alpha2-AP+/+ plasma (78% +/- 5% v 46% +/- 9%; mean +/- SEM, n = 6 to 7; P =.02) or from alpha2-AP-/- plasma (81% +/- 5% v 46% +/- 5%; mean +/- SEM, n = 5; P =.008). Four to 8 hours after endotoxin injection, fibrin deposition in the kidneys was significantly reduced in alpha2-AP-/- mice, as compared with alpha2-AP+/+ mice (P +info)

Angiostatin inhibits endothelial and melanoma cellular invasion by blocking matrix-enhanced plasminogen activation. (3/266)

Angiostatin, a kringle-containing fragment of plasminogen, is a potent inhibitor of angiogenesis. The mechanism(s) responsible for the anti-angiogenic properties of angiostatin are unknown. We now report that human angiostatin blocks plasmin(ogen)-enhanced in vitro invasion of tissue plasminogen activator (t-PA)-producing endothelial and melanoma cells. Kinetic analyses demonstrated that angiostatin functions as a non-competitive inhibitor of extracellular-matrix (ECM)-enhanced, t-PA-catalysed plasminogen activation, with a Ki of 0.9+/-0.03 microM. This mechanism suggests that t-PA has a binding site for the inhibitor angiostatin, as well as for its substrate plasminogen that, when occupied, prevents ternary complex formation between t-PA, plasminogen and matrix protein. Direct binding experiments confirmed that angiostatin bound to t-PA with an apparent Kd [Kd(app)] of 6.7+/-0.7 nM, but did not bind with high affinity to ECM proteins. Together, these data suggest that angiostatin in the cellular micro-environment can inhibit matrix-enhanced plasminogen activation, resulting in reduced invasive activity, and suggest a biochemical mechanism whereby angiostatin-mediated regulation of plasmin formation could influence cellular migration and invasion.  (+info)

Role of plasminogen system components in focal cerebral ischemic infarction: a gene targeting and gene transfer study in mice. (4/266)

BACKGROUND: The role of plasminogen system components in focal cerebral ischemic infarction (FCI) was studied in mice deficient in plasminogen (Plg-/-), in tissue or urokinase plasminogen activator (tPA-/- or uPA-/-), or in plasminogen activator inhibitor-1 or alpha2-antiplasmin (PAI-1(-/-) or alpha2-AP-/-). METHODS AND RESULTS: FCI was produced by ligation of the left middle cerebral artery and measured after 24 hours by planimetry of stained brain slices. In control (wild-type) mice, infarct size was 7.6+/-1.1 mm3 (mean+/-SEM), uPA-/- mice had similar infarcts (7.8+/-1.0 mm3, P=NS), tPA-/- mice smaller (2.6+/-0.80 mm3, P<0.0001), PAI-1(-/-) mice larger (16+/-0.52 mm3, P<0.0001), and Plg-/- mice larger (12+/-1.2 mm3, P=0.037) infarcts. alpha2-AP-/- mice had smaller infarcts (2. 2+/-1.1 mm3, P<0.0001 versus wild-type), which increased to 13+/-2.5 mm3 (P<0.005 versus alpha2-AP-/-) after intravenous injection of human alpha2-AP. Injection into alpha2-AP-/- mice of Fab fragments of affinospecific rabbit IgG against human alpha2-AP, after injection of 200 microg human alpha2-AP, reduced FCI from 11+/-1.5 to 5.1+/-1.1 mm3 (P=0.004). CONCLUSIONS: Plg system components affect FCI at 2 different levels: (1) reduction of tPA activity (tPA gene inactivation) reduces whereas its augmentation (PAI-1 gene inactivation) increases infarct size, and (2) reduction of Plg activity (Plg gene inactivation or alpha2-AP injection) increases whereas its augmentation (alpha2-AP gene inactivation or alpha2-AP neutralization) reduces infarct size. Inhibition of alpha2-AP may constitute a potential avenue to treatment of FCI.  (+info)

Characterization of wild-type and mutant alpha2-antiplasmins: fibrinolysis enhancement by reactive site mutant. (5/266)

During human blood clotting, alpha2-antiplasmin (alpha2AP) becomes covalently linked to fibrin when activated blood clotting factor XIII (FXIIIa) catalyzes the formation of an isopeptide bond between glutamine at position two in alpha2AP and a specific epsilon-lysyl group in each of the alpha-chains of fibrin. This causes fibrin to become resistant to plasmin-mediated lysis. We found that chemically Arg-modified alpha2AP, which lacked plasmin-inhibitory activity, competed effectively with native alpha2AP for becoming cross-linked to fibrin and as a consequence, enhanced fibrinolysis. Recombinant alpha2AP reported to date by other groups either lacked or possessed a low level of FXIIIa substrate activity. As a first step in the development of an engineered protein that might have potential as a localized fibrin-specific fibrinolytic enhancer, we expressed recombinant alpha2AP in Pichia pastoris yeast. Two forms of nonglycosylated recombinant alpha2AP were expressed, isolated and characterized: (1) wild-type, which was analogous to native alpha2AP, and (2) a mutant form, which had Ala substituted for the reactive-site Arg364. Both the wild-type and mutant forms of alpha2AP functioned as FXIIIa substrates with affinities and kinetic efficiencies comparable to those of native alpha2AP, despite each having an additional acetylated Met blocking group at their respective amino-termini. Wild-type recombinant alpha2AP displayed full plasmin inhibitory activity, while mutant alpha2AP had none. Neither the absence of glycosylation nor blockage of the amino-terminus affected plasmin-inhibitory or FXIIIa substrate activities of wild-type alpha2AP. When our mutant alpha2AP, which lacked plasmin-inhibitory function, was added to human plasma or whole blood clots, urokinase (UK)-induced clot lysis was enhanced in a dose-dependent manner, indicating that mutant alpha2AP augmented lysis by competing with native alpha2AP for FXIIIa-catalyzed incorporation into fibrin.  (+info)

Hepatitis C virus NS3 serine protease interacts with the serpin C1 inhibitor. (6/266)

Both NS3 protein (1007-1657) and its protease moiety (NS3p, 1027-1207) were able to interact in vitro with C1 Inhibitor (C1Inh) to give a 95-kDa Mr C1Inh cleavage product similar to that obtained upon proteolysis by complement protease C1s. High-Mr reaction products were also detected after incubation of C1Inh with NS3 but not with NS3p; they correspond to ester-bonded complexes from their hydroxylamine lability. Similar reactivity of NS3 was observed upon incubation with alpha2-antiplasmin. Serpin cleavage was prevented by treatment of NS3 with synthetic serine protease inhibitors. This interaction between viral NS3 and host serpins suggests that NS3 is likely to be controlled by infected cell protease inhibitors.  (+info)

Solvent/detergent-treated plasma has decreased antitrypsin activity and absent antiplasmin activity. (7/266)

Solvent/detergent (S/D)-treated plasma is currently marketed by the American Red Cross as a virally inactivated alternative to fresh-frozen plasma (FFP). The serpin-type serine proteinase inhibitors have a flexible reactive site loop (RSL) that can convert from the active conformation to the inactive latent or polymerized conformations when exposed to heat and/or detergents. We have compared the conformational stability and inhibitory activity of 3 plasma serpins-antithrombin, antitrypsin, and antiplasmin-in S/D plasma and FFP. In S/D plasma, virtually 100% of the antiplasmin and approximately 50% of the antitrypsin are in either the latent or polymerized conformation and lack inhibitory activity, while in FFP only the active conformation is present. Interestingly, antithrombin is not affected by S/D treatment and remains fully active. These data demonstrate that S/D plasma is not simply a virally inactivated equivalent of FFP. The lack of antiplasmin activity and decreased antitrypsin activity in S/D plasma suggest that it may not be as effective as FFP for the treatment of bleeding in patients with systemic activation of proteolytic cascades, such as disseminated intravascular coagulation and sepsis, acquired fibrinolytic states, and large-volume transfusion. Although there has been extensive use of S/D plasma in several European countries with no reports of adverse effects, clinical studies directly comparing the efficacy of these 2 plasma products are needed to directly evaluate the relative therapeutic efficacy of FFP and S/D plasma for the treatment of these diseases.  (+info)

Comparative effects of tissue plasminogen activator, streptokinase, and staphylokinase on cerebral ischemic infarction and pulmonary clot lysis in hamster models. (8/266)

BACKGROUND: The effects of alteplase (rtPA), streptokinase, and staphylokinase (rSak) on focal cerebral ischemia (FCI) and on pulmonary clot lysis (PCL) were studied in hamsters. METHODS AND RESULTS: ++FCI was produced by ligation of the left middle cerebral artery (MCA) and common carotid artery (CCA) and a 10-minute occlusion of the right CCA. FCI was measured after 24 hours by 2,3, 5-triphenyltetrazolium chloride staining. (125)I-fibrin-labeled plasma clots were injected via the jugular vein, and clot lysis was determined from residual radioactivity at 90 minutes. Study drugs were given intravenously over 60 minutes. FCI increased from 1.2 (0. 27 to 2.3) mm(3) (median and 17th to 83rd percentile range, n=24) in controls to 19 to 27 mm(3) with thrombolytic agent, with maximal rates at 0.13+/-0.05 mg/kg rtPA, 0.23+/-0.09 mg/kg streptokinase, and 0.037+/-0.025 mg/kg rSak. PCL increased from 18+/-2% (mean+/-SEM, n=27) in controls to approximately 85% with thrombolytics, with maximal rates at 0.12+/-0.03 mg/kg rtPA, 0.17+/-0.05 mg/kg streptokinase, and 0.018+/-0.002 mg/kg rSak. All agents caused maximal FCI and PCL rates at similar doses without alpha(2)-antiplasmin and fibrinogen depletion. Injection of 6 mg/kg human plasminogen combined with streptokinase caused a "systemic fibrinolytic state" with fibrinogen depletion. Maximal rates of FCI were obtained with 0.097+/-0.077 mg/kg streptokinase (P=0.26 versus streptokinase alone) and of PCL with 0.010+/-0.002 mg/kg (P=0.006 versus streptokinase alone). CONCLUSIONS: Thrombolytic agents cause similar dose-related extension of FCI after MCA ligation and PCL, irrespective of the agent or systemic plasmin generation.  (+info)

In the measurement of plasmin inhibitor three reactions of plasmin are of importance. First is the reaction with the PB-form of the plasmin inhibitor. Second is the reaction with the NPB-form of the plasmin inhibitor and third the reaction with a 2 -macroglobulin. Using a small excess of plasmin ( approx. 1 m M), all three reactions take place as a second order reaction ([plasmin inhibitor] total approx. [plasmin] total ). At a plasmin inhibitor concentration of 1 m M gives this a velocity for the plasmin-PB-plasmin inhibitor complex formation of 27 s -1 . For the plasmin-NPB-plasmin inhibitor complex formation this is 0.2 s -1 and for the plasmin- a 2 -macroglobulin complex formation this is 1.0 s -1 . Expressed in ratios of the complexes this is 95.7% for the plasmin-PB-plasmin inhibitor complex, 0.7% for the plasmin-NPB-plasmin inhibitor complex and 3.6% for the plasmin- a 2 -macroglobulin complex ...

Bovine platelet plasmin inhibitor (BPPI) is a novel Kunitz inhibitor, recently discovered in platelets (Li, 1992) for which an expression system is sought. Because the proteins origin of synthesis was unknown, a search for a genomic clone was undertaken. PCR was used in an attempt to amplify the BPPI gene from lymphocyte, bovine genomic DNA. The first set of primers used was designed according to the N and C termini of the amino acid sequence of BPPI (P1/P2). These were based on a degenerate nucleotide sequence derived from its amino acid sequence. Amplification with this set of primers was unsuccessful. The second approach in amplifying the gene was to increase the specificity of the primers in the 3 end (P3/P4) using a table of codon usage of the bovine genome. Two successive amplifications led to the formation of a 230 bp fragment. The sequence of this product was not comparable to the degenerate sequence of BPPI. A third set of primers (P6/P7) was designed according to the gene sequence of SI (II)

Inhibition of Fibrinolysis. For maintaining high fidelity regulation between coagulatory clotting and proteolytic fibrinolysis TAFI (Thrombin activatable fibrinolysis inhibitor) plays an important inhibitory role. Apart from this, four different forms of plasminogen activator inhibitors, denoted PAI-1 to PAI-4, are also known.. PAI-1, which is the most prominent form, is mainly synthesized in endothelial cells and stored in thrombocytes. Its release is concentrated to platelet rich clots leading to an increased thrombus resistance to fibrinolysis. Another fibrinolysis inhibitor is the plasmin inhibitor (α2-antiplasmin). FXIIIa makes it an initial clot stabilizer by rapidly and covalently binding this inhibitor to fibrin. The role of inhibiting plasmin is made directly by a 1:1-complex formation between plasmin and antiplasmin (PAP). PAP can be immunologically detected in plasma, and is therefore used as a diagnostic parameter for proving thrombosis.. Function of plasmin. The fibrinogen molecule ...

Starting with 1130 plasma proteins, we previously derived and then externally validated a 9 protein model (CVD9 [angiopoietin 2, complement C7, α-2 antiplasmin, matrix metalloproteinase 12, α-1 antichymotrypsin complex, growth differentiation factors 11/8, chemokine (C-C motif) ligand 18, angiopoietin related protein 4 and troponin I]) to predict 4-year probability of death, myocardial infarction, stroke and heart failure using SOMAscan proteomic technology in subjects with stable coronary heart disease (CHD). In the current study, we tested whether this proteomic risk score increases within individuals as they approach an event. We applied CVD9 to paired plasma samples from 513 subjects in the Heart and Soul study who were still event free when a second blood sample was taken 4.8 years after the first. There were 139 subjects who had events a median of 2.9 years after their second sample, compared to 374 subjects who did not have events after their second sample (with a median of 4.3 years of ...

TY - CHAP. T1 - Plasmin-antiplasmin system. AU - Mutch, Nicola J.. AU - Booth, Nuala A.. PY - 2016/4/19. Y1 - 2016/4/19. N2 - Plasmin is the key enzyme involved in the dissolution of fibrin. It is produced from plasminogen, which is activated by a plasminogen activator; the two primary activators are tissue-type plasminogen activator (tPA) and urinary-type plasminogen activator (uPA), also called urokinase. The process is regulated by inhibitors, principally plasminogen activator inhibitor 1 (PAI-1), α2-antiplasmin (α2AP) and thrombin-activatable fibrinolysis inhibitor (TAFI). Crucial control is exerted by surfaces, such as fibrin or cells, with plasminogen activation not normally occurring in the circulation. Here we will consider the individual players of the fibrinolytic cascade and their specific locations and potential interactions. Key questions considered are the initiation of fibrinolysis and the most appropriate ways to measure abnormalities in disease situations.. AB - Plasmin is the ...

METHODS AND RESULTS Fifty-five patients were treated with urokinase-preactivated prourokinase (n = 35) or tissue-type plasminogen activator (n = 20) for acute myocardial infarction and underwent coronary angiography at 90 minutes and at 24-36 hours into thrombolysis, and fibrinogen (Ratnoff-Menzie), D-dimer (ELISA) and thrombin-antithrombin III complex levels (ELISA) were measured. Primary patency was achieved in 39 patients (70.9%), 13 of whom (33.3%) suffered early reocclusion. Nonsignificant decreases in fibrinogen levels were observed while D-dimer levels increased +3,008 +/- 4,047 micrograms/l (p less than 0.01), differences not being significant in respect to the thrombolytic agents or to the clinical course. In contrast, while thrombin-antithrombin III complex levels decreased -4.4 +/- 13.0 micrograms/l in patients with persistent patency, they increased +7.5 +/- 13.6 micrograms/l in case of nonsuccessful thrombolysis (p less than 0.02) and +11.9 +/- 23.8 micrograms/l in case of early ...
The present study was undertaken to determine whether highly purified human urinary trypsin inhibitor (UTI) efficiently inhibits the soluble and the tumor cell receptor-bound plasmin. The ability of plasmin inhibitors to regulate invasion by tumor cells which express membrane-associated plasmin was also examined. UTI and two other plasmin inhibitors [α2-anti-plasmin (α2AP) and α2-macroglobulin (α2M)] were used. α2AP and α2M, as well as UTI, rapidly inactivate the soluble plasmin that is not bound to cells. Experiments were performed in vitro using cultures of ovarian cancer HOC-I cells and gestational choriocarcinoma SMT-ccl cells. HOC-I and SMT-ccl cells had plasmin(ogen) on their cell surface, and the plasmin activity was detected on their cell surface enzymologically and immunologically. Receptor-bound plasmin reacted effectively with UTI and was directly inactivated by UTI. In contrast, receptor-bound plasmin was not inhibited by α2AP and α2M. Using a modified Boyden chamber and an ...

Relying on virtual screening and the 3-dimensional structure of the complex of PAI-1 with its inhibitory peptide, we have identified 2 novel, orally bioavailable, small molecule PAI-1 inhibitors, TM5001 and TM5007. Both are stable, nontoxic, and devoid of cellular toxicity as demonstrated in vitro by their inability to raise LDH levels in the medium of cultured HeLa cells. The absence of acute and subacute toxicity is confirmed in vivo in mice given a single dose of up to 2000 mg/kg, or in rats fed 300 mg/kg for 1 week or 2000 mg/kg for 2 weeks. The in vivo effectiveness of TM5007 is demonstrated in animal models of either acute vascular thrombosis or of chronic lung fibrosis, without deleterious effects on blood pressure or bleeding, in good agreement with previous results in PAI-1 deficient mice and humans.8,14. The specificity of the effect of TM5007 on PAI-I was further documented in other serpin/serine protease systems (ie, α1-antitrypsin/trypsin and α2-antiplasmin/plasmin) by a ...

Background:This study analyzes the influence the of kidney donor hemostasis on the risk of complications in the kidney recipient after transplantation. Material and Methods:We enrolled 38 deceased kidney donors, of whom14 donors died from a physical injury and the others died from ischemic or bleeding central nervous system stroke. The donors were categorized into 2 subgroups. If the recipients postoperative period proceeded smoothly, the kidney donor was assigned to the uncomplicated donors (UD) group. If the recipients postoperative period was complicated, the donor was assigned to the complicated (CD) Group. The CD group of consisted of 9 donors who died from strokes or bleedings and 2 who died from physical injury. We examined the antithrombin (AT) protein C (PC), complexes of thrombin/antithrombin (TAT), fragments F1+2 of prothrombin (F1+2), plasminogen (Pl), complexes of plasmin/antiplasmin (PAP), and D-dimers (D-d). Results:In the CD group had decreased activity of AT, PC, and Pl and increased

3.1 Theory. We have been looking at how new complex systems can emerge from non-linear field interactions, where feedback loops replace simple linear cause-and-effect chains. We have looked at the increasingly complex levels of life, intelligence and choicefulness. The question I want to explore in this chapter is: how does this happen in the case of our emergent conscious self? What are the "nuts and bolts" of the interactions leading to my ability to be myself?. Notice how this is immediately a different question from the more familiar ones of how conscious self affects the environment, or vice versa. Both of these assume a primary separation of self from environment, so that the interactions each way can be charted. But using the "three boundaries" language from Chapter Two, we can see how this oversimplifies the situation. "Self" and "environment" do not belong to the same level of interaction. Environment engages with organism at the physical contact boundary; self engages with other at the ...

Plasmin-induced tissue degradation contributes to the proliferation of most diseases. Of particular interest is the fact that similar mechanisms are induced by attacking pathogens as they are used by the defending host cells, e.g. macrophages. In many pathological conditions macrophages become activated. This activation reflects a particular state of alert that is characterized by an abundant release of secretory products. These products include oxygen metabolites, collagenases, elastases, and a significantly increased secretion of plasminogen activators. It is immediately obvious that this mechanism needs to be precisely controlled. Therefore macrophages also secrete inhibitory products including plasmin inhibitors and a2-macroglobulin which are able to inactivate plasmin and many other proteases. Any imbalance in this control system leads to an exacerbation of this mechanism and to continued tissue degradation. Chronic activation of macrophages and an exertion of the control mechanisms ...
