Increased collagenase and dipeptidyl peptidase I activity in leucocytes from healthy elderly people. (1/128)

The incidence of infectious diseases increases with ageing. The enzymatic activity of leucocytes may have a relevant role in the morbidity and mortality due to infections in the elderly. In this study we have compared the activity of enzymes involved in the inflammatory response in leucocytes from young and elderly women. A total of 35 healthy females was studied, 20 volunteers aged 78-98 years (mean 89.1 years) and 15 young controls aged 19-34 years (mean 26 years). All of them were in good clinical condition, without any acute or chronic disease. Intracellular enzyme activity was analysed by flow cytometry in leucocytes from young and elderly women. The enzyme substrates employed were for oxidative burst, L-aminopeptidase, collagenase, cathepsin B, C, D and, G and dipeptidyl peptidase I. The intracellular enzyme activity assessed by flow cytometry in leucocytes from young and elderly women was similar, as far as oxidative burst, L-aminopeptidase, cathepsin B, C, D and G are concerned. An increased collagenase activity was detected in granulocytes from elders. The mean fluorescence channels for this enzyme corresponded to 86 +/- 23 and 60 +/- 15 in cells from elders and controls, respectively (P = 0.01224). An increased dipeptidyl peptidase I activity was detected in lymphocytes from elderly women. The corresponding values for this enzyme in elders and the young were 65.9 +/- 43.3 and 17.3 +/- 5, respectively (P = 0. 0036). The proper functional activity of intracellular enzymes involved in inflammatory responses is likely to be determinant for successful ageing.  (+info)

Dipeptidyl peptidase I is required for the processing and activation of granzymes A and B in vivo. (2/128)

Dipeptidyl peptidase I (DPPI) is a lysosomal cysteine protease that has been implicated in the processing of granzymes, which are neutral serine proteases exclusively expressed in the granules of activated cytotoxic lymphocytes. In this report, we show that cytotoxic lymphocytes derived from DPPI-/- mice contain normal amounts of granzymes A and B, but these molecules retain their prodipeptide domains and are inactive. Cytotoxic assays with DPPI-/- effector cells reveal severe defects in the induction of target cell apoptosis (as measured by [(125)I]UdR release) at both early and late time points; this defect is comparable to that detected in perforin-/- or granzyme A-/- x B-/- cytotoxic lymphocytes. DPPI therefore plays an essential role in the in vivo processing and activation of granzymes A and B, which are required for cytotoxic lymphocyte granule-mediated apoptosis.  (+info)

Location of the binding site for chloride ion activation of cathepsin C. (3/128)

Cathepsin C, a tetrameric lysosomal dipeptidyl-peptide hydrolase, is activated by chloride ion. The activation is shown here to be specific and pH-dependent, dissociation constants for chloride being lower at low pH. Bound chloride decreases the Km for the hydrolysis of chromophore labelled substrates without any significant change in Vmax, confirming its involvement in substrate binding. Determination of the kinetic parameters of chloride activation, using unlabelled substrates, has enabled its site of action to be located. The lower Km for the hydrolysis of simple amide substrates in the presence of Cl- shows that the S sites are involved. Possible involvement of the S' sites is excluded by the finding that the Km for the nucleophile in the transferase reaction is unaffected by chloride. The rates of inhibition by E-64 and iodoacetate are both chloride-dependent and, from the structure of the papain-E-64 complex, it is concluded that chloride binds close to the S2 site. The binding of guanidinium ion, a positively charged inhibitor, to the S site is dependent on chloride. Based on these results, a model is proposed to explain the chloride activation of cathepsin C. The possible physiological role of chloride in the regulation of proteolysis in the lysosome is discussed.  (+info)

Mutations of the cathepsin C gene are responsible for Papillon-Lefevre syndrome. (4/128)

Papillon-Lefevre syndrome (PLS) is an autosomal recessive disorder characterised by palmoplantar hyperkeratosis and severe early onset periodontitis that results in the premature loss of the primary and secondary dentitions. A major gene locus for PLS has been mapped to a 2.8 cM interval on chromosome 11q14. Correlation of physical and genetic maps of this interval indicate it includes at least 40 ESTs and six known genes including the lysosomal protease cathepsin C gene (CTSC). The CTSC message is expressed at high levels in a variety of immune cells including polymorphonuclear leucocytes, macrophages, and their precursors. By RT-PCR, we found CTSC is also expressed in epithelial regions commonly affected by PLS, including the palms, soles, knees, and oral keratinised gingiva. The 4.7 kb CTSC gene consists of two exons. Sequence analysis of CTSC from subjects affected with PLS from five consanguineous Turkish families identified four different mutations. An exon 1 nonsense mutation (856C-->T) introduces a premature stop codon at amino acid 286. Three exon 2 mutations were identified, including a single nucleotide deletion (2692delA) of codon 349 introducing a frameshift and premature termination codon, a 2 bp deletion (2673-2674delCT) that results in introduction of a stop codon at amino acid 343, and a G-->A substitution in codon 429 (2931G-->A) introducing a premature termination codon. All PLS patients were homozygous for cathepsin C mutations inherited from a common ancestor. Parents and sibs heterozygous for cathepsin C mutations do not show either the palmoplantar hyperkeratosis or severe early onset periodontitis characteristic of PLS. A more complete understanding of the functional physiology of cathepsin C carries significant implications for understanding normal and abnormal skin development and periodontal disease susceptibility.  (+info)

Haim-Munk syndrome and Papillon-Lefevre syndrome are allelic mutations in cathepsin C. (5/128)

Of the many palmoplantar keratoderma (PPK) conditions, only Papillon-Lefevre syndrome (PLS) and Haim-Munk syndrome (HMS) are associated with premature periodontal destruction. Although both PLS and HMS share the cardinal features of PPK and severe periodontitis, a number of additional findings are reported in HMS including arachnodactyly, acro-osteolysis, atrophic changes of the nails, and a radiographic deformity of the fingers. While PLS cases have been identified throughout the world, HMS has only been described among descendants of a religious isolate originally from Cochin, India. Parental consanguinity is a characteristic of many cases of both conditions. Although autosomal recessive transmission of PLS is evident, a more "complex" autosomal recessive pattern of inheritance with phenotypic influences from a closely linked modifying locus has been hypothesised for HMS. Recently, mutations of the cathepsin C gene have been identified as the underlying genetic defect in PLS. To determine if a cathepsin C mutation is also responsible for HMS, we sequenced the gene in affected and unaffected subjects from the Cochin isolate in which both the PLS and HMS phenotypes appear. Here we report identification of a mutation of cathepsin C (exon 6, 2127A--> G) that changes a highly conserved amino acid in the cathepsin C peptide. This mutation segregates with HMS in four nuclear families. Additionally, the existence of a shared common haplotype for genetic loci flanking the cathepsin C gene suggests that affected subjects descended from the Cochin isolate are homozygous for a mutation inherited "identical by descent" from a common ancestor. This finding supports simple autosomal recessive inheritance for HMS in these families. We also report a mutation of the same exon 6 CTSC codon (2126C-->T) in a Turkish family with classical PLS. These findings provide evidence that PLS and HMS are allelic variants of cathepsin C gene mutations.  (+info)

Localisation of a gene for prepubertal periodontitis to chromosome 11q14 and identification of a cathepsin C gene mutation. (6/128)

Prepubertal periodontitis (PPP) is a rare and rapidly progressive disease of young children that results in destruction of the periodontal support of the primary dentition. The condition may occur as part of a recognised syndrome or may occur as an isolated finding. Both autosomal dominant and recessive forms of Mendelian transmission have been reported for PPP. We report a consanguineous Jordanian family with four members affected by PPP in two nuclear sibships. The parents of the affected subjects are first cousins. We have localised a gene of major effect for PPP in this kindred (Zmax=3.55 for D11S901 at theta=0.00) to a 14 cM genetic interval on chromosome 11q14 flanked by D11S916 and D11S1367. This PPP candidate interval overlaps the region of chromosome 11q14 that contains the cathepsin C gene responsible for Papillon-Lefevre and Haim-Munk syndromes. Sequence analysis of the cathepsin C gene from PPP affected subjects from this Jordanian family indicated that all were homozygous for a missense mutation (1040A-->G) that changes a tyrosine to a cysteine. All four parents were heterozygous carriers of this Tyr347Cys cathepsin C mutation. None of the family members who were heterozygous carriers for this mutation showed any clinical findings of PPP. None of the 50 controls tested were found to have this Tyr347Cys mutation. This is the first reported gene mutation for non-syndromic periodontitis and shows that non-syndromic PPP is an allelic variant of the type IV palmoplantar ectodermal dysplasias.  (+info)

Arginine-based structures are specific inhibitors of cathepsin C. Application of peptide combinatorial libraries. (7/128)

Novel synthetic peptide inhibitors of lysosomal cysteine proteinase cathepsin C have been designed through the use of soluble peptide combinatorial libraries. The uncovered structural inhibitory module consists of the N-terminal cluster of L-arginine residues. Its modification with D-amino acids or arginine derivatives did not increase the inhibition strength. Inhibitory potency of oligoarginines improves with the elongation of peptide chain reaching a maximum for octa-L-arginine. The oligoarginines specifically interact with the cathepsin C active site as shown by competitive-type inhibition kinetics (Ki approximately 10-5 M) and intrinsic fluorescence measurements. The inhibitory interaction of oligoarginines is established through the specific spatial contact of a net of guanidino groups in the arginine side-chains, as indicated by comparison with inhibitory action of low molecular mass guanidine derivatives (Ki approximately 10-3 M). Nonarginine polyionic compounds cannot mimic the inhibitory effect of oligoarginines. The arginine-based peptide inhibitors were selective towards cathepsin C among other cysteine proteinases tested.  (+info)

Programming for cytotoxic effector function occurs concomitantly with CD4 extinction during CD8(+) T cell differentiation in the thymus. (8/128)

CD4(+) T cells are generally specialized to function as helper cells and CD8(+) T cells are generally specialized to function as cytotoxic effector cells. To explain how such concordance is achieved between co-receptor expression and immune function, we considered two possibilities. In one case, immature CD4(+)CD8(+) thymocyte precursors might first down-regulate expression of one co-receptor molecule, with the remaining co-receptor molecule subsequently activating the appropriate helper or cytotoxic functional program. Alternatively, we considered that the same intrathymic signals that selectively extinguished expression of one or the other co-receptor molecule might simultaneously initiate the appropriate helper or cytotoxic functional program. In the present study, we attempted to distinguish between these alternatives by examining thymocyte precursors of CD8(+) T cells for expression of Cathepsin C and Cathepsin W, molecules important for cytotoxic effector function. We report in developing thymocytes that Cathepsin C and Cathepsin W are expressed coordinately with extinction of CD4 co-receptor expression. We conclude that CD4 extinction and initiation of the cytotoxic functional program occurs simultaneously during differentiation of CD8(+) T cells in the thymus.  (+info)

Cathepsin C (CTSC) also known as dipeptidyl peptidase I (DPP-I) is a lysosomal exo-cysteine protease belonging to the peptidase C1 family. In humans, it is encoded by the CTSC gene. Cathepsin C appears to be a central coordinator for activation of many serine proteases in immune/inflammatory cells. Cathepsin C catalyses excision of dipeptides from the N-terminus of protein and peptide substrates, except if (i) the amino group of the N-terminus is blocked, (ii) the site of cleavage is on either side of a proline residue, (iii) the N-terminal residue is lysine or arginine, or (iv) the structure of the peptide or protein prevents further digestion from the N-terminus. The cDNAs encoding rat, human, murine, bovine, dog and two Schistosome cathepsin Cs have been cloned and sequenced and show that the enzyme is highly conserved. The human and rat cathepsin C cDNAs encode precursors (prepro-cathepsin C) comprising signal peptides of 24 residues, pro-regions of 205 (rat cathepsin C) or 206 (human ...
Background: PLS is a rare autosomal recessive disorder characterized by early onset periodontopathia and palmar plantar keratosis. PLS is caused by mutations in the cathepsin C (CTSC) gene. Dipeptidyl-peptidase I encoded by the CTSC gene removes dipeptides from the aminoterminus of protein substrates and mainly plays an immune and inflammatory role. Several mutations have been reported in this gene in patients from several ethnic groups. We report here mutation analysis of the CTSC gene in three Indian families with PLS. Methods: Peripheral blood samples were obtained from individuals belonging to three Indian families with PLS for genomic DNA isolation. Exon-specific intronic primers were used to amplify DNA samples from individuals. PCR products were subsequently sequenced to detect mutations.PCR-SCCP and ASOH analyses were used to determine if mutations were present in normal control individuals. Results: All patients from three families had a classic PLS phenotype, which included ...

The mechanism of toxicity for cytolytic lymphocytes of Leu-Leu-OMe and related dipeptide derivatives was examined. Selective inhibition of dipeptidyl peptidase I (DPPI), a lysosomal thiol protease highly enriched in cytotoxic lymphocytes, prevented all natural killer (NK) toxic effects of such agents. However, many DPPI substrates were found to possess no NK toxic properties. For some such agents, this lack of NK toxicity appeared to be related to the lack of uptake by lymphocytes. In this regard, Leu-Leu-OMe was found to be incorporated by lymphocytes and monocytes via a saturable facilitated transport mechanism with characteristics distinct from previously characterized mammalian dipeptide transport processes. This novel transport process was found to be specific for dipeptides composed of selective L-stereoisomer amino acids and enhanced by hydrophobic ester or amide additions to the COOH terminus of dipeptides. Maximal rates of Leu-Leu-OMe uptake by T8 and NK cell-enriched peripheral blood ...
The dipeptide glycyl-l-phenylalanine 2-naphthylamide (GPN) is widely used to perturb lysosomes because its cleavage by the lysosomal enzyme cathepsin C is proposed to rupture lysosomal membranes. We show that GPN evokes a sustained increase in lysosomal pH (pHly), and transient increases in cytosolic pH (pHcyt) and Ca2+ concentration ([Ca2+]c). None of these effects require cathepsin C, nor are they accompanied by rupture of lysosomes, but they are mimicked by structurally unrelated weak bases. GPN-evoked increases in [Ca2+]c require Ca2+ within the endoplasmic reticulum (ER), but they are not mediated by ER Ca2+ channels amplifying Ca2+ release from lysosomes. GPN increases [Ca2+]c by increasing pHcyt, which then directly stimulates Ca2+ release from the ER. We conclude that physiologically relevant increases in pHcyt stimulate Ca2+ release from the ER in a manner that is independent of IP3 and ryanodine receptors, and that GPN does not selectively target lysosomes. ...

The Papillon-Lefèvre syndrome or keratosis palmoplantaris associated to periodontopathy was first described by Papillon-Lefèvre, in 1924. It is an autosomal recessive genetic disease, with alteration in the gene CTSC, located in chromosome 11q14.1-q14.4, more precisely in the protein called cathepsin C (Hart et al., 2000; Shafer et al., 1987; Neville et al., 2001; Tommasi, 2002; Allende & Moreno, 2003; Hewitt et al., 2004; Selvaraju et al., 2003 ). It affects children and young adults of both sexes with no distinction. It is a very rare disease, with a prevalence of one in one million individuals. Its main oral clinical characteristics include periodontopathies, premature loss of deciduous teeth, at the age of 4-5 years and of the permanent teeth at approximately 14 years (Allegra & Gennari, 2000; Regezi & Sciubba, 2000; Tommasi, 2002; Siragusa et al., 2000). According to Shafer et al. (1987), only the permanent dentition is affected in some cases.. Patients also present halitosis, intense ...

Upon stimulation, polymorphonuclear leucocytes (PMNs) release potent serine proteases, i.e. elastase, cathepsin C and proteinase 3, which contribute to the degradation of tissue and plasma components. Here, we describe the development of a plasma test to assess PMN-mediated fibrinogenolysis as a biochemical marker for actual PMN-derived proteolysis in vivo, useful for monitoring therapeutic efficacy, i.e. of elastase inhibitors. We generated a monoclonal antibody (MAb), designated 1-1/B3, with a high affinity for elastase-degraded fibrinogen (EDF). The epitope for 1-1/B3 becomes exposed in a time-dependent manner during digestion of fibrinogen with purified PMN-derived serine proteases and with isolated PMNs in vitro. However, 1-1/B3 does not react with plasma fibrinogen or with fibrin(ogen) degradation products generated by plasmin or by other active proteases that may occur locally, i.e. metalloproteases and lysosomal cathepsins. On the basis of MAb 1-1/B3, we developed a plasma test for the ...

From NCBI Gene:. This gene encodes a member of the peptidase C1 family and lysosomal cysteine proteinase that appears to be a central coordinator for activation of many serine proteinases in cells of the immune system. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate heavy and light chains that form a disulfide-linked dimer. A portion of the propeptide acts as an intramolecular chaperone for the folding and stabilization of the mature enzyme. This enzyme requires chloride ions for activity and can degrade glucagon. Defects in the encoded protein have been shown to be a cause of Papillon-Lefevre syndrome, an autosomal recessive disorder characterized by palmoplantar keratosis and periodontitis.

Glutamine supplementation has been advocated for patients requiring parenteral nutritional support. However, the direct effect of glutamine on neoplastic cells is poorly understood. We therefore investigated the effects of glutamine on the proliferation, differentiation, and cell-matrix interactions of two human colon carcinoma cell lines (Caco-2 and SW620) adapted to glutamine-free media. Doubling times were calculated by logarithmic transformation of serial cell counts. Alkaline phosphatase, cathepsin C (dipeptidyl peptidase), lactase, and isomaltase expression (markers of differentiation) were assayed by digestion of synthetic substrates. Adhesion to matrix proteins was assessed by colorimetric quantitation of toluidine blue staining of adherent cells. Surface expression of Caco-2 receptors for matrix proteins (integrins) was studied by biotinylation and immunoprecipitation with specific antibodies. Glutamine (1-10 mm) dose-dependently stimulated Caco-2 proliferation on all matrices studied ...

Apoptose er programmert celledød for å fjerne uønskede celler og er en felles egenskap for alle flercellede organismer. Caspase-3 er involvert i intracellulære signalkaskader ved apoptose. En ubalanse i regulering av apoptose kan føre til kreftutvikling. Apoptose spiller en viktig rolle i flere andre sykdommer som immunologisk, iskemiske, og nevrodegenerative sykdommer. For å undersøke betydningen av proteasen legumain og proteaseinhibitoren cystatin E/M for caspase-3 aktivitet, ble det brukt HEK293 (normale kontroll celler), M38L (overutrykker legumain) og M4C (overutrykker cystatin E/M) celler. Cellene ble stimulert med dødsstimulerende stoffer som staurosporin og Leu-Leu-OMe. Staurosporin er kjent for å være en kinasehemmer. Leu-Leu-OMe øker lysosomal membranpermeabilitet. Proteaser som er involvert i apoptose vil dermed frigjøres fra lysosomer til cytosol. Legumain som befinner seg i lysosomene, kan frigjøres til cytosol og dermed påvirke aktiviteten av caspase-3 eller andre ...
Cathepsin B is an enzymatic protein belonging to the peptidase (or protease) families. In humans, it is coded by the CTSB gene. The protein encoded by this gene is a lysosomal cysteine protease composed of a dimer of disulfide-linked heavy and light chains, both produced from a single protein precursor. It is a member of the peptidase C1 family. At least five transcript variants encoding the same protein have been found for this gene.

Complexes of gold( I) have long been used to treat rheumatoid arthritis although the precise biological targets of gold are not well understood. One intriguing therapeutic target of Au( I) is the cathepsin family of lysosomal cysteine proteases. Here, we present the inhibition of cathepsin B by a known Au( I)-based drug and a series of derivatives. The complexes investigated were reversible, competitive inhibitors with IC50 values ranging from 0.3 to 250 mu M, depending on the substituents around the Au( I). ...
Dipeptidyl-peptidase 3 is an enzyme that in humans is encoded by the DPP3 gene. This gene encodes a protein that is a member of the S9B family in clan SC of the serine proteases. This cytoplasmic protein binds a single zinc ion with its zinc-binding motif (HELLGH) and has post-proline dipeptidyl aminopeptidase activity, cleaving Xaa-Pro dipeptides from the N-termini of proteins. Increased activity of this protein is associated with endometrial and ovarian cancers. Alternate transcriptional splice variants have been characterized.

The presence of DPPII (dipeptidyl peptidase II; E.C. has been demonstrated in various mammalian tissues. However, a profound molecular and catalytic characterization, including substrate selectivity, kinetics and pH-dependence, has not been conducted. In the present study, DPPII was purified from human seminal plasma to apparent homogeneity with a high yield (40%) purification scheme, including an inhibitor-based affinity chromatographic step. The inhibitor lysyl-piperidide (Ki~0.9 μM at pH 5.5) was chosen, as it provided a favourable affinity/recovery ratio. The human enzyme appeared as a 120 kDa homodimer. Mass spectrometric analysis after tryptic digestion together with a kinetic comparison indicate strongly its identity with QPP (quiescent cell proline dipeptidase), also called dipeptidyl peptidase 7. pH profiles of both kcat and kcat/Km clearly demonstrated that DPPII/QPP possesses an acidic and not a neutral optimum as was reported for QPP. Kinetic parameters of the human ...
Purpose: The olfm1 gene encodes a secreted glycoprotein highly conserved in vertebrates. There are two olfm1 genes in zebrafish, olfm1a and olfm1b. Both of these genes are expressed in the brain and retina starting from 16 h post fertilization to adults. We generated a null mutant of both olfm1a and olfm1b genes and analyzed its retinal structure and visual function.. Methods: Olfm1a and olfm1b mutant alleles with nonsense point mutations were obtained from the Wellcome Trust Sanger Institute. Olfm1a and olfm1b null mutants were bred to generate double null mutant (olfm1a/b null). Spontaneous movement, optokinetic and optomotor responses, behavioral responses to light increments and decrements and electroretinogram (ERG) to increased (ON) and decreased (OFF) illumination were compared between olfm1a/b null and wild-type larvae 7 days post fertilization (dpf). The retinal morphology was examined by immunostaining of frozen sections. Total RNA was isolated from 3 and 7 dpf larvae for RNA ...
Korpos et al. (1) claim that limited information exists on the nature of the ECM [extracellular matrix] of the pancreas and, in particular, on the composition of peri-islet capsule, and that they provide the the first comprehensive analysis of the [ECM] composition of peri-islet capsules.. We dispute the strength of these claims. In mice we originally reported in 2008 that a basement membrane (BM) exists around islets, and eight unique components were identified (type IV collagens α1, α2, laminin α2, β1, γ1, nidogen 1, nidogen 2, perlecan) as well as two composite components (laminin Engelbreth-Holm-Swarm, collagen IV) (2). It was also shown that type IV collagens α3, α4, α5, α6 were not present (2). Korpos et al. (1) were able to find a further three unique components (laminin α4, β2, agrin) and one composite component (laminin 322).. In 2008 in humans (3,4), at least four unique components (laminin α1, α5, β1, γ1) were identified and in their Supplementary Figure 1 staining ...
