Abstract
An uncontrolled activity of neutrophil serine proteases (NSPs) contributes to inflammatory diseases. Cathepsin C (CatC) is known to activate NSPs during neutrophilic differentiation and represents a promising pharmacological target in NSP-mediated diseases. In humans, Papillon-Lefèvre syndrome (PLS) patients have mutations in theirCTSC gene, resulting in the complete absence of CatC activity. Despite this, low residual NSP activities are detected in PLS neutrophils (<10% vs healthy individuals), suggesting the involvement of CatC-independent proteolytic pathway(s) in the activation of proNSPs. This prompted us to characterize CatC-independent NSP activation pathways by blocking proCatC maturation. In this study, we show that inhibition of intracellular CatS almost completely blocked CatC maturation in human promyeloid HL-60 cells. Despite this, NSP activation was not significantly reduced, confirming the presence of a CatC-independent activation pathway involving a CatC-like protease that we termed NSPs-AAP-1. Similarly, when human CD34+ progenitor cells were treated with CatS inhibitors during neutrophilic differentiation in vitro, CatC activity was nearly abrogated but ∼30% NSP activities remained, further supporting the existence of NSPs-AAP-1. Our data indicate that NSPs-AAP-1 is a cysteine protease that is inhibited by reversible nitrile compounds designed for CatC inhibition. We further established a proof of concept for the indirect, although incomplete, inhibition of NSPs by pharmacological targeting of CatC maturation using CatS inhibitors. This emphasizes the potential of CatS as a therapeutic target for inflammatory diseases. Thus, preventing proNSP maturation using a CatS inhibitor, alone or in combination with a CatC/NSPs-AAP-1 inhibitor, represents a promising approach to efficiently control the extent of tissue injury in neutrophil-mediated inflammatory diseases.

Abstract
BACKGROUND Papillon Lefevre syndrome (PLS) is an autosomal recessive disorder that results from a mutated gene that encodes a lysosomal peptidase known as cathepsin C (CTSC). The clinical presentation of PLS involves mainly palmoplantar keratosis and periodontitis with a variable degree of severity. SUBJECTS and methods: Our study included ten patients with a broad spectrum of palmoplantar keratosis and periodontitis severity. CTSC variants were detected by Sanger sequencing. CTSC protein secreted in urine was detected by western blotting. RESULTS Five patients have missense variants, Four have nonsense variants, and one has splice variants in CTSC. The activation products of cathepsin C protein (Heavy and light chains) were absent in all patients' urine samples except one with a significantly reduced level compared to the controls. The dimeric form of CTSC protein was found in all the studied cases. The monomeric form was found in five cases. The products of proteolytic activation of CTSC by other cathepsins (L and S) were found in the urine samples of five of the patients. Each patient had a characteristic pattern of accumulated CTSC protein maturation/activation substrates, intermediates, and products. 40% of the patients had the activation products of other lysosomal cathepsins. CONCLUSION Urinary CTSC in PLS patients could be used as a diagnostic biomarker for the biochemical screening of the disease. Different variants in CTSC result in different profiles of CTSC secreted in the urine of PLS patients. The profiles of secreted CTSC in urine could be correlated to the severity of palmoplantar keratosis.

Abstract
Background: Palmar-plantar hyperkeratosis and severe early-onset periodontitis are the hallmarks of the uncommon autosomal recessive Papillon-Lefévre syndrome (PLS), which may cause both primary and permanent teeth to be lost at an early age. The cause and pathophysiology of the disorder involve several factors, including genetic, immunological, and microbial factors. Aim: The purpose of this case study is to provide insight into the fascinating role of consanguinity in the aetiology of this unusual illness. Case Presentation: An unusual PLS case report in a household with two consanguineously married parents was provided. A 17-year-old Saudi boy visited the dental clinic at Riyadh Elm University because he was having problems with loose teeth and pain while chewing, as well as irritated and friable gums. He may be suffering from a genetic condition that has been effectively treated in the past by his elder brother, who is now 26 years old. In this instance, severe extensive periodontitis contributed to the early loss of primary teeth as well as permanent teeth, resulting in PLS. On the lateral surface of the soles, the distinctive skin lesions revealed hyperkeratosis with regions of persistent thickening, flaking, and scaling. There were erythematous patches on the palms, but no hyperkeratosis was seen. Conclusion: When it comes to Papillon-Lefévre syndrome (PLS), this is an extremely unusual instance since two siblings in the same family were both afflicted. Patients who are stigmatised because of their condition will benefit from early discovery and multidisciplinary treatment.

Abstract
Papillon-Lefèvre Syndrome (PLS) is an autosomal recessive monogenic disease caused by loss-of-function mutations in the CTSC gene, thus preventing the synthesis of the protease Cathepsin C (CTSC) in a proteolytically active form. CTSC is responsible for the activation of the pro-forms of the neutrophil serine proteases (NSPs; Elastase, Proteinase 3 and Cathepsin G), suggesting its involvement in a variety of neutrophil functions. In PLS neutrophils, the lack of CTSC protease activity leads to inactivity of the NSPs. Clinically, PLS is characterized by an early, typically pre-pubertal, onset of severe periodontal pathology and palmoplantar hyperkeratosis. However, PLS is not considered an immune deficiency as patients do not typically suffer from recurrent and severe (bacterial and fungal) infections. In this study we investigated an unusual CTSC mutation in two siblings with PLS, a 503A>G substitution in exon 4 of the CTSC gene, expected to result in an amino acid replacement from tyrosine to cysteine at position 168 of the CTSC protein. Both patients bearing this mutation presented with pronounced periodontal pathology. The characteristics and functions of neutrophils from patients homozygous for the 503A>G CTSC mutation were compared to another previously described PLS mutation (755A>T), and a small cohort of healthy volunteers. Neutrophil lysates from patients with the 503A>G substitution lacked CTSC protein and did not display any CTSC or NSP activity, yet neutrophil counts, morphology, priming, chemotaxis, radical production, and regulation of apoptosis were without any overt signs of alteration. However, NET formation upon PMA-stimulation was found to be severely depressed, but not abolished, in PLS neutrophils.

Abstract
Epidemiological studies established an association between chronic inflammation and higher risk of cancer. Inhibition of proteolytic enzymes represents a potential treatment strategy for cancer and prevention of cancer metastasis. Cathepsin C (CatC) is a highly conserved lysosomal cysteine dipeptidyl aminopeptidase required for the activation of pro-inflammatory neutrophil serine proteases (NSPs, elastase, proteinase 3, cathepsin G and NSP-4). NSPs are locally released by activated neutrophils in response to pathogens and non-infectious danger signals. Activated neutrophils also release neutrophil extracellular traps (NETs) that are decorated with several neutrophil proteins, including NSPs. NSPs are not only NETs constituents but also play a role in NET formation and release. Although immune cells harbor large amounts of CatC, additional cell sources for this protease exists. Upregulation of CatC expression was observed in different tissues during carcinogenesis and correlated with metastasis and poor patient survival. Recent mechanistic studies indicated an important interaction of tumor-associated CatC, NSPs, and NETs in cancer development and metastasis and suggested CatC as a therapeutic target in a several cancer types. Cancer cell-derived CatC promotes neutrophil recruitment in the inflammatory tumor microenvironment. Because the clinical consequences of genetic CatC deficiency in humans resulting in the elimination of NSPs are mild, small molecule inhibitors of CatC are assumed as safe drugs to reduce the NSP burden. Brensocatib, a nitrile CatC inhibitor is currently tested in a phase 3 clinical trial as a novel anti-inflammatory therapy for patients with bronchiectasis. However, recently developed CatC inhibitors possibly have protective effects beyond inflammation. In this review, we describe the pathophysiological function of CatC and discuss molecular mechanisms substantiating pharmacological CatC inhibition as a potential strategy for cancer treatment.

Abstract
Cysteine cathepsin C (CatC) is a ubiquitously expressed, lysosomal aminopeptidase involved in the activation of zymogens of immune-cell-associated serine proteinases (elastase, cathepsin G, proteinase 3, neutrophil serine proteinase 4, lymphocyte granzymes, and mast cell chymases). CatC is first synthetized as an inactive zymogen containing an intramolecular chain propeptide, the dimeric form of which is processed into the mature tetrameric form by proteolytic cleavages. A molecular modeling analysis of proCatC indicated that its propeptide displayed a similar fold to those of other lysosomal cysteine cathepsins, and could be involved in dimer formation. Our in vitro experiments revealed that human proCatC was processed and activated by CatF, CatK, and CatV in two consecutive steps of maturation, as reported for CatL and CatS previously. The unique positioning of the propeptide domains in the proCatC dimer complex allows this order of cleavages to be understood. The missense mutation Leu172Pro within the propeptide region associated with the Papillon-Lefèvre and Haim-Munk syndrome altered the proform stability as well as the maturation of the recombinant Leu172Pro proform.

Abstract
OBJECTIVES To identify the molecular basis of Papillon-Lefèvre syndrome in two Chinese families. METHODS Peripheral blood and mouth swab samples were obtained, from which genomic DNA and RNA were isolated. Sanger sequencing was employed to identify the mutations. mRNA expression was tested by real-time quantitative PCR. Evolutionary conservation, pathogenicity prediction and impact of protein structures of the mutations were conducted with bioinformatics tools and homology modelling. HEK293 cells were transfected with plasmids expressing wild-type or mutated CTSC. CTSC protein expression level and enzyme activity were explored. RESULTS Mutation analysis revealed two novel compound heterozygous mutations, the c.190-191insA and c.1211-1212delA in patient 1 and the c.716A>G and c.757+1G>A in patient 2. In both patients, the levels of CTSC mRNA were significantly lower than in their relatives. Homology modelling analysis predicted that the mutations affect the structure and stability of the protein, and in vitro study showed that the CTSC proteins containing the mutations c.190-191insA and c.1211-1212delA, which result in truncated versions of protein, display impaired enzyme activity. The protein containing c.716A>G mutation showed quite similar enzyme activity compared to wild-type CTSC. CONCLUSION Our data support the molecular mechanism of PLS and enlarge the scope of CTSC gene mutations related to PLS.

Abstract
Membrane-bound proteinase 3 (PR3m) is the main target antigen of anti-neutrophil cytoplasmic autoantibodies (ANCA) in granulomatosis with polyangiitis, a systemic small-vessel vasculitis. Binding of ANCA to PR3m triggers neutrophil activation with the secretion of enzymatically active PR3 and related neutrophil serine proteases, thereby contributing to vascular damage. PR3 and related proteases are activated from pro-forms by the lysosomal cysteine protease cathepsin C (CatC) during neutrophil maturation. We hypothesized that pharmacological inhibition of CatC provides an effective measure to reduce PR3m and therefore has implications as a novel therapeutic approach in granulomatosis with polyangiitis. We first studied neutrophilic PR3 from 24 patients with Papillon-Lefèvre syndrome (PLS), a genetic form of CatC deficiency. PLS neutrophil lysates showed a largely reduced but still detectable (0.5-4%) PR3 activity when compared with healthy control cells. Despite extremely low levels of cellular PR3, the amount of constitutive PR3m expressed on the surface of quiescent neutrophils and the typical bimodal membrane distribution pattern were similar to what was observed in healthy neutrophils. However, following cell activation, there was no significant increase in the total amount of PR3m on PLS neutrophils, whereas the total amount of PR3m on healthy neutrophils was significantly increased. We then explored the effect of pharmacological CatC inhibition on PR3 stability in normal neutrophils using a potent cell-permeable CatC inhibitor and a CD34+ hematopoietic stem cell model. Human CD34+ hematopoietic stem cells were treated with the inhibitor during neutrophil differentiation over 10 days. We observed strong reductions in PR3m, cellular PR3 protein, and proteolytic PR3 activity, whereas neutrophil differentiation was not compromised.
