Abstract
OBJECTIVE Juvenile localized scleroderma (LS) is an autoimmune disease of the skin whose pathogenesis is not well understood due to the rarity of the disease. This study was undertaken to determine the skin transcriptome in skin biopsy tissue from children with juvenile LS compared to pediatric healthy controls, with identification of significant molecular targets using RNA sequencing (RNA-Seq). In this study, differentially expressed genes (DEGs) were assessed for correlations with histopathologic and clinical features in children with juvenile LS, and were used to group the children into distinct genetic clusters based on immunophenotype. METHODS RNA-Seq was performed on sections of paraffin-embedded skin tissue obtained from 28 children with juvenile LS and 10 pediatric healthy controls. RNA-Seq was carried out using an Illumina HTS TruSeq RNA Access library prep kit, with data aligned using STAR and data analysis using a DESeq2 platform. A standardized histologic scoring system was used to score skin sections for the severity of inflammation and levels of collagen deposition. Histologic scoring was completed by 2 pathologists who were blinded with regard to the status of each sample. Spearman's rank correlation coefficients were used to assess significant correlations between DEG expression profiles and skin histologic findings in patients with juvenile LS. RESULTS We identified 589 significant DEGs in children with juvenile LS as compared to healthy controls. Hierarchical clustering was used to demonstrate 3 distinct juvenile LS immunophenotype clusters. The histologic scores of skin inflammation (based on numbers and categories of inflammatory cell infiltrates) were significantly correlated with the expression levels of HLA-DPB1, HLA-DQA2, HLA-DRA, and STAT1 genes (rs > 0.5, P < 0.01). Collagen thickness correlated with the expression levels of collagen organization genes as well as with genes found to be correlated with the severity of inflammation, including genes for major histocompatibility complex (MHC) class I, MHC class II, and interferon-γ signaling. CONCLUSION Among children with juvenile LS, 3 distinct genetic signatures, or clusters, were identified. In one cluster, inflammation-related pathways were up-regulated, corresponding to the histologic skin inflammation score. In the second cluster, fibrosis-related pathways were up-regulated. In the third cluster, gene expression in the skin corresponded to the patterns seen in healthy controls. Up-regulation of HLA class II genes was observed within the first cluster (characterized by predominant inflammation), a feature that has also been observed in the peripheral blood of patients with morphea and in the skin of patients with systemic sclerosis.

Pathological pulmonary vascular remodeling is induced by type V collagen in a model of scleroderma. Pathol Res Pract 2021; 220:153382. [PMID: 33647866 DOI: 10.1016/j.prp.2021.153382] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Revised: 02/10/2021] [Accepted: 02/12/2021] [Indexed: 10/22/2022]
Abstract
OBJECTIVE The pulmonary vascular remodeling in systemic sclerosis (SSc) is poorly understood and animal models are lacking. Type V collagen (COLV) is elevated in SSc and is implicated in the pathogenesis, and immunization with human COLV induces SSc-like skin and lung changes in rabbits and mice. Here we tested the hypothesis that COLV immunization will induce pathological and functional changes that phenocopy SSc-associated pulmonary vascular disease. METHODS Pulmonary vascular changes in rabbits immunized with human COLV were extensively characterized by a combination of histology, electron microscopy and immunohistochemistry. Physiologic changes induced by COLV in explanted pulmonary artery rings were evaluated. The pattern of histopathologic alterations and gene expression induced in immunized rabbits were compared to those in SSc patients. RESULTS COLV immunization was accompanied by striking pulmonary vascular abnormalities, characterized by reduced capillary density, perivascular inflammation, endothelial cell injury and collagen accumulation, that closely phenocopy changes seen in SSc patients. Moreover, pulmonary arteries from immunized rabbits showed impaired ex vivo vascular relaxation. Expression of COL5A2 was significantly increased in the lungs from immunized rabbits (p = 0.02), as well as in patients with SSc (P = 0.02). CONCLUSION COLV immunity in rabbits is associated with marked vascular remodeling in the lung that phenocopies early-stage human SSc-associated pulmonary vascular disease. COLV immunization therefore represents a novel approach to model SSc pulmonary vascular pathology. Moreover, our findings suggest that COLV might represent a novel pathogenic autoantigen in SSc and future studies with the present model should be developed for possible association with PAH.

Abstract
Periodontal ligament (PDL), as a mechanical connection between the alveolar bone and tooth, plays a pivotal role in force-induced orthodontic tooth movement (OTM). However, how mechanical force controls remodeling of PDL collagenous extracellular matrix (ECM) is largely unknown. Here, we aimed to evaluate the stress distribution and ECM fiber remodeling of PDL during the process of OTM. An experimental tooth movement model was built by ligating a coil spring between the left maxillary first molar and the central incisors. After activating the coil spring for 7 days, the distance of tooth movement was 0.324 ± 0.021 mm. The 3D finite element modeling showed that the PDL stress obviously concentrated at cervical margin of five roots and apical area of the mesial root, and the compression region was distributed at whole apical root and cervical margin of the medial side (normal stress < -0.05 MPa). After force induction, the ECM fibers were disordered and immature collagen III fibers significantly increased, especially in the apical region, which corresponds to the stress concentration and compression area. Furthermore, the osteoclasts and interleukin-1β expression were dramatically increased in the apical region of the force group. Taken together, orthodontic loading could change the stress distribution of PDL and induce a disordered arrangement and remodeling of ECM fibers. These findings provide orthodontists both mechanical and biological evidences that root resorption is prone to occur in the apical area during the process of OTM.

Abstract
OBJECTIVE To evaluate the frequency of anti-collagen type V in humans with early systemic sclerosis (SSc) compared to defined SSc patients and healthy controls, since collagen type V was shown to be overexpressed in early SSc patients' skin and there is no data concerning the presence of this antibody in early stages of human SSc. Experimental studies showed that animal models immunized with collagen type V developed a disease similar to human systemic sclerosis (SSc), with antibodies production, mainly in early stages post-immunization. METHODS Eighty-one female SSc patients were included and divided into two groups: early-SSc (18 patients-EULAR Preliminary Criteria) and defined-SSc (63 patients-ACR Criteria 1980). The control group consisted of 19 healthy women age-matched to Early-SSc group. Anti-collagen type V was performed by ELISA. Data was analyzed by appropriate tests. RESULTS The prevalence of anti-collagen type V in early-SSc, defined-SSc and control groups was respectively 33, 17 and 5% (p = 0.07). SSc patients with anti-collagen type V had shorter disease duration compared to those without this antibody (8.8 ± 5.1 vs. 14.7 ± 8.9, p = 0.006). Likewise, early-SSc patients with anti-collagen V also had a shorter disease duration than patients negative for this antibody (4.6 ± 2.2 vs. 9.7 ± 5.2, p = 0.04). No association with clinical subsets or scleroderma antibodies specificities was observed (p > 0.05). CONCLUSION The production of anti-collagen type V in SSc seems to be an early event independent of other antibodies specificities. Further studies are necessary to determine if the underlying mechanism for this chronology involves a primary immune response to abnormal expression of collagen type V.

Abstract
Limitations on tissue proliferation capacity determined by telomerase/apoptosis
balance have been implicated in pathogenesis of idiopathic pulmonary fibrosis. In
addition, collagen V shows promise as an inductor of apoptosis. We evaluated the
quantitative relationship between the telomerase/apoptosis index, collagen V
synthesis, and epithelial/fibroblast replication in mice exposed to butylated
hydroxytoluene (BHT) at high oxygen concentration. Two groups of mice were analyzed:
20 mice received BHT, and 10 control mice received corn oil. Telomerase expression,
apoptosis, collagen I, III, and V fibers, and hydroxyproline were evaluated by
immunohistochemistry, in situ detection of apoptosis, electron
microscopy, immunofluorescence, and histomorphometry. Electron microscopy confirmed
the presence of increased alveolar epithelial cells type 1 (AEC1) in apoptosis.
Immunostaining showed increased nuclear expression of telomerase in AEC type 2 (AEC2)
between normal and chronic scarring areas of usual interstitial pneumonia (UIP).
Control lungs and normal areas from UIP lungs showed weak green birefringence of type
I and III collagens in the alveolar wall and type V collagen in the basement membrane
of alveolar capillaries. The increase in collagen V was greater than collagens I and
III in scarring areas of UIP. A significant direct association was found between
collagen V and AEC2 apoptosis. We concluded that telomerase, collagen V fiber
density, and apoptosis evaluation in experimental UIP offers the potential to control
reepithelization of alveolar septa and fibroblast proliferation. Strategies aimed at
preventing high rates of collagen V synthesis, or local responses to high rates of
cell apoptosis, may have a significant impact in pulmonary fibrosis.

Abstract
OBJECTIVE The physiological and mechanical properties of the skin, the primary tissue affected by systemic sclerosis, depend on the assembly of collagen types I, III and V, which form heterotypic fibers. Collagen V (COLV) regulates heterotypic fiber diameter, and the maintenance of its properties is important for maintaining normal tissue architecture and function. Based on a COLV-induced experimental SSc model, in which overexpression of abnormal COLV was a prominent feature, we assumed that this abnormality could be present in SSc patients and could be correlated to disease duration, skin thickening and disease activity. METHODS Skin biopsies from 18 patients (6 early-stage and 12 late-stage) and 10 healthy controls were studied. Skin thickening assessment was performed with the Modified Rodnan Skin Score (MRSS), and activity was calculated using the Valentini Disease Activity Index. Morphology, morphometry of COLV deposition in dermis, as well as, quantitative RT-PCR and 3D-reconstruction of the dermal fibroblast culture were performed. RESULTS Structurally abnormal COLV was overexpressed in SSc skin, mainly in the early stages of the disease, when compared to normal controls and late-stage. A positive correlation between COLV expression and MRSS and disease activity was observed. Collagen V alpha-1 and alpha-2 mRNA expression levels were higher in SSc. Tridimensional reconstruction of SSc dermal heterotypic fibers confirmed the presence of atypical COLV. CONCLUSION Increased synthesis of abnormal COLV and its correlation with disease stage, activity and MRSS suggest that this collagen can be a possible trigger involved in the pathogenesis of SSc.

Abstract
BACKGROUND Impaired healing is a problematic and common complication of chronic wounds. Although pulsed radiofrequency energy has been used in the treatment of chronic wounds with promising efficacy, its mechanism is still poorly characterized. In this study, the authors used a diabetic mouse model to illustrate the action of pulsed radiofrequency energy on cutaneous wounds and set the stage to begin to understand its mechanism. METHODS Full-thickness cutaneous wounds were created in diabetic mice (n = 26). The experimental group (n = 13) was subject to pulsed radiofrequency energy treatment two times per day, whereas the sham group (n = 13) was subjected to sham devices. The rate of wound closure was evaluated by digital analysis of surface area of the wound bed, zone of reepithelialization, and rate of contraction. Mice were euthanized on days 7, 10, 22, and 42 and wounds were evaluated qualitatively and quantitatively by hematoxylin and eosin, Masson's trichrome, and Ki-67 assay for cell proliferation. RESULTS In the experimental group, the rate of wound closure was significantly accelerated, particularly beyond day 17. Contraction contributed to the wound healing process rather than reepithelialization. This was also associated with increased granulation tissue that was most prominent by day 22 and with enhanced dermal cell proliferation, with 25 percent and 45 percent Ki-67-positive nuclei on days 10 and 22, respectively, as compared with control animals. CONCLUSION These results indicate that pulsed radiofrequency energy accelerates impaired wound healing mainly through wound contraction by means of stimulating cell proliferation, granulation tissue formation, and collagen deposition.
