These properties confer decellularized extracellular matrix biomaterials a biological advantage over other biomaterials, especially synthetic ones, leading to several successful applications in TERM. While the complex composition of decellularized materials is well known and thought to play a role in providing the regenerative advantage, the fine mechanisms laying behind their bioactivity and immunomodulation were not fully understood yet. In the last decade, researchers have discovered a novel component in decellularized extracellular matrix materials: the matrix bound nanovesicle (MBV). This newly described type of extracellular vesicle is characterized by a tight relation to the extracellular matrix, differently from other liquid phase vesicles, and presents a unique tissue specific cargo, thought to be secreted by cells for specific cell signalling purposes. Although other extracellular vesicles subtypes have been extensively studied in past years, MBVs are different in many ways, making this research field noticeably young. Major bioactivity and immune modulating ability are key features of MBVs that were evident right from the first research works. However, to understand how MBVs can recapitulate and confer decellularized biomaterials with their signature biological performance, they are being characterized in depth. In particular, their rich and varied cargo is being explored, which has shown to play a fundamental role in MBVs’ biological potential. This discovery not only revolutionized the look on decellularized extracellular matrix materials, but it also opened the way for research on a novel type of biomaterial, with plenty potential in therapeutical and regenerative applications.

This review depicts my scientific journey in the field of extracellular matrix biology, and more specifically in collagen research, starting in 1978 and continuing with exciting findings up to the present day. While recounting my early work on the enzymes of collagen biosynthesis, the focus will be on our discoveries of new types of nonfibrillar collagen: type XIII collagen, belonging to the MACIT subgroup among the collagen family of proteins, and types XV and XVIII collagens, constituting the multiplexin subgroup. We have investigated these collagens through molecular biological approaches in order to define their primary structures, and through biochemical and cell biological work to understand their special molecular properties. Furthermore, the generation of many mouse models has led us to exciting studies of the roles of these collagens in adipose tissue, bone, eye, heart, kidney, liver, peripheral nerves, skin, and cancer models, although it has of course also been rather daunting in terms of choosing the correct approach for each tissue. The work on animal models has nevertheless resulted in a broad understanding of the <em>in vivo</em> significance of these collagens, forming a fruitful basis for studying their relevance to human diseases, including malignant processes. Our conclusions have been that these collagens can contribute to the stability of the extracellular matrix and tissue structures, <em>e.g.,</em> the basement membrane and the adjacent fibrillar matrix in the case of the multiplexins and the motor synapse in the case of the MACIT type XIII collagen, and more unexpectedly, that they possess major roles as extrinsic regulators of the fates and functions of cells.</div></div>","PeriodicalId":49851,"journal":{"name":"Matrix Biology","volume":"142 ","pages":"Pages 11-20"},"PeriodicalIF":4.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145226241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, analysis of mouse and human PDA reveal an inextricable link between collagen architecture and the distribution of immunosuppressive macrophages in both early preinvasive disease and invasive carcinomas. <em>In vitro</em> characterization of primary macrophages demonstrates alignment alone is sufficient to induce elongation, polarization, and immunosuppressive activity, including suppression of CD8+ <em>T</em> cell proliferation and motility. Analysis reveals differential focal adhesion kinase (FAK) activity in aligned macrophages, while FAK inhibition (FAKi) disrupts the immunosuppressive phenotype that emerges from encountering ECM alignment. Furthermore, FAKi <em>in vivo</em> significantly reduces the correlation between elongated immunosuppressive macrophages and aligned collagen, further highlighting the opportunity for FAKi to target stromal immunity. Importantly, the correlation between aligned collagen and immunosuppressive macrophages is also observed in human chronic pancreatitis, a known PDA risk factor that has recently been shown to prime stromal ECM alignments for early dissemination, suggesting that precursor disease is also likely to create stromal memory conducive to early immunosuppression.

Indeed, the role of the basement membrane (BM) in adult cardiac disease remains underexplored. We set out to address these knowledge gaps by combining in-depth phenotypic and molecular analyses of a <em>Col4a1</em> mutation on cardiac biology in a murine model (<em>Col4a1<sup>+/svc</sup></em>) of Gould Syndrome. This revealed morphological cardiac defects including cardiomyocyte hypertrophy with myocardial and vascular fibrotic remodelling that impaired cardiac function. The <em>Col4a1</em> mutation causes systolic and diastolic dysfunction with reduced left ventricular developed pressure. Mechanistically, we show these defects are due to secretion of mutant protein and BM defects rather than collagen misfolding and proteotoxic stress. The BM defects lead to a pro-fibrotic state with increased fibrillar collagen deposition, cardiac stiffness, and ECM compositional defects. These are accompanied by altered regulation of pathways involved in sarcomere formation, sarcolemma stability and cardiomyocyte metabolism, establishing a molecular signature of COL4A1-related cardiac disease. Intriguingly, aspects of this molecular signature including cardiac metabolic pathways, regulation of cardiac muscle contraction and BM component expression, are shared with common cardiomyopathies such as coronary micro-embolism, and dilated, ischemic and hypertrophic obstructive cardiomyopathies. By defining the molecular and phenotypic cardiac components of Gould syndrome these data show that the BM is essential for maintaining systolic and diastolic function and that alterations to the BM leads to a fibrotic response.

While humans possess three genes encoding these enzymes (P4H⍺s), <em>Drosophila melanogaster</em> harbour at least 26 candidates for collagen P4H⍺s despite its simple genome, and it is poorly understood which of them are actually working on collagen in the fly. In this study, we addressed this question by carrying out thorough bioinformatic and biochemical analyses. We demonstrate that among the 26 potential collagen P4H⍺s, PH4⍺EFB shares the highest homology with vertebrate collagen P4H⍺s. Furthermore, while collagen P4Hs and their substrates must exist in the same cells, our transcriptomic analyses at the tissue and single cell levels showed a global co-expression of <em>PH4⍺EFB</em> but not the other P4H⍺-related genes with the collagen IV genes. Moreover, expression of <em>PH4⍺EFB</em> during embryogenesis was found to precede that of collagen IV, presumably enabling efficient collagen modification by PH4⍺EFB. Finally, biochemical assays confirm that PH4⍺EFB binds collagen, supporting its direct role in collagen IV modification. Collectively, we identify PH4⍺EFB as the primary and potentially constitutive prolyl 4-hydroxylase responsible for collagen IV biosynthesis in <em>Drosophila</em>.
