Abstract
Fibrin is the provisional matrix formed after injury, setting the trajectory for the subsequent stages of wound healing. It is commonly used as a wound sealant and a natural hydrogel for three-dimensional (3D) biophysical studies. However, the traditional thrombin-driven fibrin systems are poorly controlled. Therefore, the precise roles of fibrin's biophysical properties on fibroblast functions, which underlie healing outcomes, are unknown. Here, we establish a snake venom-controlled fibrin system with precisely and independently tuned architectural and mechanical properties. Employing this defined system, we show that fibrin architecture influences fibroblast survival, spreading phenotype, and differentiation. A fine fibrin architecture is a key prerequisite for fibroblast differentiation, while a coarse architecture induces cell loss and disengages fibroblast's sensitivity towards TGF-β1. Our results demonstrate that snake venom-controlled fibrin can precisely control fibroblast differentiation. Applying these biophysical principles to fibrin sealants has translational significance in regenerative medicine and tissue engineering.

Abstract
Introduction The formation of diabetic ulcers (DU) is a common complication for diabetic patients resulting in serious chronic wounds. There is therefore, an urgent need for complex treatment of this problem. This study examines a bioactive wound dressing of a biodegradable electrospun nanofibrous blend of poly(L-lactide-co-ε-caprolactone) and poly(ε-caprolactone) (PLCL/PCL) covered by a thin fibrin layer for sustained delivery of bioactive molecules. Methods Electrospun PLCL/PCL nanofibers were coated with fibrin-based coating prepared by a controlled technique and enriched with human platelet lysate (hPL), fibroblast growth factor 2 (FGF), and vascular endothelial growth factor (VEGF). The coating was characterized by scanning electron microscopy and fluorescent microscopy. Protein content and its release rate and the effect on human saphenous vein endothelial cells (HSVEC) were evaluated. Results The highest protein amount is achieved by the coating of PLCL/PCL with a fibrin mesh containing 20% v/v hPL (NF20). The fibrin coating serves as an excellent scaffold to accumulate bioactive molecules from hPL such as PDGF-BB, fibronectin (Fn), and α-2 antiplasmin. The NF20 coating shows both fast and a sustained release of the attached bioactive molecules (Fn, VEGF, FGF). The dressing significantly increases the viability of human saphenous vein endothelial cells (HSVECs) cultivated on a collagen-based wound model. The exogenous addition of FGF and VEGF during the coating procedure further increases the HSVECs viability. In addition, the presence of α-2 antiplasmin significantly stabilizes the fibrin mesh and prevents its cleavage by plasmin. Discussion The NF20 coating supplemented with FGF and VEGF provides a promising wound dressing for the complex treatment of DU. The incorporation of various bioactive molecules from hPL and growth factors has great potential to support the healing processes by providing appropriate stimuli in the chronic wound.

Identification of substrates of MBL Associated Serine Protease-1 (MASP-1) from human plasma using N-terminomics strategy. Mol Immunol 2022; 151:114-125. [PMID: 36126499 DOI: 10.1016/j.molimm.2022.09.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Revised: 08/23/2022] [Accepted: 09/04/2022] [Indexed: 11/23/2022]
Abstract
MBL Associated Serine Protease-1 (MASP-1) is an abundant enzyme of the lectin complement pathway. MASP-1 cleaves numerous substrates like MASP-2, MASP-3, C2, C3i, fibrinogen, FXIII and prothrombin. It has thrombin-like specificity and can cleave thrombin substrates. Owing to its high concentration and relaxed substrate specificity, MASP-1 has substrates outside the complement system and can influence other proteolytic cascades and physiological processes. The unidentified substrates may assist us to ascertain the role(s) of MASP-1. In this study, we used a high-throughput N-terminomics method to identify substrates of MASP-1 from human plasma. We have identified 35 putative substrates of MASP-1. Among the identified proteins, alpha 2-antiplasmin, alpha-1-acid glycoprotein, antithrombin III, and siglec-6 were demonstrated to be cleaved by MASP-1. We have discussed the physiological relevance of cleavage of these substrates by MASP-1. The expression of Siglec-6 and MASP-1 has been reported in the B cells. Alpha-1-acid glycoprotein cleavage by MASP-1 may occur in the acute phase as it is known to be an inhibitor of platelet aggregation, whereas MASP-1 triggers platelet aggregation. The cleavage alpha2 antiplasmin by MASP-1 implies that MASP-1 may be promoting plasmin-mediated fibrinolysis. Our study supports that MASP-1 may be implicated in thrombosis as well as thrombolysis.

Abstract
Skin injury is followed by accumulation of a fibrin based provisional matrix which normally drives the process of wound repair. Exogenous fibrin with extra cellular matrix (ECM) components can also favor the wound healing process. In a preliminary study we found that lyophilized fibrin sheet (FS) arrest bleeding from rabbit skin wound but it remained dry during the repair period and did not accelerate the healing process better than untreated control. In the current study, hyaluronic acid (HA) was incorporated into FS and the resultant HA-FS promoted water retention and improved wound healing process. Gross-morphology, histopathology and histomorphometry were employed to compare qualitative and quantitative difference of wound healing in treated group against controls. In experimental sites (HA-FS), re-epithelialization was completed by 14 days with neo-vascularization and deposition of wavy bundles of collagen in the treated sites. Rate of healing process was different in treated and untreated wounds and most striking difference was the appearance of appendages, sebaceous gland and hair follicle at some locations in HA-FS treated sites. Therefore, HA with fibrin can create an effective wound care matrix which promotes water retention and wound healing potential.

Abstract
Candida albicans expresses at least two biochemically distinct fibronectin receptors. Hemoglobin induces expression of a low affinity receptor recognizing the fibronectin cell-binding domain, whereas growth in complex media induces a high affinity receptor recognizing the collagen-binding domain. We now show that sub-inhibitory concentrations of caspofungin and nikkomycin Z, but not fluconazole, induce the high affinity fibronectin receptor in a dose-dependent manner. Macromolecular complexes mechanically sheared from caspofungin-treated cells retained high affinity fibronectin binding that was sensitive to protease, disulfide reduction, and beta (1,3) glucanase digestion. The high affinity fibronectin receptor was not inducible in a Kre9 mutant strain of C. albicans deficient in beta (1,6) glucans. Conversely, a mutant strain lacking the fibronectin binding protein Als5p showed no defects in induction of high or low affinity fibronectin receptors. Heterozygous mutants of a regulator of white-opaque phenotypic switching, HBR1, lacked any detectable high affinity fibronectin receptor expression in response to caspofungin, and re-introduction of the gene restored activity. Therefore, sub-inhibitory dosages of caspofungin induce a high affinity fibronectin receptor that is distinct from the known receptor Als5p and is dependent on beta (1,6) glucans and HBR1.

Abstract
After penetration of human or duck host's skin schistosomula of Schistosoma mansoni and Trichobilharzia ocellata migrate parallel to the surface in the epidermis, then they enter the dermis and venules prior to further migration. This study focuses on potential behavioural mechanisms and host cues which may enable this navigation within host tissues. We stimulated cercariae to penetrate into agar substrates and to transform to schistosomula, and analysed their orientation behaviour within chemical concentration gradients. Both species were chemotactically attracted by low molecular weight fractions of their host's serum (human, duck) and D-glucose and L-arginine were identified as attractive components in serum. They responded to gradients, which established after addition of very low concentrations of D-glucose (1 microM in T. ocellata and 2 microM in S. mansoni) and L-arginine (0.025 microM in T. ocellata and 1.0 microM in S. mansoni). The response to D-glucose was specific as other saccharides had no stimulatory activity. L-Arginine stimulated chemotactic orientation both when free and bound in peptides. However, the two species responded differently to the position of L-arginine within the peptide (terminal or subterminal), and only S. mansoni, not T. ocellata, responded to peptides occurring in serum and endothelial cells: fibronectin (1 microM), bradykinin (25 pM) and its fragment 1-5 (2.5 microM). Both species adjusted their body axis with the ventral side towards the higher concentrations of D-glucose and of L-arginine. We argue that the chemotactic orientation and the alignment of the body axis enable the parasites (i) to orientate towards deeper skin layers and avoid accidental perforation of the covering skin surface layers, (ii) to determine their position during their surface-parallel migration within the epidermis, (iii) to locate blood vessels.

Abstract
A randomized study of 30 patients undergoing uncomplicated surgery under spinal anesthesia was conducted to assess the influence of colloids on the kinetics of plasma fibronectin and complement. Both are opsonins of the reticuloendothelial system; moreover fibronectin is concerned with host resistance against septic complications following trauma and surgery. The patients were assigned to receive either Ringer's lactate (Group 1), gelatin (Group 2) or dextran 40 (Group 3). Blood samples were withdrawn before colloids or Ringer's infusion and during the 4 postoperative days. There was a reduction in plasma fibronectin throughout the study in groups 1 and 3, but an increase in group 2 by 24 h. The adhesion of plasma fibronectin to gelatin was maximal 1 h after infusion (44%) and remained significant up to day 2 in group 2. There was no relationship in groups 1 and 3. C3 and C4 components of complement exhibited a low value in the early post-operative period, due to hemodilution. This study shows an in vivo fibronectin-gelatin interaction, and suggests that gelatin infusion inhibits the increased shift of plasma fibronectin at the site of tissue injury after surgery.
