Abstract
Hypertrophic scar (HS) and keloid are fibroproliferative disorders (FPDs) of the skin due to aberrant wound healing, which cause disfigured appearance, discomfort, dysfunction, psychological stress, and patient frustration. The unclear pathogenesis behind HS and keloid is partially responsible for the clinical treatment stagnancy. However, there are now increasing evidences suggesting that inflammation is the initiator of HS and keloid formation. Interleukins are known to participate in inflammatory and immune responses, and play a critical role in wound healing and scar formation. In this review, we summarize the function of related interleukins, and focus on their potentials as the therapeutic target for the treatment of HS and keloid.

Abstract
Hypertrophic scars (HS) arise from traumatic or surgical injuries and the subsequent abnormal wound healing, which is characterized by continuous and histologically localized inflammation. Therefore, inhibiting local inflammation is an effective method of treating HS. Recent insight into the role of interleukin-10 (IL-10), an important anti-inflammatory cytokine, in fibrosis has increased our understanding of the pathophysiology of HS and has suggested new therapeutic targets. This review summarizes the recent progress in elucidating the role of IL-10 in the formation of HS and its therapeutic potential based on current research. This knowledge will enhance our understanding of the role of IL-10 in scar formation and shed new light on the regulation and potential treatment of HS.

Abstract
Various protocols for recombinant Interleukin-10 (IL-10) purification in wound healing have been reported previously. However, the therapeutic effect was not obvious. Thus, it is of great importance to find new and effective approaches for therapy. In this study, we propose that IL-10 and Arginine-Glycine-Aspartic (RGD) peptide would be a valuable therapeutic for wound healing. To explore a high-efficiency and cost-effective approach for the production of IL-10 and RGD peptide with bioactivity, a synthetic gene was cloned into a recombinant pTWIN1 vector. As a consequence, rhIL-10-RGD and the pH-induced self-cleavable Ssp DnaB mini-intein as a fusion protein was highly expressed by IPTG induction in Escherichia coli Rosetta without extra residues in a bioreactor. After Ni affinity chromatographic purification, rhIL-10-RGD was released by the Ssp DnaB intein-mediated self-cleavage that is triggered by pH shift. SDS-PAGE and silver staining showed a major band with an estimated molecular mass of 19.3kDa. Cell proliferation assay confirmed its potent proliferation activity on MC/9 murine mast cells. In conclusion, we report a novel strategy to produce rhIL-10-RGD mediated by the pH-induced self-cleavable Ssp DnaB mini-intein, and show that rhIL-10-RGD could play an effective role in wound healing of BALB/c mice.

Abstract
Hypertrophic scars (HTS) are caused by dermal injuries such as trauma and burns to the deep dermis, which are red, raised, itchy and painful. They can cause cosmetic disfigurement or contractures if craniofacial areas or mobile region of the skin are affected. Abnormal wound healing with more extracellular matrix deposition than degradation will result in HTS formation. This review will introduce the physiology of wound healing, dermal HTS formation, treatment and difference with keloids in the skin, and it also review the current advance of molecular basis of HTS including the involvement of cytokines, growth factors, and macrophages via chemokine pathway, to bring insights for future prevention and treatment of HTS.

Abstract
This study aimed to use a mouse model of hypertrophic scarring by mechanical loading on the dorsum of mice to determine whether the nervous system of the skin and inflammation participates in hypertrophic scarring. Results of hematoxylin-eosin and immunohistochemical staining demonstrated that inflammation contributed to the formation of a hypertrophic scar and increased the nerve density in scar tissue.Western blot assay verified that interleukin-13 expression was increased in scar tissue. These findings suggest that inflammation and the cutaneous nervous system play a role in hypertrophic scar formation.

Abstract
This study aimed to explore the role of mechanical tension in hypertrophic scars and the change in nerve density using hematoxylin-eosin staining and S100 immunohistochemistry, and to observe the expression of nerve growth factor by western blot analysis. The results demonstrated that mechanical tension contributed to the formation of a hyperplastic scar in the back skin of rats, in conjunction with increases in both nerve density and nerve growth factor expression in the scar tissue. These experimental findings indicate that the cutaneous nervous system plays a role in hypertrophic scar formation caused by mechanical tension.

Abstract
Pain accompanies every disruption of the skin surface in a normal sensate individual. The intensity and duration of the pain varies depending on the nature of trauma, the healing trajectory and various host factors. Pain mediator release is the mechanism for pain perception following peripheral stimulus and central interpretation. The various mediators may have promoting effects on wound healing in the short term, but it appears that protracted release of these mediators may well have detrimental effects on wound healing. The exaggerated release of pain mediators may result in nociceptor hypersensitization, hyperinflammatory cellular and extracellular matrix (ECM) changes, and in some cases, the potential for a fibrotic healing pattern. This relates to an imbalance between mediators with differing healing characteristics arising in certain pathological conditions. In this respect, it may be worth examining pain mediator agonists or antagonists, not only on compassionate grounds of pain control, but relating to the potential effects on overall wound healing.

Henderson J, Ferguson MWJ, Terenghi G. The reinnervation pattern of wounds and scars after treatment with transforming growth factor β isoforms. J Plast Reconstr Aesthet Surg 2012; 65:e80-6.

Abstract
BACKGROUND Wounds deprived of innervation fail to heal normally, and hypertrophic scars may be abnormally innervated. Manipulation of wounds alters the subsequent degree of scarring, and isoforms of transforming growth factor beta (TGFβ) are well established in this role, whilst TGFβ3 is undergoing clinical trials as an antiscarring agent for clinical use. It is unclear if treated wounds show changes in their innervation patterns as they mature into scars. METHODS Mice underwent 1cm(2) full thickness skin excisions which were treated with TGFβ1 or TGFβ3. Wounds were harvested between 5 and 84 days (n=6 at each time point). Sections underwent histological scar assessment and immunohistochemical staining for protein gene product 9.5 (PGP9.5), a pan-neuronal marker, and the sensory neuropeptides calcitonin gene related peptide (CGRP) and substance P (SP). RESULTS There was no difference in the reinnervation pattern between the peripheral and central parts of the wounds. Wounds treated with TGFβ3 healed with dermal collagen organised more like normal skin, whereas TGFβ1 treated wounds had abnormally orientated collagen within the scar compared to control treated wounds. Nerve fibre growth into the wounds followed a similar pattern in control and treated wounds, with only one significant difference during the healing process- at 42 days, the density of nerve fibres immunostained with PGP9.5 within the scar was greater than in control wounds. By 84 days, the density of PGP9.5, CGRP and SP immunopositive fibres were similar in control wounds and those treated with TGFβ isoforms. CONCLUSIONS Changes in reinnervation patterns of wounds treated with TGFβ isoforms were only slightly different from those of control wounds, and by 84 days, the patterns were similar.
