TREM2-mediated Macrophage Glycolysis Promotes Skin Wound Angiogenesis via the Akt/mTOR/HIF-1α Signaling Axis.

Objective: The trigger receptor expressed on myeloid cells-2 (TREM2) pathway in myeloid cells is a key disease-inducing immune signaling hub that is essential for detecting tissue damage and limiting its pathological spread. However, the role and potential mechanisms of TREM2 in wound repair remain unclear. The purpose of this study was to determine the role and mechanism of TREM2 in skin wound healing in mice.

A cross-sectional study of clinical characteristics and risk factors for hand eczema in the general Chinese population.

In the general population, there is limited evidence for the associations between hand eczema (HE) and lifestyle factors, and between the severity of HE and quality of life. This study aimed to estimate the risk factors for the incidence of HE in the general population and the risk factors for the severity of HE. A cross-sectional questionnaire was administered to 121 HE patients in a hospital from December 2018 to December 2019 in Wuhan.

Defactinib inhibits FAK phosphorylation and regulates psoriasis via attenuating hyperproliferation of keratinocytes.

Excessive proliferation of keratinocytes is a crucial pathological risk feature of psoriasis. Focal adhesion kinase (FAK) is a non-receptor protein that primarily regulates cell proliferation and migration. However, the expression and regulatory mechanism of FAK in psoriasis remains unclear.

Reflectance confocal microscopy for plaque psoriasis therapeutic follow-up during an anti-interleukin-17A monoclonal antibody: an observational study.

Interleukin-17A therapeutic inhibitors are among the most effective treatment methods for moderate-to-severe plaque psoriasis (PP). Reflectance confocal microscopy is a non-invasive imaging technique already documented to be beneficial in evaluating the follow-up of PP under treatment with topical actives and phototherapy. This study aimed to assess the epidermal and dermal changes associated with psoriasis and its treatment with RCM during systemic secukinumab treatment in patients with moderate-to-severe PP.

Successful treatment of Giant keloid on the right toes using trepanation combined with superficial radiotherapy (SRT-100): a case report with literature review.

In dermatology, a keloid is one of the most common skin morphological abnormalities caused by excessive proliferation of fibroblasts. Keloids that are large or occur near important joint sites often cause varying degrees of physiological dysfunction in patients, therefore requiring medical treatment. A boy with congenital syndactyly developed huge keloids at the surgical site after undergoing surgical correction treatment.

ALA-PDT promotes the death and contractile capacity of hypertrophic scar fibroblasts through inhibiting the TGF-β1/Smad2/3/4 signaling pathway.

Background: Hypertrophic scars, an abnormal wound-healing response to burn injuries, are characterized by massive fibroblast proliferation and excessive deposition of extracellular matrix and collagen. 5-aminolevulinic acid-based photodynamic therapy (ALA-PDT) is a promising therapy for hypertrophic scar, details of the mechanisms remain to be elucidated. In this study, we aimed to investigate the molecular mechanisms involved in ALA-PDT against hypertrophic scar fibroblasts.

Lipoxin A4 Ameliorates Imiquimod-Induced Psoriasis-Like Dermatitis via Promoting the Regression of Inflammation.

Introduction: As a mediator of inflammation resolution, lipoxin A4 (LXA4) mainly plays an anti-inflammatory role and promotes inflammation resolution. LXA4 plays an inhibiting inflammatory role in a variety of diseases, tissues and cells, including keratinocytes. Psoriasis is a chronic inflammatory skin disease mediated by dysregulation of inflammation of immune cells and keratinocytes.

Comparing four immunosuppressive agents for chronic spontaneous urticaria-A network meta-analysis.

Background: Immunosuppression is an integral part of treating chronic spontaneous urticaria (CSU), but there is no literature to evaluate the efficacy of multiple immunosuppressive agents.

Objective: The comparison of the efficacy, safety, and incidence of adverse effects of four immunosuppressive medicines (tripterygium glycosides, methotrexate, cyclosporine A, and azathioprine) in combination with antihistamines in treating CSU provides a clinical reference and evidence-based medicine for treating CSU.

Methods: PUBMED, The Cochrane Library, EMBASE, WANFANG, CNKI, CBM, and clinical trial registration platform were searched to collect relevant randomized controlled trials (RCT) and cohort studies of four immunosuppressive medicines combined with antihistamines for treating CSU.

Epidemiology and Aetiology of Tinea Capitis in Wuhan and Its Surrounding Areas from 2011 Till the Present: A Single-Center Retrospective Study.

Tinea capitis is still common in Wuhan, and there exists significant difference in its pathogen spectrum between this area and other parts of China. In the present study, we aimed to clarify the epidemiological characteristics of tinea capitis and changes of pathogen spectrum in Wuhan and its surrounding areas from 2011 to 2022, and further to present potential risk factors focusing on some major etiological agents. Briefly, a retrospective single-center survey was performed on 778 patients with tinea capitis from 2011 to 2022 in Wuhan, China.

Lnc-EST12, which is negatively regulated by mycobacterial EST12, suppresses antimycobacterial innate immunity through its interaction with FUBP3.

Long noncoding RNAs (lncRNAs) have been implicated in the pathogenesis of intracellular pathogens. However, the role and mechanism of the important lncRNAs in Mycobacterium tuberculosis (M.tb) infection remain largely unexplored.

Mycobacterial EST12 activates a RACK1-NLRP3-gasdermin D pyroptosis-IL-1β immune pathway.

Pyroptosis, an inflammatory form of programmed cell death, has been implicated in eliminating pathogenic infections. However, macrophage pyroptosis-related proteins from () have largely gone unexplored. Here, we identified a cell pyroptosis-inducing protein, Rv1579c, named EST12, secreted from the H37Rv region of difference 3.

Mycobacterium tuberculosis Mannose-Capped Lipoarabinomannan Induces IL-10-Producing B Cells and Hinders CD4Th1 Immunity.

The importance of Th1/interferon (IFN)-γ-mediated responses in mycobacterial infection has been well established. However, little is known about B cell-mediated immunity during Mycobacterium tuberculosis (Mtb) infection. Interleukin (IL)-10-producing B cells (B10 cells), a subset of B regulatory cells (Bregs), are implicated in modulating the immune response.

Recombinant BCG::Rv2645 elicits enhanced protective immunity compared to BCG in vivo with induced ISGylation-related genes and Th1 and Th17 responses.

There is a need to develop protective vaccines against tuberculosis (TB). Recently, we identified an immunodominant T-cell antigen, Rv2645, from the region of deletion 13 (RD13) of M. tuberculosis (M.

Identification of a novel immunodominant antigen Rv2645 from RD13 with potential as a cell-mediated immunity-based TB diagnostic agent.
