Organ fibrosis represents a vital health threat that substantially contributes to yearly mortality rates. While a considerable amount of research has been conducted on fibrosis, these reports have only focused on specific organs as affected within distinct disorders. Accordingly, results from such studies have been unable to provide a comprehensive understanding of the pathological processes involved.

Fibrotic skin disease represents a major global healthcare burden, characterized by fibroblast hyperproliferation and excessive accumulation of extracellular matrix. Fibroblasts are found to be heterogeneous in multiple fibrotic diseases, but fibroblast heterogeneity in fibrotic skin diseases is not well characterized. In this study, we explore fibroblast heterogeneity in keloid, a paradigm of fibrotic skin diseases, by using single-cell RNA-seq.

Keloids represent one extreme of aberrant dermal wound healing. One of the important characteristics of keloids is uncontrolled fibroblasts proliferation. However, the mechanism of excessive proliferation of fibroblasts in keloids remains elusive.

We report a transcriptome assembly and expression profiles from RNA-Seq data and identify genes responsible for culm gall formation in Zizania latifolia induced by Ustilago esculenta. The smut fungus Ustilago esculenta can induce culm gall in Zizania latifolia, which is used as a vegetable in Asian countries. However, the underlying molecular mechanism of culm gall formation is still unclear.

Introduction: Bu-Shen-Ning-Xin Decoction (BSNXD), a traditional Chinese medicinal composition, has been used as a remedy for postmenopausal osteoporosis, but its effects on bone metabolism and the uterus have not been reported.

Purpose: We aimed to determine the respective effects of BSNXD on the bones and the uterus of ovariectomized (OVX) mice to evaluate the efficacy and safety of this herbal formula.

Materials And Methods: Postmenopausal osteoporosis animal models that were generated by ovariectomy were treated with BSNXD.

Introduction: Bu-Shen-Ning-Xin decoction (BSNXD) is a traditional Chinese medicinal composition that has been used as a remedy for postmenopausal osteoporosis, but the mechanisms affecting bone metabolism are not fully understood.

Purpose: We investigated the molecular mechanism and signaling pathway underlying the effect of BSNXD on osteoclastogenesis.

Materials And Methods: A postmenopausal osteoporosis animal model generated by ovariectomy was administered BSNXD and drug-derived serum was prepared.

Mesenchymal stem cells (MSCs) are a type of stem cell that has multidirectional differentiation abilities. Under certain inducing factors, MSCs can differentiate into osteoblasts and adipocytes. Adipocytes and osteoblasts are derived from MSCs, and decreased osteoblastogenesis and increased adipocytes may be a primary cause of postmenopausal osteoporosis (PMO).

Immunosenescence is a result of progressive decline in immune system function with advancing age. Epidermal Langerhans cells (LCs), belonging to the dendritic cell (DC) family, act as sentinels to play key roles in the skin immune responses. However, it has not been fully elucidated how aging affects development and function of LCs.

MicroRNAs (miRNAs) are evolutionarily conserved small non-coding RNAs that repress target genes at post-transcriptional level. Langerhans cells (LCs) are skin-residential dendritic cells (DCs) with a life cycle distinct from other types of DCs. miRNA deficiency interrupts the homoeostasis and function of epidermal LCs, suggesting the critical roles of miRNAs in LC development and function.

Langerhans cells (LCs) are skin-residential dendritic cells that regulate skin immunity. MicroRNAs (miRNAs) are key regulators in the control of biological functions in a variety of cell types. Deletion of all miRNAs interrupts the homeostasis and function of epidermal LCs.

Article Synopsis
  • TSA, a histone deacetylase (HDAC) inhibitor, shows potential in reducing the severity of allergic contact dermatitis (ACD) induced by DNFB in mice.
  • Treatment with TSA resulted in decreased epidermal Langerhans cells (LCs) and splenic dendritic cells (DCs), indicating a regulatory effect on immune cell function during ACD.
  • The study suggests that HDACs could be targeted for therapeutic purposes in ACD and other skin diseases associated with LCs.

Objective: To investigate the induction of antitumor immune responses and therapeutic effects of 10-hydroxycamptothecinc-treated (HCPT) DC-Hepa fusion vaccines by DC fused with hepal-6 cell from hepatoma.

Methods: The fused cells were isolated by magnetic cell sorting and adherent culture. Cell apoptosis was detected by Rhodamine123/PI double-labeled assay, CTL activity by 4 h (51)Cr releasing assay.
