Abstract
Metabolic syndrome (MetS) represents a significant public health concern due to its association with an increased risk of cardiovascular disease, type 2 diabetes, and other serious health conditions. Despite extensive research, the underlying molecular mechanisms contributing to MetS pathogenesis remain elusive. This review aims to provide a comprehensive overview of the molecular mechanisms linking MetS and cluster of differentiation (CD) markers, which play critical roles in immune regulation and cellular signaling. Through an extensive literature review with a systematic approach, we examine the involvement of various CD markers in MetS development and progression, including their roles in adipose tissue inflammation, insulin resistance, dyslipidemia, and hypertension. Additionally, we discuss potential therapeutic strategies targeting CD markers for the management of MetS. By synthesizing current evidence, this review contributes to a deeper understanding of the complex interplay between immune dysregulation and metabolic dysfunction in MetS, paving the way for the development of novel therapeutic interventions.

Abstract
Diabetic kidney disease (DKD), is a common microvascular complication and a major cause of death in patients with diabetes. Disorders of immune cells and immune cytokines can accelerate DKD development of in a number of ways. As the kidney is composed of complex and highly differentiated cells, the interactions among different cell types and immune cells play important regulatory roles in disease development. Here, we summarize the latest research into the molecular mechanisms underlying the interactions among various immune and renal cells in DKD. In addition, we discuss the most recent studies related to single cell technology and bioinformatics analysis in the field of DKD. The aims of our review were to explore immune cells as potential therapeutic targets in DKD and provide some guidance for future clinical treatments.

[PMID: 37583087 DOI: 10.1111/obr.13621] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 03/18/2023] [Accepted: 07/19/2023] [Indexed: 08/17/2023]
Abstract
Obesity is characterized by chronic low-grade inflammatory responses in the adipose tissue, accompanied by pronounced insulin resistance and metabolic anomalies. It affects almost all body organs and eventually leads to diseases such as fatty liver disease, type 2 diabetes mellitus, and atherosclerosis. Recently, T cells have emerged as interesting therapeutic targets because the dysfunction of T cells and their cytokines in the adipose tissue is implicated in obesity-induced inflammation and their complicated onset. Although several recent narrative reviews have provided a brief overview of related evidence in this area, they have mainly focused on either obesity-associated T cell metabolism or modulation of T cell activation in obesity. Moreover, at present, no published review has reported on the multifaceted roles of T cells in obesity and obesity-related complications, even though there has been a significant increase in studies on this topic since 2019. Therefore, this narrative review aims to comprehensively summarize current advances in the mechanistic roles of T cells in the development of obesity and its related complications. Further, we aim to discuss relevant drugs for weight loss as well as the contradictory role of T cells in the same disease so as to highlight key findings regarding this topic and provide a valid basis for future treatment strategies.

NAN FANG YI KE DA XUE XUE BAO = JOURNAL OF SOUTHERN MEDICAL UNIVERSITY 2019; 39:554-560. [PMID: 31140419 DOI: 10.12122/j.issn.1673-4254.2019.05.09] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To investigate the effect of sputum ubiquitin ligase (Cbl-b) gene known-down on the cytotoxicity of H9 T lymphocytes against human laryngeal squamous cancer Hep-2 cells and explore the underlying mechanism. METHODS CD4+ T lymphocytes isolated from 12 patients with laryngeal squamous carcinoma and 12 healthy individuals were examined for Cbl-b mRNA expressions using RT-PCR. H9 T lymphocytes cultured in 96-well plates were transfected with Cbl-b siRNA via liposomes followed by treatment with an anti-IL-2 monoclonal antibody, with H9 T lymphocytes transfected with a scrambled sequence as the negative control. The expressions of Cbl-b mRNA and protein in the cells were detected using real-time fluorescent quantitative PCR and Western blotting, respectively. The killing effect of the treated T lymphocytes against Hep-2 cells was assessed using the cell counting kit (CCK-8). The positive expression rates of CD69 and CD25 on the surface of H9 T lymphocytes were determined using flow cytometry, and the levels of interleukin-2 (IL-2) and interferon-gamma (INF-γ) in the culture supernatants of H9 T lymphocytes were detected with ELISA. RESULTS The CD4+ T lymphocytes from patients with laryngeal squamous carcinoma showed significantly increased Cbl-b mRNA level compared with those from healthy individuals (P < 0.05). Transfection of H9 T lymphocytes with Cbl-b siRNA significantly reduced the expression levels of Cbl-b mRNA and protein (P < 0.05), which were not significantly affected by subsequent treatment of the cells with the anti-IL-2 antibody (P>0.05). At different target-effector ratios, the Cbl-b siRNA-transfected cells showed significantly higher Hep-2 cell killing rates and higher positivity rates of CD69 and CD25 expressions than the blank and negative control cells and the cells with both Cbl-b siRNA transfection and anti-IL-2 treatment (P < 0.05). Cbl-b silencing in H9 T lymphocytes resulted in significantly increased levels of IL-2 and INF-γ in the supernatant as compared with those in the blank and negative control groups (P < 0.05). CONCLUSIONS Cbl-b gene silencing effectively enhances the killing effect of H9 T lymphocytes against Hep-2 cells in vitro probably as the result of enhanced IL-2 secretion and T lymphocyte activation.

Peng J, Xiang Y. Value analysis of CD69 combined with EGR1 in the diagnosis of coronary heart disease. Exp Ther Med 2019; 17:2047-2052. [PMID: 30783476 PMCID: PMC6364247 DOI: 10.3892/etm.2019.7175] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2018] [Accepted: 11/21/2018] [Indexed: 12/23/2022] Open
Abstract
Expression and clinical significance of CD69 and early growth response (EGR1) in plasma of patients with coronary heart disease (CHD) were investigated. A total of 194 patients with CHD and 130 healthy subjects, respectively, were selected as CHD and control group, clinical data were collected and coronary angiography was performed. RT-qPCR was used to detect the expression of EGR1. Flow cytometry was used to detect the expression level of CD69 and the receiver operating characteristic curve was used to analyze the values of relative expression of CD69 and EGR1. The relative expression of CD69 in plasma of patients with CHD was higher than that in control group, while the relative expression of EGR1 was lower than that in control group. The relative expression of EGR1 in plasma of patients with CHD was negatively correlated with lipoprotein a [Lp(a)] and high sensitive C-reactive protein (hs-CRP) (r=-0.394 and -0.524, P<0.05), and the relative expression of CD69 in peripheral blood was positively correlated with [Lp(a)] and hs-CRP (r=0.352 and 0.402, P<0.05). The area under curve (AUC) of the relative expression of CD69 in peripheral blood of patients with CHD in evaluating the course of the disease of patients was 0.889 (95% CI: 0.822-0.958). The AUC of the relative expression of EGR1 in plasma in evaluating the course of the disease of patients was 0.933 (95% CI: 0.867-0.978). By the combined detection of CD69 and EGR1, it was found that the AUC was 0.954 (95% CI: 0.887-0.982). The expression level of EGR1 in plasma of patients with CHD decreased, while the expression level of CD69 increased, and both of them were related to the severity of the disease of patients, which could be used as an indicator to evaluate the progression of the patients' conditions.
