CD8 + T and NK cells characterized by upregulation of NPEPPS and ABHD17A are associated with the co-occurrence of type 2 diabetes and coronary artery disease. Front Immunol 2024; 15:1267963. [PMID: 38464509 PMCID: PMC10921359 DOI: 10.3389/fimmu.2024.1267963] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 01/22/2024] [Indexed: 03/12/2024] Open
Abstract
Background Coronary artery disease (CAD) and type 2 diabetes mellitus (T2DM) are closely related. The function of immunocytes in the pathogenesis of CAD and T2DM has not been extensively studied. The quantitative bioinformatics analysis of the public RNA sequencing database was applied to study the key genes that mediate both CAD and T2DM. The biological characteristics of associated key genes and mechanism of CD8+ T and NK cells in CAD and T2DM are our research focus. Methods With expression profiles of GSE66360 and GSE78721 from the Gene Expression Omnibus (GEO) database, we identified core modules associated with gene co-expression relationships and up-regulated genes in CAD and T2DM using Weighted Gene Co-expression Network Analysis (WGCNA) and the 'limma' software package. The enriched pathways of the candidate hub genes were then explored using GO, KEGG and GSEA in conjunction with the immune gene set (from the MSigDB database). A diagnostic model was constructed using logistic regression analysis composed of candidate hub genes in CAD and T2DM. Univariate Cox regression analysis revealed hazard ratios (HRs), 95% confidence intervals (CIs), and p-values for candidate hub genes in diagnostic model, while CIBERSORT and immune infiltration were used to assess the immune microenvironment. Finally, monocytes from peripheral blood samples and their immune cell ratios were analyzed by flow cytometry to validate our findings. Results Sixteen candidate hub genes were identified as being correlated with immune infiltration. Univariate Cox regression analysis revealed that NPEPPS and ABHD17A were highly correlated with the diagnosis of CAD and T2DM. The results indicate that CD8+ T cells (p = 0.04) and NKbright cells (p = 3.7e-3) are significantly higher in healthy controls than in individuals with CAD or CAD combined with T2DM. The bioinformatics results on immune infiltration were well validated by flow cytometry. Conclusions A series of bioinformatics studies have shown ABHD17A and NPEPPS as key genes for the co-occurrence of CAD and T2DM. Our study highlights the important effect of CD8+ T and NK cells in the pathogenesis of both diseases, indicating that they may serve as viable targets for diagnosis and therapeutic intervention.

Abstract
Objective To reveal the value of single lymphocyte subpopulation and their ratios in
the progression of sepsis. Methods From January 2019 to March 2021, 39 sepsis patients, 16 septic shock
patients, and 50 healthy volunteers were recruited in the Second Xiangya
Hospital for this cross-sectional study. The absolute quantitation of CD4+T,
CD8+T, B lymphocytes, and NK cells in peripheral blood were determined by
flow cytometry. SPSS Software was used to analyze the results. Results On the whole, the numbers of lymphocytes in the sepsis group and in the
septic shock group were lower than that in the healthy control group.
Surprisingly, the percentage of CD8+T lymphocytes in the septic shock group
was slightly higher than that in the sepsis group. The percentage of B
lymphocytes in the sepsis group was higher than that in the healthy control
group. The AUC of CD8+T/B was 0.724, with the sensitivity and specificity
being 75.00% and 71.79%, respectively. Conclusion The immune expression pattern of patients with sepsis was not a simple
decrease in the number of lymphocytes. The change in the ratios of
lymphocyte subpopulation might be more meaningful along the development and
progression of sepsis. The ratio of CD8+T/B could be used to diagnose the
progression of sepsis and reduce the misdiagnosis rate to a certain
extent.

Mycobacterium bovis Bacille-Calmette-Guérin Infection Aggravates Atherosclerosis. Front Immunol 2020; 11:607957.

Abstract
Tuberculosis has been associated with increased risk of atherosclerotic cardiovascular disease. To examine whether mycobacterial infection exacerbates atherosclerosis development in experimental conditions, we infected low-density lipoprotein receptor knockout (Ldlr-/-) mice with Mycobacterium bovis Bacille-Calmette-Guérin (BCG), an attenuated strain of the Mycobacterium tuberculosis complex. Twelve-week old male Ldlr-/- mice were infected with BCG (0.3–3.0x106 colony-forming units) via the intranasal route. Mice were subsequently fed a western-type diet containing 21% fat and 0.2% cholesterol for up to 16 weeks. Age-matched uninfected Ldlr-/- mice fed with an identical diet served as controls. Atherosclerotic lesions in aorta were examined using Oil Red O staining. Changes induced by BCG infection on the immunophenotyping profile of circulating T lymphocytes and monocytes were assessed using flow cytometry. BCG infection increased atherosclerotic lesions in en face aorta after 8 weeks (plaque ratio; 0.021±0.01 vs. 0.013±0.01; p = 0.011) and 16 weeks (plaque ratio, 0.15±0.13 vs. 0.06±0.02; p = 0.003). No significant differences in plasma cholesterol or triglyceride levels were observed between infected and uninfected mice. Compared to uninfected mice, BCG infection increased systemic CD4/CD8 T cell ratio and the proportion of Ly6Clow non-classical monocytes at weeks 8 and 16. Aortic plaque ratios correlated with CD4/CD8 T cell ratios (Spearman’s rho = 0.498; p = 0.001) and the proportion of Ly6Clow non-classical monocytes (Spearman’s rho = 0.629; p < 0.001) at week 16. In conclusion, BCG infection expanded the proportion of CD4+ T cell and Ly6Clow monocytes, and aggravated atherosclerosis formation in the aortas of hyperlipidemic Ldlr-/- mice. Our results indicate that mycobacterial infection is capable of enhancing atherosclerosis development.

Chai D, Kong X, Lu S, Zhang J. CD4+/CD8+ ratio positively correlates with coronary plaque instability in unstable angina pectoris patients but fails to predict major adverse cardiovascular events. Ther Adv Chronic Dis 2020; 11:2040622320922020. [PMID: 32489573 PMCID: PMC7238310 DOI: 10.1177/2040622320922020] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2019] [Accepted: 03/30/2020] [Indexed: 01/28/2023] Open
Abstract
Background: The association between CD4+/CD8+ ratio and coronary plaque instability in
patients with unstable angina pectoris (UAP) has not been investigated. We
sought to elucidate the correlation between CD4+/CD8+ ratio and plaque
instability in this patient population. Methods: We enrolled 266 UAP patients who underwent pre-intervention optical coherence
tomography (OCT) examination and percutaneous coronary intervention in our
center from January 2016 to January 2018. Features of coronary plaques in
the culprit arteries were classified as unstable plaque and stable plaque.
Primary endpoint was occurrence of a major adverse cardiovascular event
(MACE). Receiver operating characteristic (ROC) analyses were used to
determine the predictive efficacy of the CD4+/CD8+ ratio for a group of
unstable plaque patients, and binary logistic regression analysis was
performed to evaluate potential independent predictors of plaque
instability. All-cause mortality and MACE between the two groups were
analyzed. Results: UAP patients with unstable plaque had a higher CD4/CD8 ratio compared with
stable plaque patients (p < 0.05). Results of binary
logistic regression analyses showed that CD4+/CD8+ ratio ⩾1.725 and prior
stroke were predictors and risk factors of plaque instability
(p < 0.05). ROC analyses showed that CD4+/CD8+ ratio
⩾1.725 was predictive of plaque instability in UAP patients. However, the
Kaplan–Meier estimate for MACE and all-cause mortality showed no statistical
significance. Conclusions: Higher CD4+/CD8+ ratio is associated with higher risk of plaque instability
in our cohort of UAP patients. However, CD4+/CD8+ ratio was not an
independent predictor of 1-year MACE or all-cause mortality.

Abstract
Atherosclerotic cardiovascular disease (ACVD) is an inflammatory phenomenon that leads to structural abnormality in the vascular lumen due to the formation of atheroma by the deposition of lipid particles and inflammatory cytokines. There is a close interaction between innate immune cells (neutrophils, monocyte, macrophages, dendritic cells) and adaptive immune cells (T and B lymphocytes) in the initiation and progression of atherosclerosis. According to novel insights into the role of adaptive immunity in atherosclerosis, the activation of CD4+T cells in response to oxidized low-density lipoprotein-antigen initiates the formation and facilitates the propagation of atheroma, whereas CD8+T cells cause the rupture of a developed atheroma by their cytotoxic nature. Peripheral CD4+and CD8+T-cell counts were altered in patients with other cardiovascular risk factors. Furthermore, on evaluation of the feasibility of immune cells as a diagnostic tool, the blood CD4+(helper), CD8+(cytotoxic), and CD4+CD25+Foxp3+(regulatory) T cells and the ratio of CD4 to CD8 cells hold promise as biomarkers of coronary artery disease and their subtypes. T cells also could be a therapeutic target for cardiovascular diseases. The goal of this review was therefore to summarize the available information regarding immune disorders in ACVD with a special focus on the clinical implications of circulating T-cell subsets as biomarkers.

Abstract
T-cell function in female animal models of hypertension is poorly understood since most research is conducted in males. Our findings in Dahl-salt-sensitive and Dahl salt-resistant rats support prior research showing sex-specific T-cell effects in the pathophysiology of hypertension. Further studies are needed to inform clinical studies in both sexes and to provide clues into immune mechanisms underlying susceptibility and resilience to developing hypertension and associated disease.
