ABSTRACT
Objective:To study the characteristics and clinical significance of mitochondrial injury of T lymphocyte subsets in patients with autoimmune hepatitis (AIH).Methods:The clinical data of 57 patients with AIH (AIH group) from June to December 2021 in Hangzhou Xixi Hospital were retrospectively analyzed, while 60 healthy physical examiners were included as healthy group. The peripheral blood T lymphocyte subsets (CD 8+ T lymphocyte count and CD 4+ T lymphocyte count) were detected by flow cytometry, and matched mitochondrial staining value according to certain algorithm was used to determine the mitochondrial damage of helper T lymphocyte (Th cell) and suppressor T lymphocyte (Ts cell). The levels of IgG, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured using a Roche E170 automatic electrochemiluminescence immunoassay. Anti-nuclear antibody (ANA) titer was measured by immunofluorescence. Multivariate Logistic regression was used to analyze the independent risk factors of mitochondrial damage of Th cell and Ts cell in patients with AIH. Results:The ALT, AST, IgG, positive rate of ANA titer, CD 4+ T lymphocyte count, CD 8+ T lymphocyte count, rate of Th cell mitochondrial injury and rate of Ts cell mitochondrial injury in AIH group were significantly higher than those in healthy group: (118.90 ± 37.61) U/L vs. (30.96 ± 14.37) U/L, (102.40 ± 36.51) U/L vs. (31.12 ± 14.06) U/L, (18.40 ± 3.71) g/L vs. (13.89 ± 1.98) g/L, 96.49% (55/57) vs. 16.67% (10/60), 438 (323, 637) × 10 6/L vs. 398 (272, 469) × 10 6/L, 296 (211, 296) × 10 6/L vs. 270 (193, 322) × 10 6/L, 61.40% (35/57) vs. 8.33% (5/60) and 82.46% (47/57) vs. 11.67% (7/60), and there were statistical differences ( P<0.01 or <0.05). Multivariate Logistic regression analysis result showed that the AST elevated and CD 8+ T lymphocyte count reduced were the independent risk factors of Ts cell mitochondrial injury in patients with AIH ( OR = 1.06 and 0.99, 95% CI 1.01 to 1.10 and 0.99 to 1.00, P<0.05); the ALT elevated and IgG elevated were the independent risk factors of Th cell mitochondrial injury in patients with AIH ( OR = 1.08 and 1.66, 95% CI 1.02 to 1.14 and 1.11 to 2.48, P<0.05). Conclusions:It is of positive clinical significance to measure the T lymphocyte subtype mitochondrial injury in patients with AIH. The probability of mitochondrial injury of T lymphocyte subtype can be predicted by biochemical indexes such as ALT, AST and IgG, so as to indirectly evaluate the liver cell necrosis.
ABSTRACT
OBJECTIVE@#To observe the clinical efficacy of bamboo-based medicinal moxibustion for chronic fatigue syndrome (CFS), and to preliminarily explore its action mechanism.@*METHODS@#Sixty-four patients with CFS were randomly divided into a moxibustion group (32 cases, 1 case dropped off, 1 case excluded) and an acupuncture group (32 cases, 2 cases dropped off). The patients in the moxibustion group were treated with bamboo-based medicinal moxibustion, while the patients in the acupuncture group were treated with routine acupuncture. Both groups were treated once a day, 6 days as a course of treatment with 1 day interval, for a total of 2 courses of treatment. Before treatment, 1 and 2 courses into treatment and in the follow-up of 14 days after treatment, the fatigue scale-14 (FS-14) and somatic and psychological health report (SPHERE) scores were observed in the two groups. Before and after treatment, the contents of CD+3, CD+4, CD+8 of peripheral blood T lymphocyte subsets were measured and CD+4/CD+8 ratio was calculated; the clinical efficacy of the two groups was compared.@*RESULTS@#Compared before treatment, the FS-14 and SPHERE scores in the two groups were decreased 1 and 2 courses into treatment and in the follow-up (P<0.01), and the FS-14 and SPHERE scores in the moxibustion group were lower than those in the acupuncture group (P<0.01, P<0.05). Compared before treatment, the contents of CD+3, CD+4 and CD+4/CD+8 ratio in the moxibustion group were increased after treatment (P<0.01). There was no significant difference of CD+3, CD+4, CD+8 and CD+4/CD+8 ratio between before and after treatment in the acupuncture group (P>0.05). After treatment, the contents of CD+3 and CD+4 in the moxibustion group were higher than those in the acupuncture group (P<0.05). The total effective rate was 93.3% (28/30) in the moxibustion group, which was higher than 73.3% (22/30) in the acupuncture group (P<0.05).@*CONCLUSION@#Bamboo-based medicinal moxibustion could improve the physical and mental fatigue symptoms and psychological status in patients with CFS. Its effect may be related to regulating the contents of CD+3, CD+4 of peripheral blood T lymphocyte subsets and CD+4/CD+8 ratio.

ObjectiveTo explore the effect of Tongxie Yaofang on the immune microenvironment of colorectal cancer in mice under chronic stress and the underlying mechanism. MethodA total of 40 male SPF BABL/C mice were randomized into normal group， stress group， Tongxie Yaofang group （13.65 g·kg-1）， and Tongxie Yaofang-stress group （13.65 g·kg-1）， with 10 in each group. Chronic restraint stress was induced in mice and administration （ig） of Tongxie Yaofang began after 7 days of stress. On the 14th day， forced swim and tail suspension tests were used to examine the behavioral changes of mice after stress and the subcutaneous colorectal tumor was implanted in each group of mice. The effect of this prescription on the body mass and tumor volume of mice was observed. After the last administration， mouse serum and tumor samples were collected. The content of T lymphocytes （CD3+， CD4+， CD8+， and CD4+/CD8+） in tumor was detected by immunohistochemistry and flow cytometry and levels of corticosterone （CORT） in peripheral blood， and interleukin （IL）-2， interferon-γ （IFN-γ）， IL-6， and IL-10 in the serum were determined by enzyme-linked immunosorbent assay （ELISA）. The protein expression of inhibitor of nuclear factor-κB（IκB） kinase α/β （IKKα/β）， nuclear factor-κB （NF-κB）α （IκBα）， NF-κB p65， and phosphorylated （p）-NF-κB p65 was measured by Western blot. ResultCompared with the normal group， the stress group had large tumor volume （P<0.05）， low content of CD3+， CD4+， and CD4+/CD8+ （P<0.05， P<0.01）， high content of CD8+， low content of T helper 1 （Th1）-secreted IFN-γ （P<0.05）， high content of T helper 2 （Th2）-secreted IL-10 （P<0.05） and CORT （P<0.05）， high protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05）， and low protein expression of IκBα （P<0.05）. Compared with the normal group， the Tongxie Yaofang group showed slow tumor growth， high content of CD3+， CD4+， and CD4+/CD8+ （P<0.01）， low content of CD8+ （P<0.05）， high content of Th1-secreted IL-2 and IFN-γ （P<0.05）， low content of Th2-secreted IL-6 and IL-10 （P<0.05）， low content of CORT， low protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05）， and high protein expression of IκBα （P<0.01）. Tongxie Yaofang-stress group demonstrated slower tumor growth， higher content of CD3+， CD4+， and CD4+/CD8+ （P<0.01）， smaller content of CD8+ （P<0.05）， higher content of IL-2 and IFN-γ （P<0.05）， lower content of IL-6， IL-10 （P<0.05）， and CORT （P<0.05）， lower protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05，P<0.01）， and higher protein expression of IκBα （P<0.01） than the stress group. ConclusionTongxie Yaofang can delay the growth of colorectal cancer under chronic stress and alleviate the deterioration of the immune microenvironment， possibly by inhibiting NF-κB signaling pathway， regulating the function of T lymphocyte subsets， and thus suppressing the secretion of pro-inflammatory factors.
ABSTRACT
Objective:To investigate the effects of nedaplatin combined with docetaxel on serum tumor markers and T lymphocyte subsets in patients with epithelial ovarian cancer.Methods:Ninety-two patients with epithelial ovarian cancer who received treatment from March 2016 to December 2017 were included in this study. They were randomly assigned to undergo nedaplatin combined with docetaxel (observation group, n = 46) or cisplatin combined with paclitaxel (control group, n = 46). Both groups received two 21-day courses of treatment. Serum tumor marker level, T lymphocyte subset level, clinical efficacy, incidence of adverse reactions, and 2-year survival rate were compared between the two groups. Results:After treatment, serum cancer antigen 125 (CA125), cancer antigen 199 (CA199), and carcinoembryonic antigen (CEA) levels were (45.84 ± 22.46) U/mL, (35.13 ± 15.03) U/mL, (16.21 ± 3.20) U/mL, respectively in the control group and they were (28.33 ± 20.11) U/mL, (14.82 ± 10.11) U/mL, (5.16 ± 1.33) U/mL, respectively in the observation group. After treatment, CA125, CA199, and CEA levels in each group were significantly decreased compared with before treatment. After treatment, CA125, CA199, and CEA levels were significantly lower in the observation group than in the control group ( t = 3.94, 7.61, 21.63, all P < 0.05). After treatment, the numbers of CD3 +, CD4 +, CD8 + cells in the control group were (16.22 ± 3.12)%, (15.20 ± 1.46)%, (29.21 ± 5.17)%, respectively, and they were (31.22 ± 4.11)%, (24.99 ± 1.71)%, (24.25 ± 4.45)% respectively in the observation group. After treatment, the numbers of CD3 + and CD4 + cells in the observation group were significantly higher than those in the control group ( t = 19.72, 29.53, both P < 0.05). After treatment, the number of CD8 + cells in the observation group was significantly lower than that in the control group ( t = 4.93, P < 0.05). Total response rate was significantly higher in the observation group than in the control group [78.26% (36/46) vs. 58.70% (27/46), χ2 = 4.08, P < 0.05]. The incidence of adverse reactions was significantly lower in the observation group than in the control group [23.91% (11/46) vs. 45.65% (21/46), χ2 = 4.79, P < 0.05]. The 2-year survival rate was significantly higher in the observation group than in the control group [43.48% (20/46) vs. 23.91% (11/46), χ2 = 3.94, P < 0.05]. Conclusion:Nedaplatin combined with docetaxel is highly effective on epithelial ovarian cancer. The combined therapy can greatly reduce serum CA125, CA199, and CEA levels but has no great effects on T lymphocyte subsets. It can increase the survival rate but has no serious adverse reactions.
ABSTRACT
Objective:To investigate the levels and correlation between myeloid-derived suppressor cell (MDSC) and T lymphocyte subsets in peripheral blood of patients with active pulmonary tuberculosis.Methods:A total of 38 patients with active pulmonary tuberculosis in Nanjing Second Hospital from February 2019 to June 2020 were selected as the tuberculosis group, and 23 healthy outpatient physical examination patients were selected as the healthy control group during the same period. The levels of MDSC, clinically related indicators, inflammatory cytokines and lymphocyte subsets were compared between each group, and the correlation between MDSC and lymphocyte subsets was analyzed. Meanwhile, the levels of MDSC and lymphocyte subsets before and after treatment were compared.Results:The MDSC and CRP in tuberculosis group were higher than those in healthy group: (16.41 ± 2.13)% vs. (1.82 ± 0.54)%, (25.42 ± 10.56) mg/L vs. (5.82 ± 1.39) mg/L ( P<0.05). Serum inflammatory cytokines tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β, IL-10 and interferon (IFN)-γ in tuberculosis group were significantly higher than those in healthy control group ( P<0.05). T lymphocyte subsets CD 3+ T cell, CD 4+ T cell, CD 8+ T cell and CD 16/56+ nature killer (NK) cell in tuberculosis group were significantly lower than those in healthy control group ( P<0.05), while the number of CD 19+ B cell was not statistically significant ( P>0.05). Correlation analysis showed that MDSC was negatively correlated with T lymphocyte subsets CD 3+ T cell ( r = -0.73, P<0.001), CD 4+ T cell ( r = -0.68, P<0.001) and CD 8+ T cell ( r = -0.53, P = 0.001), but had no significant correlation with CD 16/56+ NK cell ( r = -0.10, P = 0.561). CD 3+ T cell, CD 4+ T cell, CD 8+ T cell and CD 16/56+ NK cell were significantly different in peripheral blood MDSC before and after treatment ( P<0.05). Conclusions:MDSC, CD 3+ T cell, CD 4+ T cell, CD 8+ T cell and CD 16/56+ NK cell have a guiding role in the diagnosis and evaluation of the curative effect of active pulmonary tuberculosis, with high value in clinical application.
ABSTRACT
Objective:To investigate the relationship between substance addiction, T lymphocytes and depression in methamphetamine (MA) withdrawal patients.Methods:A total of 105 men who met the inclusion criteria were selected from compulsory isolation drug rehabilitation center of Baini lake, Hunan Province.All participants were suveyed by desires for drug questionnaire(DDQ) and self-rating depression scale (SDS), and the function of T lymphocyte subsets were detected by flow cytometry.All data were managed and analyzed using the SPSS 21.0 and AMOS 21.0 statistical software packages.Results:(1) The respondents were mainly junior high school or below (81.9%), unmarried and divorced (67.6%), unemployed (55.2%), hot suction (47.6%), and careless friends (32.4%), and 67.7% of MA abstinence had depressive symptoms. (2) SDS was positively correlated with desire and intention(DI), negative reinforcement (NR) and CD8+ %( r=0.408-0.897, all P<0.01), while negatively correlated with medication control, CD3+ %, CD4+ %, and CD4+ /CD8+ ( r=-0.792--0.263, all P<0.01). DI had significant positive correlation with CD8 + %( r=0.216, P<0.05), and negative correlation with CD4+ /CD8+ ( r=-0.217, P<0.05). NR had significant positive correlation with CD8 + %( r=0.259, P<0.05), and had significant negative correlations with CD3+ %, CD4+ %, and CD4+ /CD8+ ( r=-0.275-0.200, all P<0.05). Medication cotrol had a significant negative correlation with CD8+ %( r=-0.363, P<0.05), and significant positive correlations with CD4+ % and CD4+ /CD8+ ( r=0.288, 0.261, both P<0.05). (3)The model fitting index showed that DI, NR and medication control had significant direct effects on T lymphocyte subsets (all P<0.05). DI, medication control and T lymphocyte subsets had significant direct effects on self-evaluation of depressive symptoms (all P<0.05). NR, DI and medication control indirectly affected depressive symptoms through T lymphocyte subsets (all P<0.05). There were three path relationships: ① DI indirectly affected SDS via T lymphocyte subsets; ② Medication control indirectly affected SDS via T lymphocyte subsets; ③ NR indirectly affected SDS via T lymphocyte subsets. Conclusion:The structural equation model suggests that the degree of addiction in MA abstinence affecting depressive mood may be related to hypofunctional T lymphocyte subsets and provide methods for the prevention and treatment of drug addiction.

Objective:To discuss the changes and clinical significance of CD4 -CD8 -double negative T lymphocytes (DNT), T lymphocyte subsets, natural killer (NK) cells and CD 19+ B lymphocytes in peripheral blood of children with confirmed Mycoplasma pneumoniae pneumonia(MPP). Methods:A retrospective analysis was conducted on children with pneumonia admitted to the Children′s Hospital of Shanghai Jiaotong University from January 2019 to February 2020.The patients were stratified into 3 age groups: 0-3 years old, 4-7 years old and ≥8 years old, and they received detection of peripheral blood T lymphocyte subsets in acute stage.As observation group, 185 MPP children were further divided into MPP common group (117 cases) and MPP severe group (68 cases) based on their state of pneumonia.In addition, 69 cases with non-MPP were selected as control group.The absolute counts of DNT, T lymphocyte subsets, NK cells and CD 19+ B lymphocytes in peripheral blood were tested by flow cytometry.DNT levels in diffe-rent age groups were analyzed. Results:(1) The number of CD3 + [1.527(1.059, 2.348)×10 9/L], CD4 + [0.771(0.559, 1.206)×10 9/L], CD8 + [0.528(0.343, 0.773)×10 9/L], CD4 + /CD8 + [1.570(1.130, 1.945)], CD 19+ [0.455(0.285, 0.771)×10 9/L] and DNT[0.168(0.095, 0.294)×10 9/L] lymphocytes in peripheral blood in the observation group were lower than those in the control group[2.116(1.506, 3.728)×10 9/L, 1.170(0.685, 2.114)×10 9/L, 0.696(0.414, 1.226)×10 9/L, 1.780(1.230, 2.210), 0.694(0.483, 1.343)×10 9/L, 0.235(0.134, 0.391)×10 9/L], and the differences were statistically significant (all P<0.05). (2) In addition, the number of CD3 + [1.704(1.215, 2.566)×10 9/L], CD4 + [0.855(0.628, 1.267)×10 9/L], CD8 + [0.582(0.378, 0.843)×10 9/L], NK[0.269(0.176, 0.417)×10 9/L], CD 19+ [0.461(0.317, 0.808)×10 9/L] and DNT[0.180(0.117, 0.306)×10 9/L]lymphocytes in peripheral blood in MPP common group were significantly higher than those in MPP severe group [1.369(0.831, 1.760)×10 9/L, 0.676(0.433, 0.924)×10 9/L, 0.495(0.292, 0.699)×10 9/L, 0.196(0.112, 0.380)×10 9/L, 0.391(0.181, 0.730)×10 9/L, 0.143(0.071, 0.265)×10 9/L], and the differences were statistically significant (all P<0.05). (3) Moreover, in acute phase, the number of DNT in observation group had no significant differences with that in control group of the same age ( P>0.05). In the observation group, the number of DNT[0.230(0.125, 0.364)×10 9/L] in 0-3 years old group was higher than that in 4-7 years old group[0.143(0.085, 0.233)×10 9/L] and ≥ 8 years old group[0.144(0.078, 0.271)×10 9/L]. In 0-3 years old group, the more serious the disease, the lower the indicators, and the differences were statistically significant (all P<0.05). Conclusions:In acute phase, the changes of lymphocyte subsets in peripheral blood of MPP children are remarkable, and the absolute count of DNT lymphocytes in peripheral blood decreased.The decreasing level of DNT has negative association with the severity of pneumonia.The absolute count of DNT was higher in young children.So monitoring peripheral blood DNT may be of some value to the assessment of immune function or pneumonia state in children with MPP.
ABSTRACT
Objective:To analyze the correlation between 1H-MRS in hippocampus and peripheral blood cytokines and T lymphocyte subsets in patients with temporal lobe epilepsy, and to explore the relationship between immune dysfunction and the degree of neuronal injury. Methods:Fifty patients with temporal lobe epilepsy were selected from Affiliated Hospital of Xuzhou Medical University from October 2020 to July 2021.Clinical data of all patients were collected and they were divided into two groups according to MRI results of epileptic sequence: abnormal hippocampal MRI group ( n=20) and normal hippocampal MRI group ( n=30). Bilateral 1H-MRS scanning of hippocampal and detection of T lymphocyte subsets and cytokines in peripheral blood during interictal period were performed in both groups. The levels of hippocampal metabolites NAA, NAA/(Cr+ Cho), T lymphocyte subsets and cytokines in peripheral blood of the two groups were compared.At the same time, the levels of NAA and NAA/ (Cr+ Cho) in the hippocampus on the abnormal side and the normal side in the abnormal hippocampal MRI group were compared within the group. Finally, the correlation between the levels of metabolites NAA, NAA/ (Cr+ Cho) in the hippocampus on the abnormal side obtained by 1H-MRS scanning and T lymphocyte subsets and cytokines in the abnormal group of MRI was analyzed. The data were statistically analyzed by SPSS 26.0 software. Independent sample t-test or Mann-Whitney U test was used for comparison between the two groups. Paired sample t-test was used for intra group comparison of different sides. Spearman correlation analysis was used to analyze the correlation between each index. Results:The NAA and NAA/(Cr+ Cho) values of the abnormal MRI group(normal side NAA: (1.22±0.37), NAA/(Cr+ Cho): (0.56±0.15). abnormal side NAA: (1.02±0.34), NAA/(Cr+ Cho): (0.48±0.13)) were significantly lower than those of the normal MRI group (NAA: (1.51±0.36), NAA/(Cr+ Cho): (0.73±0.19))(NAA: t=2.705, 4.800, both P<0 05; NAA/(Cr+ Cho): t=3.394, 4.914, both P<0 05). The values of NAA and NAA/(Cr+ Cho) in the abnormal side in the MRI abnormal group were significantly lower than those in the normal side( t=6.467, P<0 05). The levels of IL-1β(11.19(3.56, 20.98)pg/ml), IL-5 (3.12(1.86, 6.41)pg/ml), TNF-α(2.55(1.19, 8.28)pg/ml), CD4+ T lymphocytes((43.13±6.82)%) and Th/Ts((1.96±0.66)) in the hippocampal MRI abnormal group were significantly higher than those in normal MRI group (IL-1β: 3.27(1.63, 6.17)pg/ml, IL-5: 1.15(0.96, 2.96)pg/ml, TNF-α: 1.34(1.02, 2.36)pg/ml, CD4+ T: (38.01±7.21)%, Th/Ts: (1.48±0.53))( Z=-3.041, -2.516, -2.496, all P<0.05; t=2.511, 2.810, both P<0 05). The level of CD8+ T ((23.48±5.33)%) in peripheral blood of abnormal MRI group was significantly lower than that of normal group CD8+ T((27.18±6.08)%)( t=2.210, P<0.05). In the abnormal MRI group, the levels of NAA and NAA/ (Cr+ Cho) in the abnormal hippocampus were negatively correlated with the levels of IL-1β, IL-5 and TNF- α ( r=-0.612--0.463, all P<0.05), and positively correlated with CD8+ T lymphocytes ( r=0.537, 0.478, P<0.05). Conclusion:There is neuronal damage and dysfunction in the abnormal hippocampal region of patients with temporal lobe epilepsy with abnormal hippocampal formation, and the degree of neuronal damage is highly correlated with CD8+ T lymphocytes, IL-5, IL-1β and TNF-α in peripheral blood. The imbalance of interictal lymphocyte subsets and chronic inflammatory response may play an important role in the pathogenesis of epilepsy and neuronal injury .
ABSTRACT
The γδ T cells are unconventional lymphocytes that function in both innate and adaptive immune responses against various intracellular and infectious stresses. The γδ T cells can be exploited as cancer-killing effector cells since γδ TCRs recognize MHC-like molecules and growth factor receptors that are upregulated in cancer cells, and γδ T cells can differentiate into cytotoxic effector cells. However, γδ T cells may also promote tumor progression by secreting IL-17 or other cytokines. Therefore, it is essential to understand how the differentiation and homeostasis of γδ T cells are regulated and whether distinct γδ T cell subsets have different functions. Human γδ T cells are classified into Vδ2 and non-Vδ2 γδ T cells. The majority of Vδ2 γδ T cells are Vγ9δ2 T cells that recognize pyrophosphorylated isoprenoids generated by the dysregulated mevalonate pathway. In contrast, Vδ1 T cells expand from initially diverse TCR repertoire in patients with infectious diseases and cancers. The ligands of Vδ1 T cells are diverse and include the growth factor receptors such as endothelial protein C receptor. Both Vδ1 and Vδ2 γδ T cells are implicated to have immunotherapeutic potentials for cancers, but the detailed elucidation of the distinct characteristics of 2 populations will be required to enhance the immunotherapeutic potential of γδ T cells. Here, we summarize recent progress regarding cancer immunology of human γδ T cells, including their development, heterogeneity, and plasticity, the putative mechanisms underlying ligand recognition and activation, and their dual effects on tumor progression in the tumor microenvironment.
