[Abstract]:BACKGROUND: The role of gamma delta T cells in host immunity against Mycobacterium tuberculosis (Mtb) infection has attracted more and more attention. Recent studies have reported that IL-17 secreting cells in mice infected with Mtb and BCG are mainly derived from gamma delta T cells. Recent studies in this laboratory have also found that the cells secreting IL-17 mainly come from gamma delta T cells outside the patients with active pulmonary tuberculosis (TB). The percentage of interleukin-17 (IL-17) producing gamma delta T cells (Tgamma delta 17 cells) in peripheral blood was significantly higher than that in normal controls. However, what subsets of T-gamma delta 17 cells belong to, and how the subtypes of T-gamma delta 17 cells in patients with pulmonary TB differ from those in healthy controls have not been reported. And transcription factors have been identified, but few studies have been done on the factors influencing the differentiation of T gamma delta 17 cells, such as cytokines, transcription factors and antigen regulation.
Objective: To investigate the subtypes of T gamma delta 17 cells (Vdel 1, Vdel 2 and Vdel 3-8) in peripheral blood of TB patients and healthy persons (HD) and to explore the differences between Tgamma delta 17 cells in TB patients and healthy persons, and the effects of thermostable antigen (M tb-HAg) of Mycobacterium tuberculosis (M.tb) and phosphorylated antigen (HDMAPP) on Tgamma delta 17 cells induced by cytokines. To explore the role of different lymphocyte subsets in the immune response to M.tb infection and the pathogenesis of TB.
Methods: 1. The peripheral blood samples of 70 active pulmonary tuberculosis patients, 100 HD patients and 33 silicosis patients were stained with fluorescent labeled monoclonal antibodies. The ratio of gamma delta T lymphocyte subsets (Vdel 1, Vdel 2 and Vdel 3-8) was detected by flow cytometry. 2. 24 active pulmonary tuberculosis patients and 17 HD patients were collected and the peripheral blood samples were added with phorbol alcohol ester (PMA) and phorbol alcohol ester (Vdel 3-8). Calcium ionomycin (Ionomycin) stimulated culture for 2 hours, then added monensin to culture for 4 hours. Cells were collected and labeled with fluorescent monoclonal antibodies for surface molecular and intracellular staining. Flow cytometry was used to detect the proportion of T gamma delta 17 cell subsets (Vdelta 1, Vdelta 2 and Vdelta 3-8) and. 3. Peripheral blood was isolated by density gradient centrifugation. Mononuclear cells (PBMC) were cultured with Mtb-Hag, HDMAPP and cytokines (IL-1 beta, IL-23 and TGF-beta) for 3 days, then stimulated with rIL-2 for 9 days. The collected cells were cultured with PMA/Ionomycin and Monosin for 6 hours. The ratio of T-gamma delta 17 subsets was detected by flow cytometry.
Result:
1. The percentage of gamma delta T cells in T cells in the 60-year-old newly treated group (n=16) was lower than that in the 60-year-old normal group (6.3%). The absolute value of gamma delta T cells (74.52%) in the 60-year-old retreated group (n=16) was lower than that in the 60-year-old newly treated group (n=34) of TB patients (144.69) (the absolute value unit was 101/ml).
2. The proportion of Vdelta 2+ subsets in total gamma delta T cells (60.06% and 48.82%) in the retreated group (n=16) of TB patients aged 60 years old was significantly lower than that in the normal group (73.68%) (p 0.01). The proportion of Vdelta 1+ subsets in total gamma delta T cells (25.01% and 22.61%) in the retreated group of TB patients aged 60 years old (n=32) was significantly higher than that in the normal group (n=11). The proportion of Vdelta 3-8 + subsets in total gamma delta T cells (33.17%) of TB patients aged 60 years after retreatment (n = 14) was significantly higher than that of normal people aged 60 years (n = 21) (14.49%) (p0.05). The absolute value of Vdelta 1 + subsets in total gamma delta T cells (3.71) of TB patients aged 60 years after retreatment was significantly lower than that of TB patients aged 60 years after retreatment (n = 14). The absolute value (11.71) of the treatment group (n = 10). The absolute value (3.03) of the Vdelta 3-8 + subsets in the total gamma delta T cells in the newly treated group (n = 14) of TB patients aged 60 was significantly lower than that in the newly treated group (n = 32) (14.89) (p 0.05.
3. The Vdelta 3-8 subset was the most common in Tgamma delta 17 cells of tuberculosis group, followed by Vdelta 2 subset and Vdelta 1 subset at least. The Vdelta 3-8 subset was the most common in Tgamma delta 17 cells of normal group, followed by Vdelta 1 subset and Vdelta 2 subset at least. The percentages of gamma delta T cell subsets in tuberculosis group were 5.03%, 10.52% and 75.03%, respectively.
4. Comparing the absolute values of the subtypes of T_ Delta T cells, the absolute values of V_ delta 1 and V_ delta 3-8 in the subtypes of T_ delta 17 cells in the normal group were the same, while the absolute values of V_ delta 3-8 in the subtypes of T_ delta 17 cells in the tuberculosis group increased sharply. The absolute values of the subgroup (n = 14) were 2.46, 0.19 and 2.78 respectively, while those of the gamma delta T cell subgroup (n = 23), V delta 2 (n = 24) and V delta 3-8 (n = 23) in the tuberculosis group were 0.64, 0.46 and 3.7, respectively.
5. The ratio of T gamma delta 17 in Mtb-Ag+CK group was significantly higher than that in HDMAPP+CK group. The ratio of V delta 2 in Mtb-Ag+CK group was significantly lower than that in HDMAPP+CK group.
Conclusion:
1. In normal subjects, Vdelta 2+ subsets were predominant in gamma delta T cells, while Vdelta 2+ subsets were decreased in patients with newly treated tuberculosis, retreated tuberculosis and silicosis, and Vdelta 1+ subsets were increased or Vdelta 3-8+ subsets were increased.
2. The proportion of Vdelta 2 + subsets in total gamma delta T cells in the retreated group of TB patients aged 60 was significantly lower than that in the normal group aged 60. The proportion of Vdelta 1 + subsets in total gamma delta T cells in the retreated group aged 60 was significantly higher than that in the normal group aged 60. The proportion of people aged 60 years old.
3. In normal and TB patients, the Vdelta 3-8 subset was the most common (more than 60%) in Tgam delta 17 cells, the Vdelta 2 subset was the least in normal Tgam delta 17 cells (not detected in half of the population), and the Vdelta 2 subset in Tgam delta 17 cells was significantly higher in TB patients than in normal subjects.
4. Normal PBMC, activated by Mtb-HAg and phosphoric acid antigen (HDMAPP) and cultured with inducible cytokines (IL-1 beta, IL-23 and TGF-beta) for 12 days, could induce the differentiation and proliferation of T gamma delta 17 cells. The number of T gamma delta 17 cells induced by the former was significantly higher than that by the latter. The amount of T gamma delta 17. is significantly lower than that of the latter.
