Objective To investigate the effects of different cytokines (IL-22,IL-17,IFN-γ) on proliferation and apoptosis of human pleural mesothelial cells (PMC) during Mycobacterium tuberculosis infection.Methods The expressions of IL-22R,IL-17R and IFN-γR1 on PMC purified from tuberculous pleural effusion (TPE) were determined by flow cytometry.The effects of one or more of IL-22,IL-17,and IFN-γ on Ki-67 expression and apoptosis of PMC were explored.Ki-67 expression of PMC under the conditions of the absence or presence of exogenous TPE and with a combination of control IgG,or anti-IL-22,-IL-17 or-IFN-γ mAbs were determined.Results (1) During Mycobacterium tuberculosis infection,IL-22R,IL-17R and IFN-γR1 were highly expressed on the surface of PMC [(86.2 ± 2.9)%,(41.5 ±4.4)% and (64.9 ±5.8)% respectively].(2) In group IL-22 + IL-17,the percentage of Ki-67+ PMC was(31.5 ±2.0)% and (26.1 ± 2.4)% respectively,which were both higher than that in the medium group [(14.6 ± 0.7) %] (q =6.8 and 4.9,respectively,both P < 0.05).In group IFN-γ,the percentage of Ki-67 + PMC was (5.2 ± 1.2) %,which was lower than that in the medium group (q =5.0,P < 0.05).In group IFN-γ + IL-22 and IFN-γ + IL-17,the percentages of Ki-67 + PMC were (23.4 ± 1.7)% and (21.8±3.8)% respectively,which were both higher than that in group IFN-γ (q =7.3 and 6.7,respectively,both P < 0.05).In group TPE and TPE + IgG,the percentages of Ki-67 + PMC were (63 ±9) % and(63 ± 11)% respectively,which were both higher than that in the medium group (q =19.6 and 19.7,respectively,both P <0.05).In group TPE + anti-IFN-γγ mAb,the percentage of Ki-67 + PMC was (82 ±4) %,which was even higher than that in group TPE + IgG (q =7.5,P < 0.05).In group TPE +anti-IL-22 mAb,the percentage of Ki-67 + PMC was (34 ± 3) %,which was lower than that in group TPE +IgG (q =11.8,P < 0.05).In group TPE + anti-IL-17 mAb,the percentage of Ki-67 + PMC was (58 ±5) %,which showed no significant difference compared to that in group TPE + IgG (q =2.1,P > 0.05).(3) The percentage of apoptotic PMC in group IFN-γ was(19.3 ± 1.1)%,which was higher than that in the medium group [(4.3 ± 0.6) %] (q =33.4,P < 0.05).The percentage of apoptotic PMC in group IL-22 + IL-17 was (3.8 ± 0.6) % and (5.7 ± 0.8) % respectively,which had no significant difference compared to that in the medium group (q =1.3 and 3.0,respectively,both P > 0.05).The percentage of apoptotic PMC in group IFN-γ + IL-22 and IFN-γ + IL-17 were (6.5 ± 0.7) % and (8.7 ± 1.7) %respectively,which were both lower than that in group IFN-γ (q =28.5 and 23.6,respectively,both P <0.05).Conclusion During Mycobacterium tuberculosis infection,IFN-γ inhibited PMC proliferation and contributed to apoptosis,while IL-22 and IL-17 promoted PMC proliferation without influencing PMC apoptosis and succeeded in reversing the effect induced by IFN-γ.
