Disrupted balance of CD4 + T-cell subsets in bone marrow of patients with primary immune thrombocytopenia. Int J Biol Sci 2019; 15:2798-2814. [PMID: 31853219 PMCID: PMC6909963 DOI: 10.7150/ijbs.33779] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2019] [Accepted: 10/05/2019] [Indexed: 12/18/2022] Open
Abstract
Disequilibrium of CD4+ T-cell subpopulations in peripheral blood (PB) of patients with primary immune thrombocytopenia (ITP) has been well established, whereas the profile of CD4+ T-cell subpopulations in bone marrow (BM) remains elusive. In the present study, the frequencies of T helper 22 (Th22), Th17, Th1, Th2, follicular T helper (Tfh) cells and regulatory T cells (Tregs) as well as their effector cytokines in BM and PB from active ITP patients and healthy controls (HCs) were determined. Results showed that the frequencies of Th22, Th17, Th1, and Tfh cells were significantly higher, but Treg number was remarkably lower in BM from ITP patients than from HCs. In the ITP group, it was notable that the numbers of BM Th22, Th17, Th1, Th2, and Tfh cells were significantly elevated compared with the matched PB counterparts, while Treg number in BM was considerably reduced compared with that in PB. In consistence with the BM Th subset pattern, plasma levels of interleukin (IL)-22, IL-17A, and interferon (INF)-γ in BM from ITP patients were significantly increased compared with that from HCs. Therefore, the balance of CD4+ T-cell subsets was disrupted in both BM and PB of ITP patients, suggesting that this might play important roles in the pathophysiological process of ITP.

Tamasauskiene L, Sitkauskiene B. Role of Th22 and IL-22 in pathogenesis of allergic airway diseases: Pro-inflammatory or anti-inflammatory effect? Pediatr Neonatol 2018; 59:339-344. [PMID: 29292068 DOI: 10.1016/j.pedneo.2017.11.020] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2016] [Revised: 06/07/2017] [Accepted: 11/30/2017] [Indexed: 12/26/2022] Open
Abstract
A new population of T cells known as Th22 was described for the first time in 2009. These cells are usually identified by the production of IL-22. However, this cytokine is also secreted by other cells such as Th1, Th2, Th17, natural killers, and innate lymphoid cells. Th22 is known as a pro-inflammatory agent in allergic skin diseases. Recently, more evidence has emerged showing associations between these cells and other diseases. The role of Th22 in asthma and allergic rhinitis is controversial: some authors suggest that Th22 has a pro-inflammatory effect, while others state that Th22 has anti-inflammatory properties. The aim of this article was to review the role of Th22 and IL-22 in allergic airway diseases based on the most recent literature. This review suggests that Th22 plays a significant role in the pathogenesis of allergic airway diseases and has predominantly anti-inflammatory properties. More studies are needed to clarify the role of Th22 in more detail.

[PMID: 23463138 DOI: 10.1007/s00436-013-3350-2] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2013] [Accepted: 02/08/2013] [Indexed: 01/01/2023]
Abstract
Schistosome infection could cause significant liver damage in animal; Th2 cells play an important role in the progress of this disease. In our study, C57BL/6 mice were infected by Schistosoma japonicum and lymphocytes were isolated from the liver to detect some characteristics of interleukin-5 (IL-5)-producing T cells by different methods. The results revealed that S. japonicum infection could induce a large amount of IL-5 in mouse liver T cells by the means of fluorescent bead immunoassay and RT-PCR. Although, mouse liver contained many T cell subsets, such as Th cells, Tc cells, NKT cells, and γδ T cells. Fluorescence activated cell sorting results indicated that Th cells were the main source of IL-5 in the T cell population after phorbol 12-myristate 13-acetate and ionomycin stimulation. Moreover, the percentage of IL-5-producing Th cells continued to increase from 4 to 8 weeks after S. japonicum infection, which differed from the changes of IFN-γ(+) Th1 cells, IL-4(+) Th2 cells, and IL-17A(+) Th17 cells during S. japonicum infection. Additionally, cytokines co-expression results demonstrated that 36.2 % of IL-5(+) Th cells could express IL-4, and 10 % of it could produce IFN-γ or IL-17A. Collectively, these findings implied that IL-5-producing Th cells posses some properties which differ from other cytokines secreting Th cells.
