Serum Cytokines Usefulness for Understanding the Pathology in Allergic Bronchopulmonary Aspergillosis and Chronic Pulmonary Aspergillosis. J Fungi (Basel) 2022; 8:jof8050436. [PMID: 35628692 PMCID: PMC9147526 DOI: 10.3390/jof8050436] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 04/09/2022] [Accepted: 04/21/2022] [Indexed: 12/04/2022] Open
Abstract
Allergic bronchopulmonary aspergillosis (ABPA) and chronic pulmonary aspergillosis (CPA) are important fungal infections caused by Aspergillus species. An overlap of ABPA and CPA has been reported; therefore, it is critical to determine whether the main pathology is ABPA or CPA and whether antifungals are required. In this study, we investigated whether the serum cytokine profile is useful for understanding the pathology and for differentiating between these diseases. We compared the various serum cytokine levels among healthy subjects and patients diagnosed with asthma, ABPA, or CPA at Nagasaki University Hospital between January 2003 and December 2018. In total, 14 healthy subjects, 19 patients with asthma, 11 with ABPA, and 10 with CPA were enrolled. Interleukin (IL) -5 levels were significantly higher in patients with ABPA than in those with CPA, and IL-33 and tumor necrosis factor (TNF) levels were significantly higher in patients with CPA than in those with asthma (p < 0.05, Dunn’s multiple comparison test). The sensitivity and specificity of the IL-10/IL-5 ratio (cutoff index 2.47) for diagnosing CPA were 70% and 100%, respectively. The serum cytokine profile is useful in understanding the pathology of ABPA and CPA, and the IL-10/IL-5 ratio may be a novel supplemental biomarker for indicating the pathology of CPA.

Abstract
Although CD4+ T cells are recognized to play an important role in the inflammatory response of nasal polyps (NPs), the biological functions of CD8+ T cells in polypogenesis remain unclear. In this study, we analyzed cell markers, cytokine expression and transcription factors in IL-21-expressing CD8+ T cells in polyp tissues of NP patients. The results showed that the majority of IL-21-producing CD8+ T cells were effector memory cells and they co-expressed IFN-γ. IL-21-expressing CD8+ T cells in polyp tissues expressed higher CXCR5, PD-1, and ICOS levels than cells in control tissues and showed significantly higher T-bet and Bcl-6 expression levels compared with IL-21−CD8+ T cells. Purified polyp CD8+ T cells promoted IgG production from isolated polyp B cells in vitro, and recombinant IL-12 modulated the expression of IL-21, IFN-γ and CD40L in purified polyp CD8+ T cells. Moreover, the percentage of IL-21+CD8+ T cells in polyp tissues was positively correlated with endoscopic and CT scan scores in NP patients. These findings indicated that polyp CD8+ T cells, by co-expressing IL-21 and IFN-γ and other markers, display a Tfh cell functionality, which is associated with the clinical severity of NP patients.

Abstract
The injury of transplanted islets may occur by both autoimmune and alloimmune processes directed against MHC targets. To examine the role of MHC class I in islet graft injury, we transplanted syngeneic and allogeneic beta2-microglobulin-deficient islets into diabetic nonobese diabetic (NOD) mice. Loss of graft function was observed within 14 days using allogeneic C57BL/6 and BALB/c MHC class I deficient as well as wild-type MHC class I-bearing NOD donor islets. However, islets isolated from MHC class I-deficient NOD mice (NOD-B2 m-/-) survived indefinitely when transplanted under the kidney capsule of diabetic NOD recipients. Transplanted NOD-B2 m-/- islets were surrounded by a nondestructive periinsular infiltrate that expressed interleukin-4 in addition to interferon-gamma. These studies demonstrate the primary role of MHC class I molecules in causing autoimmune destruction or recurrent diabetes in transplanted islets.
