“…These factors are closely associated with various gut inflammatory diseases or gut health. T Helper (Th) Cells (T helper type 1 (Th1; IFN-γ, IL-2, and TNF-β; Wang J. et al, 2018 ; Pradhan et al, 2019 ), Th2 (IL-4, IL-5, IL-9, IL-10, IL-13, IL-25, IL-31, and IL-33; Pradhan et al, 2019 ), Th9 (IL-9, IL-10, IL-21, IL-33, and IL-36; Hoeppli et al, 2019 ), Th17 (IL-6, IL-8, IL-17A, IL-17F, IL-21, IL-22, and IL-26; Kulkarni et al, 2018 ; Wang J. et al, 2018 ; Alrafas et al, 2019 ), Th22 (IL-13, IL-22, IL-26 and TNF-α; Sanaii et al, 2019 ; Shohan et al, 2020 ) and regulatory T (Treg) cells (IL-10, TGF-β and IL-35; Kulkarni et al, 2018 ; Alrafas et al, 2019 ) are involved with gut inflammation ( Figure 2A ). The effects of AOS on these cells or cytokines are explored.…”
