It has been reported that the proinflammatory cytokine IL-6, which is upregulated upon H. pylori infection in the gastric mucosa, contributes to gastric tumorigenesis [ 68].
It has been reported that several proinflammatory Th1 cytokines, including interferon- (INF-) γ, tumor necrosis factor- (TNF-) β and interleukin- (IL-) 2, and anti-inflammatory Th2 cytokines like IL-4 and IL-10, as well as leukaemia inhibitory factor (LIF), are related to programmed cell death (PCD).
Additional factors may be physiological: it has been reported that an increase in proinflammatory cytokines may be a possible contributor to primary fatigue in MS [ 40, 42].
10, 22 Moreover, it has been reported that the production of proinflammatory cytokines is higher in abdominal fat than in subcutaneous fat, whereas aromatase activity and adiponectin secretion are lower in visceral than in subcutaneous fat.
Consistent with these clinical outcomes, it has been reported that macrophage infiltration and proinflammatory endothelial cytokine expression remained unchanged in arthroscopic biopsies of RA synovial tissues after intra-articular administration of corticosteroids [ 31].
It has been reported that monocytes secrete various proinflammatory cytokines, such as interleukin (IL -1, IL -1 IL-60, and tumor necrosis factor-α (TNF-α), which hand been associatumorith short survival anecrosisprognosis in patients with malignancy [ 32, 33].
Although it has been reported that many chemokines and proinflammatory cytokines induce the infiltration of inflammatory cells (mainly mononuclear cells and T cells) into the synovium of inflamed joints and thus mediate inflammation [ 10, 11], the etiology of RA remains unknown.
Although the etiology of RA remains unknown, it has been reported that a functional imbalance between proinflammatory cytokines and regulatory T cells (Tregs) is a key mechanism that underlies joint inflammation and disease progression in CIA as well as RA [ 3].
It has been reported that Angpt-2 promotes the proinflammatory activation of human macrophages in RA synovial tissue and that the neutralization of this molecule in an in vivo model of RA decreased disease severity, inflammation, neovascularisation, and joint destruction [ 100].
