Objective: In this study, expression of Interleukin-2, Interleukin-4, Interleukin-10 and transforming growth factor beta in diffuse and intestinal type gastric cancers from Mexican patients was assessed for use as markers of malignancy. Methods: A total of 30 biopsies from gastric adenocarcinomas, 60% diffuse, 20% intestinal and 20% mixed in type, were studied by immunohistochemistry. Results: Regarding expression of cytokines, 23% were positive for IL-2, 26.7% for IL-4, 16.6% for IL-10 and none for TGF-β. There were found Significant statistically stage differences were noted.For example, for stages I-II 100% were IL-2 positive (p = 0.009), 87.5% were IL-4 positive (p = 0.005) and 100.0% IL-10 positive (p = 0.009). Young women were more likely to suffer gastric adenocarcinoma. In biopsies of male patients with gastric cancer, there was an increased expression of IL-2 and in biopsies from female patients in IL4. There was significantly greater detection of IL-4 and IL-10 expression in stages I and II than in stages III and IV. It was also found that IL-4, IL-10 had a higher positive expression in patients biopsies with low-level differentiations than patients with well differentiated gastric cancer in which cases were undetected. Conclusions: These results suggest that positive expression of IL-4 and IL-10 may be useful as a molecular marker to distinguish stage I and II diffuse gastric cancers which can be more readily controlled.

Myasthenia gravis (MG) is a T cell-dependent, B cell-mediated disorder strongly associated with antigen presentation by dendritic cells (DCs). In MG, mucosal tolerance is linked to increased expression of TGF-β mRNA in monocytes. Additionally, monocytic myeloid-derived suppressor cells (M-MDSCs) exhibit negative immunomodulatory effects by suppressing autoreactive T and B cells.

: Cytokines related to the Th17 response have been associated with peri-implant diseases; however, the effect of peri-implant therapy on their modulation remains underexplored. To evaluate the effect of peri-implant therapy on the expression of cytokines related to the Th17 response in the peri-implant crevicular fluid (PICF) (GM-CSF, IFN-γ, IL-1β, IL-4, IL-6, IL-10, IL-12 (p70), IL-17A, IL-21, IL-23, and TNF-α) of partially edentulous patients with peri-implant disease (PID). : Thirty-seven systemically healthy individuals presenting with peri-implant mucositis (PIM) (n = 20) or peri-implantitis (PI) (n = 17) were treated and evaluated at baseline (T0) and three months after therapy (T1).

can modulate host immune mechanisms through excretory-secretory products (ESP). As one of the components of ESP, it is unknown whether Abelson tyrosine protein kinase (Abl) is involved in parasite-host immune interaction. To investigate the immunoregulatory function of Abl in , we cloned and expressed the gigantica Abl protein and assessed its effect on specific immune functions of buffalo peripheral blood mononuclear cells (PBMCs).

Chronic venous disease (CVD) comprises a set of vascular disorders that affect the venous system with important local and systemic repercussions. A growing body of evidence displays the relationship between suffering from CVD and a marked deregulation of the immune inflammatory system. In this sense, the previous literature has reported some significant changes in the level of various circulating inflammatory parameters in these patients.

Fucoidan is a natural sulfated polysaccharide with immunoregulatory function. In this work, the anti-allergic impacts of Gracilaria lemaneiformis fucoidan (GLF) in mitigating allergic reactions induced by shrimp tropomyosin were investigated. As the results, GLF performed significant hyaluronidase inhibition ability (IC = 0.
