AI Article Synopsis
- * Female C57BL/6 mice were irradiated and then received hematopoietic stem cells from male BALB/c donors, with DLI given either IV or via IBM.
- * Results showed that IBM-DLI significantly reduced both the frequency and severity of GVHD compared to IV-DLI, with an increase in IL-4 levels and a decrease in IFN-gamma in the IV group.
Article Abstract
To investigate the effect of donor lymphocyte infusion (DLI) by intra-bone marrow (IBM) routes on the incidence of graft-versus-host disease(GVHD), level of IL-4 and IFN-gamma after allogeneic peripheral hematopoietic stem cell transplantation (allo-PBSCT). Female C57BL/6 mice as recipients received total body irradiation (TBI) on day 0, followed by injection of peripheral hematopoietic stem cells from mobilized donor of male BALB/c with the granulocyte-colony stimulating factor (rhG-CSF), and DLI was performed via ether IV or IBM routes. The severity of GVHD was compared in recipients received allogeneic IBM-DLI with those mice received IV-DLI; at 14 days after DLI, the levels of IL-4 and interferon (IFN)-gamma were tested by ELISA. The results showed that as compared with IV-DLI group the frequency and severity of GVHD were reduced in IBM-DLI (p < 0.01); the level of IL-4 significantly increased, while the level of IFN-gamma decreased in group IV-DLI (p < 0.01). It is concluded that IBM-DLI declines the incidence and severity of GVHD after allo-PBSCT.

Swine influenza virus invades the host through the respiratory mucosa, which severely restricts the development of the pig breeding industry. To construct monomeric and trimeric vaccines, we developed recombinant Escherichia coli Nissle 1917 (EcN) strains that express the receptor binding site (RBS) of the hemagglutinin (HA) antigen from H1N1 swine influenza virus. After the mucosal immunization of mice, we found that probiotics activated CD40 and CD86 in DCs and increased the levels of IL-4 and IFN-γ secretion by T cells.

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).
