The combination of CpG ODN with cGAMP is a potent type 1 adjuvant, capable of inducing strong Th1 type responses, as demonstrated by enhanced antigen-specific IgG2c and IFN-γ production, as well as cytotoxic CD8+ T-cell responses.

In our murine tumor models, intra-tumoral injection of CpG ODN and cGAMP together reduced tumor size significantly compared with the singular treatments, acting as an antigen-free anti-cancer agent. Thus, the combination of CpG ODN and a STING ligand may offer therapeutic application as a potent type II IFN inducer. This article is protected by copyright. All rights reserved “
“Cholestasis can cause translocation of gut bacteria, and endotoxemia, and systemic inflammation. Now, little is known about the effects of cholestasis on the testicular inflammation and autophagy. A rat biliary cholestasis model caused by common bile duct ligation (CBDL), together with biliary decompression (choledochoduodenostomy), was find more used. The magnitude of MCP-1 expression and CD68+ macrophage infiltration within testes was progressively up-regulated in rats PD-0332991 chemical structure along with increasing duration of CBDL and was maintained at relatively high level in rats with biliary decompression. The large up-regulation of testicular ATG-12, LC3II, and autophagic vacuoles was found with the extending duration of

CBDL and kept at 5 weeks following biliary decompression. The autophagic contents were a large accumulation of mitophagy in testes in rats with CBDL, and cytosol learn more components in rats with biliary decompression. Secondary biliary cholestasis can promote inflammatory reaction and the activation of mitophagy and autophagy in testes. “
“The production of allergen-specific IgE antibodies (Abs) in allergen-sensitized patients or animals has a mutual relationship with the immunologic response leading to allergic rhinitis. We recently reported that, after an intranasal injection of cedar pollen into mice, an interleukin-4 (IL-4)-dependent increase in serum nonspecific IgE Abs was a prerequisite for the

production of serum allergen-specific IgE Abs. Here, we explored which lymphoid organs were responsive to the intranasally injected allergen and how IL-4 and IgE Abs were produced in the lymphocytes. Time-dependent changes in the total cell numbers and in in vitro IgE Ab production in various lymphoid organs revealed that the submandibular lymph nodes were the main responsible organ. After treatment with allergen (for IgE production) or allergen and complete Freund’s adjuvant (for IgG production), we separated submandibular lymph node cells into macrophage-, lymphocyte-, and granulocyte-rich populations by discontinuous Percoll density-gradient centrifugation. Unexpectedly, bulk cells, but not the lymphocyte- or macrophage-rich populations, produced significant amounts of IL-4, IgE, and IgG; whereas production was restored by addition of Mac-1+ cells from the macrophage-rich to the lymphocyte-rich fraction.
