Targeting the IL-12/IL-23 axis
Combination immune checkpoint blockade has demonstrated significant clinical responses in cancers infiltrated by T cells. Many tumors contain high proportions of myeloid cells and these can secrete immunosuppressive cytokines like IL-23. Our data suggest the clinical potential of using anti-CD40 (push) and anti-IL-23 mAbs (pull) to tip the IL-12/23 balance in established tumors and act as an al...
متن کاملMorphine disrupts interleukin-23 (IL-23)/IL-17-mediated pulmonary mucosal host defense against Streptococcus pneumoniae infection.
Streptococcus pneumoniae is a pathogen that causes serious respiratory disease and meningitis in the immunocompromised drug abuse population. However, the precise mechanisms by which drug abuse compromises the host immune defense to pulmonary S. pneumoniae infection is not fully understood. Using a well-established murine model of opiate abuse and S. pneumoniae lung infection, we explored the i...
متن کاملIL-23 enhances host defense against vaccinia virus infection via a mechanism partly involving IL-17.
To investigate roles of IL-23 in viral infection, we have engineered recombinant vaccinia virus (VV) expressing IL-12 (VV-IL-12) and expressing IL-23 (VV-IL-23). We found VV-IL-23 was less virulent in BALB/c mice than wild-type VV (VV-WT), indicating that IL-23 enhances resistance to VV. VV-specific CTL activity in VV-IL-23-infected mice was slightly higher than activity in VV-WT-inoculated mic...
متن کاملDivergent roles of IL-23 and IL-12 in host defense against Klebsiella pneumoniae
Interleukin (IL)-23 is a heterodimeric cytokine that shares the identical p40 subunit as IL-12 but exhibits a unique p19 subunit similar to IL-12 p35. IL-12/23 p40, interferon gamma (IFN-gamma), and IL-17 are critical for host defense against Klebsiella pneumoniae. In vitro, K. pneumoniae-pulsed dendritic cell culture supernatants elicit T cell IL-17 production in a IL-23-dependent manner. Howe...
متن کاملGut reaction
The image above shows immunofluorescence staining of a cross-section of small intestine from a mouse with a 'mosaic' pattern of expression of cell-surface MHC (major histocompatibility complex) class I molecules. The mosaic effect can be seen on the intestinal villi, which contain stretches of epithelial cells that express MHC class I (bright green) interrupted by equally long stretches of cell...
