- Description
- Description: This 23dcdp monoclonal antibody reacts with the p19 subunit of human IL-23. This heterodimeric cytokine is composed of two disulfide-linked subunits, p40 and p19. It is closely related to IL-12, with which it shares the p40 subunit. The IL-23 receptor is also heterodimeric and shares the IL-12Rbeta1 chain with IL-12, while the IL-23R chain is unique to the IL-23 receptor complex. IL-23R signaling occurs through the Jak/STAT pathway and results in RORgammat expression, which promotes maintenance and proliferation of T helper 17 (Th17) cells.

- Intracellular staining of unstimulated (left) or LPS-stimulated and monensin-treated (right), in vitro-cultured human dendritic cells with Anti-Human IL-12/23 p40 PE (Product # 12-7235-42) and Anti-Human IL-23 p19 eFluor® 660. Cultures were fixed and permeabilized with the Fixation and Permeabilization Kit (Product # 88-8823-88). Total viable cells as determined by staining with the Fixable Viability Dye eFluor® 450 (Product # 65-0863-14) were used for analysis. Data from two donors are shown to illustrate variability in expression.

- Figure 11 MPhi isolated from fiber-high colonic tissue express diminished IL23 levels. RNA sequencing was performed on sorted viable colonic MPhi and blood-derived M1 and M2 MPhi. ( A ) PCA plot shows similarity between the different populations based on their first 2 principal components. The top 500 genes, selected by highest row variance, were used. Fiber-low ( green , n = 4); fiber-high ( blue , n = 5); muscle ( red , n = 3); M1 ( black , n = 3); M2 ( gray , n = 3). ( B ) Normalized sequence reads of selected macrophage-related genes. Scatter plots with bar show means +- standard error of the mean. ( C ) Global transcriptional changes between macrophages isolated from fiber-low colonic tissue and fiber-high colonic tissue visualized by a volcano plot. Comparison of gene expression between the groups of samples was performed with the package DESeq2. The Wald test was used to generate P values and log2 fold changes. Genes with an adjusted P value
