CD29 identifies IFN-γ–producing human CD8+ T cells with an increased cytotoxic potential

Project description:Cytotoxic CD8+ T cells can effectively kill target cells by producing cytokines, chemokines, and granzymes. Expression of these effector molecules is however highly divergent, and tools that identify and preselect CD8+ T cells with a cytotoxic expression profile are lacking. Human CD8+ T cells can be divided into IFN-γ– and IL-2–producing cells. Unbiased transcriptomics and proteomics analysis on cytokine-producing fixed CD8+ T cells revealed that IL-2+ cells produce helper cytokines, and that IFN-γ+ cells produce cytotoxic molecules. IFN-γ+ T cells expressed the surface marker CD29 already prior to stimulation. CD29 also marked T cells with cytotoxic gene expression from different tissues in single-cell RNA-sequencing data. Notably, CD29+ T cells maintained the cytotoxic phenotype during cell culture, suggesting a stable phenotype. Preselecting CD29-expressing MART1 TCR-engineered T cells potentiated the killing of target cells. We therefore propose that CD29 expression can help evaluate and select for potent therapeutic T cell products.

Rat insulin-producing INS-1E exposed to cytokines IL-1β and IFN-γ

Project description:In the context of T1 Diabetes, pro-inflammatory cytokines IL-1β and IFN-γ are known to contribute to β-cell apoptosis; The measurement of mRNA expression following β-cell exposure to these cytokines gives a picture of the changes in gene expression characterizing the path to β-cell dysfunction and death. INS1 cell lines were cultured in medium with or without IL-1β and IFN-γ. The samples were collected at various time points for profiling with Affymetrix Rat ST arrays. These experiments were performed on two separate occasions.

The effects of terbutaline or GW9508 on TNF-alpha and IFN gamma (TNF-alpha + IFN gamma) stimulation by HaCaT

Project description:G-protein coupled receptors (GPCRs) have diverse roles in physiological processes, including immunity. Gs-coupled GPCRs increase while Gi-coupled ones decrease intracellular cAMP. Previous studies suggest that, in epithelial cells, Gs-coupled GPCRs enhance whereas Gi-coupled GPCRs suppress pro-inflammatory immune responses. In order to examine the issue, we chose beta2 adrenergic receptor and GPR40 as representatives of Gs- and Gi- coupled GPCRs, respectively, and examined their effects on TNF-alpha and IFN-gamma-(TNF-alpha + IFN-gamma) induced gene expression by HaCaT. We used microarrays to detail the global changes of gene expression induced by a beta2 adrenergic receptor agonist terbutaline or GPR40 agonist GW9508 pre-treatment in TNF-alpha + IFN-gamma - stimulated HaCaT cells. HaCaT cells were pre-treated with terbutaline or GW9508, TNF-alpha + IFN-gamma were then added, and cultured for another 24 h. Cells were then used for RNA extraction and hybridization on Affymetrix microarrays. We sought to clarify changes in gene expression after 1) TNF-alpha + IFN-gamma, 2) TNF-alpha + IFN-gamma + terbutaline, and 3) TNF-alpha + IFN-gamma + GW9508 treatment. To this end, we set 4 groups of samples; 1) unstimulated group, 2) TNF-alpha + IFN-gamma-stimulated group, 3) TNF-alpha + IFN-gamma + terbutaline-stimulated group, and 4) TNF-alpha + IFN-gamma + GW9508-stimulated group. In each group, HaCaT cells were stimulated in triplicate wells (n=3).

Interferon (IFN)-γ promotes monocyte-mediated lung injury during influenza pathogenesis

Project description:Influenza A Virus (IAV) triggers an exuberant host response that promotes acute lung injury. However, the determinants of the pathological host response to IAV remain incompletely understood. In the current study, we identified interferon (IFN)-γ-regulated subset of monocytes, CCR2+ monocytes, as a driver of lung damage during IAV pathogenesis. IFN-γ regulated the recruitment and inflammatory phenotype of CCR2+ monocytes, and CCR2 (CCR2-/-) and IFN-γ (IFN-γ-/-) deficient mice exhibited reduced lung inflammation, pathology, and increased resistance against bacterial co-infection by Streptococcus pneumoniae (Spn). Adoptive transfer of WT (IFN-γR1+), but not IFN-γR1 deficient (IFN-γR1-) CCR2+ monocytes, restored the wild-type (WT)-like pathological phenotype of lung damage in IAV-infected CCR2-/- mice. The CD8+ T cells were the most significant source of IFN-γ in IAV-infected lungs. Collectively, our data highlight that IFN-γ regulates CCR2+ monocyte-mediated lung pathology during IAV pathogenesis.

Molecular signature of hepatitis B virus regulation by IFN-γ in primary human hepatocyte

Project description:Hepatitis B virus (HBV) infection is a risk of developing fibrosis, cirrhosis, liver failure, and hepatocellular carcinoma. Although HBV elimination requires complete elimination of covalently closed circular DNA (cccDNA), its treatment has not been established. Interferon (IFN) -γ, a type ⅠⅠ IFN, is produced by intrahepatic cytotoxic T lymphocytes and has the noncytolytic antiviral potential. However, the mechanism by which IFN-γ regulates HBV infection in hepatocytes has not been fully elucidated. In this study, to replicate the HBV infection and monitor the amount of cccDNA, we developed an in vitro HBV infection assay system with primary hepatocytes and examined the molecules and signaling pathways. IFN-γ suppressed both HBV propagation and transcription to the same extent as IFN-α. RNA microarray analysis revealed that IFN-γ stimulation induced not only IFN-γ but also IFN-α signaling activation and regulated HBV cccDNA. Moreover, the HBV production was reduced by IFN-γ through JAK-STAT signaling and interferon stimulated genes such as OAS2 and APOBEC3G. Taken together, these results demonstrate that IFN-γ suppresses both HBV propagation and transcription by activating specific intracellular signaling pathways in hepatocytes and suggests the future application of this particular signaling pathways or genes for the complete elimination of HBV.
