View SamplesReconstitution of cytomegalovirus (CMV)-specific immunity following transplant remains a primary clinical objective to prevent CMV disease, and adoptive immunotherapy of CMV-specific T cells can be an effective therapeutic approach. Due to the persistence of CMV, most CMV-specific CD8+ T cells become terminally differentiated effector cells (TEFF). However, a minor subset retains a memory phenotype (TM). Interestingly, recent studies suggest that CMV-specific CD8+ T cells with different phenotypes may have different abilities to reconstitute sustained immunity following transfer. The immunology of human CMV (HCMV) infections is reflected in the mouse model of MCMV infection. We found that HCMV- and MCMV-specific T cells displayed shared genetic programs, validating the MCMV model for studies of CMV-specific T cells in vivo. After transfer, the proliferative capacity of MCMV-specific TM cells was vastly superior to TEFF cells. Strikingly, TM cells expanded and established sustained and diverse T cell populations even after multiple challenges. Although both TEFF and TM cells could protect Rag-/- mice, only TM cells could consistently survive after transfer into immune replete, latently infected recipients and respond if recipient immunity was lost. These data show that CMV-specific TM cells retain memory function during persistent infection and can re-establish CMV immunity when necessary.
Memory T cells specific for murine cytomegalovirus re-emerge after multiple challenges and recapitulate immunity in various adoptive transfer scenarios.

View SamplesThe influenza A(H1N1)pdm09 virus caused a global flu pandemic in 2009 and contributes to seasonal epidemics. Different treatment and prevention options for influenza have been developed and applied with limited success. Here we report that an Akt inhibitor MK2206 possesses potent antiviral activity against influenza A(H1N1)pdm09 virus in vitro. We showed that MK2206 blocks the entry of different A(H1N1)pdm09 strains into cells. Moreover, MK2206 prevented A(H1N1)pdm09-mediated activation of cellular signaling pathways and the development of cellular immune responses. Importantly, A(H1N1)pdm09 virus was unable to develop resistance to MK2206. Thus, MK2206 is a potent anti-influenza A(H1N1)pdm09 agent.

View SamplesPrimary RNAseq data for 103 highly purified immunocyte populations representing all lineages and several differentiation cascades, profiled using the ImmGen ULI pipeline. Overall design: These RNAseq profiles were generated by ImmGen labs in a combined study associating RNAseq and ATACseq performed on cell populations sorted in parallel (companion ATACseq datasets are found in GSE100738). The 103 cell populations include all adaptive and innate lymphocytes (B, abT, gdT, Innate-Like Lymphocytes), myeloid cells (dendritic cells, macrophages, monocytes), mast cells and neutrophils. Most were prepared from baseline unchallenged mice, some after cell activation (LPS, anti-CD3, viral infection). For B and T lymphocytes, many successive steps of their known differentiation cascades in the thymus and bone marrow are included. ---------------------------------------- Immunological Genome Project Consortium

View SamplesIn human cells, Staufen1 is double-stranded RNA-binding protein involved in several cellular functions including mRNA localization, translation and decay. We used a genome wide approach to identify and compare the mRNA targets of mammalian Staufen1. The mRNA content of Staufen1 mRNPs was identified by probing DNA microarrays with probes derived from mRNAs isolated from immunopurified Staufen-containing complexes following transfection of HEK293T cells with a Stau1-HA expressor. Our results indicate that 7% of the cellular RNAs expressed in HEK293T cells are found in Stau1-containing mRNPs. There is a predominance of mRNAs involved in cell metabolism, transport, transcription, regulation of cell processes and catalytic activity.
A genome-wide approach identifies distinct but overlapping subsets of cellular mRNAs associated with Staufen1- and Staufen2-containing ribonucleoprotein complexes.

View SamplesIn human cells, Staufen2 is a double-stranded RNA-binding protein involved in several cellular functions. Although 51% identical to Staufen1, these proteins are nevertheless found in different RNA particles. In addition, differential splicing events generate Staufen2 isoforms that only differ at their N-terminal extremities. We used a genome wide approach to identify and compare the mRNA targets of mammalian Staufen2 isoforms. The mRNA content of Staufen mRNPs was identified by probing DNA microarrays with probes derived from mRNAs isolated from immunopurified Staufen2-containing complexes following transfection of HEK293T cells with Stau2-HA (59kDa) or Stau2-HA (62kDa) expressors. Our results indicate that 11% of the cellular RNAs expressed in HEK293T cells are found in Stau2-containing mRNPs. There is a predominance of mRNAs involved in cell metabolism, transport, transcription, regulation of cell processes and catalytic activity.
