Description
We report that after cancer cells are exposed to a transient pulse (5h) of the pro-inflammatory cytokine IFN?, they continue up-regulating genes in the antigen presentation pathway for days after abrogation of the original signal. We discovered that a new mechanism of cell-to-cell communication, cytokine catch-and-release, explains this surprising result. Overall design: Examination of IFN?-induced gene expression over multiple timepoints in mouse melanoma cells

Description
RNAseq analysis of CD8 T cells becoming dysfunctional in progressing tumors. The overall goal of this study was to elucidate the molecular program that mediates functional unresponsiveness in tumor-specific CD8 T cells. In comparison, we also investigated CD8 T cells differentiating to functional effector and memory T cells during an acute listeria infection. Overall design: T cells were sorted by flow cytometry and RNA-seq was performed.

Description
Equine herpesvirus 1 (EHV-1) is a major pathogen affecting equines worldwide and causes respiratory disease, abortion, and in some cases, neurological disease.EHV-1strain KyA is attenuated in the mouse and equine, whereaswild-typestrain RacL11 induces severe inflammatory infiltration of the lung, causing infected mice to succumb at 4 to 6 days post-infection. Our previous results showed that EHV-1 KyA immunization protected CBA mice from pathogenic RacL11 challenge at 2 and 4 weeks post-immunization, and that the infection with theattenuatedKyA elicits protective humoral and cell-mediated immune responses.To investigate the protective mechanisms of EHV-1 KyA by innate immune responses, CBA mice immunized with live KyA were challenged with RacL11 at various timespost-vaccination. KyA immunization effectively protected CBA mice from RacL11 challenge at 1 to 7 dayspost-immunization. Immunized mice lost less than 10% of their preinfection body weight and rapidly regained body weight. Lung virus titers in EHV-1 KyA-immunized CBA mice were 1,000-fold lower at 2 days post-RacL11 challenge than lungs of non-immunized mice, which was indicative of accelerated virus clearance. Affymetrix microarray analysis revealed thatIFN-and16 antiviral interferon-stimulated genes (ISGs) were upregulated 3.1- to 48.2-fold at 8 h post-challengein the lungs of RacL11-challenged mice that had been immunized with KyA. Murine IFN-inhibitedEHV-1 infection of murine alveolar macrophage MH-S cells andeffectively protected mice against lethal EHV-1 challenge, suggesting that IFN-expression may be important in mediating protection elicited by KyA immunization. These results suggestthat EHV-1 KyA can be used asa live attenuated EHV-1 vaccine as well as a prophylactic agent in horses.

Description
Epigenetic changes are crucial for the generation of immunological memory1-4. Failure to generate or maintain these changes will result in poor memory responses. Similarly, augmenting or stabilizing the correct epigenetic states offers a potential method of enhancing immune memory. Yet the transcription factors that regulate these processes are poorly defined, as are the chromatin modifying complexes they recruit and the chromatin modifications they control. Using pathogen infection models and three different mouse models, including a new conditional allele, we find that the widely expressed transcription factor Oct15, and its cofactor OCA-B6,7, are selectively required the in vivo generation of functional CD4 memory. In vitro, both proteins are also required to maintain a poised state at the Il2 target locus in resting but previously stimulated CD4 T cells, and to generate robust Il2 expression upon restimulation. OCA-B is also required for the robust re-expression of other known targets including Il17a, and Ifng. We identify an underlying mechanism involving OCA-B recruitment of the histone lysine demethylase Jmjd1a8 to targets such as Il2 and Ifng. The findings pinpoint Oct1 and OCA-B as unanticipated mediators of CD4 T cell memory. Overall design: Examination of 4 different conditions in 2 genotypes
Publication Title
Oct1 and OCA-B are selectively required for CD4 memory T cell function.

Description
Microarrays were used to examine gene expression changes that may be present in the fallopian tube epithelium of morphologically normal BRCA1 mutation positive and negative subjects. Fallopian tube epithelia has been implicated as an early point of origin for serous carcninoma. By examining the early events present in the microenvironment of this tissue between BRCA1 mutation carriers and non-carriers, we hoped to elucidate mechanisms that may lead to the development of epithelial ovarian cancer.
