Description
We developed a technique for generating hypothalamic neurons from human pluripotent stem cells. Here, as proof-of-principle, we examine the use of these cells in modeling of a monogenic form of severe obesity: PCSK1 deficiency. We generated PCSK1 (PC1/3)-deficient human embryonic stem cell (hESC) lines using both shRNA and CRISPR-Cas9, and investigated pro-opiomelanocortin (POMC) processing using hESC-differentiated hypothalamic neurons. Overall design: We tried to idenitify transcripitional profiles and specific transcription factors that involved in of different stages during hypothalamic neuron differentiation from single cell sequencing for hESC-derived Day27 hypothalamic neurons, Day 12 neuron progenitors and undifferentiated stem cells

Description
The forkhead O transcription factors (FOXO) integrate a range of extracellular signals including growth factor signaling, inflammation, oxidative stress and nutrient availability, to substantially alter the program of gene expression and modulate cell survival, cell cycle progression, and many cell-type specific responses yet to be unraveled. Naive antigen-specific CD8+ T cells undergo a rapid expansion and arming of effector function within days of pathogen exposure, but in addition, by the peak of expansion, they form precursors to memory T cells capable of self-renewal and indefinite survival.

Differentiation of CD8 memory T cells depends on Foxo1.

- Affymetrix Maize Genome Array (maize)
Description
Ustilago maydis is a basidiomycete fungus that causes smut disease in maize. Most prominent symptoms of the disease are plant tumors, which can be induced by U. maydis on all aerial parts of the plant. We identified two linked genes, pit1 and pit2, which are specifically expressed during plant colonization. Deletion mutants for either pit1 or pit2 are unable to induce tumor development and elicit plant defense responses.
Publication Title
Two linked genes encoding a secreted effector and a membrane protein are essential for Ustilago maydis-induced tumour formation.

Description
During acute viral infections, nave CD8+ T cells differentiate into effector CD8+ T cells and, after viral control, into memory CD8+ T cells. Memory CD8+ T cells are highly functional, proliferate rapidly upon reinfection and persist long-term without antigen. In contrast, during chronic infections, CD8+ T cells become exhausted and have poor effector function, express multiple inhibitory receptors, possess low proliferative capacity, and cannot persist without antigen. To compare the development of functional memory T cells with poorly functional exhausted T cells, we generated longitudinal transcriptional profiles for each.

- Affymetrix Maize Genome Array (maize)
Description
Many of the genes coding for secreted protein effectors are arranged in gene clusters in the genome of the biotrophic plant pathogen Ustilago maydis. The largest of these gene clusters, cluster 19A, encodes 24 secreted effectors. Deletion of the entire cluster results in severe attenuation of virulence. The generation and analysis strains carrying sub-deletions identified 9 genes significantly contributing to tumor formation after seedling infection. As the individual contributions of these genes to tumor formation were small, we studied the response of maize plants to the whole cluster mutant as well as to several individual mutants by array analysis. This revealed distinct plant responses, demonstrating that the respective effectors have discrete plant targets.
