Innate lymphoid cells (ILCs) are transcriptionally and functionally similar to T cells but lack adaptive antigen receptors. They play critical roles in early defense against pathogens. In this review, we summarize recent discoveries of ILC progenitors and discuss possible mechanisms that separate ILCs from T cells. We consider mechanisms of lineage...

T cells and innate lymphoid cells (ILCs) share expression of many key transcription factors during development and at mature stage, resulting in striking functional similarities between these lineages. Taking into account ILC contribution is thus necessary to appreciate T cell functions during immune responses. Furthermore, understanding ILC develo...

Microbes exhibit an extraordinary capacity to adapt their physiology to different environments using phenotypic heterogeneity. However, the majority of gene regulation studies are conducted in bulk reflecting only averaged gene expression levels across millions of cells. Bacterial single-cell RNA-seq (scRNA-seq) can overcome this by enabling whole ...

Single-cell studies are enabling our understanding of the molecular processes of normal cell development and the onset of several pathologies. For instance, single-cell RNA sequencing (scRNA-Seq) measures the transcriptome-wide gene expression at a single-cell resolution, allowing for studying the heterogeneity among the cells of the same populatio...

Recent advances have revolutionized the oldest high-throughput single-cell analytical tool, flow cytometry. Fluorescent analyzers and sorters with up to seven lasers and the potential to detect up to 50 parameters are changing the way flow cytometry is used, but old school practices which are inadequate for new technologies remain alive. This chapt...

Class I histone deacetylases (HDACs) are important regulators of cellular functions in health and disease. HDAC1, HDAC2, HDAC3, and HDAC8 are promising targets for the treatment of cancer, neurological, and immunological disorders. These enzymes have both catalytic and non-catalytic functions in the regulation of gene expression. We here describe t...

In eukaryotes, the organization of DNA wrapped around histones regulates DNA-dependent processes. Changes in epigenetic modifications modulate the compaction of DNA into chromatin and, thus, regulate DNA metabolism in time and space. Hence, to catalog the spatiotemporal epigenetic information and its relation to the dynamic nuclear landscape is of ...

Helicobacter pylori infection is one of the leading factors that promotes, among other diseases, gastric cancer (GC). Infection of gastric epithelial cells (GECs) by H. pylori enhances the expression as well as acetylation of the E3 ubiquitin ligase SIAH2 which promotes GC progression. The histone acetyltransferase (HAT) activity of p300 catalyzes ...

Reactive oxygen species (ROS) are induced by several chemotherapeutics. In this protocol, we describe a flow cytometry-based method for the analysis of the intracellular levels of ROS in vital leukemic cells in response to the histone deacetylase inhibitor vorinostat. This measurement of ROS using the cell-permeable dye CM-H2DCFDA indicates intrace...

During the preclinical development of small molecule inhibitors, compounds or compound libraries are typically first screened using purified target enzymes in vitro to select candidates with high potency. In the later stages of the development, however, functional cell-based assays may provide biologically more relevant data. In this chapter, we de...
