TL;DR: It is determined that short-chain fatty acids (SCFA), microbiota-derived bacterial fermentation products, regulated microglia homeostasis and mice deficient for the SCFA receptor FFAR2 mirroredmicroglia defects found under GF conditions, suggesting that host bacteria vitally regulate microglian maturation and function.

TL;DR: An automated massively parallel single-cell RNA sequencing approach for analyzing in vivo transcriptional states in thousands of single cells is introduced and provides the ability to perform a bottom-up characterization of in vivo cell-type landscapes independent of cell markers or prior knowledge.

TL;DR: It is shown that N6-methyladenosine (m6A), a messenger RNA (mRNA) modification present on transcripts of pluripotency factors, drives this transition from the pluripotent to the differentiated state.

TL;DR: A high-sensitivity indexing-first chromatin immunoprecipitation approach to profile the dynamics of four chromatin modifications across 16 stages of hematopoietic differentiation and reveals that lineage commitment involves de novo establishment of 17,035 lineage-specific enhancers.

TL;DR: These findings identify Trem2 signaling as a major pathway by which macrophages respond to loss of tissue-level lipid homeostasis, highlighting Trem2 as a key sensor of metabolic pathologies across multiple tissues and a potential therapeutic target in metabolic diseases.
