Description
Macrophages are a heterogeneous cell population involved in tissue homeostasis, inflammation and in multiple pathologies. Although the major tissue-resident macrophage populations have been extensively studied, interstitial macrophages (IMs) residing within tissue parenchyma remain poorly defined. Here, we studied IMs from murine lung, fat, heart and dermis. We identified two independent IM subpopulations that are conserved across tissues: Lyve1loMHCIIhiCX3CR1hi (Lyve1loMHCIIhi) and Lyve1hiMHCIIloCX3CR1lo (Lyve1hiMHCIIlo) monocyte-derived IMs, with distinct gene expression profiles, phenotypes, functions, and localisation. Using a mouse model of inducible macrophage depletion (SLCO2B1-DTR), we found that the absence of Lyve1hiMHCIIlo IMs exacerbated experimental lung fibrosis. Thus, we demonstrate that two independent populations of IMs exist across tissues and exhibit conserved niche-dependent functional programming. Overall design: Mouse Lung Interstitial Macrophages single cell mRNA profiles

Two distinct interstitial macrophage populations coexist across tissues in specific subtissular niches.

Description
Peripherally derived macrophages infiltrate the brain after bone marrow transplantation and during central nervous system (CNS) inflammation. It was initially suggested that these engrafting cells were newly derived microglia and that irradiation was essential for engraftment to occur. However, it remains unclear whether brain-engrafting macrophages (beMfs) acquire a unique phenotype in the brain, whether long-term engraftment may occur without irradiation, and whether brain function is affected by the engrafted cells. In this study, we demonstrate that chronic, partial microglia depletion is sufficient for beMfs to populate the niche and that the presence of beMfs does not alter behavior. Furthermore, beMfs maintain a unique functional and transcriptional identity as compared with microglia. Overall, this study establishes beMfs as a unique CNS cell type and demonstrates that therapeutic engraftment of beMfs may be possible with irradiation-free conditioning regimens. Overall design: Microglia were isolated from the brains of adult male c57BL/6 mice given bone marrow tranplants (BMT) with or without head shield. All mice received PLX5622 for 2 weeks, then placed and normal chow to recoever. Some mice were then challenged with LPS. Cells were isolated by MACS using CD11b magnetic beads.

Overall design: Mice were given 1000rad whole body irradiation, followed by bone marrow transplant with UBC-GFP bone marrow at 8 weeks of age. Engraftment was allowed to occur for 8 months, then engrafting macrophages and microglia were isolated from whole brains for RNA-Seq.

Description
The aim of this experiment was to investigate differential gene expression in splenocytes stimulated with BCG from nave and BCG vaccinated mice. The differences between nave and BCG vaccinated mice might indicate the mechanisms by which BCG vaccination confers an enhanced ability of splenocytes from BCG vaccinated mice to inhibit growth of BCG in splenocyte cultures as compared with splenocytes from naive animals.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Cortical development is a complex process involving the generation of neuronal progenitors, which proliferate and migrate to form the stratified layers of the maturing cortex. To identify microRNAs (miRNAs) and genes that may be important during early cortical development, we analyzed the expression profiles of rat neuronal progenitors obtained at embryonic day 11 (E11), E12 and E13 using microarrays. Neuronal progenitors were purified from telencephalic dissociates with a positive-selection strategy using surface labeling tetanus-toxin and cholera-toxin and fluorescence-activated cell sorting. We identified classes of miRNAs and mRNAs that were up-regulated or down-regulated in these neuronal progenitors as cortical development progressed from E11 to E13. We present data that supports a regulatory role for miRNAs during the transition from neuronal progenitors into differentiating cortical neurons.
