Project description:Adrenocortical cells get replenished throughout our lifetime and as such they are a cellular population of high interest in relation to adrenocortical tumours. Single cell transcriptomics of human adrenal gland were performed to identify rare subpopulations of cells, dynamics of cellular turnover and clone expansions in the adrenal cortex. The adrenal gland of this particular individual is characterized by the presence of mutant clone charecterized by aneuploidy in chromosomes 8, 9, 13 and 22, occupying the zona glomerulosa and zona fasciculata. Differential expression analysis of the mutant cells revealed upregulation of MC2R (adrenocorticotropic hormone receptor), CYP21A2, HSD3B2 genes (enzymes involved in cortisol production). Overall, this donor sample is an example of clonal tissue expansions carrying chromosomal rearrangements that likely impact organ morphology and function but are seemingly benign.

Project description:The adrenal cortex is characterized by a distinct architecture as well as a high density of specialized sinusoidal blood vessels. The preservation of this particular endothelial cell phenotype is likely vital for proper adrenal gland function. The aldosterone-producing zona glomerulosa harbors macrophages in close association with sinusoidal capillaries. However, the function of this macrophage-endothelial cell-juxtaposition in steady-state conditions is unknown. We show that macrophages preserve capillary specialization in the adrenal gland and modulate aldosterone secretion. By combining macrophage-specific deletion of the angiogenic cytokine Vascular Endothelial Growth Factor A (VEGF-A), single-cell transcriptomics and functional phenotyping, we provide evidence that loss of VEGF-A in myeloid cells, including adrenal gland macrophages depletes a specialized subset of PLVAP+ fenestrated endothelial cells in the zona glomerulosa of mice, along with increased deposition of basement membrane collagen IV and in

Project description:We discovered that wild yeast strains can tolerate extra chromosomes, a condition known as aneuploidy, whereas well-studied laboratory strains cannot. Understanding why some cells can tolerate aneuploidy and others cannot could have far-reaching impact, as for example, 85% of solid tumors are aneuploidy and often benefit from extra chromosomes, and thus identifying mechanisms of aneuploidy sensitization could have therapeutic applications.

Project description:The human adrenal gland consists of concentrically organized functionally distinct regions responsible for hormone production. Dysregulation of adrenocortical cell differentiation alters the proportion and organization of the functional zones of the adrenal cortex leading to disease. Current models of adrenocortical cell differentiation are based on mouse studies, but there are known organizational and functional differences between human and mouse adrenal glands. This study aimed to investigate the centripetal differentiation model in the human adrenal cortex and characterize aldosterone-producing micronodules (APMs) to better understand adrenal diseases such as primary aldosteronism. We applied spatially resolved in situ transcriptomics to human adrenal tissue sections from two individuals and identified distinct cell populations and their positional relationships. The results supported the centripetal differentiation model in humans, with cells progressing from the outer capsule to the zona glomerulosa, zona fasciculata, and zona reticularis. Additionally, we characterized two APMs in a 72-year-old female. Comparison with earlier APM transcriptomes indicated a subset of core genes, but also heterogeneity between APMs. The findings contribute to our understanding of normal and pathological cellular differentiation in the human adrenal cortex.

Project description:<p>Aneuploidy causes system-wide disruptions in the stochiometric balances of transcripts, proteins, and metabolites, often resulting in detrimental effects for the organism. The protozoan parasite Leishmania has an unusually high tolerance for aneuploidy, but the molecular and functional consequences for the pathogen remain poorly understood. Here, we addressed this question in vitro and present the first integrated analysis of the genome, transcriptome, proteome, and metabolome of highly aneuploid Leishmania donovani strains. Our analyses unambiguously establish that aneuploidy in Leishmania proportionally impacts the average transcript- and protein abundance levels of affected chromosomes, ultimately correlating with the degree of metabolic differences between strains. This proportionality was present in both proliferative and non-proliferative in vitro promastigotes. However, protein complex subunits and non-cytoplasmic proteins, showed dosage compensation, responding less or even not at all to aneuploidy-induced dosage changes. In contrast to other Eukaryotes, we did not observe the widespread regulation at the transcript level that typically modulates some of the negative effects of aneuploidy. Further, the majority of differentially expressed proteins between aneuploid strains were encoded by non-aneuploid chromosomes and were not driven by a significant underlying transcript change, suggesting that aneuploidy is accompanied by extensive post-transcriptional protein-level modulation. This makes Leishmania a unique Eukaryotic model for elucidating post-transcriptional protein-abundance modulation in the context of aneuploidy.</p><p><br></p><p><strong>Data availability:</strong></p><p>Proteomic data associated with this study are available in the PRIDE repository: accession number <a href='https://www.ebi.ac.uk/pride/archive/projects/PXD028521' rel='noopener noreferrer' target='_blank'>PXD028521</a>.</p>

Project description:Despite the ubiquitous function of macrophages across the body, the diversity, origin, and function of adrenal gland macrophages remain largely unknown. We defined the heterogeneity of adrenal gland immune cells using single-cell RNA sequencing and used genetic models to explore the developmental mechanisms yielding to macrophage diversity. We defined populations of monocyte-derived and embryonically seeded adrenal gland macrophages and identified a female-specific subset with low MHC-II expression. In adulthood, monocyte recruitment dominated adrenal gland macrophage maintenance in female mice, while self-proliferation was more important in males. Adrenal gland macrophage sub-tissular distribution followed a sex-dimorphic pattern, with MHC-IIlow macrophages located at the border between the cortex and the medulla. Macrophage sex dimorphism depended on the presence of the cortical Xzone. Forcing X-zone maintenance in males, or its degradation in females, directly impacted the presence of MHC-IIlow macrophages. Adrenal gland macrophage depletion resulted in altered tissue homeostasis, modulated lipid- metabolism and decreased local aldosterone production during stress exposure. Overall, these data explain the heterogeneity of adrenal gland macrophages and point toward sexrestricted distribution and functions of these cells.
