(Submitter supplied) The human brain is populated by perivascular CD8+ and CD4+ T cells with a tissue-resident memory T (TRM)-cell phenotype. In multiple sclerosis (MS), these cells associate with white matter (WM) and, to a lesser extent, grey matter (GM) lesions. We here investigated the transcriptional and functional profile of brain-resident T cells. Of n=11 subsequent post-mortem brain donors, we isolated CD8+ and CD4+ effector memory and effector memory re-expressing CD45RA T cells from blood and CD8+ and CD4+ CD69+ T cells from corpus callosum WM and cortical GM. more...

(Submitter supplied) Delineating the origins and properties of antibodies elicited by SARS-CoV-2 infection and vaccination is critical for understanding their benefits and potential shortcomings. Therefore, we investigated the SARS-CoV-2 spike (S)-reactive B cell repertoire in unexposed individuals by flow cytometry and single-cell sequencing. We found that ~82% of SARS-CoV-2 S-reactive B cells show a naive phenotype, which represents an unusually high fraction of total human naive B cells (~0.1%). more...

(Submitter supplied) Retinal photoreceptors undergo daily renewal of their distal outer segments, a process indispensable for maintaining retinal health. Photoreceptor Outer Segment (POS) phagocytosis occurs as a daily peak, roughly about one hour after light onset. However, the underlying cellular and molecular mechanisms which initiate this process are still unknown. Here we show that, under constant darkness, mice deficient for core circadian clock genes (Per1 and Per2), lack a daily peak in POS phagocytosis. more...

(Submitter supplied) Endocrine therapy is the most used treatment for hormone receptor positive breast cancers. Despite the clear benefit of endocrine therapy for patients with ER+ breast cancer, resistance to treatment is a critical clinical issue affecting a large number of patients. While many studies have shown that genetics is an important factor in therapy resistance, recent publications have also reported that epigenetics might play a major role in the acquisition of resistance to endocrine therapies. more...

(Submitter supplied) RNA expression was profiled in B-cell lymphoma cell lines treated with CC0483115 (CC-115) using strand-specific RNA-sequencing. The following cell lines were tested: GRANTA (mantle cell lymphoma, resistant to CC-115), JEKO (mantle cell lymphoma, sensitive), Jiyoye (Burkitt lymphoma, resistant), RAMOS (Burkitt lymphoma, sensitive), RPMI8226 (multiple myeloma (MM), sensitive), and U-266 (MM, resistant).

(Submitter supplied) Slowing down mRNA translation in either the cytoplasm or the mitochondria are both conserved longevity mechanisms. Here, we found a non-interventional natural correlation of mitochondrial and cytoplasmic ribosomal proteins when looking at mouse population genetics, suggesting a mito-cytoplasmic translational balance. Additionally, inhibiting mitochondrial translation in C. elegans in turn reduced cytoplasmic translation and repressed growth pathways while upregulating stress responses at both proteome and transcriptome levels. more...

(Submitter supplied) Animal studies have linked disturbed adipose tissue clock gene rhythms to the pathophysiology of the metabolic syndrome. However, data on molecular clock rhythms in human patients are limited. Therefore, in a standardized real life setting, we compared diurnal gene expression profiles in subcutaneous adipose tissue between obese patients with type 2 diabetes and age-matched healthy lean control subjects, using RNA sequencing. more...

(Submitter supplied) Inhibition of the costimulatory CD40-CD40L receptor/ligand dyad drastically reduces atherosclerosis. However, its long-term blockage can result in immune suppression. We recently identified small molecule inhibitors that block the interaction between CD40 and TNF Receptor Associated Factor (TRAF) 6 (TRAF-STOPs), while leaving CD40-TRAF2/3/5 interactions intact, thereby preserving CD40-mediated immunity. more...

(Submitter supplied) Resident memory T-cells (TRM) reside in the lung epithelium and mediate protective immunity against respiratory pathogens. While lung CD8+ TRM have been extensively characterized, the properties of CD4+ TRM remain unclear. Here we determined the transcriptional signature of CD4+ TRM, identified by the expression of CD103, retrieved from human lung resection material. Various tissue homing molecules were specifically upregulated on CD4+ TRM, while expression of tissue egress and lymph node homing molecules were low. more...

(Submitter supplied) Cardiovascular disease (CVD) is the leading cause of human morbidity and mortality worldwide, underscoring the need to improve diagnostic strategies. Monocytes play a major role in the initiation, propagation, and progression of CVD. MicroRNAs are endogenous small non-coding RNAs that control gene expression and are expressed in a tissue and disease-specific manner. Therefore they have been proposed to be useful biomarkers. more...

(Submitter supplied) Age-related macular degeneration is a progressive disease resulting in impaired central vision. Degeneration of the retinal pigmented epithelial (RPE) monolayer is associated with the progression of the disease. To date no treatment is able to stop this progression, however new cell replacement studies using human embryonic stem cells (hESC) to generate RPE show a promising prospective. To improve cell replacement strategies a better understanding about the development of RPE cells is necessary. more...

(Submitter supplied) Degeneration of the RPE leads to severe vision loss in, so far incurable, diseases such as age-related macular degeneration and some forms of retinitis pigmentosa. A promising future replacement therapy may be autologous iris epithelial cell transdifferentiation into RPE in vitro and, subsequently, transplantation. In this study we compared the gene expression profiles of the iris epithelium (IE) and the RPE.We compared the gene expression profiles of RPE and IE.

(Submitter supplied) Protective interactions with bystander cells in micro-environmental niches such as lymph nodes (LNs) contribute to survival and therapy resistance of chronic lymphocytic leukemia (CLL) cells. This is caused by a shift in expression of BCL-2 family members. Pro-survival proteins BCL-XL, BFL-1, and MCL-1 are upregulated by LN-residing T cells through CD40L interaction, presumably via NF-κB signaling. Macrophages also reside in the LN, and are assumed to provide important supportive functions for CLL cells. However, if and how macrophages are able to induce survival is incompletely known. We first established that macrophages induced survival due to an exclusive upregulation of MCL-1. Next, we investigated the mechanism underlying MCL-1 induction by macrophages in comparison with CD40L. Genome-wide expression profiling of in vitro macrophage- and CD40L-stimulated CLL cells indicated activation of the PI3K-AKT-mTOR pathway, which was confirmed in ex vivo CLL LN material. Inhibition of PI3K-AKT-mTOR signaling abrogated MCL-1 upregulation and survival by macrophages as well asCD40 stimulation. MCL-1 can be regulated at multiple levels, and we established that AKT leads to increased MCL-1 translation, but does not affect MCL-1 transcription or protein stabilization. Furthermore, among macrophage-secreted factors that could activate AKT, we found that induction of MCL-1 and survival critically depended on C-C Motif Chemokine Receptor-1 (CCR1). In conclusion, this study indicates that two distinct micro-environmental factors, CD40L and macrophages, signal via CCR1 to induce AKT activation resulting in translational stabilization of MCL-1, and hence can contribute to CLL cell survival.

(Submitter supplied) Purpose: Severe late normal tissue damage limits radiotherapy treatment regimens. This study aims to validate γ-H2AX foci decay ratios and induced expression levels of DNA double strand break (DSB) repair genes, found in a retrospective study, as possible predictors for late radiation toxicity. Methods and Materials: Prospectively, decay ratios (initial/residual γ-H2AX foci numbers) and genome-wide expression profiles were examined in ex vivo irradiated lymphocytes of 198 prostate cancer patients. more...
