Breast cancer (BC) is the most frequent tumour affecting women all over the world. In low- and middle-income countries, where its incidence is expected to rise further, BC seems set to become a public health emergency. The aim of the present study is to provide a systematic review of current BC screening programmes in WHO European Region to identify possible patterns. Multiple correspondence analysis was performed to evaluate the association among: measures of occurrence; GNI level; type of BC screening programme; organization of public information and awareness campaigns regarding primary prevention of modifiable risk factors; type of BC screening services; year of screening institution; screening coverage and data quality...

The origin of the thymic epithelium, i.e. the cortical (cTEC) and medullary (mTEC) epithelial cells, from bipotent stem cells through TEC progenitors and lineage-specific progeny still remains poorly understood. We sought to obtain an unbiased view of the incipient emergence of TEC subsets by following embryonic TEC development based on co-expression of EpCAM, CD80 and MHC class II (MHCII) on non-hematopoietic (CD45(-) ) thymic stromal cells in wild-type BL6 mice. Using a combination of ex vivo analysis, Re-aggregate Thymic Organ Culture (RTOC) reconstitution assays and mathematical modelling, we traced emergent lineage commitment in murine embryonic TECs...

Fas ligand drives insulitis in the non-obese diabetic mouse model of type 1 diabetes (T1D) and negatively regulates IL-10-producing (IL-10(pos)) CD5(+) B cells in pancreata. Relevance of these phenomena to the human disease is poorly understood. Here, using splenocytes from T1D, autoantibody (Ab(+)), and non-diabetic (ND) human subjects, we show that a subpopulation of CD5(+) B cells that is characterized by expression of FasL (FasL(hi)CD5(+)) was significantly elevated in T1D subjects, many of whom had significantly reduced frequency of IL-10(pos)CD5(+) B cells compared to Ab(+) subjects...

Endogenous cannabinoids (endocannabinoids) are small molecules biosynthesized from membrane glycerophospholipid. Anandamide (AEA) is an endogenous intestinal cannabinoid that controls appetite and energy balance by engagement of the enteric nervous system through cannabinoid receptors. Here, we uncover a role for AEA and its receptor, cannabinoid receptor 2 (CB2), in the regulation of immune tolerance in the gut and the pancreas. This work demonstrates a major immunological role for an endocannabinoid. The pungent molecule capsaicin (CP) has a similar effect as AEA; however, CP acts by engagement of the vanilloid receptor TRPV1, causing local production of AEA, which acts through CB2...

It remains unclear whether activated inflammatory macrophages can adopt features of tissue-resident macrophages, or what mechanisms might mediate such a phenotypic conversion. Here we show that vitamin A is required for the phenotypic conversion of interleukin 4 (IL-4)-activated monocyte-derived F4/80(int)CD206(+)PD-L2(+)MHCII(+) macrophages into macrophages with a tissue-resident F4/80(hi)CD206(-)PD-L2(-)MHCII(-)UCP1(+) phenotype in the peritoneal cavity of mice and during the formation of liver granulomas in mice infected with Schistosoma mansoni...

Chromosome conformation capture-based methods such as Hi-C have become mainstream techniques for the study of the 3D organization of genomes. These methods convert chromatin interactions reflecting topological chromatin structures into digital information (counts of pair-wise interactions). Here, we describe an updated protocol for Hi-C (Hi-C 2.0) that integrates recent improvements into a single protocol for efficient and high-resolution capture of chromatin interactions. This protocol combines chromatin digestion and frequently cutting enzymes to obtain kilobase (Kb) resolution...

BACKGROUND: Cellular targets of neonatal hypoxia-ischemia (HI) include both oligodendrocyte and neuronal lineages with differences in the patterns of vulnerable cells depending upon the developmental stage at which the injury occurs. Injury to the developing white matter is a characteristic feature of human preterm brain injury. Data are accumulating, however, for neuronal injury in the developing cerebral cortex. In the most widely used rodent model of preterm HI brain injury, conflicting data have been reported regarding the sensitivity of subplate neurons to early neonatal HI, with some reports of selective vulnerability and others that find no increased loss of subplate neurons in comparison with other cortical layers...

BACKGROUND: Langerhans cells (LCs) are one of the initial target cells for HIV following sexual exposure and they are productively infected by HIV. HIV-infected LCs migrate to the draining lymph nodes (dLNs) and transmit the virus to CD4(+) T cells, leading to the dissemination of HIV. In contrast with the role of LCs in initial HIV acquisition, little is known about the modulation of immune responses by HIV-infected LCs. OBJECTIVE: We aimed to elucidate the induction of HIV-specific CD8(+) T cells and regulatory T cells (Tregs), both of which play important roles in regulating the progression of HIV infection...

BACKGROUND: T regulatory cells (Tregs) are known to negatively control immune response. The frequency of these cells was inversely correlated with clinical outcomes of breast cancer. CD19(+)CD24(hi)CD38(hi) cells also play a critical role in inflammation and autoimmune disease. However, their function in tumor immune response is less studied. In this study we aimed to determine the role of CD19(+)CD24(hi)CD38(hi) cells and some other clinicopathological variables in increasing the proportion of Tregs in breast cancer patients...

Recent Hi-C measurements have revealed numerous intra- and inter-chromosomal interactions in various eukaryotic cells. To what extent these interactions regulate gene expression is not clear. This question is particularly intriguing in budding yeast because it has extensive long-distance chromosomal interactions but few cases of gene regulation over-a-distance. Here, we developed a medium-throughput assay to screen for functional long-distance interactions that affect the average expression level of a reporter gene as well as its cell-to-cell variability (noise)...

BACKGROUND: Hypoxia-ischemia (HI) is a major cause of neurological damage in preterm. Pregnancy swimming alters the pup's brain development. We tested the effects of swimming during pregnancy in the very immature rat brain. METHODS: Female Wistar rats (n=12) were assigned to sedentary (SE, n=6) or swimming groups (SW, n=6). From the gestational day 0 (DG0) to GD21 they performed 20 min/daily swimming sessions. HI on postnatal day 3 rat cause sensorimotor and cognitive impairments...

The structural and functional basis of the genome is provided by the three-dimensional (3D) chromatin state. To enable accurate gene regulation, enhancer elements and promoter regions are brought into close spatial proximity to ensure proper, cell type-specific gene expression. In cancer, genetic and epigenetic processes can deregulate the transcriptional program. To investigate whether the 3D chromatin state is also disrupted in cancer we performed Hi-C chromosome conformation sequencing in normal and prostate cancer cells and compared the chromatin interaction maps with changes to the genome and epigenome...

The spleen plays an integral protective role against encapsulated bacterial infections. Our understanding of the associated mechanisms is limited to thymus-independent (TI) antibody production by the marginal zone (MZ) B cells, leaving the contribution of other splenic compartments such as the red pulp (RP) largely unexplored despite asplenic patients succumbing to the infection in the first 24 h, suggesting important antibody-independent mechanisms. In this study, using time-lapse intravital imaging of the spleen, we identify a tropism for Streptococcus pneumoniae in this organ mediated by tissue-resident MZ and RP macrophages and a protective role for two distinct splenic neutrophil populations (Ly6G(hi) and Ly6G(intermediate)) residing in the splenic RP...

BACKGROUND: Although the dopamine precursor L-3, 4-dihydroxyphenylalanine ( l -dopa) remains the gold standard pharmacological therapy for patients with Parkinson's disease (PD), long-term treatment with this drug has been known to result in several adverse effects, including l -dopa-induced dyskinesia (LID). Recently, our group reported that KD5040, a modified herbal remedy, had neuroprotective effects in both in vitro and in vivo models of PD. Thus, the present study investigated whether KD5040 would have synergistic effects with l -dopa and antidyskinetic effects caused by l -dopa as well...
