Project description:9 rabbit spleen label free proteomics studies.In order to study some drugs on animal innate immunity, we built rabbit models, using rabbit immune organs - spleen made mass spectrometry based label free proteomics studies. Finally, it is expected to find the target of the drug and the mechanism of action.

Project description:Non-myelinating glia in visceral organs have not been well characterized. It Is likekely they have uniqe functions in the organs in which they reside. This is interesting in immune organs such as the spleen in which glia ensheath nerves that come in close contact with immune cells. However, glia in the spleen have not been well characterized. We report here an in-depth anatomical and transcriptional characterization of spleen glia.

Project description:Lactococcus garvieae is the etiological agent of lactococcosis, a hemorrhagic septicaemia that affects marine and freshwater fish, with special incidence and economic relevance in farmed rainbow trout and with potential zoonotic risks. To characterize the trout immune response at the transcriptomic level on those individuals with clinical signs of lactococcosis, we have performed a microarray analysis using a previously validated immune-focused gene design. The analysis of the transcriptome of spleen and kidney reveals a different pattern of transcription between both immune organs. A correlation between the histopathological examination and the expression patterns of gene sets characterizing immune cell populations was observed for the first time in the spleen. Up-regulation of gene sets key to NK cells, cytotoxic T cells, Th1 and Th2 lymphocytes and macrophages correlated with the inflammatory process and the existence of granulomes containing a high number of macrophages with internalized L. garvieae. On the other hand, cell wall peptidoglican seems to be an important antigen able to induce a complex network of pathways, cytokine production and responses in the host.

Project description:The immunotoxicity of PFOS (perfluorooctane sulfonate) were reported previously, however, the detailed toxic mechanism remain unknown. Spleen is an important immune organ that controls the differentiation and development of immune cells including T cells, B cells, and macrophages etc. the disruption of the organ may result in altered immune functions and immunotoxicity. We used microarrays to snapshot the changes of global gene expression, and identified target genes underlying the immunotoxicity of PFOS exposure. 6-8 week old Balb/c female mice were exposed to 10mg/kg body weight PFOS per day for 3 weeks through intragastric administration, and then spleens were removed for RNA extraction and hybridization on Affymetrix microarrays. By comparing the gene expression of spleens with or without PFOS exposure, we sought to obtain differentially expressed genes in order to reveal the toxic mechanism of PFOS.

Project description:Leukocyte infiltration accelerates brain injury following intracerebral hemorrhage (ICH). But the involvement of T lymphocytes in this process has not been fully elucidated.To further depict the landscape of the composition and functional states of brain-infiltrating immune cells following ICH, single-cell RNA sequencing was performed to compare the molecular characteristics of CD45+ cells from brain and spleen tissues in ICH and control mice.Our results revealed that brain-infiltrating T cells exhibited enhanced pro-inflammatory and pro-apoptotic signatures.

Project description:The effect of dietary immunostimulation in the immune organs, head kidney and spleen, of rainbow trout (Oncorhynchus mykiss), was investigated using a salmonid-specific microarray platform enriched with immune-related genes. Immunostimulant-diet feeding significantly changed transcriptomic expression profiles: larger reduction rather than induction was observed, with significant regulation in genes and functional GO categories related to remodeling processes and immune and hematopoietic activities. The results revealed that Immunostimulant-diets hava effect in the transcriptome of cultured fish. Keywords: spleen, head kidney, immunostimulats, transcriptomic response, trout

Project description:Niemann-Pick Type C (NPC) disease is a rare, genetic, lysosomal disorder with progressive neurodegeneration. Poor understanding of the pathophysiology and lack of blood-based diagnostic markers are major hurdles in the treatment and management of NPC and several additional neurological, lysosomal disorders. To identify disease severity correlates, we undertook whole genome expression profiling of sentinel organs, brain, liver, and spleen of Balb/c Npc1-/- mice (Npc1nih)relative to Npc1+/- at an asymptomatic stage, as well as early- and late-symptomatic stages. Unexpectedly, we found prominent up regulation of innate immunity genes with age-dependent change in their expression, in all three organs. We shortlisted a set of 12 secretory genes whose expression steadily increased with age in both brain and liver, as potential plasma correlates for the neurological disease. Ten were innate immune genes with eight ascribed to lysosomes. Several are known to be elevated in diseased organs of murine models of other lysosomal diseases including GaucherM-bM-^@M-^Ys disease, Sandhoff disease and MPSIIIB. We validated the top candidate lysozyme, in the plasma of Npc1-/- as well as Balb/c Npc1nmf164 mice (bearing a point mutation closer to human disease mutants) and show its reduction in response to an emerging therapeutic. We further established elevation of innate immunity in Npc1-/- mice through multiple functional assays including inhibition of bacterial infection as well as cellular analysis and immunohistochemistry. We used microarrays on the diseased organs, brain, liver and spleen of the Npc1-/- mice to unserstand the molecular changes occur during the progression of NPC diseases. From the data, we have identified 12 potential genes which can be potentially developed as blood-based biomarker. We have also discovered up regulation of innate iimunity genes in all three organs of Npc1-/- mice and functionally validated them in liver and spleen. Brain from 11 female Npc1M-bM-^HM-^R/M-bM-^HM-^R and 16 control female mice (Npc1+/+ and Npc1+/M-bM-^HM-^R) from 6 age groups (20-25, 37-40, 54-55, 59-62, 67-71 and 81-84 days) were surgically harvested. Liver and spleen from 6 Npc1-/- and 6 Npc1+/- female mice from three age group ( 20-25, 54-55 and 67-71 days) were surgically harvested. Organs were kept in RNA later and stored at -20 M-BM-0C until used. RNA was isolated and Affymetrix mouse 430 2.0 array hybridizations were performed by M-bM-^@M-^XUCLA Clinical Microarray CoreM-bM-^@M-^Y, UCLA, Los Angeles, CA, USA. Subsequent raw data were analyzed using DNA-Chip Analyzer (D-Chip) with the .CEL files obtained from AGCC. Data from Npc1-/- mice from all age groups were compared to control mice (Npc1+/- and/or Npc1-/- mice) from all age groups separately for brain, liver and spleen. 'Matrix Table1' corrsponds for brain, 'Matrix Table2' corresponds for liver and 'Matrix Table3' corresponds for spleen. Thresholds for selecting significant genes were set at a relative difference M-BM-31.5-fold, absolute difference M-BM-3100 signal intensity units and p<0.05. Genes that met all three criteria simultaneously were considered as significant change.
