RNA-seq reveals the immuno-modulation of exosomes in Zhikong scallop Chlamys farreri

ABSTRACT: As marine invertebrates, scallops lack adaptive immunity and employ innate immunity as the front line and almost the solo defense mechanism to protect them against invaders. Accumulating research achievements demonstrated that exosomes could act as innate immune effectors that contribute to host defense mechanism. To better understand the immune functions of exosomes in Chlamys farreri, mRNA profiles of hemocytes from scallops injected with PBS, with normal exosomes and LPS stimulating exosomes, respectively, were generated by deep sequencing, in triplicate.

Exosomal shuttle protein in Pacific oyster Crassostrea gigas during bacterial stimulation

Project description:As marine invertebrates, oysters lack adaptive immunity and employ innate immunity as the front line and lmost the solo defense mechanism to protect them against invaders. Accumulating research achievements demonstrated that exosomes could act as innate immune effectors that contribute to host defense mechanism. To better understand the immune functions of exosomes in Crassostrea gigas against bacterial stimulation, iTRAQ was applied to explore the global protein changes of exosomes in oyster after Staphylococcus aureus and Vibrio splendidus stimulation.

Integrated transcriptomics and metabolomics reveal tolerance mechanisms to hypoxia stress in Yesso scallop, Mizuhopecten yessoensis

Project description:Global warming and human activities have led to an increased frequency of hypoxia in coastal regions. Hypoxia not only affects the growth and development of scallops but can also cause death, posing a significant challenge to the health and sustainability of aquaculture. Its effects on scallop growth and immune system have been widely reported, but studies on the effects of hypoxic stress on the metabolism of Yesso scallop Mizuhopecten yessoensis are not fully understood. Additionally, the molecular mechanisms of hypoxic stress on damage to the Yesso scallop are still limited. In this study, we deploy high-throughput RNA sequencing (RNA-Seq) and non-targeted liquid chromatography-mass spectrometry (LC-MS) based metabolomics analysis to investigate the alterations in key genes and metabolites in scallops after 24 hours of hypoxia stress (DO: 1 ± 0.1 mg/L). A total of 704 differentially expressed genes (DEGs) and 302 differentially expressed metabolites (DEMs) were identified in the gill tissues of Yesso scallops under hypoxic conditions, respectively. DEGs and DEMs were involved in energy metabolism, antioxidant responses, immune responses, and inflammatory responses, as well as processes of cell apoptosis and cell proliferation. KEGG enrichment analysis shows that the mTOR signaling pathway is a significantly enriched pathway shared by DEGs and DEMs. These findings suggest that Yesso scallops cope with acute hypoxic stress by changing energy metabolism, inhibiting cell apoptosis and proliferation, and increasing immune defense strategies. Overall, the results of this study provide a new understanding of how Yesso scallops respond to hypoxia and provide target genes for the selection and breeding of low-oxygen-tolerant scallops.

Gene Expression in Arabidopsis thaliana Guard Cells

Project description:Stomata are formed by a pair of specialized guard cells that control the opening and closing of the stomatal pores on the leaf surface. These pores are the main route for microbe penetration into leaves. However, plants show a remarkable ability to close the pore when sensing the presence of microbial invaders; a phenomenon recently described as stomatal immunity. This study was initiated to understand the transcriptional regulation of this early plant defense against pathogens.

Inflammation and degeneration of the olfactory epithelium in an immuno-deficient zebrafish

Project description:Vertebrates are protected from pathogens by an adaptive and an innate immune system. In mammals, loss of the adaptive immune system severely compromises viability. Zebrafish, in contrast, can survive for relatively long without adaptive immunity, as demonstrated by the immuno-deficient Rag1 mutant. Here, we examine whether the innate immune system is activated in the mutant, and ask whether this has any effect on the nervous system, given the finding that inflammation is linked to neurodegeneration in higher vertebrates. Using microarray analysis of the olfactory epithelium, we show that innate immune responses are upregulated. Neuronal genes are down-regulated, and immunofluorescence for the neural marker HuC shows a progressive loss of olfactory sensory neurons in mutants. Propodium iodide uptake indicates a corresponding increase in cell death. Rag1 mutant fish progressively lose their sensitivity to an olfactory cue, the alarm pheromone Schreckstoff, indicating that neuro-degeneration has a behavioral significance. Taken together, these data establish that immuno-deficiency in the zebrafish is accompanied by neuro-inflammation and loss of neurons. The microarray data document transcriptional changes associated with activation of innate immunity in the context of immunodeficiency and also identify novel genes that are potentially related to function of the olfactory system. Keywords: analysis of mutant A total of 6 RNA samples were used for hybridization. 3 were from the olfactory rosettes of wild type adult zebrafish and 3 were from Rag1 mutants.

Expression data from BMDC cells with or without Sendai virus infection

Project description:Innate immunity is the first line of defense against viral and microbial pathogens. BMDC is critical for innate immunity. To investigate the complicated net signaling after virus invasion, we did a cDNA microarray analysis of BMDC with or without Sendai Virus infection. We used microarrays to find proteins that upregulated by Sendai Virus infection and investigated if these proteins had functions in regulating Sendai Virus induced signaling pathway. BMDC cells are seperated from C57BL6 mice, infected with Sendai Virus or not,cultured and harveseted for RNA extraction and hybridization on Affymetrix microarrays
