Project description:According to the WHO 2009 classification, dengue with warning signs (D+W) is at the risk of developing severe form of dengue disease. One of the most important warning signs is plasma leakage, which is a serious complication associated with higher morbidity and mortality. We report that the frequency of CD4+CD8+ double-positive (DP) T cells is significantly increased in patients at risk of developing plasma leakage. Transcriptomic analysis demonstrated that CD4+CD8+ DP cells were distinct from CD4+ Single Positive (SP) T cells, but co-clustered with CD8+ SP cells indicating a largely similar transcriptional profile. 20 significant differentially expressed (DE) genes were identified between CD4+CD8+ DP and CD8+ SP cells. These genes encode OX40 and CCR4 (TNFRSF4 and CCR4), as well as other molecules associated with cell signaling on the cell surface (NT5E, MXRA8, PTPRK). While 5 significant DE genes were identified, the profile of gene expression in CD4+CD8+ DP cells was mostly similar between patients with and without warning signs of plasma leakage, implying a role of CD4+CD8+ DP cells in plasma leakage through a quantitative increase rather than functional alteration. The differentially expressed genes identified could have diagnostic utility, perhaps as PCR-based diagnostic markers.

Project description:Aposematism and warning coloration are common defense strategies used by animals to deter predators. Pestilential gregarious locusts display a striking black-brown pattern, which is presumed to be a form of warning coloration compared to green solitary locusts. However, the specific mechanisms involved in regulating this distinctive pattern are not yet understood. Here, we found that different amounts of β-carotene and β-carotene-binding protein (βCBP) complexes confer the black tergum and brown sternum of locust. The expression level of βCBP is regulated by the bZIP transcription factor ATF2, which is activated by protein kinase C alpha (PKCα) in response to crowding. Specifically, ATF2 is phosphorylated at Ser327 and translocates to the nucleus, where it binds to specific sites on the βCBP promoter and stimulates overexpression. Differential phosphorylation of ATF2 resulted in the divergent black and brown body coloration of gregarious locusts. The overexpression of βCBP in the sternum is essential for the accumulation of red pigments, which creates the sharp contrast between the black tergum and the brown sternum. This spatial variation in ATF2 phosphorylation levels allows locusts to adapt to changing environmental conditions and better evade predation.

Project description:The development of predictive markers to determine the tipping point prior to the onset of osteoporosis is essential to mitigate further irrevocable deterioration. In order to determine the early warning signs before osteoporosis, we used the dynamic network biomarker (DNB) approach to analyze the time series gene expression data in the zebrafish osteoporosis model and revealed that cyclin-dependent kinase inhibitor 1A (cdkn1a) is one core member of DNB. We demonstrated that cdkn1a negatively regulates osteogenesis, evidenced by the loss-of-function and gain-of-function studies. On one hand, CRISPR/Cas9-mediated cdkn1a knockout in the zebrafish significantly altered skeletal development and increased bone mineralization. On the other hand, inducible cdkn1a expression significantly contributed to the osteoclast differentiation. We also provide mechanistic clues that cdkn1a participates in osteoclast differentiation by regulating its upstream signaling cascades. Our data provided new insights into the dynamic nature of osteoporosis, and identified cdkn1a as the early-warning signals of osteoporosis onset.

Project description:Plant defence against insects is well known to be affected by previous exposure to cues warning of herbivory. Using Arabidopsis thaliana and the herbivore Pieris brassicae, we addressed the question whether the maintenance of the effects of the warning cue depends on its reliability. We determined the transcriptomes of Arabidopsis leaves that were treated by P. brassicae egg deposition (i) five days after oviposition, (ii) one day after removal of the eggs following the egg treatment, (iii) three days after removal of the eggs, (iv) after two days of herbivory that started one day after removal of the eggs; or that were treated by chilling (v) five days after transfer to 4°C, (vi) one day after transfering the plants to 20°C following the chilling treatment, (vii) three days after transfering the plants to 20°C, (viii) after two days of herbivory that started one day after transfering the plants to 20°C.
