We describe a fully automated pipeline for the morphometric phenotyping of mouse brains from μMRI data, and show its application to the Tc1 mouse model of Down syndrome, to identify new morphological phenotypes in the brain of this first transchromosomic animal carrying human chromosome 21. We incorporate an accessible approach for simultaneously scanning multiple ex vivo brains, requiring only...
A novel transposon named ITmD37E was discovered in a wide range of mosquito species. Sequence analysis of multiple copies in three Aedes species showed similar terminal inverted repeats and common putative TA target site duplications. The ITmD37E transposases contain a conserved DD37E catalytic motif, which is unique among reported transposons of the IS630-Tc1-mariner superfamily. Sequence comp...
Various chemokines and cytokines as adjuvants can be used to improve efficacy of DNA vaccination. In this study, we sought to investigate if a DNA construct expressing IL-9 (designed as proV-IL9) as a molecular adjuvant enhance antigen specific immune responses elicited by the pcD-VP1 DNA vaccination. Mice immunized with pcD-VP1 combined with proV-IL9 developed a strong humoral response. In add...
Down Syndrome (DS) is a highly prevalent developmental disorder, affecting 1/700 births. Intellectual disability, which affects learning and memory, is present in all cases and is reflected by below average IQ. We sought to determine whether defective morphology and connectivity in neurons of the cerebral cortex may underlie the cognitive deficits that have been described in two mouse models of...
CD8 T cell-mediated immune responses fall into two distinct types based on effector cell-derived cytokine production. Type I CD8 T cells (Tc1) produce IFN-gamma, whereas type 2 cells (Tc2) secrete IL-4, IL-5, IL-10, and GM-CSF. Using a murine TCR transgenic T cell/breast tumor model, we show that adoptively transferred Ag-specific Tc1 cells are more effective in delaying mammary tumor growth an...
RATIONALE The prevalence of Alzheimer's disease is increased in people with Down syndrome. The pathology appears much earlier than in the general population, suggesting a predisposition to develop Alzheimer's disease. Down syndrome results from trisomy of human chromosome 21, leading to overexpression of possible Alzheimer's disease candidate genes, such as amyloid precursor protein gene. To be...
Notable changes in the molecular conformations of 4-chlorobenzyl alcohol around the C(H2)-Car and O-C(H2) bonds were found to take place at the first-order phase transition point (Tc1 = 236 K). Quite similar phenomena were observed at Tc1 (217 K) of the isomorphic 4-bromo compound. The two kinds of conformational changes are considered to couple and cause the reversal of the direction of the li...
Cytolytic CD8+ effector cells fall into two subpopulations based on cytokine secretion. Type 1 CD8+ T cells (Tc1) secrete IFN-gamma, whereas type 2 CD8+ T cells (Tc2) secrete IL-4, IL-5, and IL-10. Using an OVA-transfected B16 lung metastases model, we assessed the therapeutic effects of adoptively transferred OVA-specific Tc1 and Tc2 subpopulations in mice bearing established pulmonary maligna...
Arthrobacter sp. strains are among the most frequently isolated, indigenous, aerobic bacterial genera found in soils. Member of the genus are metabolically and ecologically diverse and have the ability to survive in environmentally harsh conditions for extended periods of time. The genome of Arthrobacter aurescens strain TC1, which was originally isolated from soil at an atrazine spill site, is...
Allergic contact dermatitis (ACD) is the result of an exaggerated immune reaction to haptens mediated by skin-homing T cells, but the effector mechanisms responsible for the tissue damage are poorly understood. Here we studied the capacity of distinct subsets of hapten-specific T cells to induce apoptosis in autologous keratinocytes. Skin- and blood-derived nickel-specific CD8+ T cytotoxic 1 (T...
