Psoriasis is a chronic skin disease mediated by Th17 and/or Th1 cells. Tim-3 is a cell surface molecule preferentially expressed on Th17 and Th1 cells. The interaction of Tim-3 with Tim-3 ligand inhibits cytokine production. To assess whether T cells in psoriasis have functional abnormalities, expression of cell surface Tim-3 on blood T cells producing interleukin-17 (Th17/Tc17 cells) or interf...

Down syndrome is a common disorder associated with intellectual disability in humans. Among a variety of severe health problems, patients with Down syndrome exhibit disrupted sleep and abnormal 24-h rest/activity patterns. The transchromosomic mouse model of Down syndrome, Tc1, is a trans-species mouse model for Down syndrome, carrying most of human chromosome 21 in addition to the normal compl...

The pond snail Lymnaea stagnalis learns and forms long-term memory (LTM) following both operant conditioning of aerial respiratory behavior and classical conditioning of taste aversive behavior. In the present study, we examined whether there are interstrain differences in the ability to form LTM following these two types of conditioning. A strain of Lymnaea (TC1) collected in Alberta, Canada e...

CD8(+) T cells are important effectors, as well as regulators, of organ-specific autoimmunity. Compared with Tc1-type CD8(+) cells, Tc2 cells have impaired anti-viral and anti-tumor effector functions, although no data are yet available on their pathogenic role in autoimmunity. Our aim was to explore the role of autoreactive Tc1 and Tc2 cells in autoimmune diabetes. We set up an adoptive transf...

A neutral mononuclear Fe(II) complex with spin crossover (SCO) properties, Fe2(SCN)2 (1) (L = 2-(2-(trifluoromethyl)phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline), was solvothermally synthesized. It displays a new example of two-step SCO with Tc1↓ = 250 K, Tc1↑ = 260 K and Tc2 = 295 K.

A free-living ciliate, Trimyema compressum, found in anoxic freshwater environments harbors methanogenic archaea and a bacterial symbiont named TC1 in its cytoplasm. Here, we report the complete genome sequence of the TC1 symbiont, consisting of a 1.59-Mb chromosome and a 35.8-kb plasmid, which was determined using the PacBio RSII sequencer.

The Tc1 transposable element family of the nematode Caenorhabditis elegans consists primarily of 1.6-kb size elements. This uniformity of size is in contrast to P in Drosophila and Ac/Ds in maize. Germline transposition and excision of Tc1 are detectable in the Bergerac (BO) strain, but not in the commonly used Bristol (N2) strain. A previous study suggested that multiple genetic components are...

Established EG7 tumors expressing OVA and growing at an intradermal site become rapidly reduced in size following adoptive therapy with in vitro-generated type I CD8 T cell (Tc1) effectors generated from naive CD8 T cells from transgenic TCR OVA-specific mice. Tc1 effectors kill EG7 target cells in vitro by a perforin-dependent mechanism. However, we show that there is no quantitative diminutio...

The principal antitumor immune response is mediated through the activation of type 1 cytotoxic (Tc1) CD8 T cells, NK cells, and monocytes/macrophages. In this study, we investigated the potency of a clinical-grade soluble form of lymphocyte activation gene-3 protein (IMP321), a physiological high-affinity MHC class II binder, at inducing in PBMCs an appropriate cytotoxic-type response in short-...
