The timeless mutation (tim) leads to loss of circadian behavioral rhythms in Drosophila melanogaster. The effects of tim on rhythmicity involve interactions with period (per), a second essential clock gene, as the tim mutation suppresses circadian oscillations of per transcription and blocks nuclear localization of a PER reporter protein. In the present study it was found that the tim mutant co...

CD4+ T cells contribute to the pathogenesis of ischemia-reperfusion injury, which is the primary cause of delayed graft failure after kidney transplantation. The TIM-1:TIM-4 pathway participates in the activation/differentiation of CD4+ T cells, suggesting that it may modulate ischemia-reperfusion injury. Here, we studied the role of TIM-1 in a murine uninephrectomized renal ischemia-reperfusio...

T cell immunoglobulin and mucin-4 (TIM-4), mainly expressed on antigen presenting cells, plays a versatile role in immunoregulation. CD1d-restricted invariant natural killer T (iNKT) cells are potent cells involved in the diverse immune responses. It was recently reported that recombinant TIM-4 (rTIM-4) alone enhanced cytokine production in NKT hybridoma, DN32.D3 cells. Hence, we hypothesized t...

Light is the dominant environmental cue that provides temporal information to circadian pacemakers. In Drosophila melanogaster some period gene mutants have altered free-running circadian periods but entrain to 24 h light-dark cycles. To address the mechanism of light entrainment in Drosophila, we examined the effects of constant light on the period gene (per) and timeless gene (tim) products i...

T-cell immunoglobulin domain and mucin domain-containing molecule-3 (Tim-3) was up-regulated on viral specific T cells and contributed to T cells exhaustion during chronic hepatitis B virus (HBV) infection. However, modulation of Tim-3 expression was still not fully elucidated. To evaluate the potential viral and inflammatory factors involved in the inductor of Tim-3 expression on T cells, 76 p...

T cell immunoglobulin and mucin domain-containing molecule-3 (Tim-3) is a surface molecule that is preferentially expressed on activated Th1 cells in comparison to Th2 cells. Blockade of Tim-3 has been shown to enhance Th1-driven pathology in vivo, suggesting that blockade of Tim-3 may improve the development of Th2-associated responses such as allergy. To examine the effects of Tim-3 blockade ...

Circadian clocks responsible for daily time keeping in a wide range of organisms synchronize to daily temperature cycles via pathways that remain poorly understood. To address this problem from the perspective of the molecular oscillator, we monitored temperature-dependent resetting of four of its core components in the fruitfly Drosophila melanogaster: the transcripts and proteins for the cloc...

Antisera against the circadian clock proteins Period (PER) and Timeless (TIM) were used to construct a detailed time course of PER and TIM expression and subcellular localization in a subset of the ventrolateral neurons (vLNs) in the Drosophila accessory medulla (AMe). These neurons, which express pigment-dispersing factor, play a central role in the control of behavioral rhythms. The data reve...

Triosephosphate isomerase (TIM) is an essential, highly conserved component of glycolysis. Tumors are often dependent on glycolysis for energy and metabolite production (the Warburg effect). Glycolysis inhibitors thus show promise as cancer treatments. TIM inhibition, unlike inhibition of other glycolysis enzymes, also produces toxic methylglyoxal targeted to regions of high glycolysis, an effe...

The molten carbonate fuel cell (MCFC) has evolved to current megawatt-scale commercial power plants. When using the fuel cell for electrolysis (MCEC), it provides a promising option for producing fuel gases such as hydrogen, via water electrolysis, and syngas, via co-electrolysis of water and carbon dioxide. The molten carbonate cell can thereby operate reversibly as a dual energy converter for...
