UNLABELLED T-cell immunoglobulin and mucin domain 1 (TIM-1) and other TIM family members were recently identified as phosphatidylserine (PtdSer)-mediated virus entry-enhancing receptors (PVEERs). These proteins enhance entry of Ebola virus (EBOV) and other viruses by binding PtdSer on the viral envelope, concentrating virus on the cell surface, and promoting subsequent internalization. The PtdS...
The Period (PER), Timeless (TIM), and Double-Time (DBT) proteins are essential components of one feedback loop in the Drosophila circadian molecular clock. PER and TIM physically interact. Coexpression of PER and TIM promotes their nuclear accumulation and influences the activity of DBT: although DBT phosphorylates and destabilizes PER, this is suppressed by TIM. Experiments using Drosophila ce...
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...
Although melanoma vaccines stimulate tumor antigen-specific CD8(+) T cells, objective clinical responses are rarely observed. To investigate this discrepancy, we evaluated the character of vaccine-induced CD8(+) T cells with regard to the inhibitory T-cell coreceptors PD-1 and Tim-3 in patients with metastatic melanoma who were administered tumor vaccines. The vaccines included incomplete Freun...
BACKGROUND Although Tim-3 & PD-L1 signaling pathways play important roles in negatively regulating immune responses, their roles in chlamydial infection have not been evaluated. METHODS Neutralization antibodies targeting Tim-3 and PD-L1 were used to treat mice. Following an intravaginal infection with C. muridarum organisms, mice with or without the dual antibody treatment were compared for ...
The incidence of cardiovascular disease, including inflammatory heart diseases like myocarditis, is increased in men. Similarly, male BALB/c mice infected with coxsackievirus B3 (CVB3) develop more severe acute inflammation in the heart compared to females. To better understand the effect of male sex hormones on cardiac inflammation, we gonadectomized (Gdx) male BALB/c mice and examined acute C...
