Rationale: Restoration of coronary artery blood flow is the most effective means ameliorating myocardial damage triggered by ischemic heart disease. However, reperfusion elicits an increment additional injury to myocardium. Accumulating evidence indicates that unfolded protein response (UPR) in cardiomyocytes activated ischemia/reperfusion (I/R) injury. Xbp1s (spliced X-box binding 1), highly conserved branch response, protective cardiac I/R GRP78 (78 kDa glucose-regulated protein), a master...

Cytolytic effectors polarize toward target cells for effective killing and IFN-γ secretion. The spatiotemporal features of this polarization their importance cytolysis have not been resolved. In cytotoxic T natural killer (NK) cells, transient was consistently associated with killing. Polarization regulated by Cdc42, a small Rho family GTPase universally critical cytoskeletal dynamics. Transient accumulation active Cdc42 at the cytolytic effector/target cell interface focus such on center...

Activation of naïve T cells requires synergistic signals produced by the T-cell receptor (TCR) and CD28. We previously identified novel adaptor ALX, which, upon overexpression in Jurkat cells, inhibited activation interleukin-2 (IL-2) promoter TCR/CD28, suggesting that it is a negative regulator activation. To further understand physiological role ALX-deficient mice were generated. Purified from demonstrated increased IL-2 production, CD25 expression, proliferation response to TCR/CD28...

The herb holy basil (Ocimum tenuiflorum) is rich in essential oil, which important pharmaceutical, nutraceutical, cosmetic, and food industries. O. tenuiflorum grows well tropical, subtropical, warm temperate regions. To induce oil biosynthesis, plants were exposed to cold or drought stress for 5 days. Gas chromatography-mass spectrometry (GC–MS) analyses revealed that components including eugenol, methyl β-caryophyllene significantly accumulated 30-day-old juvenile 130-day-old pre-flowering...

Abstract Adaptors play a critical role in regulating signaling pathways that control lymphocyte development and activation. Adaptor lymphocytes of unknown function X (ALX) Rlk/Itk-binding protein (RIBP) are adaptors related by structure sequence, coexpressed T cells. Mice deficient for each adaptor demonstrated ALX RIBP, respectively, negatively positively regulate cell activation response to TCR/CD28 stimulation. However, these results did not preclude they may redundantly other...

Abstract The activation of T cells and the initiation an immune response is tightly controlled through crosstalk both positive negative regulators. Two adaptors that function as regulators cell are adaptor in lymphocytes unknown X (ALX) linker for (LAX). Previously, we showed from mice deficient ALX LAX display similar hyperresponsiveness, with increased IL-2 production proliferation upon TCR/CD28 stimulation, these physically associate. In this study, analyze nature association between LAX....

Abstract Parasitic nematodes cause significant morbidity and mortality globally. Excretory/secretory products (ESPs) such as fatty acid- retinol- binding proteins (FARs) are hypothesized to suppress host immunity during infection, yet little is known about their interactions with tissues. Leveraging the insect parasitic nematode, Steinernema carpocapsae , we provide first in vivo study that shows FARs modulate animal immunity, causing an increase susceptibility bacterial infection. Next...

Abstract T cell development depends on the coordinated interplay between receptor signaling and transcriptional activation/repression. We performed a genetic complementation screen, identified novel repressor, NKAP. NKAP associates with HDAC3 is part of DNA-binding complex, as shown by chromatin immunoprecipitation. also CIR, Notch corepressor complex. The expression during inversely correlates target genes, implying that may modulate Notch-mediated transcription. To examine function in...

Natural killer (NK) cells and cytotoxic T lymphocytes (CTLs) are central immune effectors. They activate in a cellular interaction with target cells, leading to cell lysis IFN? secretion. These effector functions require effective polarization. We have therefore studied roles of Cdc42 Rac, two general regulators polarization, primary NK CTLs. were primed IL‐2, IL‐12/IL‐18, or IL‐15, reflecting different physiological therapeutically used activation conditions. expected that Cdc42/Rac by...
