An alkyne-functionalized ruthenium(II) bis-terpyridine complex is directly copolymerized with phenylacetylene by alkyne polymerization. The polymer is characterized by size-exclusion chromatography (SEC), (1) H NMR spectroscopy, cyclic voltammetry (CV) measurements, and thermal analysis. The photophysical properties of the polymer are studied by UV-vis absorption spectroscopy. In addition, spectro-electrochemical measurements are carried out. Time-resolved luminescence lifetime decay curves show an enhanced lifetime of the metal complex attached to the conjugated polymer backbone compared with the Ru(tpy)2 (2+) model complex.

The CD2-depleting drug alefacept (LFA3-Ig) preserved beta cell function in new-onset type 1 diabetes (T1D) patients. The most promising biomarkers of response were late expansion of exhausted CD8 T cells and rare baseline inflammatory islet-reactive CD4 T cells, neither of which can be used to measure responses to drug in the weeks after treatment. Thus, we investigated whether early changes in T cell immunophenotypes could serve as biomarkers of drug activity.

While several African swine fever virus (ASFV)-encoded proteins potently interfere with the cGAS-STING (cyclic GMP-AMP synthetase-stimulator of interferon genes) pathway at different levels to suppress interferon (IFN) type I production in infected macrophages, systemic IFN-α is induced during the early stages of AFSV infection in pigs. The present study elucidates a mechanism by which such responses can be triggered, at least in vitro. We demonstrate that infection of monocyte-derived macrophages (MDMs) by ASFV genotype 2 strains is highly efficient but immunologically silent with respect to IFN type I, IFN-stimulated gene induction, and tumor necrosis factor production.

Diabetic nephropathy is a severe chronic complication characterized by cytotoxicity, inflammation, and fibrosis, ultimately leading to renal failure. This study systematically investigated the effects of the PARP1 inhibitor PJ-34 on high glucose-induced cytotoxicity, inflammation, and fibrosis in HK-2 cells, as well as its improvement on neuropathic pain response and transforming growth factor β (TGFβ) expression in a type 1 diabetes mellitus diabetic nephropathy mouse model. Through cellular and animal experiments, we observed that PJ-34 significantly enhanced the proliferative capacity of cells damaged by high glucose, reduced apoptosis, and decreased the release of proinflammatory factors TGFα, interleukin-6, and interleukin-1β.

A fundamental dichotomy in lymphocytes separates adaptive T and B lymphocytes, with clonally expressed antigen receptors, from innate lymphocytes, which carry out more rapid responses. Some T cell populations, however, are intermediates between these 2 poles, with the capacity to respond rapidly through T cell receptor activation or by cytokine stimulation. Here, using publicly available datasets, we constructed linear mixed models that not only define a gradient of innate gene expression in common for mouse innate-like T cells, but also are applicable to other mouse T lymphoid populations.

Persistent systemic inflammation is associated with an elevated risk of cardiometabolic diseases. However, the characteristics of the innate and adaptive immune systems in individuals who develop these conditions remain poorly defined. Doublets, or cell-cell complexes, are routinely eliminated from flow cytometric and other immune phenotyping analyses, which limits our understanding of their relationship to disease states.
