Abstract As the climate worsens and the demand for food grows, so does the interest in nanoagriculture. The interaction between plants and nanomaterials (NMs) has been extensively and intensively examined. However, stopping at the outcome of a phenomenon is often insufficient. Therefore, we introduce three important processes of nanoparticle-plant interactions: translocation, transformation, and plant metabolism. During the migration of nanoparticles, size and surface electrical properties are the main determining factors. Additionally, the interaction of nanoparticles with cell membranes is another key aspect of research. The transformation of nanoparticles in plants is mainly due to redox substances. More >

Abstract The present study demonstrates that monocyte-derived dendritic cells (moDCs) produced in vitro using a GM-CSF and IFN-α differentiation protocol encompass a rare (~5%) subpopulation of cells showing classical dendritic cell morphology and capable of natural internalization of extracellular self-DNA. We established that DEFB, HMGB1, LL-37 and RAGE antigens, which mediate the process of DNA internalization, are expressed on the surface of moDCs similar to plasmacytoid dendritic cells. However, in constrast to the latter subpopulation, these cells do not produce interleukin (IL)-37. Nonetheless, the process of DNA internalization was not in direct relation to the presence… More >

Abstract Interleukin (IL)-15 is a cytokine critical for the homeostasis and the function of NK cells, NK-Tcells, and memory CD8+ T cells. IL-15 signals are delivered through the IL-15Rβ and the commonγ (γ_c) receptorchains. The third receptor chain, IL-15Rα, confers specificity and high affinity for the cytokine. While IL-15 canactivate with high affinity the trimeric receptor expressed by a target cell (cis-presentation), IL-15Rα is alsoknown to trans-present IL-15 with high affinity to target cells expressing the IL-15Rβ/γ_c complex. In order tocompare the IL-15 cis- and trans-presentation processes, and using a T cell line expressing both IL-15Rα/β/γ_c andIL-15Rβ/γ_c, we analyzed cell… More >
