Exploring the changes of brain immune microenvironment in Alzheimer's disease based on PANDA algorithm combined with blood brain barrier injury-related genes.

Biochem Biophys Res Commun 2021 Apr 14;557:159-165. Epub 2021 Apr 14.

College of Information Engineering, Shanghai Maritime University, 1550 Haigang Ave., Shanghai, 201306, PR China. Electronic address:

Studies have shown that the specific entry of peripheral cells into the brain parenchyma caused by BBB injury and the imbalance of the immune microenvironment in the brain are closely related to the pathogenesis of Alzheimer's disease (AD). Because of the difficulty of obtaining data inside the brain, it is urgent to find out the relationship between the peripheral and intracerebral data and their influence on the development of AD by machine learning methods. However, in the actual algorithm design, it is still a challenge to extract relevant information from a variety of data to establish a complete and accurate regulatory network. Read More

Cell Immunol 2021 Apr 8;364:104359. Epub 2021 Apr 8.

DST-NRF Centre of Excellence for Biomedical Tuberculosis Research, South African Medical Research Council Centre for Tuberculosis Research, Division of Molecular Biology and Human Genetics, Faculty of Medical and Health Sciences, Stellenbosch University, Cape Town, South Africa. Electronic address:

Conventional anti-tuberculosis (TB) therapies comprise lengthy antibiotic treatment regimens, exacerbated by multi-drug resistant and extensively drug resistant mycobacterial strains. We assessed the ability of all-trans retinoic acid (ATRA), as repurposed compound serving as host-directed therapy (HDT), to counteract the suppressive effects of myeloid-derived suppressor cells (MDSCs) obtained from active TB cases (untreated or during week one of treatment) on T-cell responsiveness. We show for the first time that MDSCs suppress non-specific T-cell activation and production of interleukin (IL)-2, IL-4, IL-13 and GM-CSF via contact-dependent mechanisms. Read More

Green toxicology approach involving polylactic acid biomicroplastics and neotropical tadpoles: (Eco)toxicological safety or environmental hazard?

Sci Total Environ 2021 Apr 9;783:146994. Epub 2021 Apr 9.

Post-Graduate Program in Conservation of Cerrado Natural Resources, Goiano Federal Institute, Urutaí, GO, Brazil; Post-Graduate Program in Biodiversity and Biotechnology, Federal University of Goiás, Goiânia, Brazil.

Different and alternative renewable-source materials, commonly called bioplastics, have been proposed due to the high production and consumption of petroleum-derived plastics and to their high toxicity in the biota. However, their toxicological safety has not yet been assessed in a comprehensive way; therefore, their effects on several animal groups remain completely unknown. Thus, we aimed at testing the following hypothesis: the exposure of Physalaemus cuvieri tadpoles to polylaic acid biomicroplastic (PLA BioMP) at environmentally relevant concentrations (760 and 15,020 μg/L) induces physiological changes in them.

Climate-driven fluxes of organic-bound uranium to an alpine lake over the Holocene.

Sci Total Environ 2021 Apr 1;783:146878. Epub 2021 Apr 1.

Institut de Minéralogie, de Physique des Matériaux et de Cosmochimie (IMPMC), UMR 7590, Sorbonne Université-CNRS-MNHN-IRD, Paris, France.

Uranium (U) isotopic signatures and concentration in sediments are widely used as paleo-redox proxies, as the behavior of U is often controlled by bottom water oxygenation. Here, we investigated the processes controlling U accumulation in the sediments of Lake Nègre (Mediterranean Alps, South-East France) over the past 9200 years. Exceptionally high natural U concentrations (350-1250 μg·g) allowed the measurement of U along with other elements by high-resolution X-Ray Fluorescence core-scanning. Read More
