Elevated truncated oxidized phospholipids as a factor exacerbating ALI in the aging lungs.

FASEB J 2018 Dec 6:fj201800981R. Epub 2018 Dec 6.

Department of Anesthesiology, University of Maryland School of Medicine, Baltimore, Maryland, USA.

As mechanisms controlling redox homeostasis become impaired with aging, exaggerated oxidant stress may cause disproportional oxidation of cell membranes and circulating phospholipids (PLs), leading to the formation of truncated oxidized PL products (Tr-OxPLs), which exhibit deleterious effects. This study investigated the role of elevated Tr-OxPLs as a factor exacerbating inflammation and lung barrier dysfunction in an animal model of aging. Mass spectrometry analysis of Tr-OxPL species in young (2-4 mo) and aging (18-24 mo) mice revealed elevated basal levels of several products [1-palmitoyl-2-(5-oxovaleroyl)- sn-glycero-phosphocholine (POVPC), 1-palmitoyl-2-glutaroyl- sn-glycero-phosphocholine, lysophosphocholine, 1-palmitoyl-2-(9-oxo-nonanoyl)- sn-glycero-3-phosphocholine, 1-palmitoyl-2-azelaoyl- sn-glycero-3-phosphocholine, O-1-O-palmitoyl-2-O-(5,8-dioxo-8-hydroxy-6-octenoyl)-l-glycero-3-phosphocholine, and others] in the aged lungs.

Role of Macrophage Dopamine Receptors in Mediating Cytokine Production: Implications for Neuroinflammation in the Context of HIV-Associated Neurocognitive Disorders.

J Neuroimmune Pharmacol 2018 Dec 5. Epub 2018 Dec 5.

Department of Pharmacology and Physiology, Drexel University College of Medicine, Philadelphia, PA, 19102, USA.

Despite the success of combination anti-retroviral therapy (cART), around 50% of HIV-infected individuals still display a variety of neuropathological and neurocognitive sequelae known as NeuroHIV. Current research suggests these effects are mediated by long-term changes in CNS function in response to chronic infection and inflammation, and not solely due to active viral replication. In the post-cART era, drug abuse is a major risk-factor for the development of NeuroHIV, and increases extracellular dopamine in the CNS. Read More

Extracellular vesicles from mature dendritic cells (DC) differentiate monocytes into immature DC.

Life Sci Alliance 2018 Dec 3;1(6):e201800093. Epub 2018 Dec 3.

Department of Dermatology, University Hospital Erlangen, Kussmaul Campus, Erlangen, Germany.

During inflammation, murine and human monocytes can develop into dendritic cells (DC), but this process is not entirely understood. Here, we demonstrate that extracellular vesicles (EV) secreted by mature human DC (maDC) differentiate peripheral monocytes into immature DC, expressing a unique marker pattern, including 6-sulfo LacNAc (slan), Zbtb46, CD64, and CD14. While EV from both maDC and immature DC differentiated monocytes similar to GM-CSF/IL-4 stimulation, only maDC-EV produced precursors, which upon maturation stimulus developed into T-cell-activating and IL-12p70-secreting maDC.

Non-coding Class Switch Recombination-Related Transcription in Human Normal and Pathological Immune Responses.

Front Immunol 2018 21;9:2679. Epub 2018 Nov 21.

Centro de Investigación Sobre Enfermedades Infecciosas, Instituto Nacional de Salud Pública, Cuernavaca, Mexico.

Antibody class switch recombination (CSR) to IgG, IgA, or IgE is a hallmark of adaptive immunity, allowing antibody function diversification beyond IgM. CSR involves a deletion of the IgM/IgD constant region genes placing a new acceptor Constant gene, downstream of the VDJ exon. CSR depends on non-coding (CSRnc) transcription of donor I and acceptor I exons, located 5' upstream of each C coding gene. Read More

Immunization of Experimental Dogs With Salivary Proteins From , Using DNA and Recombinant Canarypox Virus Induces Immune Responses Consistent With Protection Against .

Front Immunol 2018 16;9:2558. Epub 2018 Nov 16.

Fundação Oswaldo Cruz, Instituto Gonçalo Moniz, Salvador, Brazil.

Metacyclic promastigotes are transmitted by sand flies that inject parasites and saliva into the host's skin. Previous studies have demonstrated that DNA plasmids encoding salivary proteins LJM17 and LJL143, when used to immunize dogs, resulted in a systemic and local Th1 cell-mediated immunity that interfered in parasite survival . Here we evaluated the ability of these same salivary antigens to induce anti- immunity and to confer protection by immunizing dogs using a novel vaccination strategy more suitable for use in the field.

Analysis of Lipid Metabolism, Immune Function, and Neurobehavior in Adult C57BL/6JxFVB Mice After Developmental Exposure to di (2-ethylhexyl) Phthalate.

Front Endocrinol (Lausanne) 2018 21;9:684. Epub 2018 Nov 21.

Institute for Risk Assessment Sciences (IRAS), Utrecht University, Utrecht, Netherlands.

Developmental exposure to di (2-ethylhexyl) phthalate (DEHP) has been implicated in the onset of metabolic syndrome later in life. Alterations in neurobehavior and immune functions are also affected by phthalate exposure and may be linked to the metabolic changes caused by developmental exposure to DEHP. Our goal was to study the effects of developmental exposure to DEHP in the context of metabolic syndrome by integrating different parameters to assess metabolic, neurobehavioral, and immune functions in one model.

Divergent Effects of Metformin on an Inflammatory Model of Parkinson's Disease.

Front Cell Neurosci 2018 21;12:440. Epub 2018 Nov 21.

Instituto de Biomedicina de Sevilla (IBiS), Hospital Universitario Virgen del Rocío/CSIC/Universidad de Sevilla, Seville, Spain.

The oral antidiabetic drug metformin is known to exhibit anti-inflammatory properties through activation of AMP kinase, thus protecting various brain tissues as cortical neurons, for example. However, the effect of metformin on the substantia nigra (SN), the main structure affected in Parkinson's disease (PD), has not yet been studied in depth. Inflammation is a key feature of PD and it may play a central role in the neurodegeneration that takes place in this disorder. Read More
