Meditation and Compassion Therapy in Psychiatric Disorders: A Pilot Study.

Introduction Our study aimed to compare meditation and compassion-based group therapy with the standard of care in patients with eating disorders, drug addiction, alcohol addiction, and depression, concerning acceptance, mindfulness awareness, self-compassion, and psychological distress. Methods A controlled designed study was performed, comparing meditation and compassion-focused group therapy added to the standard of care with the standard of care alone, on patients with eating disorders, drug addiction, alcohol addiction, and mood disorders. Four validated questionnaires were administered: the Acceptance and Action Questionnaire-II (AAQ-II), which assesses the ability to be fully in touch with the present moment; the Mindful Attention Awareness Scale (MAAS), which assesses the ability to experience consciously what is happening in the present moment; the Self-Compassion Scale (SCS), which assesses self-compassion characteristics, including loving-kindness; and the Symptom Checklist-90 (SCL-90), which measures psychological distress (anxiety, depression, psychotic behavior, etc.

Extracellular vesicles at the crossroad between cancer progression and immunotherapy: focus on dendritic cells.

Extracellular vesicles (EVs) are nanosized heat-stable vesicles released by virtually all cells in the body, including tumor cells and tumor-infiltrating dendritic cells (DCs). By carrying molecules from originating cells, EVs work as cell-to-cell communicators in both homeostasis and cancer but may also represent valuable therapeutic and diagnostic tools. This review focuses on the role of tumor-derived EVs (TEVs) in the modulation of DC functions and on the therapeutic potential of both tumor- and DC-derived EVs in the context of immunotherapy and DC-based vaccine design.

Inhibitory receptors of plasmacytoid dendritic cells as possible targets for checkpoint blockade in cancer.

Plasmacytoid dendritic cells (pDCs) are the major producers of type I interferons (IFNs), which are essential to mount antiviral and antitumoral immune responses. To avoid exaggerated levels of type I IFNs, which pave the way to immune dysregulation and autoimmunity, pDC activation is strictly regulated by a variety of inhibitory receptors (IRs). In tumors, pDCs display an exhausted phenotype and correlate with an unfavorable prognosis, which largely depends on the accumulation of immunosuppressive cytokines and oncometabolites.

Extracellular microRNAs induce dendritic cell-dependent joint inflammation and potentiate osteoclast differentiation via TLR7/8 engagement.

Objectives: Monocyte-derived dendritic cells (DCs) are key players in the induction of inflammation, autoreactive T cell activation and loss of tolerance in rheumatoid arthritis (RA), but the precise mechanisms underlying their activation remain elusive. Here, we hypothesized that extracellular microRNAs released in RA synovial fluids may represent a novel, physiological stimulus triggering unwanted immune response via TLR8-expressing DC stimulation.

Methods: Human monocyte-derived DCs were stimulated with a mixture of GU-rich miRNAs upregulated in RA tissues and released in synovial fluids (Ex-miRNAs).

Comparing Commercial Metal-Coated AFM Tips and Home-Made Bulk Gold Tips for Tip-Enhanced Raman Spectroscopy of Polymer Functionalized Multiwalled Carbon Nanotubes.

Tip-enhanced Raman spectroscopy (TERS) combines the high specificity and sensitivity of plasmon-enhanced Raman spectroscopy with the high spatial resolution of scanning probe microscopy. TERS has gained a lot of attention from many nanoscience fields, since this technique can provide chemical and structural information of surfaces and interfaces with nanometric spatial resolution. Multiwalled carbon nanotubes (MWCNTs) are very versatile nanostructures that can be dispersed in organic solvents or polymeric matrices, giving rise to new nanocomposite materials, showing improved mechanical, electrical and thermal properties.
