Another potential application of the contact lenses are smart lenses applied in the biosensing and diagnosis of various ocular disorders. The review summarizes and discusses the widespread therapeutic applications of next-generation contact lenses and various fabrication approaches, including its clinical implications, efforts taken by researchers in exploring the novel materials and diverse forms of the lenses, mechanisms of drug release, clinical trials, and their toxicity and safety concerns.Depression is a common mental disorder, and its main environmental risk factor is chronic stress. The activation of mammalian STE20-like kinase 1 (MST1), a key factor involved in the underlying pathophysiology of stress, can trigger synaptic plasticity impairment, neuronal dysfunction and neuroinflammation. However, it is unclear whether down-regulation of MST1 in the hippocampus protects against stress-induced behavioural dysfunctions. Azaindole 1 nmr In this study, three mouse models were used to assess the role of MST1 in stress. Various behavioural tests, in vivo electrophysiological recordings, Western blotting, Golgi staining and immunofluorescence assay were used. The data showed that the level of phospho-MST1 (T183) was significantly increased in the hippocampus of mice subjected to chronic unpredictable mild stress (CUMS) and that mice with MST1 overexpression showed depression-like behaviours. Importantly, the impairment of cognitive functions and the hippocampal synaptic plasticity induced by CUMS were significantly improved by MST1 knockdown, suggesting that MST1 down-regulation effectively protected against stress-induced behavioural dysfunctions. Moreover, MST1 knockdown suppressed CUMS-induced microglial activation, reduced the abnormal expression of inflammatory cytokines and impeded the activation of p38, implying that the antidepressant-like effects of MST1 knockdown were associated with inhibiting the p38 pathway. These findings suggest that hippocampal MST1 is an essential regulator of stress, which can be an ideal target for the development of antidepressants in the future.Depression is a serious disease that has considerable impact on lipid metabolism and inflammatory responses. Recent studies have shown that leptin, which is well known as a mediator of energy homeostasis and is a cytokine in inflammatory response, plays an important role in depression. Acupuncture is widely used to treat depression; however, the underlying mechanisms and the effect of acupuncture on depression remain poorly understood. In this study, we utilized the chronic restraint stress (CRS) induced depression model and acupuncture treatment was performed at KI10, LR8, LU8, LR4 (AP) or non-acupoint (NP). Then, lipidomics was applied to investigate the effects of acupuncture on lipid metabolism and analyze leptin signals in the brain and changes of immune markers. Acupuncture treatment at AP improved depression-like behavior in an open-field test, forced swimming test, and marble burying test. Concurrently, CRS mice treated with AP acupuncture (CRS + AP) had significantly lower levels of aspartate aminotrectively alleviated the depression-like behavior, affected immune responses, and altered hepatic lipid metabolism through the attenuation of leptin insensitivity.A growing body of studies indicated that exosomes are one of vital players in pathological process of neuropsychiatric diseases, but their role in major depressive disorder (MDD) remains poorly understood. Here we purified plasma exosomes from depression including lipopolysaccharide (LPS)-challenged depression, chronic restraint stress (CRS)-induced depression, MDD subjects, and from control mice or volunteers. The therapeutic effect of these exogenous exosomes was assessed utilizing behavioral tests and biochemical approaches in the LPS-caused depression or microglial BV2 cells. The expression of exosomal sigma-1 receptor (Sig-1R) was evaluated by western blotting. The role of Sig-1R in the biological function of exosomes was determined using Sig-1R knockout mice and HEK 293 cells. Our results revealed that injection of exosomes from depression models or patients rather than normal controls significantly ameliorated depressive-like behaviors, deficiency of BDNF expression and neuro-inflammation in LPS-challenged mice. In addition, co-culture with exosomes from depression models or patients instead of from controls prevented LPS-induced inflammation responses in microglial BV2 cells. Moreover, Sig-1R was demonstrated for the first time to significantly be enriched in exosomes from depression models or patients compared with that from normal controls. However, Sig-1R null exosomes no longer emerged antidepressant-like action in LPS-challenged mice. Thus, we demonstrated that plasma exosomes from depression exerted antidepressant-like effects in a Sig-1R dependent manner in the LPS-induced depression. This work improves our understanding of the exosomes in depression, suggesting a novel exosomes-based approach for MDD treatment.
Neuropsychiatric lupus (NPSLE), a manifestation of the autoimmune disease systemic lupus erythematosus (SLE), is characterized by psychiatric symptoms including anxiety and depression and upregulated autoantibodies. The B6.Nba2 spontaneous mouse model develops SLE, but has not previously been tested for NPSLE.

We investigated the NPSLE phenotype in male and female B6.Nba2 mice (n=12 each) and age- and sex-matched B6 controls (n=10 each) via behavioral assessments for anxiety, depression, and memory deficits. Serum anti-dsDNA, anti-nRNP, anti-DWEYS peptide reactive IgG autoantibody levels and soluble TWEAK levels were determined by ELISA. Hippocampal regions were stained for activated microglia and neurons.

Both male and female B6.Nba2 mice showed elevated anti-dsDNA IgG, anti-nRNP IgG and anti-DWEYS reactive antibodies, elevated serum soluble TWEAK levels, and a strong anxiety and depression phenotype (p<0.05-0.0001). Male B6.Nba2 mice developed this phenotype at a slightly older age than females. Female B6.Nba2 mice displayed reduced numbers of neurons in the hippocampal region compared to female B6 controls (p<0.05).

The B6.Nba2 mouse model recapitulates many known NPSLE phenotypes, making it a promising model to investigate the development of NPSLE in the context of SLE.

Anti-inflammatory miRNAs are elevated in sEVs secreted by RAW 264.7 mouse macrophages after lipopolysaccharide (LPS) stimulation. We observed uptake of these sEVs by primary mouse cortical neurons, microglia and astrocytes followed by downregulation of proinflammatory miRNA target genes in recipient cells. Pre-treating primary microglia with these sEVs decreased pro-inflammatory gene expression. A single intrathecal injection of sEVs derived from LPS stimulated RAW 264.7 cells attenuated mechanical hyperalgesia in the complete Freund's adjuvant (CFA) mouse model of inflammatory pain and formalin induced acute pain. Importantly, sEVs did not alter the normal pain threshold in control mice. RNA sequencing of dorsal horn of the spinal cord showed sEVs-induced modulation of immune regulatory pathways. Further, a single prophylactic intrathecal injection of sEVs two weeks prior, attenuated CFA-induced pain hypersensitivity and was ineffective in formalin model. This indicates that prophylactic sEVs administration can be beneficial in attenuating chronic pain without impacting responses to the protective physiological and acute inflammatory pain. Prophylactic administration of sEVs could form the basis for a safe and novel vaccine-like therapy for chronic pain or as an adjuvant, potentially reducing the dose of drugs needed for pain relief.Accumulating evidence indicates the specific involvement of inflammatory processes in major depressive disorder (MDD), particularly affecting innate immunity. Most immune alterations have so far been determined based on plasma or cerebrospinal fluid cytokine levels. To precisely characterize putative innate immune-mediated mechanisms in MDD pathogenesis, we sought to disentangle "state" from "trait" effects in a patient-specific cell model by quantifying the impact of patient-derived autologous sera (AS) on patient-specific monocyte-derived macrophages (Mo-MФs) polarization in vitro. Mo-MФs were generated from 28 patients with moderate to severe MDD and 28 age-, sex-, smoking status- and BMI-matched healthy controls (HC). Cells were treated either with AS or fetal calf serum (FCS) and polarized into M1 (LPS), M2 (IL-10, IL-4, TGF-β) or M0 (unstimulated) macrophages. Polarization capacity was quantified by means of specific M1 (CCR7, CD86, CXCL10, IL-12p70, TNF-α, IL-6, IL-1β, IL-12p40, IL-23, IP-10) and M2 (CD206, IL-10, TARC, IL-1RA) markers. Compared to HC, significantly increased M1-polarization was observed for MDD patients in the presence of FCS, however, polarization in AS enriched media determined an increased M2-polarization in patients. Moreover, female MDD patients exhibited increased M1- and decreased M2-polarization in both conditions compared to male MDD patients. Our data suggests that Mo-MФs derived from patients with MDD exhibit facilitated M1-polarization under traditional cell culture conditions and an increased potential for M2-polarization when cultured in AS. Striking inter-individual variation and pronounced gender effects highlight the potential utility of our personalized cell model-based approach to aid diagnostic and therapeutic decisions.Monoclonal antibodies targeting tumors are one of the most important discoveries in the field of cancer. Although several effective antibodies have been developed, a relapse may occur. One of their mechanisms of action is Antibody Dependent Cell Cytotoxicity (ADCC), by engaging the Fc γ receptor CD16 expressing Natural Killer cells, innate lymphoid cells involved in cancer immunosurveillance and able to kill tumor cells. A lack of NK cells observed in many cancers may therefore be a cause of the low efficacy of antibodies observed in some clinical situations. Here we review clear evidences of the essential partnership between NK cells and antibodies showed in vitro, in vivo, and in clinical trials in different indications, describe the hurdles and ways to enhance ADCC and the evolution of monoclonal antibody therapy. NK cell adoptive immunotherapy combined with monoclonal antibodies may overcome the resistance to the treatment and enhance their efficacy.Emotion plays an important role in people's lives. However, the neural mechanism of affective perception is still unclear. In this study, steady-state visual evoked potentials (SSVEPs) were used to explore information processing speed and interactions among cortical structures involved in affective perception. Pleasant, unpleasant, and neutral pictures selected from the International Affective Picture System were presented either in intact or phase-scrambled form at a fixed frequency, where the induced SSVEPs could be used as a frequency marker of brain activity with high temporal resolution and signal-to-noise ratio. Source estimation methods were used to reconstruct the cortical signals. The information processing of affective images was studied by phase and causal connection analysis in the cortical space to investigate the information processing speed of the local brain region and the dynamic interactions across brain regions. Experimental results showed that affective and semantic perception was accompanied by the acceleration of information processing speed in the ventral pathway.
