AGK2 Alleviates Lipopolysaccharide Induced Neuroinflammation through Regulation of Mitogen-Activated Protein Kinase Phosphatase-1
AbstractNeuroinflammation is associated with the progression of multiple neurological diseases. Many studies show that SIRT2 involves in multiple inflammatory processes. While, the mechanisms remain unclear. The purpose of this study was to explore the effect of SIRT2 inhibitor AGK2 on inflammatory responses and MAPK signaling pathways in LPS activated microglia in vitro and in vivo. The effect of AGK2 on cell viability of BV2 microglial cells was detected by CCK-8 assay. The expression of inflammatory cytokine iNOS was analyzed by western blotting and immunofluorescence. The mRNA expressions of iNOS, TNF- α, and IL-1β w...

A Broad Application of CRISPR Cas9 in Infectious, Inflammatory and Neurodegenerative Diseases
AbstractBeing the most important immune-responsive cell type of the CNS, microglia always glorify the so-called crossroad of Neurology, Immunology and Pharmacology. As microglial activation is a hallmark of different neurodegenerative disorders including Alzheimer ’s disease (AD), Parkinson’s disease (PD), HIV-associated neurocognitive disorders (HAND), Amyotrophic lateral sclerosis (ALS), etc., selective targeting of microglial cell signaling may be a valid option to control these neurodegenerative disorders with lesser side effects. This is particularly important as no effective therapies are available against these ...

Protease Inhibitors, Saquinavir and Darunavir, Inhibit Oligodendrocyte Maturation: Implications for Lysosomal Stress
AbstractDespite the introduction of antiretroviral (ARV) therapy (ART), approximately 30 –50% of people living with human immunodeficiency virus-1 (HIV-1) will develop a spectrum of measurable neurocognitive dysfunction, collectively called HIV-associated neurocognitive disorder (HAND). While the clinical manifestations of HAND have changed with the advent of ART, certain pathological features have endured, including white matter alterations and dysfunction. The persistence of white matter alterations in the post-ART era suggests that ARV drugs themselves may contribute to HAND pathology. Our group has previously demonst...

Hemorrhage Associated Mechanisms of Neuroinflammation in Experimental Traumatic Brain Injury
AbstractTraumatic brain injury (TBI) is a major health problem for over 3.17 million people in the US, attracting increasing public attentions. Understanding the underlying mechanism of TBI is urgent for better diagnosis and treatment. Here, we examined the hypothesis that cerebral hemorrhagic coagulation and subsequent immune cells infiltration causes the progressive mechanisms of brain injury in moderate fluid percussion injury model. This represents a subdural hematoma and hemorrhagic head injury. We found increased hemorrhagic lesions and infarct volume in the injured brain with increment of pressure. The extent of hem...

Macrophage-Derived Extracellular Vesicles as Drug Delivery Systems for Triple Negative Breast Cancer (TNBC) Therapy
AbstractEfficient targeted delivery of anticancer agents to TNBC cells remains one of the greatest challenges to developing therapies. The lack of tumor-specific markers, aggressive nature of the tumor, and unique propensity to recur and metastasize make TNBC tumors more difficult to treat than other subtypes. We propose to exploit natural ability of macrophages to target cancer cells by means of extracellular vesicles (EVs) as drug delivery vehicles for chemotherapeutic agents, paclitaxel (PTX) and doxorubicin (Dox). We demonstrated earlier that macrophage-derived EVs loaded with PTX (EV-PTX) and Dox (EV-Dox) target cance...

Beta1- and Beta2-Adrenoceptors Expression Patterns in Human Non-small Cell Lung Cancer: Relationship with Cancer Histology
AbstractAssessment of Beta-AR protein expression on tumour tissues might be a plausible strategy to select cancer patients who can benefit from Beta-blockers therapy. The aim of this study is to evaluate the differences between resected tissue specimens from primary lung cancer (adenocarcinoma (ADC) and squamous cell carcinoma (SCC)) in terms of expression pattern of Beta1- and Beta2-AR in both tumour and adjacent surrounding non-tumour tissue. This retrospective study was based on the analysis of 80 patients with histologically confirmed diagnosis of primary Non-Small Cell Lung Cancer (NSCLC) who received surgical treatme...

Changes of Serum IgG Dimer Levels after Treatment with IVIg in Guillain-Barr é Syndrome
AbstractIntravenous immunoglobulins (IVIg) are standard treatment for Guillain-Barr é syndrome (GBS). Their exact mechanisms of action are versatile and not fully understood. One possible mechanism is neutralization of circulating autoantibodies via binding to anti- idiotypic antibodies forming idiotype-anti-idiotype dimeric IgG immune complexes. To examine the role of immune comp lex formation as mechanism of action for IVIg in GBS, 34 C57Bl/6 mice were either treated with anti-ganglioside antibodies and IVIg or IVIg and PBS alone, whereas eight additional mice were treated either with anti-ganglioside autoantibodies and...

Modern Techniques for the Isolation of Extracellular Vesicles and Viruses
AbstractExtracellular signaling is pivotal to maintain organismal homeostasis. A quickly emerging field of interest within extracellular signaling is the study of extracellular vesicles (EV), which act as messaging vehicles for nucleic acids, proteins, metabolites, lipids, etc. from donor cells to recipient cells. This transfer of biologically active material within a vesicular body is similar to the infection of a cell through a virus particle, which transfers genetic material from one cell to another to preserve an infection state, and viruses are known to modulate EV. Although considerable heterogeneity exists within EV...

Evaluating Neurodevelopmental Consequences of Perinatal Exposure to Antiretroviral Drugs: Current Challenges and New Approaches
AbstractAs antiretroviral therapy (ART) becomes increasingly affordable and accessible to women of childbearing age across the globe, the number of children who are exposed to Human Immunodeficiency Viruses (HIV) but remain  uninfected is on the rise, almost all of whom were also exposed to ART perinatally. Although ART has successfully aided in the decline of mother-to-child-transmission of HIV, the long-term effects of in utero exposure to ART on fetal and postnatal neurodevelopment remain unclear. Evaluating the sa fety and efficacy of therapeutic drugs for pregnant women is a challenge due to the historic limitations ...

A Broad Application of CRISPR Cas9 in Infectious Diseases of Central Nervous System
AbstractVirus-induced diseases or neurological complications are huge socio-economic burden to human health globally. The complexity of viral-mediated CNS pathology is exacerbated by reemergence of new pathogenic neurotropic viruses of high public relevance. Although the central nervous system is considered as an immune privileged organ and is mainly protected by barrier system, there are a vast majority of neurotropic viruses capable of gaining access and cause diseases. Despite continued growth of the patient population and a number of treatment strategies, there is no successful viral specific therapy available for vira...

The Role of β-Blockers in Melanoma
AbstractMelanoma is one of the most aggressive and less chemotherapy-responsive human cancers, representing a major public health issue worldwide. The early diagnosis still represents the best approach in order to reduce mortality, especially in advanced stages. Preclinical evidence, collected through several in vitro and in vivo models, has been accumulating about the pathophysiological involvement of β-adrenoceptors in melanoma progression. This involvement has been paralleled by the evidence that drugs blocking β-adrenoceptors (β-blockers) may have a relevant role in the treatment of melanoma and in the prevention of...

Strategies for the use of Extracellular Vesicles for the Delivery of Therapeutics
AbstractExtracellular vesicles (EVs) are nanosized, membrane-bound vesicles released from eukaryotic and prokaryotic cells that can transport cargo containing DNA, RNA, lipids and proteins, between cells as a means of intercellular communication. Although EVs were initially considered to be cellular debris deprived of any essential biological functions, emerging literature highlights the critical roles of EVs in the context of intercellular signaling, maintenance of tissue homeostasis, modulation of immune responses, inflammation, cancer progression, angiogenesis, and coagulation under both physiological and pathological s...

Host-Immune Interactions in JC Virus Reactivation and Development of Progressive Multifocal Leukoencephalopathy (PML)
AbstractWith the advent of immunomodulatory therapies and the HIV epidemic, the impact of JC Virus (JCV) on the public health system has grown significantly due to the increased incidence of Progressive Multifocal Leukoencephalopathy (PML). Currently, there are no pharmaceutical agents targeting JCV infection for the treatment and the prevention of viral reactivation leading to the development of PML. As JCV primarily reactivates in immunocompromised patients, it is proposed that the immune system (mainly the cellular-immunity component) plays a key role in the regulation of JCV to prevent productive infection and PML deve...
