Highly Active Antiretroviral Therapy (HAART) has significantly contributed to the increase of HIV-infected survivors over 50 years of age. Unfortunately, patients are required to stay on long-term HAART, which may be causally related to the development of neurological problems such as chronic pain. Little is known about the contribution of HAART or its therapeutic agents to the pathogenesis of pain during aging. In this study, we determined the effect of nucleoside reverse transcriptase inhibitors (NRTIs) on the development of mechanical allodynia and the potential underlying mechanism in aging mice (15...

Exposure to Δ9-tetrahydrocannabinol (THC) in vitro and in animal models can significantly impair the differentiation, activation and function of dendritic cells, T cells and B cells. However, studies directly assessing the impact of marijuana smoking on human immunity are lacking. A prospective study of immune responses to a standard hepatitis B vaccination was therefore carried out in a matched cohort of 9 marijuana smokers (MS) and 9 nonsmokers (NS). In addition to their regular marijuana use, MS smoked four marijuana cigarettes in a monitored setting on the day of each vaccination...

Cerebrospinal fluid (CSF) drains via the lymphatic drainage pathway. This lymphatic pathway connects the central nervous system (CNS) to the cervical lymph node (CLN). As the CSF drains to CLN via the dural and nasal lymphatics, T cells and antigen presenting cells pass along the channels from the subarachnoid space through the cribriform plate. Human immunodeficiency virus (HIV) may also egress from the CNS along this pathway. As a result, HIV egressing from the CNS may accumulate within the CLN. Towards this objective, we analyzed CLNs isolated from rhesus macaques that were chronically-infected with simian immunodeficiency virus (SIV)...

Microglia and macrophages are the main non-neuronal subsets of myeloid origin in the brain, and are critical regulators in neurodegenerative disorders, where inflammation is a key factor. Since HIV infection results in neurological perturbations that are similar to those in aging, we examined microglial and infiltrating myeloid subsets in the search for changes that might resemble the ones in aging. For that, we used the SIV infection in rhesus macaques to model neuroAIDS. We found that Sirt-1, a molecule that impacts survival and health in many models, was decreased in cell preparations containing a majority of microglia and myeloid cells from the brain of infected macaques...

Microglia are involved in various homeostatic processes in the brain, including phagocytosis, apoptosis, and synaptic pruning. Sex differences in microglia colonization of the developing brain have been reported, but have not been established following alcohol insult. Developmental alcohol exposure represents a neuroimmune challenge that may contribute to cognitive dysfunction prevalent in humans with Fetal Alcohol Spectrum Disorders (FASD) and in rodent models of FASD. Most studies have investigated neuroimmune activation following adult alcohol exposure or following multiple exposures...

High mobility group box 1 (HMGB1), a nuclear protein, once released into the extracellular space under pathological conditions, plays a pronociceptive role in redox-dependent distinct active forms, all-thiol HMGB1 (at-HMGB1) and disulfide HMGB1 (ds-HMGB1), that accelerate nociception through the receptor for advanced glycation endproducts (RAGE) and Toll-like receptor 4 (TLR4), respectively. Thrombomodulin (TM), an endothelial membrane protein, and soluble TM, known as TMα, promote thrombin-mediated activation of protein C and also sequester HMGB1, which might facilitate thrombin degradation of HMGB1...

This study highlights a novel approach to upregulate mitochondrial biogenesis in neuronal cells. RNS60 is a 0.9% saline solution containing oxygenated nanobubbles that is generated by subjecting normal saline to Taylor-Couette-Poiseuille (TCP) flow under elevated oxygen pressure. RNS60, but not NS (normal saline), PNS60 (saline containing a comparable level of oxygen without the TCP modification), or RNS10.3 (TCP-modified normal saline without excess oxygen), increased the expression of Nrf1, Tfam, Mcu, and Tom20 (genes associated with mitochondrial biogenesis) and upregulated mitochondrial biogenesis in MN9D dopaminergic neuronal cells...

Extracellular vesicles (EVs) are physiological vesicles secreted from most eukaryotes and contain cargos of their cell of origin. EVs, and particularly a subset of EV known as exosomes, are emerging as key mediators of cell to cell communication and waste management for cells both during normal organismal function and in disease. In this review, we investigate the rapidly growing field of exosome biology, their biogenesis, cargo loading, and uptake by other cells. We particularly consider the role of exosomes in Alzheimer's disease, both as a pathogenic agent and as a disease biomarker...

Parkinson's disease (PD) is recognized as the most common neurodegenerative movement disorder and results in debilitating motor deficits. The accumulation and spread of neurotoxic synuclein aggregates in the form of Lewy bodies is a key pathological feature of PD. Chronic activation of the NLRP3 inflammasome by protein aggregates is emerging as a major pathogenic mechanism in progressive neurodegenerative disorders and is considered an important therapeutic target. Recently the ketone body, β-hydroxy butyrate (BHB), was shown to efficiently inhibit the NLRP3 inflammasome in macrophages, and in vivo models of inflammatory disease...

Extracellular high mobility group box 1 (HMGB1) activates the receptor for advanced glycation end products (RAGE) or Toll-like receptor 4 (TLR4) and forms a heterocomplex with CXCL12 that strongly activates CXCR4, promoting inflammatory and pain signals. In the present study, we investigated the role of HMGB1 in pancreatic pain accompanying cerulein-induced acute pancreatitis in mice. Abdominal referred hyperalgesia accompanying acute pancreatitis occurred within 1 h after 6 hourly injections of cerulein. The anti-HMGB1 neutralizing antibody or recombinant human soluble thrombomodulin (rhsTM), known to inactivate HMGB1, abolished the cerulein-induced referred hyperalgesia, but not pancreatitis itself...

The application of combination antiretroviral therapy has greatly reduced the death rate from AIDS. However, up to 50% of patients on combination antiretroviral therapy develop HIV-associated neurocognitive disorders (HAND), which is associated with residual neuroinflammation and oxidative injury in the brain. Neural stem cells (NSCs) and progenitors play a vital role in repairing neuronal injuries. Therefore, we hypothesize that combination antiretroviral therapy may adversely affect NSCs/progenitors, contributing to the increasing prevalence of HAND...

It is well established that infection has a significant detrimental effect on patients with Alzheimer's disease (AD), accelerating cognitive decline and, even in healthy ageing individuals, increasing amyloid-β (Aβ) accumulation in the brain. In animal models of AD infection can also cause damage, with evidence of increased neuroinflammation, amyloid pathology and deterioration of cognitive function. These changes are against a backdrop of an age- and AD-related increase in susceptibility to infection. Here we set out to determine whether FTY720, a molecule that binds sphingosine-1-phosphate (S1P) receptors and with known immunosuppressant effects mediating its therapeutic action in multiple sclerosis (MS), might modulate the impact of infection in a mouse model of AD...

Dopamine (DA) is a neurotransmitter in the central nervous system as well as in peripheral tissues. Emerging evidence however points to DA also as a key transmitter between the nervous system and the immune system as well as a mediator produced and released by immune cells themselves. Dopaminergic pathways have received so far extensive attention in the adaptive branch of the immune system, where they play a role in health and disease such as multiple sclerosis, rheumatoid arthritis, cancer, and Parkinson's disease...

Diabetes mellitus (DM) is a disorder due to the inability properly to metabolize glucose associated with dysregulation of metabolic pathways of lipids and proteins resulting in structural and functional changes of various organ systems. DM has detrimental effects on the vasculature, resulting in the development of various cardiovascular diseases and stemming from microvascular injury. The blood brain barrier (BBB) is a highly specialized structure protecting the unique microenvironment of the brain. Endothelial cells, connected by junctional complexes and expressing numerous transporters, constitute the main cell type in the BBB...

Ischemic stroke is a major cause of mortality and disability worldwide. As a part of Traditional Chinese Medicine (TCM), acupuncture has been shown to be effective in promoting recovery after stroke. In this article, we review the clinical and experimental studies that demonstrated the mechanisms of acupuncture treatment for cerebral ischemia. Clinical studies indicated that acupuncture activated relevant brain regions, modulated cerebral blood flow and related molecules in stroke patients. Evidence from laboratory indicated that acupuncture regulates cerebral blood flow and metabolism after the interrupt of blood supply...

HIV infection and aging are each associated with neurocognitive impairment (NCI). This study examined the combined effects of HIV infection and aging on NCI. We performed a cross-sectional survey among 345 HIV-infected and 345 HIV-uninfected participants aged at least 40 years. The International HIV Dementia Scale (IHDS) and Chinese version of Mini-mental State Examination (MMSE) were administered to screen for NCI. HIV-infected individuals had higher prevalence of NCI than uninfected individuals (46.7% vs 15...

A growing body of evidence suggests that excessive microglial activation and pesticide exposure may be linked to the etiology of PD; however, the mechanisms involved remain elusive. Emerging evidence indicates that intracellular inflammasome complex namely NLRP3 complex is involved in the recognition and execution of host inflammatory response. Thus, in the present study, we investigated the hypothesis that NLRP3 inflammasome activation is linked to rotenone (ROT)-induced microglial activation which is dependent upon a priming stimulus by a pathogen-associated molecular pattern (PAMP) or damage associated molecular pattern (DAMP), respectively...

JC virus (JCV) is a human polyomavirus and the etiologic agent of the demyelinating disease progressive multifocal leukoencephalopathy (PML). PML is observed in patients with underlying immunocompromising conditions, suggesting that neuro-immune interactions between peripheral immune cells and neuro-glia play an important role in controlling viral reactivation in the brain. There is little known about the immunobiology of JCV reactivation in glial cells and the role of immune, glial, and viral players in this regulation...
