Chronic and debilitating neurodegenerative diseases, such as Parkinson's disease (PD), impose an immense medical, emotional, and economic burden on patients and society. Due to a complex interaction between genetic and environmental risk factors, the etiology of PD remains elusive. However, the cumulative evidence emerging from clinical and experimental research over the last several decades has identified mitochondrial dysfunction, oxidative stress, neuroinflammation, and dysregulated protein degradation as the main drivers of PD neurodegeneration...

Microglial cells are brain specific professional phagocytic immune cells that play a crucial role in the inflammation- mediated neurodegeneration especially in Parkinson's disease (PD) and Alzheimer's disease. Glia maturation factor (GMF) is a neuroinflammatory protein abundantly expressed in the brain. We have previously shown that GMF expression is significantly upregulated in the substantia nigra (SN) of PD brains. However, its possible role in PD progression is still not fully understood. The Clustered-Regularly Interspaced Short Palindromic Repeats (CRISPR)-CRISPR Associated (Cas) protein9 (CRISPR/Cas9) system is a simple, rapid and often extremely efficient gene editing tool at desired loci, enabling complete gene knockout or homology directed repair...

Georges J M Maestroni
Hematopoiesis produce every day billions of blood cells and takes place in the bone marrow (BM) by the proliferation and differentiation of hematopoietic stem cells (HSC). HSC are found mainly adjacent to the BM vascular sinusoids where endothelial cells and mesenchimal stromal cells promote HSC maintenance by producing a variety of factors. Other cell types that regulate HSC niches include sympathetic nerves, non-myelinating Schwann cells and a variety of mature hematopoietic cells such as macrophages, neutrophils, and megakaryocytes...

Bruton's tyrosine kinase (BTK), a critical component of B cell receptor signaling, has recently been implicated in regulation of the peripheral innate immune response. However, the role of BTK in microglia, the resident innate immune cells of the central nervous system, and its involvement in the pathobiology of neurodegenerative disease has not been explored. Here we found that BTK is a key regulator of microglial phagocytosis. Using potent BTK inhibitors and small interfering RNA (siRNA) against BTK, we observed that blockade of BTK activity decreased activation of phospholipase gamma 2, a recently identified genetic risk factor in Alzheimer's disease (AD), and reduced phagocytosis in rodent microglia and human monocyte-derived macrophages...

Neuropathy, typically diagnosed by the presence of either symptoms or signs of peripheral nerve dysfunction, remains a frequently reported complication in the antiretroviral (ART)-treated HIV population. This study was conducted in 109 healthy controls and 57 HIV-infected individuals to investigate CNS regions associated with neuropathy. An index of objective neuropathy was computed based on 4 measures: deep tendon ankle reflex, vibration sense (great toes), position sense (great toes), and 2-point discrimination (feet)...

Macrophages as reservoirs for persistent HIV infection has gained renewed importance, with an intense research focus dedicated to eradication strategies. Clearance of both latent and productive HIV from these important reservoirs is essential for successful eradication. This spe cial theme issue contains 11 papers, including 6 Invited Reviews, 1 Brief Report and 4 Original Articles, that focus on the various aspects of the macrophage as pertains to HIV persistence, latency and cure. These topics include: functional latency of macrophages and microglia, the link between peripheral monocytes and pathogenesis, macrophages as sources of HIV RNA and DNA in virally suppressed patients, brain imaging of neuroinflammation, macrophages as drug delivery vehicles, therapeutic strategies of infected macrophages for cure, and the role of drugs of abuse in enhancing macrophage viral persistence...

Adult-onset neurodegenerative disorders, like Parkinson's disease (PD) and dementia with Lewy bodies (DLB), that share the accumulation of aggregated α-synuclein (αSynagg ) as their hallmark molecular pathology are collectively known as α-synucleinopathies. Diagnosing α-synucleinopathies requires the post-mortem detection of αSynagg in various brain regions. Recent efforts to measure αSynagg in living patients include quantifying αSynagg in different biofluids as a biomarker for PD. We adopted the real-time quaking-induced conversion (RT-QuIC) assay to detect very low levels of αSynagg ...

REVIEW
Pia M Vidal, Rodrigo Pacheco
Dopamine has emerged as a fundamental regulator of inflammation. In this regard, it has been shown that dopaminergic signalling pathways are key players promoting homeostasis between the central nervous system and the immune system. Dysregulation in the dopaminergic system affects both innate and adaptive immunity, contributing to the development of numerous autoimmune and inflammatory pathologies. This makes dopamine receptors interesting therapeutic targets for either the development of new treatments or repurposing of already available pharmacological drugs...

The neurotoxicity of Aβ peptides has been well documented, but effective neuroprotective approaches against Aβ neurotoxicity are unavailable. In the present study, we investigated effects of 1-Methylnicotinamide (MNA), known as a main metabolite of nicotinamide (NA), on the impairment of learning and memory induced by Aβ and the underlying mechanisms. We found that intragastric administration of MNA at 100 or 200 mg/kg for 3 weeks significantly reversed bilateral intrahippocampal injection of Aβ1-42 -induced cognitive impairments in the Morris water maze (MWM), Y-maze and Novel object recognition tests...

Evidence supporting the use of β2AR agonists in synucleinopathies is rapidly growing. Findings come from different scientific approaches. Molecular and immunological data suggest that adrenergic stimulation may decrease both α-synuclein (α-syn) deposition and pro-inflammatory/neurotoxic molecules release. Small open label clinical trials including a total number of 25 Parkinson's disease (PD) patients, in which the β2AR agonist salbutamol was added to levodopa, suggest a promising symptomatic benefit. In line with these findings, epidemiological studies investigating the risk of PD development suggest that long term exposure to the agonist salbutamol might be protective, while the antagonist propranolol possibly detrimental...

Mixed lineage kinases (MLKs) are a group of serine-threonine kinases that evolved in part to respond to endogenous and exogenous insults that result in oxidative stress and pro-inflammatory responses from innate immune cells. Human immunodeficiency virus type 1 (HIV-1) thrives in these conditions and is associated with the development of associated neurocognitive disorders (HAND). As part of a drug discovery program to identify new therapeutic strategies for HAND, we created a library of broad spectrum MLK inhibitors with drug-like properties...

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...

The development of combined antiretroviral therapy (cART) has increased the lifespan of persons living with HIV (PLWH), with most PLWH having a normal life expectancy. While significant progress has occurred, PLWH continue to have multiple health complications, including HIV associated neurocognitive disorders (HAND). While the exact cause of HAND is not known, persistent neuroinflammation is hypothesized to be an important potential contributor. Molecular imaging using positron emission tomography (PET) can non-invasively evaluate neuroinflammation...

Humanized mice have become useful animal models for HIV/AIDS. Since NOD.Cg-Prkdc scid Il2rgtm1Wjl/SzJ (NSG) mice allow the engraftment of primary human immune cells, we aim to determine the role of human Fms-related tyrosine kinase 3 ligand (hFlt3L), a major growth factor for dendritic cells (DCs), in regulating the differentiation of cord blood-derived CD34+ progenitor cells in this murine species. Soluble recombinant hFlt3L protein and AAV-vectored hFlt3L were administrated before or after human CD34+ progenitor cell transplantation, respectively...
