The ability to isolate specific brain regions of interest can be impeded in tissue disassociation techniques that do not preserve their spatial distribution. Such techniques also potentially skew gene expression analysis because the process itself can alter expression patterns in individual cells. Here we describe a laser capture microdissection (LCM) method to selectively collect specific brain regions affected by traumatic brain injury (TBI) by using a modified Nissl (cresyl violet) staining protocol and the guidance of a rat brain atlas...

BACKGROUND/AIM: To isobolographically determine the types of interactions that occur between retigabine and lacosamide (LCM; two third-generation antiepileptic drugs) with respect to their anticonvulsant activity and acute adverse effects (sedation) in the maximal electroshock-induced seizures (MES) and chimney test (motor performance) in adult male Swiss mice. METHODS: Type I isobolographic analysis for nonparallel dose-response effects for the combination of retigabine with LCM (at the fixed-ratio of 1:1) in both the MES and chimney test in mice was performed...

A common method for cell-associated virus isolation involves disruption of infected cells by a combination of hypotonic burst, freeze-thaw cycles (F-T) and sonication. This protocol was also originally used for the preparation of cell-free extract containing the MX strain of lymphocytic choriomeningitis virus (LCMV), which is preferentially propagated by cell-to-cell contact and does not release distinct virions into the medium. In the present study, we compared different approaches to virus isolation. Based on virus yield, we show that deionized water lysis is the fastest and most effective method for releasing LCMV MX infectious viral particles from persistently infected cells...

Cytotoxic T lymphocytes (CTLs) play a key role in the control of lymphocytic choriomeningitis virus (LCMV) infection. In C57BL/6 mice (H-2(b) ), the CTL response is mainly directed against epitopes from the LCMV glycoprotein (GP) and the nucleoprotein (NP) which represent the two major viral proteins. The role of GP- versus NP-derived epitopes for viral clearance was examined using transgenic (tg) mice ubiquitously expressing LCMV GP and NP, respectively. These mice lack GP- or NP-specific CTLs and show decreased levels of GP- or NP-specific antibodies as a result of tolerance induction...

OBJECTIVE: Many children diagnosed with attention-deficit/hyperactivity disorder (ADHD) experience co-occurring neurodevelopmental and psychiatric disorders, and those who do often exhibit higher levels of impairment than children with ADHD alone. This study provides a latent class analysis (LCA) approach to categorizing children with ADHD into comorbidity groups, evaluating condition expression and treatment patterns in each group. METHODS: Parent-reported data from a large probability-based national sample of children diagnosed with ADHD (2014 National Survey of the Diagnosis and Treatment of ADHD and Tourette Syndrome) were used for an LCA to identify groups of children with similar groupings of neurodevelopmental and psychiatric comorbidities among children with current ADHD (n = 2495)...

Lipid metabolism is increasingly being appreciated to affect immunoregulation, inflammation and pathology. In this study we found that mice infected with lymphocytic choriomeningitis virus (LCMV) exhibit global perturbations of circulating serum lipids. Mice lacking the lipid-sensing surface receptor triggering receptor expressed on myeloid cells 2 (Trem2 (-/-)) were protected from LCMV-induced hepatitis and showed improved virus control despite comparable virus-specific T cell responses. Non-hematopoietic expression of TREM2 was found to be responsible for aggravated hepatitis, indicating a novel role for TREM2 in the non-myeloid compartment...

Hippocampal CA1 pyramidal neurons, a major component of the medial temporal lobe memory circuit, are selectively vulnerable during the progression of Alzheimer's disease (AD). The cellular mechanism(s) underlying degeneration of these neurons and the relationship to cognitive performance remains largely undefined. Here, we profiled neurotrophin and neurotrophin receptor gene expression within microdissected CA1 neurons along with regional hippocampal dissections from subjects who died with a clinical diagnosis of no cognitive impairment (NCI), mild cognitive impairment (MCI), or AD using laser capture microdissection (LCM), custom-designed microarray analysis, and qPCR of CA1 subregional dissections...

Effective CD8(+) T cell responses play an important role in determining the course of a viral infection. Overwhelming antigen exposure can result in suboptimal CD8(+) T cell responses, leading to chronic infection. This altered CD8(+) T cell differentiation state, termed exhaustion, is characterized by reduced effector function, upregulation of inhibitory receptors and altered expression of transcription factors. Prevention of overwhelming antigen exposure which limits CD8(+) T cell exhaustion is of significant interest for controlling chronic infection...

Hemophagocytic lymphohistiocytosis is a life-threatening syndrome characterized by overwhelming immune activation. A steroid and chemotherapy-based regimen remains as the first-line of therapy but it has substantial morbidity. Thus, novel, less toxic therapy for hemophagocytic lymphohistiocytosis is urgently needed. Although differences exist between familial hemophagocytic lymphohistiocytosis and secondary hemophagocytic lymphohistiocytosis, they have many common features. Using bioinformatic analysis with familial hemophagocytic lymphohistiocytosis and systemic juvenile idiopathic arthritis, which is associated with secondary hemophagocytic lymphohistiocytosis, we identified a common hypoxia-inducible factor 1A (HIF1A) signature...

Experimental autoimmune encephalomyelitis (EAE) induced by active immunization of C57BL/6 mice with peptide from myelin oligodendrocyte protein (MOG35-55), is a neuroinflammatory, demyelinating disease widely recognized as an animal model of multiple sclerosis (MS). Typically, EAE presents with an ascending course of paralysis, and inflammation that is predominantly localized to the spinal cord. Recent studies have further indicated that inflammation - in both MS and EAE - might initiate within the meninges and propagate from there to the underlying parenchyma...

Plasmacytoid dendritic cells (pDCs), a main source of type I interferon in response to viral infection, are an early cell target during lymphocytic choriomeningitis virus (LCMV) infection, which has been associated with the LCMV's ability to establish chronic infections. Human blood-derived pDCs have been reported to be refractory to ex vivo LCMV infection. In the present study we show that human pDC CAL-1 cells are refractory to infection with cell-free LCMV, but highly susceptible to infection with recombinant LCMVs carrying the surface glycoprotein of VSV, indicating that LCMV infection of CAL-1 cells is restricted at the cell entry step...

Layered transition metal dichalcogenides (TMDCs), such as MoS<sub>2</sub>, WSe<sub>2</sub>, and WS<sub>2</sub>, are exciting two-dimensional (2-D) materials because they possess tunable optical and electrical properties that depend on the number of layers. In this study, the nanoscale photoluminescence (PL) characteristics of the p-type WSe<sub>2</sub> monolayer, and WSe<sub>2</sub> layers hybridized with the fluorescent dye Cy3 attached to probe DNA (Cy3/p-DNA), have been investigated as a function of the concentration of Cy3/DNA by using high-resolution laser confocal microscopy (LCM)...

Nociceptors are a particular subtype of dorsal root ganglion (DRG) neurons that detect noxious stimuli and elicit pain. Although recent efforts have been made to reveal the molecular profile of nociceptors in normal conditions, little is known about how this profile changes in pathological conditions. In this study we exploited laser capture microdissection to specifically collect individual injured and non-injured nociceptive DRG neurons and to define their gene profiling in rat spared nerve injury (SNI) model of neuropathic pain...

The heterogeneous nature of most human organs and tissues represents a common challenge when analyzing specific structures or cells. Laser capture microdissection (LCM) enables isolation of pure cells from a mixed population of cells or tissue samples via usage of laser energy. Combined with high-throughput gene or protein techniques, compartment specific analysis elucidating the role of specialized cell types in physiological or pathophysiological activity can be performed. This chapter describes the crucial steps that have to be taken into consideration when designing and conducting a LCM project...

We report a case of acute recurrent meningitis in an HIV-positive immunocompetent woman. In this case, a 34-year-old African woman with a known HIV infection presented with symptoms of acute meningitis. She was on combination antiretroviral therapy with abacavir, lamivudine, and nevirapine. Her HIV RNA level was <70 IU/mL, and CD4 counts were 640 cells/mm(3). This indicates that she was not immunocompromised. She was febrile on examination, with marked neck stiffness. Her cerebrospinal fluid revealed raised white cell counts with 100% lymphocytes and mildly raised protein...
