Complement activation in the peripheral nervous system following the spinal nerve ligation model of neuropathic pain

ABSTRACT: Neuroinflammatory and neuroimmune mechanisms, as exemplified by infiltrating immune cells and activation of resident endothelial/glial cells, respectively, are known to be involved in the establishment and maintenance of chronic pain. An immune system pathway that may be involved in the activation of both immune and glial cells is complement. The complement pathway is made up of a large number of distinct plasma proteins which react with one another to opsonize pathogens and induce a series of inflammatory responses to help fight infection. Cleaved products and complexes produced by complement activation are responsible for a range of effects including mediation of immune infiltration, activation of phagocytes, opsonization/lysis of pathogens and injured cells, and production of vasoactive amines such as histamine and serotonin. Gene-expression microarray-analysis was performed on the rat spinal nerve ligation (SNL) model of neuropathic pain Keywords: organ type comparison, disease state analysis and drug treatment

Transcription profiling of rat model of neurpathic pain, treatment groups naive+ vehicle (2) naive + GPN (3) sham + vehicle (4) SNL + vehicle (5) SNL + GPNC

Gene-expression microarray-analysis was performed on the rat spinal nerve ligation (SNL) model of neuropathic pain Experiment Overall Design: For gene expression analysis, rats from five experimental groups were sacrificed 19â??21 days after surgery: (1)NaÃ¯ve+ vehicle; (2) NaÃ¯ve + GPN; (3) sham + vehicle; (4) SNL + vehicle; (5) SNL + GPN. Tissue was collected from whole brain, hemisected spinal cord, mid thigh sciatic nerve, and L4, L5 and L6 dorsal root ganglia (DRG), both ipsilateral(ipsi) and contralateral (contra) to the injury. In addition,â??â??organ recitalâ??â?? tissues were harvested from naÄ± Â¨ve animals: adrenal,aorta, fetal brain, kidney, liver, quadriceps muscle, spleen,submaxillary gland, and testis and 15 other tissues.For each experimental group and tissue, samples rapidly frozen on dry ice were separated into two pools(Pool 1 and Pool 2), consisting of half or 4-6 animals each.Pool 1 total RNA was subjected to standard methods on Affymetrix GeneChip Arrays using rat U34 A, B, and C.

A novel functional role for the serine protease inhibitor SerpinA3N and its substrate leukocyte elastase in neuropathic pain

Project description:Two out-bred rat selection lines were separated to produce different hypersensitivity phenotypes following nerve injury. These lines were termed High Pain and Low Pain (HP or LP). Each sub-strain was either subject to a Sham surgery or a Spinal Nerve Ligation (SNL) surgery to the L4 and L5 spinal nerves. Three days following surgery L4/L5 Dorsal Root Ganglia (DRG) were dissected from these animals. For the rat line separation protocol see: Devor M, Raber P (1990) Heritability of symptoms in an experimental model of neuropathic pain. Pain 42:51-67. 12 Hybridizations, 3 per condition; Sham HP DRG; 3 day SNL HP DRG; Sham LP DRG; 3 day SNL LP DRG.

mRNA expression profiling in the spinal nerve ligation model of neuropathic pain in rats

Project description:Expression profiling of L4 and L5 Dorsal Root Ganglion (DRG) in the spinal nerve ligation model of neuropathic pain. The goal of the study was to identify genes involved in neuropathic pain This series of samples comprises of contralateral and ipsilateral L4 and L5 DRG tissue collected 4 weeks after rats underwent a L5 spinal nerve ligation (SNL) or a sham operation with no L5 spinal nerve ligation. This defines 8 groups (i) contralateral L4 DRG from the sham cohort (n=5), (ii) ipsilateral L4 DRG from sham cohort (n=5), (iii) contralateral L4 DRG from SNL cohort (n=5), (iv) ipsilateral L4 DRG from the SNL chort (n=5), (v) contralateral L5 DRG from the sham cohort (n=5), (vi) ipsilateral L5 DRG from sham cohort (n=5), (vii) contralateral L5 DRG from SNL cohort (n=5), (viii) ipsilateral L5 DRG from the SNL cohort (n=5)

Gene expression signatures for lumber 5 dorsal horn of spinal cord in spinal nerve ligation (SNL) mice with WTD intervention

Project description:For development of gene expression of L5 spinal tissue in SNL mice, L5 spinal nerve was first tightly ligated to construct the neuropathic pain model, and sham-operated group as a control. After chronic administrations of vehicle (distilled water, 10 mg/kg) or WTD (12.60 g/kg, p.o.), L5 spinal cord of dorsal horn were collected, and then, Agilent Whole Mouse Genome Microarray 4×44K expression profiling were employed as a discovery platform to identify genes with the potential to provide basis for the clinical application of WTD for neuropathic pain. A 579-gene consensus signature was identified that distinguished between sham and SNL samples, and a 456-gene consensus signature was identified that distinguished between WTD and SNL samples. Expression of 12 genes (Crk1, Fgf13, Fgfr1, Crk1, Adrbk1, Erbb3, Gnas, Vegfa, Crk1, Erbb3, Drd2, Gnas) were identified as the efficacy of differentially expressed genes.

RNA-seq of rat dorsal root ganglia after ligation to investigate central nervous system transcriptomics in chronic pain using agnostic splice site discovery methods

Project description:The study pursued dual goals: To advance mRNA-seq bioinformatics towards unbiased transcriptome capture and to demonstrate its potential for discovery in neuroscience by applying the approach to an in vivo model of neurological disease. We found that 12.4% of known genes were induced and 7% were suppressed in the dysfunctional (but anatomically intact) L4 dorsal root ganglion (DRG) 2 weeks after L5 spinal Nerve Ligation (SNL). A new algorithm for agnostic mapping of pre-mRNA splice junctions (SJ) achieved a precision of 97%. mRNA-seq of L4 DRG 2 weeks and 2 months after L5 spinal nerve ligation. CONTROL and SNL were used to identify differential gene expression between chronic pain and standard conditions in Rattus norvegicus. CONTROL and SNL and PILOT were used to perform 'agnostic splice site discovery' in the nervous system transcriptome in Rattus norvegicus

DNA methylation reprogramming after spinal nerve injury

Project description:Purpose: Nerve injury-induced hyperactivity of primary sensory neurons in the dorsal root ganglion (DRG) contributes critically to chronic pain development, but its underlying mechanisms remain incompletely understood. Chronic neuropathic pain has a clear epigenetic component, however, most studies so far have focused on histone modifications. We determined changes of DNA methylation in the rat DRG, spinal cord, and prefrontal cortex after spinal nerve ligation (SNL).

Transcription profiling by array of dendritic cells from three different human donors to characterize the impact of differential HIV opsonization on dendritic cell modulation

Project description:The aim of this study was to characterize the impact of differential HIV opsonization on DC modulation. DCs are the most potent antigen-presenting cells and among the first cells HIV is attaching to. HIV spontaneously activates the complement system even in the absence of specific antibodies and is therefore found opsonized with complement fragments from the beginning of infection. Gene expression profiles of DCs from three different human donors and treated for 24 hrs with 100 ng/ml LPS, 300 ng/ml non-opsonized HIV (HIV-MC), or 300 ng/ml complement-opsonized (HIV-C) were compared to those of untreated immature DCs.
