Gap Junctions (GJs) and Glaucoma

GJs Can Offer Neuroprotection
This study references use of our GFAP Antibody,

Gap junctions (GJs), intercellular channels composed of subunit connexins, can play a major role in secondary cell death by forming conduits through which toxic molecules from dying cells pass to and injure coupled neighbors. Secondary cells like glia and astrocytes are involved in this process though the precise mechanisms have yet to be defined: Abram Akopian, Sandeep Kumar, Hariharasubramanian Ramakrishnan, Kaushambi Roy, Suresh Viswanathan, and Stewart A. Bloomfield. Targeting neuronal gap junctions in mouse retina offers neuroprotection in glaucoma. J Clin Invest. doi:10.1172/JCI91948.

Rose Hip and Heart Disease

Helps Prevent Atherosclerotic Plaques

This study features the use of our ABCA1 Antibody. The ATP-binding cassette transporter (ABC) Protein called ABCA1 has a major impact on cellular and whole body cholesterol metabolism and is likely to play an important role in protecting against cardiovascular disease.

The authors conclude that rose hip is a suitable dietary supplement for preventing atherosclerotic plaques formation by modulating systemic blood pressure and the expression of RCT and inflammatory genes.Michele Cavalera, Ulrika Axling, Catarina Rippe, Karl Swärd, and Cecilia Holm. Dietary rose hip exerts anti-atherosclerotic effects and increases nitric oxide-mediated dilation in ApoE-null mice. The Journal of Nutritional Biochemistry. Available online 21 March 2017. blotting. Approximately 50 mg of tissue was homogenized in lysis buffer (50 mM Tris–HCl, pH 7.5, 1 mM EGTA, 1 mM EDTA, 1% NP40, 1 mM Na-orthovanadate, 40 mM NaF, 4 mM Na-pyrophosphate, 0.27 M sucrose, 1 mM DTT, 20 μg/ml leupeptin, 10 μg/ml antipain and 1 μg/ml pepstatin) and subsequently centrifuged at 12,000 g for 20 min at 4 °C. Protein concentration of the supernatant was determined using BCA-assay (Pierce) and 20 μg of proteins were resolved on NuPAGE 4–12% Bis-Tris Gel (Life Technologies – Carlsbad, CA) and electroblotted onto nitrocellulose membranes (Amersham, GE Healthcare – UK). The membranes were washed and incubated with primary and appropriate secondary antibodies. Primary antibodies used were: SR-B1 (ab3 - Abcam), beta-actin (A5441 – Sigma), Abca1 (MO13101 - Neuromics), Abcg1 (orb214917, Biorbyt), Abcg5 (orb5656, Biorbyt), Abcg8 (orb228808, Biorbyt), IL1b (orb101745, Biorbyt), IL6 (orb228222, Biorbyt), NF-kB (ab7970, Abcam) and HSP90 (BD610418, BD bioscience)...

RH supplementation modulates the reverse cholesterol transport pathway. (a) Liver qPCR analysis of cholesterol metabolism showed similar expression of genes involved in the synthesis and conversion of cholesterol into bile acids but increased expression of various RCT genes upon rose hip feeding (n=5–6).
(b) Protein levels of SR-B1, Abcg1 and Abcg5 were increased in the liver of RH-feeding mice (n=6). *P<.05, **P<.01 and ^P=.056 versus CTR.

TRPV1 Channels and Neuropathic Pain

Neuromics' TRPV1 Stain Neurons and Microglia for Study

TRPV1 is mainly functional in the microglia. Its activation, beyond controlling microglia reaction per se, modulated microglia-neuron communication, by promoting release of extracellular vesicles (EVs) from microglia. Indeed, EVs are important mediators of intercellular communication between microglia and brain cells: Maria Cristina Marrone, Annunziato Morabito, Michela Giustizieri, Valerio Chiurchiù, Alessandro Leuti, Marzia Mattioli, Sara Marinelli, Loredana Riganti, Marta Lombardi, Emanuele Murana, Antonio Totaro, Daniele Piomelli, Davide Ragozzino, Sergio Oddi, Mauro Maccarrone, Claudia Verderio & Silvia Marinelli. TRPV1 channels are critical brain inflammation detectors and neuropathic pain biomarkers in mice. Nature Communications 8, Article number: 15292 (2017) doi:10.1038/ncomms15292.

(a–f) Sections of cortical tissue from WT and TRPV1−/− mice, fixed after exposure to ACSF (a,d), ACSF plus vehicle (DMSO; b,e) and ACSF plus 1μM capsaicin (c,f) and immune-processed for iba-1 to stain microglia cells (in red). INSETs are zoom images taken from an area delimited by the yellow square for each condition. (g), Bar graph of percentage of cortical microglia cell phenotype (resting, ameboid, bushy and hypertrophied), in control (grey bars), vehicle- (dark grey bars) and capsaicin- treated (red bars) cortical sections from WT mice. Capsaicin treatment causes a significant shift from ramified and bushy to hypertrophied morphology. (h), Same as in ‘g’ but in cortical sections from TRPV1−/− mice. In these tissues capsaicin fails to induce morphological changes of microglia cells. Note that microglia cells in −/− tissues are already hypertrophied in control conditions (d–f,h).
Our Pain and Inflammation Research Antibodies Continue to be widely used and frequently published.

Culturing Stem Cells in 3-D

Requires Potent Media + Supplements

Neuromics is responding to the many challenges our clients face in building 3-D, in-vivo like, cell- based assays. We do this by offering the most potent Media plus Supplements like FGFS.

Here's a protocol for single cell 3-D assays using hMSCs and Hydrogels. It features use of our ISOKineTM FGF

Images: Cell-centering in cytocompatible microgels enables long-term single-cell 3D culture by preventing cell escape. a) Qualification of Dex-TA microgel crosslinking as a function of the microemulsion flow rate (Qemulsion) and concentration of the H2O2 feed ([H2O2]feed). Blue, green, and red indicate incomplete crosslinking, complete crosslinking, and H2O2 excess, respectively. b,c) Amplex Red assay to quantify the concentration of residual H2O2 ([H2O2]emulsion) in Dex-TA microgel precursor droplets and crosslinked microgels after their retrieval from the diffusion-based crosslinking platform. d) The microencapsulation procedure had no detrimental effect on short-term cell survival. e) Delayed crosslinking resulted in 4 ± 1% cell escape after 7 d of in vitro culture, as compared to 27 ± 5% cell escape when using coupled emulsification and gelation. f) The number of encapsulated cells per microgel tightly followed the Poisson distribution and remained similar throughout long-term (28 d) of in vitro culture, which confirmed that cell centering prevents cell escape. g–i) MSCs encapsulated in delayed enzymatically crosslinked microgels remained viable and metabolically active throughout 28 d of in vitro culture. j) Positive Oil Red O and k) Alizarin Red staining confirmed that l) more than 60% of the microencapsulated MSCs could differentiate into the adipogenic and osteogenic lineage, respectively. Black scale bars: 50 µm, white scale bars: 5 µm. DOI: 10.1002/smll.20160371.

Protocol for Cell Isolation and Expansion: Human MSCs were isolated from fresh bone marrow samples and cultured as previously described. The use of patient material was approved by the local ethical committee of the Medisch Spectrum Twente and informed written consent was obtained for all samples. In short, nucleated cells in the bone marrow aspirates were counted, seeded in tissue culture flasks at a density of 500 000 cells cm−2, and cultured in MSC proliferation medium, consisting of 10% FBS, 100 U mL−1 penicillin, 100 mg mL−1 streptomycin, 1% GlutaMAX, 0.2 × 10−3 m ascorbic acid, and 1 ng mL−1 bFGF (added fresh) in αMEM. Mouse insulinoma MIN6-B1 cells (provided by Dr. P. Halban, University Medical Center, Geneva, Switzerland) were cultured in MIN6 proliferation medium, consisting of 10% (v/v) FBS, 100 U mL−1 penicillin, and 100 mg mL−1 streptomycin, and 71 × 10−6 m 2-mercaptoethanol (added fresh) in DMEM. When cells reached near confluence, the cells were detached using 0.25% Trypsin-EDTA at 37 °C and subsequently subcultured or used for experimentation.

High Titer Cathepsin Antibodies

Used in Thyroid Gland Research

We strive to provide quality tools to study proteases and apoptosis. Here is a publication featuring 2 of our Cathepsin Antibodies: Jonas Weber, Joseph McInnes, Cise Kizilirmak, Maren Rehders, Maria Qatato, Eva K. Wirth, Ulrich Schweizer, Francois Verrey, Heike Heuer, Klaudia Brix. Interdependence of thyroglobulin processing and thyroid hormone export in the mouse thyroid gland. European Journal of Cell Biology. Available online 6 March 2017. goat anti-cathepsin B (GT15047; 1 in 1000, Neuromics through Acris, Herford, Germany), goat anti-cathepsin L (GT15049; 1 in 1000, Neuromics through Acris)...

Images: Protein levels of cathepsin B, D, and L in thyroids of TH transporter-deficient adult mice. Whole thyroid lysates of adult mice (5–8 months old) were separated on horizontal SDS-gels, transferred to nitrocellulose and incubated with antibodies against cathepsins B, D or L (left panels). Densitometry of the indicated bands revealed that cathepsin D protein levels were elevated significantly in Mct8/Mct10-deficient mice, whereas cathepsin B and L levels were increased in all investigated genotypes when compared to WT (right panels). 

Images: Expression and localization of cathepsin B in thyroid glands from TH transporter-deficient mice. Cathepsin B (white, red) was mainly localised in vesicles of thyrocytes of WT (A) and Mct10- (B) Mct8- (C), and Mct8/Mct10-deficient (D) animals but also associated with the apical plasma membrane domain and within the lumen of thyroid follicles (E to H, asterisks). Thyroid tissue taken from cathepsin B-deficient animals served as controls for antibody specificity, which was confirmed by lack of primary antibody reactivity (I). Vesicular staining (arrows) of cathepsin B is more pronounced and signal intensities (J) are slightly increased in both, Mct8- (G) or Mct8/Mct10-deficient (H) mouse thyroids when compared to WT (E). Representative images of 3 animals (5–8 months old) per genotype are displayed.

We will continue to post relevant stories of our markers in action.

Staining Tissue From Space Mice

Our Synaptic Marker is Used to Compare Earth vs Space Samples
Exposure to the microgravity conditions of spaceflight alleviates the load normally imposed by the Earth’s gravitational field upon the inner ear utricular epithelia. Previous ultrastructural investigations showed that spaceflight induced an increase in synapse density within hair cells of the rat utricle. However, the utricle exhibits broad physiologic heterogeneity across different epithelial regions, and it is unknown whether capabilities for synaptic plasticity generalize to hair cells across its topography. To achieve systematic and broader sampling of the epithelium than previously conducted we used immunohistochemistry and volumetric image analyses to quantify synapse distributions across representative utricular regions in specimens from mice exposed to spaceflight (a 15-day mission of the space shuttle Discovery). These measures were compared to similarly-sampled Earth-bound controls. Following paraformaldehyde fixation and microdissection, immunohistochemistry was performed on intact specimens to label presynaptic ribbons (anti-CtBP2) and postsynaptic receptor complexes (anti-Shank1A) DOI: 10.1152/jn.00240.2016.

Mature vestibular hair cells retain capabilities for structural plasticity manifested through modulation of synapse density. Investigations are ongoing that are testing the hypothesis that synapse density increases may result from exposure to centrifugation-induced hypergravity, which would provide the foundation for future research into the molecular mechanisms through which these modifications are induced. This research will provide insight and strategies for inner ear rehabilitation through the induction of synapse density increases in conditions of vestibular paresis.

Maybe zero gravity will play a role in therapies for hearing loss?

Holistic Medicine for the Brain

Mind Expansion? 

There is a slowly growing body of support for certain hallucinogenic serotonin-like molecules supporting cognitive gains, antidepressant effects and changes in brain areas related to attention, self-referential thought, and internal mentation. These molecules are present in Virola Ayahuasca and used in traditional native South American medicine.

Here researchers found that in silico systems biology analyses support 5- MeO-DMT’s anti-inflammatory effects and reveal a modulation of proteins associated with the formation of dendritic spines, including proteins involved in cellular protrusion formation, microtubule dynamics and cytoskeletal reorganization. Proteins involved in long-term potentiation were modulated in a complex manner, with significant increases in the levels of NMDAR, CaMKII and CREB, but a reduction of PKA and PKC levels. These results offer possible mechanistic insights into the neuropsychological changes caused by the ingestion of substances rich in dimethyltryptamines: Vanja Dakic, Juliana Minardi Nascimento, Rafaela Costa Sartore, Renata de Moraes Maciel, Draulio B. de Araujo, Sidarta Ribeiro, Daniel Martins-de-Souza , Stevens Rehen.

Leptin and Remyelination

Leptin Promotes Proliferation of OPCs

Demyelination occurs in many diseases of the Central Nervous System (CNS) including Multiple Sclerosis and Parkinson's Disease. Here researchers show that Leptin plays a role in the proliferation of Oligodendrocyte Precursor Cells (OPCs): These cells are critical for keeping the myelin sheath on Neurons of the CNS healthy and happy.  Ken Matoba, Rieko Muramatsu & Toshihide Yamashita. Leptin sustains spontaneous remyelination in the adult central nervous system. Scientific Reports 7, Article number: 40397 (2017) doi:10.1038/srep40397.

Our LepRB Antibody is used in this study to stain OPCs.

Figures: (a) Representative image of cultured OPCs stained with antibodies against LepRb (green) and PDGFRα (red). Scale bar: 25 μm. (b) Relative BrdU incorporation into the OPC obtained from the brain (left graph) and spinal cord (right graph). Cells were treated with recombinant leptin for 48 h (n = 4). (Left graph) P = 0.005993 (control vs 10 ng/mL), 0.045616 (control vs 100 ng/mL), (Right graph) P = 0.004456 (control vs 10 ng/mL), 0.017859 (control vs 100 ng/mL). (c) Relative BrdU incorporation into the OPC after leptin stimulation (10 ng/ml) with U0126 (20 μM), a MEK inhibitor (n = 4 for brain OPCs, n = 3 for spinal cord OPCs). (Left graph) P = 0.019753 (control vs leptin), 0.039433 (leptin vs leptin + U0126), (Right graph) P = 0.045545 (control vs leptin), 0.04486 (leptin vs leptin + U0126). (d) Representative images of western blotting (upper panels) and quantitative analysis of ERK phosphorylation (lower graph) are shown. OPCs were treated with leptin (10 ng/ml) under indicated periods (n = 3). P = 0.006352 (2 min), 0.016571 (5 min), 0.017675 (10 min), 0.024100 (15 min), 0.081342 (30 min).
We are in the process of looking for Labs to sponsor Neuromics' to isolate and purify adult human OPCs in return for receiving 2,000,000 cells. Stay tuned.

Dopamine and Morphine Tolerance

Dopamine Identified as Key Player

Our Mu Opioid Receptor antibody is used to show that blocking dopamine decreases morphine tolerance: Wen-Ling Dai, Feng Xiong, Bing Yan, Zheng-Yu Cao, Wen-Tao Liu, Ji-Hua Liu1, Bo-Yang Yu. Blockade of neuronal dopamine D2 receptor attenuates morphine tolerance in mice spinal cord. Scientific Reports 6, Article number: 38746 (2016). doi:10.1038/srep38746.

Images: (A) Double immunofluorescence staining showed that MOR (green) and D2DR (red) were co-localized in the mice spinal cord (20X magnification). Chronic morphine treatment increased the co-localization of MOR and D2DR in the spinal cord, and D2DR antagonist sulpiride (8 μg/10 μl, i.t.) reduced the increased co-expression of D2DR with MOR (n = 4). (B) Co-IP experiments showed that D2DR could interact with MOR, and the MOR/D2DR interactions were increased in the spinal dorsal horn after chronic morphine treatment for 7 days while D2DR antagonist sulpiride (8 μg/10 μl, i.t.) disrupted the interactions of the MOR/D2DR (n = 3).

Blockade of D2DR in spinal cord can disrupt the interactions between MOR and D2DR to attenuate morphine tolerance. These findings highlight the possibility of a new clinical strategy to prevent morphine antinociceptive tolerance.

Neuromics Cornerstone

Human Primary + Stem Cells and 3-D Tissue Like Models

We are pleased by growing demand for our "hard to find" primary cells and 3-D BBB model. These are proving to be engines for drug discovery and toxicology assays.

We have have the capabilities isolate cells from healthy human donors. We then grow and characterize the cells and cryo-preserve in vials of 500,000 cells. They are now ready to culture.

We are increasingly determining types of cells to add to our growing catalog by meeting the specific demand of our clients. For example, our addition of primary human schwann cells and microglia happened, because they were needed for a specific client study.
Human Schwann Cells
Our 3-D Blood Brain Barrier Model is also working well in the hands of our clients. We are receiving positive input and this is supported by repeat orders. It is designed for users to test the ability of compounds, molecules and oligos to pass the BBB and penetrate into the brain.

Our cornerstone: hard to find human primary/stem cells + 3-D tissue like assays.
We can say, "Need cells or 3-D tissue like models?  Just ask us!". Pete Shuster, CEO and Owner-direct phone: 612-801-1007 or

Need Cells From Diseased Donors?

Just Ask
Some of our customers have expressed the need for Cells that have the phenotype of a given disease. This is especially true for researchers doing drug discovery for neuro-diseases like Alzheimer's and Parkinson's.

Deriving "hard to find" cells from tissue is one of our cornerstones.
If you have need for any type of human cell(s), give us a shot. I can be reached at 612-801-1007 or Thank you. Pete Shuster,CEO and Owner, Neuromics.

Fatty Acids and IBD and Colitis

The Dangers of a High Fatty Acid Diets
Our westernized high-fat diet (HFD) is associated with the development of inflammatory bowel disease (IBD), Colitis and other intestinal related diseases and cancers. Here one the root causes is identified to elevated production of pro-inflammatory cytokine-IL-1β by macrophages. It is suspected that HFD sets off an autoimmune like cascade.

This cascade is triggered by NLRP3 inflammasomes. Our Apoptosis Kit-Magic Red-Real Time Cathepsin B is used to demonstrate these inflammasomes are activated via Cathepsin B Release: Shengnan Zhao, Zizhen Gong1, Jiefei Zhou1, Chunyan Tian, Yanhong Gao, Congfeng Xu, Yingwei Chen, Wei Cai and Jin Wu1Deoxycholic Acid Triggers NLRP3 Inflammasome Activation and Aggravates DSS-Induced Colitis in Mice. Front. Immunol., 28 November 2016 | ...Lipopolysaccharide-primed J774A.1 cells were incubated with or without DCA (100 μM, 24 h); then, the cells were stained with Lyso Tracker Green DND-26 (Invitrogen) or magic red cathepsin B fluorogenic substrate z-Arg-Arg cresyl violet (Neuromics) for 1 h, followed by Hoechst staining for half an hour. Fluorogenic signals were captured by inverted fluorescence microscope (Leica)...
