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.

Desperately Seeking Data

Answering the Bell
We continue to seek data using our cells. We offer a reward of 25 USD Starbucks' Gift Card.

We were pleased to receive a recently published study from Dr. Mahendran Subramanian of Keele University. In this study, researchers showed that oscillating nanomagnetic gene transfection could be used to successfully transfect SH‐SY5Y cells as well as our primary hippocampal and cortical neurons on different days in vitro. This novel technique was used to effectively deliver genetic material into various cell types, resulting in high transfection efficiency and viability.

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.

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.

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.

New Schwann Cells Now $695/500,000 Cells

Priced to Buy and Try!
Schwann cells play important roles in the development, function, and regeneration of peripheral nerves. When an axon is dying, the Schwann cells surrounding it aid in its digestion, leaving an empty channel formed by successive Schwann cells, through which a new axon may then grow from a severed end.

We want to make it easy for you to buy and try these verdant cells. Also, we have a full refund or replacement should they not meet your expectations.

Detecting Expression of CAS9

Gain Trust That Your Gene Editing is on Target CRISPR/Cas9 is a hot genome-editing technology. However, the high frequency of off-target activity is a major issue.
One way to make sure CAS9 is being properly expressed is using markers against related proteins.

We are please to introduce our CAS9 markers. We plan on adding to these in the near future.

Image: Transfected Hek293 cells overexpressing the N-terminal 1-608 amino acids of S. pyogenes Cas9 . The cells were stained with MO22174 in red, and these cells also appear yellow since we counterstained with our rabbit Cas9 antibody, RA22126 to the same construct in green, giving a yellow color. The N-terminal construct contains a nuclear localization sequence and so is predominantly nuclear in localization. Most Hek293 cells in this field are not transfected so only the nuclei of these cells can be visualized with the blue DAPI DNA stain.

Canniboids and Pain Relief

Could The CB1-TRPV1 Crosstalk be a Target
Our pain marker-TRPV1-was recently referenced in an interesting study. Here researchers suggest that spatial distribution of the CB1 receptor and TRPV1 contributes to the complexity of their functional interaction.

They conclude: "Therefore, in order to utilise the analgesic potential of endogenous anandamide fully in PSN, ways to interfere with the mechanisms, through which the CB1 receptor promotes anandamide-responsiveness and sensitisation of TRPV1, must be identified. Due to the co-expression of TRPV1 and the CB1 receptor in various areas of the brain, the CB1 receptor – TRPV1 crosstalk we characterised in the present study could also have relevance in brain signal processing."

Chen J, Varga A, Selvarajah S, Jenes A, Dienes B, Sousa-Valente J, Kulik A, Veress G, Brain SD, Baker D, Urban L, Mackie K, Nagy I. Spatial Distribution of the Cannabinoid Type 1 and Capsaicin Receptors May Contribute to the Complexity of Their Crosstalk. Sci Rep. 2016 Sep 22;6:33307. doi: 10.1038/srep33307.

The SDS-FRL method reveals two major types of CB1 receptor and TRPV1 spatial distribution in DRG neurons. (A,B) Double immunogold labelling for TRPV1 (12 nm particles; arrows) and the CB1 receptor (5 nm; arrowheads) reveals that the immunoreactivity for both proteins is moderate (A) to strong (B) on the protoplasmic face (P-face) but not on the exoplasmic face (E-face) of plasma membrane of PSN. In some patches of putative somatic membrane of PSN, the great majority of immunoparticles for TRPV1 and CB1 are isolated from each other (A), whereas on other patches of the membrane immunoparticles for TRPV1 and CB1 form co-clusters (arrow + arrowhead in B). Note the occasional co-clustering of particles labelling TRPV1 (double arrows in B). Scale bars = 0.2 μm
Methods: Sodium dodecyl sulfate (SDS)-digested freeze-fracture replica immunolabeling Immunohisto-chemical labeling for electron microscopy was performed. Briefly, adult (150–200 g) male Sprague-Dawley rats (n = 4) were anesthetized with sodium pentobarbital (50 mg/kg, i.p.), and perfused transcardially with 25 mM PBS, followed by 2% paraformaldehyde and 15% saturated picric acid in 0.1 M phosphate buffer (PB). Sections from DRGs were cut at a thickness of 110 μm. The slices were cryoprotected in a solution containing 30% glycerol in 0.1 M PB and then frozen by a high-pressure freezing machine (HPM 100; Leica, Austria). Frozen samples were inserted into a double replica table and fractured into two pieces at −130 °C and replicated by carbon deposition (5 nm thick), platinum (2 nm), and carbon (15 nm) in a freeze-fracture replica machine (BAF 060; BAL-TEC, Lichtenstein). They were digested in a solution containing 2.5% SDS and 20% sucrose in 15 mM Tris-HCl at 80 °C for 18 h then at 60 °C for 18 h. The replicas were washed in 25 mM PBS containing 0.05% bovine serum albumin (BSA; Roth, Germany) and then incubated in a blocking solution containing 5% BSA for 1 h. Subsequently, replicas were incubated in a mixture of primary antibodies (TRPV1 raised in guinea pig against the 22 amino acids of the C terminus (YTGSLKPEDAEVFKDSMVPGEK; Neuromics, USA), the dilution was 1:1000 and CB1 receptor (Prof. K. Mackie, raised in goat; Veress et al. 2014), dilution was 1:4000) in 50 mM Tris-buffered saline (TBS) containing 1% BSA. After several washes, replicas were reacted with a mixture of gold-coupled donkey anti-guinea pig (for TRPV1; 12 nm) and rabbit anti-goat (for CB1, 5 nm) secondary antibodies (1:30; BioCell Research Laboratories, Cardiff, UK) in 25 mM TBS containing 5% BSA. The anti-TRPV1 antibody from Neuromics provided better staining in the replicas than then the anti-TRPV1 antibody from Chemicon, which we tried in a pilot study. They were then washed and picked up on 100-mesh grids. The specificity of the antibodies was tested on tissues dissected from TRPV1 and CB1 knock out mice.

We will keep you posted as we discover new research on targeting CB1 for pain. That said, could this crosstalk be central to medical marijuana and its ability to ameliorate certain forms of pain?

Your Neuron-Glia Co-Cultures Deserve the Best

There is a lot of cross talk between neurons and glia. In neuro-immuno and neuro-degenerative diseases this cross talk is dysregulated. Robust neuron-glia co-cultures are needed for drug discovery and basic research.Here is a study that references use of co-culturing to study the interactive effects of the viral protein HIV-1 Tat lipopolysaccharide (LPS) on enteric glia and neurons.

Here is a study that references use of co-culturing to study the interactive effects of the viral protein HIV-1 Tat lipopolysaccharide (LPS) on enteric glia and neurons. In order to optimize the co-culturing our Media, Coatings and GDNF growth factor are used. Joy Guedia, Paola Brun, Sukhada Bhave, Sylvia Fitting, Minho Kang, William L. Dewey, Kurt F. Hauser; Hamid I. Akbarali. HIV-1 Tat exacerbates lipopolysaccharide-induced cytokine release via TLR4 signaling in the enteric nervous system. Scientific Reports 6, Article number: 31203 (2016) doi:10.1038/srep31203.

Figures: (A) Representative confocal microscopic images of enteric β-III tubulin (green) and glial fibrillary protein (GFAP- red) showing the presence of neurons and glia isolated from the adult mouse LMMP. (B) IL-6 release from isolated mouse neuron/glia co-culture treated with 100 nM Tat, 100 ng/ml LPS or Tat+ LPS for 16 h measured by ELISA.

(E) TNF-α release from mouse LMMP treated with 100 nM Tat, 100 ng/ml LPS or Tat+ LPS for 16 h measured by ELISA.

Protocol: Myenteric neurons and glia were isolated as described recently41. Briefly, after euthanizing mice, the ileum was immediately removed and placed in ice-cold Krebs solution (118 mM NaCl, 4.6 mM KCl, 1.3 mM NaH2PO4, 1.2 mM MgSO4, 25 mM NaHCO3, 11 mM glucose and 2.5 mM CaCl2) bubbled with carbogen (95% O2/5% CO2). The ileum contents were discarded by passing Krebs solution using a syringe. The ileum was then divided into short segments which were threaded longitudinally on a plastic rod through the lumen and the longitudinal muscle containing the myenteric plexus (LMMP) strips were obtained using a cotton-tipped applicator. LMMP strips were rinsed three times in 1 ml Krebs and gathered by centrifugation (350 × g, 30 sec). LMMP strips were then minced with scissors and digested in 1.3 mg/ml collagenase type II (Worthington) and 0.3 mg/ml bovine serum albumin in bubbled Krebs (37 °C) for 1 h, followed by 0.05% trypsin for 7 min. Following each digestion, cells were triturated and collected by centrifuge (350 x g for 8 min). Cells were then plated on laminin (BD Biosciences) and poly-D-lysine coated coverslips in Neurobasal A media containing B-27 supplement, 1% fetal bovine serum, 10 ng/ml glial cell line-derived neurotrophic factor (GDNF, Neuromics, Edina, MN), and penicillin/streptomycin.

Perky ERKies and Depression

ERK1/2 Signaling and Depression

Extracellular signal-regulated kinase 1/2- (ERK1/2-) mediated cellular signaling plays a major role in synaptic and structural plasticity. Although ERK1/2 signaling has been shown to be involved in stress and depression. Phosphorylation of the receptor is important for maintaining healthy signaling, reduction of oxidative stress and induction of growth factors.

We are pleased that our ERK1/2 markers have been published in these type of studies. Here's a recent one: MARIA CONCETTA OLIANAS, Simona Dedoni, and PIER LUIGI ONALI. LPA1 mediates antidepressant-induced ERK1/2 signalling and protection from oxidative stress in glial cells. Published online before print September 7, 2016, doi: 10.1124/jpet.116.236455. ...Membranes were incubated overnight at 4 °C with one of the following primary antibodies: anti-phospho-ERK1 (Thr202/Tyr204) / ERK2(Thr185/Tyr187) (RA 15002) (1:15,000) (Neuromics, Northfield, MN, USA.

We will continue to post updates on this important topic

Multiplexed Protein Array for Immunologists

Assay 1,631 Antibodies in Under 8 Hours!
The RayBio® Immunome Protein Arrays are multiplex protein immunoassays for numerous research applications. Correctly folded, functional proteins are immobilized onto a solid glass slide surface. The slides can then be probed with serum or small molecules and used in protein-antibody studies, small-molecule inhibition of kinase studies, protein-protein studies, methylation studies or DNA binding studies. Our main immunome array product offering contains 1,631 proteins. Smaller custom arrays are also available.

Each 75mm x 25mm glass slide is spotted with 4 identical protein arrays (also called “subarrays”), each with 1631 correctly folded and functional spotted proteins! Each protein is attached to the streptavidin-coated slide exclusively via a biotinylated affinity tag, specifically the biotin carboxyl carrier protein (BCCP) domain of the E. coli acetyl CoA carboxylase. This affinity tag was chosen because the BCCP domain must be folded into its native 3-dimensional structure in order to become biotinylated. If the expressed protein mis-folds the BCCP tag will also mis-fold, preventing biotinylation. If the protein folds correctly then folding of the BCCP tag should be unhindered and biotinylation will result. This property allows only correctly folded proteins to be bound to the slide.

Research Applications

  • Screening protein-antibody interactions 
  • Performing small-molecule-kinase inhibition experiments 
  • Screening protein-protein interactions 
  • Performing DNA-binding experiments Performing methylation assays

In Depth Analysis of Differentiating Neural Stem Cells

Foundation for Future Therapies

Here we share an example of this analysis. Results from worldwide research is now being made available via hPSCreg: Ilyas Singec, Andrew M. Crain, Junjie Hou, Brian T.D. Tobe, Maria Talantova, Alicia A. Winquist, Kutbuddin S. Doctor, Jennifer Choy, Xiayu Huang, Esther La Monaca, David M. Horn,5 Dieter A. Wolf, Stuart A. Lipton, Gustavo J. Gutierrez, Laurence M. Brill, and Evan Y. Snyder. Quantitative Analysis of Human Pluripotency and Neural Specification by In-Depth (Phospho)Proteomic Profiling. Stem Cell Reports (2016),

Images: MDK Expression in Pluripotent and Differentiated Cells and Disruption of Neural Conversion by a Monoclonal Antibody against MDK (A) Representative immunocytochemical analysis of MDK expression by hESCs (WA09), skin fibroblasts (FB, line HS27), and fibroblasts (HS27) after reprogramming to hiPSCs. Scale bars represent 100 μm. (B) Western blot showing that MDK was not detected in HS27 fibroblasts but was expressed in WA09 hESCs and hiPSCs from HS27 fibroblasts, and was upregulated in differentiating cells (EBs and hNSCs from hESCs). Probing for GAPDH demonstrated similar loading of the lanes. (C) A monoclonal antibody against MDK did not impair pluripotent self-renewal of hESCs. Antibody concentrations are shown. (D) The percentage of pluripotent cells expressing OCT4 and NANOG did not differ significantly between anti-MDK and isotype control antibody treatment (3.0 μg/mL). Error bars represent SEM; n = 5. (E) qRT-PCR showed that a monoclonal antibody against MDK (1.5 μg/mL) inhibits neural gene expression during 6-day DAP treatment. Error bars represent mean + SEM, n = 3. ∗p less than  0.05. (F) Western blot analysis confirmed the inhibitory effect of anti-MDK on early neural marker expression (OTX1, PAX6), despite DAP treatment, in contrast to the isotype control. (G) Immunocytochemical evidence that neural conversion is inhibited by the anti-MDK antibody (1.5 μg/mL) during 6-day DAP treatment. Few cells induced PAX6 expression in the presence of anti-MDK antibody (right panel). Scale bar represents 200 μm. (H) Western blot analysis and time course of hESCs differentiated for 6 days with recombinant MDK alone (100 ng/mL) or a combination of the DAP cocktail and MDK (25 or 100 ng/mL) suggest that MDK specifically promotes neural commitment of hPSCs. SOX17, MIXL1, and Brachyury were not induced by MDK. In contrast, controls treated with fetal bovine serum (FBS) for 6 days, which stimulates multi-lineage differentiation of hPSCs, induced these non-neural markers.
This level of basic research yield knowledge that is important for the development of future cell based therapies for Neuro-related Diseases. We will continue to post updates here.
