Delwig A, Chaney S, Bertke A, Verweij J, Quirce S, Larsen D, Yang C, Buhr E, VAN Gelder R, Gallar J, Margolis T, Copenhagen D (2018) Melanopsin expression in the cornea. Vis Neurosci 35:E004. doi: 10.1017/S0952523817000359 PMID: 29905117

Objective: To determine melanopsin expression in cornea.

Summary: Found no light-evoked activation of melanopsin-expressing fibers in cornea or in cell bodies in the TG; melanopsin protein might serve other sensory functions in the cornea. One justification for this idea is that melanopsin expressed in Drosophila photoreceptors can serve as a temperature sensor.

Usage: For the primary staining, we used Anti-Melanopsin at 1:5000 for 3 days.

Stabio ME, Sabbah S, Quattrochi LE, Ilardi MC, Fogerson PM, Leyrer ML, Kim MT, Kim I, Schiel M, Renna JM, Briggman KL, Berson DM (2018) The M5 cell: A color-opponent intrinsically photosensitive retinal ganglion cell. Neuron 97:150-163. doi: 10.1016/j.neuron.2017.11.030 PMID: 29249284

Objective: To provide a fuller description of the least understood ipRGC type, the M5 cell, and discovered a distinctive functional characteristic— chromatic opponency (ultraviolet excitatory, green inhibitory).

Summary: M5 cells send axons to the dLGN and are thus positioned to provide chromatic signals to visual cortex. These findings under- score that melanopsin’s influence extends beyond unconscious reflex functions to encompass cortical vision, perhaps including the perception of color.

Usage: M5 cells have the weakest melanopsin responses of all known ipRGC types. The intrinsic melanopsin response (~10 pA) in M5 cells is at least an order of magnitude smaller than the extrinsic, synaptically mediated response.

Objective: To identify a new strategy for postoperative pain management, this study investigated the analgesic effects of allopregnanolone (Allo) in an incisional pain model, and its effects on the activities of the primary afferent fibers at the dorsal horn.

Summary: Systemic administration of Allopregnanolone inhibited mechanical allodynia and activities of the primary afferent fibers at the dorsal horn in a rat postoperative pain model. Allopregnanolone was proposed as a candidate for postoperative pain management.

Usage: Fluorescence immunohistochemistry: Six sections per animal were labeled with primary antiserum, rabbit anti-NK-1R (1:3000).

Objective: To examine the potential utility of an alternative, mesenchymal-like cell (MSCs) source, derived from induced pluripotent stem cells, termed induced mesenchymal progenitor cells (MiMPCs) to produce bioactive factors and support nerve regeneration.

Summary: The findings suggest MiMPCs as a renewable, candidate source of therapeutic cells and a potential alternative to MSCs for peripheral nerve repair, in view of their ability to promote nerve growth by producing many of the same growth factors and cytokines as Schwann cells and signaling through critical neurotrophic pathways.

Khan N, Muralidharan A, Smith MT (2017) Attenuation of the infiltration of angiotensin ii expressing CD3+ T-cells and the modulation of nerve growth factor in lumbar dorsal root ganglia – a possible mechanism underpinning analgesia produced by EMA300, an Angiotensin II type 2 (AT2) receptor antagonist. Front Mol Neurosci 10:389. doi: 10.3389/fnmol.2017.00389 PMID: 29200998

Objective: To investigate the cellular and molecular mechanism of action of selective small molecule angiotensin II type 2 (AT2) receptor antagonists in the alleviation of peripheral neuropathic pain.

Summary: The analgesic effect of EMA300 in CCI-rats involves multimodal actions that appear to be mediated at least in part by a significant reduction in the otherwise increased expression levels of Ang II as well as the number of Ang II-expressing CD3+ T-cells in the ipsilateral lumbar DRGs of CCI-rats.

Usage: Immunocytochemistry; specifically labeled HEK cells expressing the AT2 but not the AT1 receptor or the non-transfected HEK-cells.

Objective: Pluripotent stem cells are attractive sources of cells for regenerative medicine, because large numbers of therapeutically useful cells can be generated. However, a detailed understanding of how to differentiate clinically relevant cell types from stem cells is fundamentally required.

Summary: Identification of cells resembling periocular mesenchyme (POM) cells in the adult cornea, located in a niche between the trabecular meshwork and peripheral endothelium. The generation and expansion of POM is an important step in the generation of a number of cells types that could prove to be clinically useful for a number of diseases of the cornea.

Usage: 1:200 for flow cytometry and immunofluorescence.

Objective: To determine the effects of exposure to Mn, Pb, or Cd on serotonin levels, monoamine oxidase (MAO) activity, and serotonin transporter (SERT) levels in the blue mussel Mytilus edulis.

Summary: The results clearly indicate that low environmental concentrations of Mn, Pb, and Cd affect the serotonin system in blue mussels.

Usage: Membrane was exposed to anti-SERT primary antibody diluted 1:1000 in 5% PBS skimmed milk for 1.5 h at room temperature, then rinsed twice in deionized water, washed 3 times for 5 min in PBS, and rinsed 4 times in deionized water.

Mol Med Rep 17:1166-1172. doi: 10.3892/mmr.2017.7971 PMID: 29115506

Objective: To investigate the effect of angiotensin II (Ang II) on monocyte chemoattractant protein‑1 (MCP‑1) expression and the underlying mechanism in osteoblasts.

Summary: These data indicate that Ang II-enhanced ROS production and activated NF‑κB signaling via AT1R, thus upregulating MCP‑1 expression in osteoblasts.

Usage: Western Blot; the membranes were blocked with 5% fat‑free milk and probed with anti‑AT1R (1:600).
