Summary: The authors speculated that type II cells might be ipRGCs. This was later verified by the strong immunostaining of type II cells in response to the melanopsin antibody UF006 (100%, 141 of 141 cells collected from 5 retinas, Figs. 6B1–B3), which probes multiple ipRGC subtypes.

Objective: To learn more about the role of Wnt signaling in vaginal epithelium (VE) homeostasis.

Summary: Data define heterogeneity in VE and identify VE stem cells. It was shown that canonical Wnt/b-catenin signaling is required for the proliferation and differentiation of VE stem cells.

Objective: To assess the impact of Quantum Dots (QDs) alone and QDs conjugated to Saporin, on substantia nigra microglia and dopamine neurons.

Summary: QDs might be a viable route for toxicant delivery and also have an added advantage of being fluorescently visible. Ultimately, we found SNc neurons to be exceptionally vulnerable to QD-saporin and suggest that this could be a novel targeted approach to model Parkinson’s Disease-like inflammatory pathology.

Usage: Biotin-labeled saporin chicken polyclonal was mixed with QDs coated with streptavidin. 2  μl of QDs (1 μM) were mixed with 2  μL of biotinylated saporin (56 μM) and 76  μL of phosphate buffer solution was added.

Summary: The discovery of descending neural circuitry to drive the itch-scratching cycle may provide potential therapeutic targets in the central nervous system for the management of chronic itch.

Usage: To ablate the spinal GRPR+ neurons, mice were intrathecally injected with Bombesin-SAP or Blank-SAP (400 ng/5 mL).

Objective: To investigate the effect of binge-like methamphetamine (MA) dosing on brain-derived neurotrophic factor (BDNF) levels and its receptors, trkB and p75NTR.

Summary: The binge-like regimen of MA affects expression of BDNF and its receptors, particularly the trkB receptor, in a time and region dependent manner, and highlights the importance of the frontal cortex and the striatum in the response following MA binge-like dosing.

Objective: To test the hypothesis that A2A receptor antagonism promotes phrenic motor neuron survival and preserves diaphragm function when faced with toxic, neurodegenerative insults that lead to phrenic motor neuron death.

Summary: The authors utilized a novel neurotoxic model of respiratory motor neuron death using intrapleural injections of CTB-SAP. A2A receptors contribute to neurotoxic phrenic motor neuron death, an effect mitigated by A2A receptor antagonism.

Usage: Intrapleural administration of CTB-SAP (25 μg per side) causes: 1) profound phrenic motor neuron death (~5% survival); 2) ~7-fold increase in phrenic motor neuron A2A receptor expression prior to cell death; and 3) diaphragm muscle paralysis (inactive in most rats; ~7% residual diaphragm EMG amplitude during room air breathing).

Objective: To investigate whether there is a molecular mechanism underlying the regulation of LTBP1-TGF-b signaling by the BH4-biosynthesis pathway.

Summary: GTP cyclohydrolase I (GTPCH), 6-pyruvoyltetrahydropterin synthase (PTPS), and sepiapterin reductase (SR) are sequentially responsible for de novo synthesis of tetrahydrobiopterin (BH4), a known cofactor for nitric oxide synthase (NOS). PTPS metabolic activity is required for colorectal tumor cell growth under hypoxia.
