Objective: To investigate the expression of connective tissue (Collagens I and III), glia and neuronal markers in the testis of the African giant rat.

Summary: The cyto-architecture of the testis was typical in the African giant rat. The connective tissue expressed in the juvenile and adult group, signaling of glial-like cells were seen in the perivascular region across the experimental groups. Immuno-localization of neuronal cells was seen in the interstitial spaces across all the groups, but with more expressions in the juvenile.

Objective: To study the impact of respiratory motor neuron death.

Summary: Intrapleural CTB-SAP mimics aspects of ALS. Seven days of CTB-SAP enhances respiratory plasticity.

Usage: Bilateral intrapleural injections of: 1) CTB-SAP (25 μg), or 2) unconjugated CTB and SAP (control).

J Neurochem 142(5):620-623.. doi: 10.1111/jnc.14100

Summary: In the study published in 2017, Sharma and colleagues report that the wake-promoting BF cholinergic neurons are critically involved in the acute alcohol-induced sleep promoting response and that extracellular adenosine buildup in the BF mediates this response. Using 192-IgG-SAP (Cat. #IT-01), they ablated BF cholinergic neurons unilaterally and compared extracellular adenosine levels on lesioned versus non-lesioned sides after local delivery of alcohol via reverse microdialysis. They found that adenosine levels were significantly lower (nearly 50%) on the side with a loss of cholinergic neurons.

Summary: This project examined the sleep-promoting effect of alcohol and which neurons in the brain are involved in the process. 192-IgG-SAP (Cat. #IT-01; 0.3 µg/500 nL/side) was administered through bilateral basal forebrain infusions in rats. Based on the results, the authors suggest that alcohol promotes sleep by increasing extracellular adenosine via its action on cholinergic neurons of the basal forebrain.

Objective: To investigate whether paired-like homeobox 2b  (Phox2b)-expressing NTS neurons are recruited in hypercapnic ventilatory response (HCVR)  and whether these neurons exhibit intrinsic chemosensitivity.

Summary: Respiratory deficits caused by injection of SSP-SAP into the NTS are attributable to proportional lesions of CO2/H+-sensitive Phox2b-expressing neurons.

Usage: Two protocols were applied for SSP-SAP injections. In immunostaining experiments, to determine how many Phox2b-containing cells were destroyed, a total volume of 100 nl of PBS containing 6 ng of SSP-SAP (3 ng in 50 nl; 2 injections) was injected into one side of the NTS and the contralateral NTS was used as a control (no injection).  For in vivo experiments, to determine whether loss of Phox2b cells led to impaired HCVR, bilateral injections with a total volume of 200 nl of PBS containing 6 ng (1.5 ng in 50 nl per injection; 2 injections per side) or 12 ng (3 ng in 50 nl per injection; two injections per side) of toxin into NTS.  Breathing was studied in conscious, freely moving mice treated with SSP-SAP and Blank-SAP.

Brick, R (2017) Induced pluripotent stem cell-derived mesenchymal progenitor cells: Promotion of neuritogenesis and axon elongation through neurotrophin and cytokine production. University of Pittsburgh Thesis.

Objective: To test if mesenchymal progenitor cells (MiMPCs), originally derived from mesenchymal stem cells (MSCs), have the same ability to support neuronal regeneration as the parent MSC.

Summary: Results show that MiMPCs can secrete neurotrophic factors after neuroinductive treatment and can produce factors to improve neurite outgrowth in a chick embryonic dorsal root ganglion (DRG) model. These findings suggest that neurotrophically induced-MiMPCs (NI-MiMPCs) may be considered a suitable substitute cell type to support nerve growth.
