Eng MS, Kaur J, Prasmickaite L, Engesaeter BO, Weyergang A, Skarpen E, Berg K, Rosenblum MG, Maelandsmo GM, Hogset A, Ferrone S, Selbo PK (2018) Enhanced targeting of triple-negative breast carcinoma and malignant melanoma by photochemical internalization of CSPG4-targeting immunotoxins. Photochem Photobiol Sci 17:539-551. doi: 10.1039/C7PP00358G

Summary: The combination of the drug delivery technology PCI and CSPG4-targeting immunotoxins is an efficient, specific and light-controlled strategy for the elimination of aggressive cells of TNBC and malignant melanoma origin. This study lays the foundation for further preclinical evaluation of PCI in combination with CSPG4-targeting.

Usage: To obtain the immunotoxin 225.28-saporin, Streptavidin-Saporin (Cat. #IT-27; Streptavidin-ZAP), with an average of 2.5 molecules of saporin per molecule of streptavidin, was combined with biotinylated 225.28, a CSPG4-specific mouse mAb, IgG2a.

Sun X, Zhu Y, Yin HY, Guo ZY, Xu F, Xiao B, Jiang WL, Guo WM, Meng HY, Lu SB, Wang Y, Peng J (2018) Differentiation of adipose-derived stem cells into Schwann cell-like cells through intermittent induction: potential advantage of cellular transient memory function. Stem Cell Res Ther 9:133. doi: 10.1186/s13287-018-0884-3 PMID: 29751848

Objective: To improve the traditional methods for inducing the differentiation of mesenchymal stromal cells (MSCs) into Schwann cell-like cells (SCLCs).

Summary: Results indicated that the intermittent induction method is more efficient than traditional methods for inducing adipose-derived stem cells to differentiate into SCLCs.

Usage: immunofluorescence (1:500)

Vetter I (2018) Toxins in Neurobiology: New tools from old molecules. Neurosci Lett 679:1-3. doi: 10.1016/j.neulet.2018.05.008

Summary: The selective ablation of neurokinin-1 receptor-expressing neurons by SP-SAP revealed a key role for the preBötzinger complex in the generation of respiratory rhythm. Toxin-mediated neuronal ablation may also find therapeutic applications, such as the treatment of severe refractory pain in terminally ill patients by intrathecal SP-SAP which causes selective loss of neurokinin-1 receptor-expressing neurons in the spinal cord dorsal horn.

Araldi D, Ferrari LF, Levine JD (2018) Role of GPCR (mu-opioid)-receptor tyrosine kinase (epidermal growth factor) crosstalk in opioid-induced hyperalgesic priming (type II). Pain 159(5):864-875. doi: 10.1097/j.pain.0000000000001155

Objective: To determine the the mechanisms mediating the induction of opioid-induced hyperalgesia and the prolongation of prostaglandinE2-induced hyperalgesia in type II hyperalgesic priming.

Summary: Understanding the mechanisms responsible for the induction of type II hyperalgesic priming, a form of neuroplasticity in the peripheral terminal of the primary afferent nociceptor, may provide useful information for the design of drugs with improved therapeutic profiles to treat neuroplasticity induced by chronic use of opioids.

Usage: SSP-SAP was prepared in saline (5 ng/mL), and 20 mL was injected intrathecally into rats, 14 days before nociceptive tests.

Cho JS, Lee J, Jeong DU, Kim HW, Chang WS, Moon J, Chang JW (2018) Effect of placenta-derived mesenchymal stem cells in a dementia rat model via microglial mediation: A comparison between stem cell transplant methods. Yonsei Med J 59:406-415. doi: 10.3349/ymj.2018.59.3.406

Objective: To study the therapeutic effects of human placenta-derived mesenchymal stem cells (pMSCs) in a dementia rat model using either intracerebroventricular (ICV) or intravenous (IV) injections and analyze their mechanisms of therapeutic action.

Summary: ICV and IV injections of pMSCs facilitate the recovery of cholinergic neuronal populations and cognitive behavior. This recovery likely occurs through paracrine effects that resemble microglia function rather than direct differentiation of injected pMSCs into cholinergic neurons.

Usage: Dementia modeling was established by bilateral ventricle infusion of 192 IgG-SAP to lesion cholinergic neurons. 8 μL of 192 IgG-saporin (0.63 μg/μL) were bilaterally injected into the lateral ventricle at a rate of 1 μL/min and was left to diffuse for 5 min after injection. Rats were subjected to the Morris water maze and subsequent immunostaining analyses.

Tata A, Kobayashi Y, Chow RD, Tran J, Desai A, Massri AJ, McCord TJ, Gunn MD, Tata PR (2018) Myoepithelial cells of submucosal glands can function as reserve stem cells to regenerate airways after injury. Cell Stem Cell 22:668-683. doi: 10.1016/j.stem.2018.03.018 PMID: 29656943

Objective: To show that myoepithelial cells (MECs) of the submucosal glands (SMGs) proliferate and migrate to repopulate the airway surface epithelium (SE) in multiple injury models.

Summary: SMG-like cells appear on the SE of extra-and intra-lobular airways of large animal lungs following severe injury. The transcription factor SOX9 is necessary for MEC plasticity in airway regeneration.

Usage: Immunostaining

Objective: To determine the noradrenergic contribution to cognitive and histopathological changes in Alzheimer’s Disease.

Summary: Integrity of ascending noradrenergic inputs to the hippocampus may be required for the regulation of specific aspects of learning and memory and to prevent TDP-43 tissue pathology.

Usage: Anti-DBH-SAP was used at a dose of 0.50 µg dissolved in sterile PBS.
