Summary: To test the role of IL-1 receptor brain macrophages, the work of Chaskiel et al. employed IL-1 coupled to the ribosome toxin, saporin, and administered this conjugate into forebrain ventricles to effectively reduce the number of CD163-positive perivascular macrophages with no reduction of food intake after subsequent IL-1beta administration.

Objective: To study nociplastic pain the authors developed a murine model in which postinjury thermal stimulation of injured area triggers the transition to a nociplastic pain state more readily in females.

Summary: Postinjury stimulation of an injured area triggers the transition from transient pain to nociplastic pain, females are more susceptible to this transition, and allyl isothiocyanate -sensitive afferents at the previously injured area maintain the nociplastic pain state in a female gonadal hormone-dependent manner.

Usage: Intrathecal injection of Mac-1-SAP (IT-06) 8.85 mM in mice.

Objective: To investigate the mechanisms of brain-derived neurotrophic factor (BDNF) in the inner ear, by analyzing the expression of mature BDNF (mBDNF), its proform proBDNF and their respective receptors the low affinity p75 neurotrophin receptor (p75NTR) and the neurotrophic receptor tyrosine kinase 2 (NTRK2).

Summary: Treatment with proBDNF is not toxic for spiral ganglion neuron (SGN) survival but simultaneously not protective. However, combined treatment of mBDNF and proBDNF maintained and perhaps slightly increased the protective effect of mBDNF.

Exp Neurol 347:113892. doi: 10.1016/j.expneurol.2021.113892

Objective: To determine the effect of ketoprofen delivery on enhanced phrenic long-term facilitation (pLTF)

Summary: pLTF was surprisingly attenuated in 7d CTB-SAP rats and enhanced in 28d CTB-SAP rats (both p < 0.05) following ketoprofen delivery.

Usage: Rats received bilateral intrapleural injections of CTB-SAP; 25 μg dissolved in PBS.

Objective: To test two mouse lung organoid mechanotransductive models to address deficiencies in cell culture models.

Summary: Cyclic stretch increased TGF-β and integrin-mediated signaling, with upstream analysis indicating roles for histone deacetylases, microRNAs, and long noncoding RNAs.

Summary: This PhD dissertation to determine the mechanism behind BDNF-mediated cardiovascular regulation.

Usage: Rats received bilateral NTS injections of vehicle or Anti-DBH-SAP, which selectively lesions catecholaminergic neurons. Treatment increased blood pressure in the GFP group but failed to affect blood pressure in the BDNF group.

Objective: To demonstrate that biotinylated anti-CD45-SAP or anti-cKit-SAP mixed with Streptavidin-Saporin along with Janus kinase 1/2, enables alloengraftment on murine allo-hematopoietic stem cell transplantation (HSCT) models.

Summary: HSCT has therapeutic potential. However, the transplantation requires first depletion and secondly, for allogeneic-HCST, host and immune responses need to be controlled to prevent graft rejection. The allo-HSCT conditioning strategy exemplifies the promise of immunotherapy to improve the safety of HSCT for treating hematologic diseases.

Usage: Antibodies were incubated with Streptavidin-ZAP (1:1 molar ratio) for 15 minutes at 20°C and . The doses of CD45.2 and cKit conjugates were injected retroorbitally (41.8 μg and 33.2 μg, respectively).

Brain Res 1773:147705. doi: 10.1016/j.brainres.2021.147705 PMID: 34744015

Objective: To investigate the effects of Oxytocin-SAP in the substantia nigra of male rats, and assess its impact on nigral Tyrosine Hydroxylase-immunoreactivity, dopamine content, locomotor activity, rotational turning, and striatal dopamine function.

Summary: Researchers investigated the effects of injecting oxytocin-conjugated Saporin into the substantia nigra of male rats. They found that this treatment led to changes in the activity of the nigrostriatal dopaminergic system, as evidenced by alterations in behavior and neurochemical markers associated with dopamine function.

Usage: Oxytocin-SAP (60 ng/μl and 120 ng/μl) was injected unilaterally into the substantia nigra of male rats, respectively, compared to Blank-SAP.
