Despite recent leaps in modern medicine, progress the treatment of neurological diseases remains slow. The near impermeable blood-brain barrier (BBB) that prevents entry therapeutics into brain, and complexity processes, limits specificity potential therapeutics. Moreover, a lack etiological understanding irreversible nature conditions have resulted low tolerability high failure rates towards existing small molecule-based treatments. Neuropeptides, which are proteinaceous molecules produced by body, either nervous system or peripheral organs, modulate function. Although peptide-based originated from metabolic 1920s, adoption development peptide drugs for relatively recent. In this review, we examine natural roles neuropeptides modulation function disorders.

The blood-brain barrier (BBB) is the most specialized biological in body. This configuration of cells protects brain from invasion molecules and particles through formation tight junctions. To learn more about transport to brain, vitro modeling BBB continuously advanced. types models selected vary with goal each individual study, but same validation methods, quantification junctions, permeability assays are often used. With Transwells microfluidic devices, information regarding has been observed. Disease have developed examine effects on integrity. not only understand normal physiology, also create treatments for diseases. review will highlight several recent studies show diversity model selection many applications research.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continues to be a world-wide pandemic with overwhelming socioeconomic impact. Since inflammation is one of the major causes COVID-19 complications, associated molecular mechanisms have been focus many studies better understand this and develop improved treatments for patients contracting SARS-CoV-2. Among these, strong emphasis has placed on pro-inflammatory cytokines, associating severity so-called "cytokine storm." More recently, peptide bradykinin, its dysregulated signaling or "bradykinin storm," emerged as primary mechanism explain COVID-19-related complications. Unfortunately, important development may not fully capture main players that underlie severity. To end, in focused review, several lines evidence are provided suggest addition two closely related vasoactive peptides, substance P neurotensin, also likely drive microvascular permeability inflammation, responsible pathology. Furthermore, based published experimental observations, it postulated ACE neprilysin, peptidase neurolysin (Nln) contribute accumulation progression disease. In conclusion, proposed "vasoactive storm" simultaneous inhibition all three peptidergic systems could therapeutically more advantageous rather than modulation any single alone.

Stroke is a neurological disorder with high disability and mortality rates. Almost 80% of stroke cases are ischemic stroke, the remaining hemorrhagic stroke. The only approved treatment for thrombolysis and/or thrombectomy. However, these treatments cannot sufficiently relieve disease outcome, many patients remain disabled even after effective thrombolysis. Therefore, rehabilitative therapies necessary to induce remodeling in brain. Currently, stem cell transplantation, especially via use induced pluripotent cells (iPSCs), considered promising alternative therapy stimulating neurogenesis brain remodeling. iPSCs generated from somatic by specific transcription factors. biological functions similar those embryonic (ESCs), including immunomodulation, reduced cerebral blood flow, edema, autophagy. Although iPSC plays role both its application associated certain limitations. Tumor formation, immune rejection, survival, migration some concerns therapy. cell-free as an method can overcome This study reviews therapeutic models underlying mechanisms constraints cells. Moreover, using exosomes, apoptotic bodies, microvesicles discussed.

Peptidase neurolysin (Nln) is an enzyme that functions to cleave various neuropeptides. Upregulation of Nln after stroke has identified the as a critical endogenous cerebroprotective mechanism and validated target for treatment ischemic stroke. Overexpression in mouse model results dramatic improvement outcomes, while pharmacological inhibition aggravates them. Activation therefore emerged intriguing drug discovery efforts Herein, we report hit-to-lead optimization first-in-class activators based on histidine-containing dipeptide hits from virtual screen. Adopting peptidomimetic approach provided lead compounds retain pharmacophoric histidine moiety possess single-digit micromolar potency over 40-fold greater than hit scaffolds. These exhibit 5-fold increased brain penetration, significant selectivity highly homologous peptidases, 65-fold increase stability, 'drug-like' fraction unbound brain.

Neurolysin (Nln) is a recently recognized endogenous mechanism functioning to preserve the brain from ischemic injury. To further understand pathophysiological function of this peptidase in stroke and other neurologic disorders, present study was designed identify small molecule activators Nln. Using computational approach, structure Nln explored, which followed by docking silico screening ∼140,000 molecules National Cancer Institute Developmental Therapeutics Program database. Top ranking compounds were evaluated an enzymatic assay, two hit histidine-dipeptides studied detail. The identified dipeptides enhanced rate synthetic substrate hydrolysis recombinant (human rat) mouse brain–purified concentration-dependent manner (micromolar A50 Amax ≥ 300%) but had negligible effect on activity closely related peptidases. Both also substrates neurotensin, angiotensin I, bradykinin increased efficiency (Vmax/Km ratio) manner. competitive inhibitor dynorphin A (1-13) did not affect each other's affinity for Nln, suggesting differing nature their respective binding sites. Lastly, drug responsive target stability (DARTS) differential scanning fluorimetry (DSF) assays confirmed interaction with activator molecule.
