Recent work has stimulated interest in the use of exosomes as nanocarriers for delivery of small drugs, RNAs, and proteins to the central nervous system (CNS). To overcome the blood-brain barrier (BBB), exosomes were modified with brain homing peptides that target brain endothelium but likely to increase immune response. Here for the first time we demonstrate that there is no need for such modification to penetrate the BBB in mammals. The naïve macrophage (Mϕ) exosomes can utilize, 1) on the one hand, the integrin lymphocyte function-associated antigen 1 (LFA-1) and intercellular adhesion molecule 1 (ICAM-1), and, 2) on the other hand, the carbohydrate-binding C-type lectin receptors, to interact with brain microvessel endothelial cells comprising the BBB...

Protein phosphorylation, mediated by protein kinases, has important physiological and pathological implications in our lives . Targeting kinase is one of the most interesting of the emerging topics in the pharmaceutical industry, especially since there is a focus on cancer therapy. Given that kinases may be involved in the aging process the focus will be on using the kinase inhibitor for anti-aging intervention to enhance healthspan and increase longevity. In this review , we will summarize: (i) the impact of the phosphoproteomic approach to elucidate molecular mechanisms of diseases; (ii) importance of the drug discovery approach for targeting kinases; (iii) the dysregulation of Janus kinase (JAK) / signal-transducing adapter molecules (STAT) and p70 ribosomal protein S6 kinase (S6Ks) pathway in aging and the age-related process; (iv) the epidemiological studies available in order to see whether a correlation between JAK/STAT and S6Ks mRNA expression levels exist in cancer and in patient outcome; (v) finally, we will show selected inhibitors of these kinases approved by the US Food and Drug Administration (FDA)...

Two-component systems in Acinetobacter baumannii are associated with its virulence, drug resistance, motility, biofilm formation, and other characteristics. In this study, we used RecAb , a genetic engineering method, to investigate the function of A1S_2811 in A. baumannii strain ATCC17978. A1S_2811, a hypothetical hybrid sensor histidine kinase/response regulator, has four histidine-containing phosphotransfer domains, a CheA-like regulatory domain, and a CheY-like receiver domain at its C terminus. Compared with the ATCC17978 strain, both surface motility and biofilm formation at the gas-liquid interface decreased significantly in the A1S_2811 knock-out strain...

WHAT IS KNOWN AND OBJECTIVE: Amiodarone, a commonly used class III antiarrhythmic agent notable for a relatively long half-life of up to 6 months and its pronounced adverse effect profile, is used for both acute and chronic management of cardiac arrhythmias. Chronic use of amiodarone has been associated with asymptomatic hepatotoxicity; however, acute toxicity is thought to be uncommon. There are only six reported cases of acute liver failure (ALF) secondary to amiodarone. In all these cases the outcome of death during the same hospitalization resulted...

BACKGROUND: The neuropeptide transmitter nociceptin, which binds to the nociceptin/orphanin FQ peptide (NOP) receptor, is a core component of the brain's antistress system. Nociceptin exerts its antistress effect by counteracting the functions of corticotropin-releasing factor, the primary stress-mediating neuropeptide in the brain. Basic investigations support a role for medications that target nociceptin receptors in the treatment of alcohol use disorders. Thus, it is of high interest to measure the in vivo status of NOP receptors in individuals with alcohol use disorders...

Monoclonal antibody-based therapeutic agents (antibody drugs) have attracted considerable attention as a new type of drug. Concomitantly, the use of quantitative approaches for characterizing antibody drugs, such as liquid chromatography (LC)-mass spectrometry (MS), has increased. Generally, selective quantification of antibody drugs is done using unique peptides from variable regions (V H and V L) as surrogate peptides. Further, numerous internal standards (ISs) such as stable isotope-labeled (SIL)-intact proteins and SIL-surrogate peptides are used...

Vanadium compounds are promising anti-diabetic agents. However, reducing the metal toxicity while keeping/improving the hypoglycemic effect is still a big challenge towards the success of anti-diabetic vanadium drugs. To improve the therapeutic potency using the anti-oxidative strategy, we synthesized new N,N-dimethylphenylenediamine (DMPD)-derivatized nitrilotriacetic acid vanadyl complexes ([VO(dmada)]). The in vitro biological evaluations revealed that the DMPD-derivatized complexes showed improved antioxidant capacity and lowered cytotoxicity on HK-2 cells than bis(maltolato)oxidovanadium (IV) (BMOV)...
