Abstract
Currently, one of the most significant and rapidly growing unmet medical challenges is the treatment of neurodegenerative diseases such as Alzheimer's disease (AD) and Parkinson's disease (PD). This challenge encompasses the imperative development of efficacious therapeutic agents and overcoming the intricacies of the blood-brain barrier for successful drug delivery. Here we focus on the delivery aspect with particular emphasis on cell-penetrating peptides (CPPs), widely used in basic and translational research as they enhance drug delivery to challenging targets such as tissue and cellular compartments and thus increase therapeutic efficacy. The combination of CPPs with nanomaterials such as nanoparticles (NPs) improves the performance, accuracy, and stability of drug delivery and enables higher drug loads. Our review presents and discusses research that utilizes CPPs, either alone or in conjugation with NPs, to mitigate the pathogenic effects of neurodegenerative diseases with particular reference to AD and PD.

Abstract
Heat Shock Factor 1 (HSF1) is the master regulator of the heat shock response, a universal survival mechanism throughout eukaryotic species used to buffer potentially lethal proteotoxic conditions. HSF1's function in vivo is regulated by several factors, including post translational modifications and elevated temperatures, whereupon it forms trimers to bind with heat shock elements in DNA. Unsurprisingly, HSF1 is also extremely sensitive to elevated temperatures in vitro, which poses specific technical challenges when producing HSF1 using a recombinant expression system. Although there are several useful publications which outline steps taken for HSF1 expression and purification, studies that describe specific strategies and detailed protocols to overcome HSF1 trimerisation and degradation are currently lacking. Herein, we have reported our detailed experimental protocol for the expression and purification of monomeric human HSF1 (HsHSF1) as a major species. We also propose a refined method of inducing HsHSF1 activation in vitro, that we consider more accurately mimics HsHSF1 activation in vivo and is therefore more physiologically relevant.

Abstract
Parkinson disease, a progressive neurodegenerative disorder, is caused by the pathological accumulation of proteins, including the ubiquitous presynaptic protein α-synuclein. Alterations in the metabolism of α-synuclein have clearly been linked to neurodegeneration, and early steps in the pathological sequence of this protein include the formation of oligomers, fibrils, and small aggregates. Targeting these early steps of oligomerization is one of the main therapeutic approaches in the quest to develop disease-modifying agents. Molecular chaperones, molecules that can mediate the proper folding and refolding of client proteins, are vital to cell function and survival and thus have been explored as potential therapeutic agents. Important to Parkinson disease, chaperones are capable of preventing α-synuclein misfolding, oligomerization, and aggregate formation as shown in vitro and in Parkinson disease animal models. Furthermore, chaperones and associated co-chaperones are closely linked to pathways of protein degradation, like the ubiquitin-proteasome system and autophagy, and are thus able to remove irreversibly misfolded proteins. In this review, we summarize the role of molecular chaperones in Parkinson disease models and discuss the importance of preserving protein homeostasis to prevent neurodegeneration. We also review the growing number of exciting studies that have targeted molecular chaperone function as a novel therapeutic approach.

Abstract
The distal cytoplasmic motifs of leukemia inhibitory factor receptor α-chain (LIFRα-CT3) can independently induce intracellular myeloid differentiation in acute myeloid leukemia (AML) cells by gene transfection; however, there are significant limitations in the potential clinical use of these motifs due to liposome-derived genetic modifications. To produce a potentially therapeutic LIFRα-CT3 with cell-permeable activity, we constructed a eukaryotic expression pcDNA3.0-TAT-CT3-cMyc plasmid with a signal peptide (ss) inserted into the N-terminal that codes for an ss-TAT-CT3-cMyc fusion protein. The stable transfection of Chinese hamster ovary (CHO) cells via this vector and subsequent selection by Geneticin resulted in cell lines that express and secrete TAT-CT3-cMyc. The spent medium of pcDNA3.0-TAT-CT3-cMyc-transfected CHO cells could be purified using a cMyc-epitope-tag agarose affinity chromatography column and could be detected via SDS-PAGE, with antibodies against cMyc-tag. The direct administration of TAT-CT3-cMyc to HL-60 cell culture media caused the enrichment of CT3-cMyc in the cytoplasm and nucleus within 30 min and led to a significant reduction of viable cells (P < 0.05) 8 h after exposure. The advantages of using this mammalian expression system include the ease of generating TAT fusion proteins that are adequately transcripted and the potential for a sustained production of such proteins in vitro for future AML therapy.

Abstract
Parkinson's disease is a neurodegenerative movement disorder that is caused, in part, by the loss of dopaminergic neurons within the substantia nigra pars compacta of the basal ganglia. The presence of intracellular protein aggregates, known as Lewy bodies and Lewy neurites, within the surviving nigral neurons is the defining neuropathological feature of the disease. Accordingly, the identification of specific genes mutated in families with Parkinson's disease and of genetic susceptibility variants for idiopathic Parkinson's disease has implicated abnormalities in proteostasis, or the handling and elimination of misfolded proteins, in the pathogenesis of this neurodegenerative disorder. Protein folding and the refolding of misfolded proteins are regulated by a network of interactive molecules, known as the chaperone system, which is composed of molecular chaperones and co-chaperones. The chaperone system is intimately associated with the ubiquitin-proteasome system and the autophagy-lysosomal pathway which are responsible for elimination of misfolded proteins and protein quality control. In addition to their role in proteostasis, some chaperone molecules are involved in the regulation of cell death pathways. Here we review the role of the molecular chaperones Hsp70 and Hsp90, and the cochaperones Hsp40, BAG family members such as BAG5, CHIP and Hip in modulating neuronal death with a focus on dopaminergic neurodegeneration in Parkinson's disease. We also review current progress in preclinical studies aimed at targetting the chaperone system to prevent neurodegeneration. Finally, we discuss potential future chaperone-based therapeutics for the symptomatic treatment and possible disease modification of Parkinson's disease.
