(Summary) Psoriasis is a chronic T-cell-mediated autoimmune skin disease. Tacrolimus (FK506) is commonly used treatment for psoriasis. However, since the molecular weight of FK506 is more than 500 Da, its skin penetration is limited, so that there is a need to improve the penetrability of FK506 to allow for more effective treatment. To this end, we employed iontophoresis (ItP), which is a physical, intradermal drug delivery technology that relies on the use of weak electric current. Previous findings suggest that activation of cell signaling by the weak electric current applied during ItP may affect the expression of inflammatory cytokines, leading to aggravation of psoriasis. In this study, we analyzed the effect of ItP on the expression of various inflammatory cytokines in the skin, and subsequently examined the therapeutic effect of ItP using negatively-charged liposomes encapsulating FK506 (FK-Lipo) in a rat psoriasis model induced by imiquimod. We found that ItP (0.34 mA/cm, 1 h) did not affect mRNA levels of inflammatory cytokines or epidermis thickness, indicating that ItP is a safe technology for psoriasis treatment. ItP of FK-Lipo suppressed the expression of inflammatory cytokines induced by imiquimod treatment to a greater extent than skin treated with FK506 ointment for 1 h. Furthermore, epidermis thickening was significantly suppressed only by ItP of FK-Lipo. Taken together, results of this study demonstrate the successful development of an efficient treatment for psoriasis by combining FK-Lipo and ItP, without disease aggravation associated with the weak electric current.

(Summary) Vitamin E succinate (VES) is an esterified form of natural α-tocopherol, has turned out to be novel anticancer agent. However, its anticancer mechanisms have not been illustrated. Previously, we reported VES mediated Ca release from the endoplasmic reticulum (ER) causes mitochondrial Ca overload, leading to mitochondrial depolarization and apoptosis. Here, we elucidated the mechanism of VES-induced Ca transfer from ER to mitochondria by investigating the role of VES in ER-mitochondria contact formation. Transmission electron microscopic observation confirms VES mediated ER-mitochondria contact while fluorescence microscopic analysis revealed that VES increased mitochondria-associated ER membrane (MAM) formation. Pre-treatment with the inositol 1,4,5-triphosphate receptor (IPR) antagonist 2-aminoethyl diphenylborinate (2-APB) decreased VES-induced MAM formation, suggesting the involvement of VES-induced Ca efflux from ER in MAM formation. The ER IPR receptor is known to interact with voltage-dependent anion channels (VDAC) via the chaperone glucose-regulated protein 75 kDa (GRP75) to bring ER and mitochondria nearby. Although we revealed that VES treatment does not affect GRP75 protein level, it increases GRP75 localization in the MAM. In addition, the inhibition of Ca release from ER by 2-APB decreases GRP75 localization in the MAM, suggesting the possibility of Ca-induced conformational change of GRP75 that promotes formation of the IPR-GRP75-VDAC complex and thereby encourages MAM formation. This study identifies the mechanism of VES-induced enhanced Ca transfer from ER to mitochondria, which causes mitochondrial Ca overload leading to apoptosis.

Megrab and Kentaro Kogure : The effect of iontophoretic-delivered polyplex vaccine on melanoma regression, Biological & Pharmaceutical Bulletin, Vol.46, No.3, 494-504, 2023. (Summary) Although the strategy in cancer vaccination is to provide a therapeutic effect against an established tumor, there is an urgent need to develop prophylactic vaccines for non-viral cancers. In this study, we prepared polyplex nanoparticles through electrostatic interactions between a positively-charged modified tumor associated antigen, namely human derived melanoma gp100 peptide (KVPRNQDWL-RRRR), and a negatively charged cytosine-phosphate-guanosine motif (CpG-ODN) adjuvant. We previously demonstrated successful transdermal delivery of various hydrophilic macromolecules by iontophoresis (IP) using weak electricity. Herein, we investigated the effectiveness of IP in the transdermal delivery of a prophylactic polyplex vaccine. IP was successful in establishing a homogenous distribution of the vaccine throughout skin. Efficacy of the vaccine was demonstrated against melanoma growth. A significant tumor regression effect was observed, which was confirmed by elevated mRNA expression levels of various cytokines, mainly interferon (IFN)-γ, as well as infiltration of cytotoxic CD8 T cells. Additionally, we evaluated the therapeutic effect of the vaccine and we found a significant reduction in tumor burden. Stimulation of systemic immunity was confirmed by upregulation of IFN-γ. This is the first report to demonstrate the use of IP in the transdermal delivery of a prophylactic melanoma vaccine.

(Summary) α-Tocopheryl succinate (TS), a redox-silent succinyl ester of natural α-Tocopherol, has emerged as a novel anti-cancer agent. However, the underlying mechanism is unclear. We found that the terminal dicarboxylic moiety of tocopheryl esters contributes to apoptosis induction and thus cytotoxicity. To further examine this relationship, we compared the pro-apoptotic activity of TS, which has four carbon atoms in the terminal dicarboxylic moiety, to that of a newly synthesized, tocopheryl glutarate (Tglu), which has five. Cytotoxicity assays in vitro confirmed that TS stimulated apoptosis, while Tglu was non-cytotoxic. In investigating biological mechanisms leading to these opposing effects, we found that TS caused an elevation of intracellular superoxide, but Tglu did not. TS increased intracellular Ca in cultured cells, suggesting induction of endoplasmic reticulum (ER) stress; however, Tglu did not affect Ca homeostasis. 1,4,5-trisphosphate (IP ) receptor antagonist 2-Aminoethyl diphenylborinate (2-APB) decreased TS-induced intracellular Ca , restored mitochondrial activity and cell viability in TS-treated cells, establishing the ER-mitochondria relationship in apoptosis induction. Moreover, real-time PCR, immunostaining and Western blotting assays revealed that TS downregulated glucose-regulated protein 78 (GRP78), which maintains ER homeostasis and promotes cell survival. Conversely, Tglu upregulates GRP78. Taken together, our results suggest a model in which TS-mediated superoxide production and GRP78 inhibition induce ER stress, which elevates intracellular Ca and depolarizes mitochondria, leading to apoptosis. Because Tglu does not affect superoxide generation and increases GRP78 expression, it inhibits ER stress and is thereby non-cytotoxic. Our research provides insight into the structure-activity relationship of tocopheryl esters regarding the induction of apoptosis.

(Summary) Heat is a detrimental environmental stressor that disrupts spermatogenesis and results in male infertility. Previous investigations have shown that heat stress reduces the motility, number, and fertilization ability of living spermatozoa. Sperm hyperactivation, capacitation, acrosomal reaction, and chemotaxis towards the ova are regulated by the cation channel of sperm (CatSper). This sperm-specific ion channel triggers the influx of calcium ions into sperm cells. The aim of this study in rats was to investigate whether heat treatment affected the expression levels of CatSper-1 and -2, together with the sperm parameters, testicular histology and weight. The rats were exposed to heat stress for 6 days and the cauda epididymis and testis were collected 1, 14, and 35 days after heat treatment to measure sperm parameters, gene and protein expression, testicular weight, and histology. Interestingly, we found that heat treatment caused a notable downregulation of CatSper-1 and -2 expression at all three time points. In addition, there were significant reductions in sperm motility and number and an increase in the percentage of abnormal sperm at 1 and 14 days, with cessation of sperm production at 35 days. Furthermore, expression of the steroidogenesis regulator, 3 beta-hydroxysteroid dehydrogenase (3β-HSD) was upregulated in the 1-, 14- and 35-day samples. Heat treatment also upregulated the expression of the apoptosis regulator, BCL2-associated X protein (BAX), decreased testicular weight, and altered testicular histology. Therefore, our data showed for the first time that heat stress downregulated CatSper-1 and -2 in the rat testis, and that this may be a mechanism involved in heat stress-induced impairment of spermatogenesis.

(Summary) Antioxidants are useful for the treatment of oxidative stress mediated liver damage. A naturally occurring antioxidant γ-oryzanol is rapidly hydrolyzed to its active hydrophobic metabolite, ferulic acid, inside the body. Limitations associated with the hydrophobicity of ferulic acid can be overcome by encapsulating in a liposomal formulation. As intravenously administered nanoparticles (including liposomes) can effectively reach the liver, such systems may be suitable drug delivery carriers to treat liver injury. In this study, we prepared a liposomal formulation of ferulic acid (ferulic-lipo) and examined its effects on liver damage induced by CCl. Ferulic-lipo were ~100 nm in size and drug encapsulation efficiency was about 92%. Ferulic-lipo showed potent scavenging efficacy against hydroxyl radical compared to α-tocopherol liposomes. Ferulic-lipo significantly prevented CCl-mediated cytotoxicity in human hepatocarcinoma cells. Furthermore, intravenous administration of ferulic-lipo significantly reduced alanine aminotransferase and aspartate amino transferase levels in a rat model of liver injury. CCl-mediated reactive oxygen species generation in liver was also reduced by intravenous administration of ferulic-lipo. Hepatoprotective effects of ferulic-lipo were demonstrated by histological observation of CCl-induced liver tissue damage. Therefore, ferulic-lipo exhibit potent antioxidative capacity and were suggested to be an effective formulation for prevention of oxidative damage of liver tissue.

(Summary) Delivery of cerebroprotective agents using liposomes has been demonstrated to be useful for treating cerebral ischemia/reperfusion (I/R) injury. We previously reported that intravenous administration of liposomes with diameters of 100 nm showed higher accumulation in the I/R region compared with larger liposomes (>200 nm) by passage through the disintegrated blood-brain barrier, suggesting a size-dependence for liposome-mediated drug delivery. Based on these findings, we hypothesized that regulation of liposomal particle size (<100 nm) may enhance the therapeutic efficacy of encapsulated drugs on cerebral I/R injury. Herein, we prepared lipid nanoparticles (LNP) with particle sizes <100 nm by the microfluidics method and compared their therapeutic potential with LNP exhibiting sizes >100 nm in cerebral I/R model rats. Intravenously administered smaller LNP (ca. 60 nm) exhibited wider accumulation and diffusivity in the brain parenchyma of the I/R region compared with larger LNP (>100 nm). Importantly, treatment with LNP encapsulating the cerebroprotective agent FK506 (FK-LNP) with particle sizes <100 nm showed greater cerebroprotective effects than FK-LNP with sizes >100 nm, and also significantly ameliorated brain injury. These results suggest that particle size regulation of LNP to sizes <100 nm can enhance the therapeutic effect of encapsulated drugs for treatment of cerebral I/R injury, and that FK-LNP could be a promising cerebroprotective agent.

(Summary) Modification with antibodies is a useful strategy for the delivery of nanoparticles to target cells. However, the complexity of the required chemical modifications makes them time-consuming and low efficiency, and the orientation of the antibody is challenging to control. To develop a simple, fast, effective, and orientation-controllable technology, we employed staphylococcal protein A, which can bind to the Fc region of antibodies, as a tool for conjugating antibodies to nanoparticles. Specifically, we modified the C-domain dimer of protein A to contain a lysine cluster to create a molecule, DPACK, that would electrostatically bind to anionic liposomes. Using this protein, antibody-modified liposomes can be prepared in 35 min with two steps: (1) interaction of DPACK with liposomes and (2) interaction of an antibody with DPACK-modified liposomes. Binding efficiencies of DPACK with liposomes and IgG with DPACK-modified liposomes were 75% and 72-84%, respectively. Uptake of liposomes modified with anti-epidermal growth factor receptor (EGFR) antibodies via DPACK by EGFR-expressing cancer cells was significantly higher than that of unmodified liposomes, and the liposomes accumulated in tumors and colocalized with EGFR. This simple, fast, effective and orientation-controllable technology for preparing antibody-modified liposomes will be useful for active targeting drug delivery.
