velopmental outcomes. Moreover, the heightened stress responses in late gestation and concomitant dampened inflammatory response to allergic asthma suggest that interactions between the maternal immune and stress-response systems shape early life fetal programming.Neuropathic pain is a major symptom of multiple sclerosis (MS) with up to 92% of patients reporting bodily pain, and 85% reporting pain severe enough to cause functional disability. None of the available therapeutics target MS pain. Toll-like receptors 2 and 4 (TLR2/TLR4) have emerged as targets for treating a wide array of autoimmune disorders, including MS, as well as having demonstrated success at suppressing pain in diverse animal models. The current series of studies tested systemic TLR2/TLR4 antagonists in males and females in a low-dose Myelin oligodendrocyte glycoprotein (MOG) experimental autoimmune encephalomyelitis (EAE) model, with reduced motor dysfunction to allow unconfounded testing of allodynia through 50+ days post-MOG. The data demonstrated that blocking TLR2/TLR4 suppressed EAE-related pain, equally in males and females; upregulation of dorsal spinal cord proinflammatory gene expression for TLR2, TLR4, NLRP3, interleukin-1β, IkBα, TNF-α and interleukin-17; and upregulation of dorsal spinal cord expression of glial immunoreactivity markers. In support of these results, intrathecal interleukin-1 receptor antagonist reversed EAE-induced allodynia, both early and late after EAE induction. In contrast, blocking TLR2/TLR4 did not suppress EAE-induced motor disturbances induced by a higher MOG dose. These data suggest that blocking TLR2/TLR4 prevents the production of proinflammatory factors involved in low dose EAE pathology. Moreover, in this EAE model, TLR2/TLR4 antagonists were highly effective in reducing pain, whereas motor impairment, as seen in high dose MOG EAE, is not affected.The current health crisis of corona virus disease 2019 (COVID-19) highlights the urgent need for vaccine systems that can generate potent and protective immune responses. Protein vaccines are safe, but conventional approaches for protein-based vaccines often fail to elicit potent and long-lasting immune responses. Nanoparticle vaccines designed to co-deliver protein antigens and adjuvants can promote their delivery to antigen-presenting cells and improve immunogenicity. However, it remains challenging to develop vaccine nanoparticles that can preserve and present conformational epitopes of protein antigens for induction of neutralizing antibody responses. Here, we have designed a new lipid-based nanoparticle vaccine platform (NVP) that presents viral proteins (HIV-1 and SARS-CoV-2 antigens) in a conformational manner for induction of antigen-specific antibody responses. We show that NVP was readily taken up by dendritic cells (DCs) and promoted DC maturation and antigen presentation. NVP loaded with BG505.SOSIP.664 (SOSIP) or SARS-CoV-2 receptor-binding domain (RBD) was readily recognized by neutralizing antibodies, indicating the conformational display of antigens on the surfaces of NVP. Rabbits immunized with SOSIP-NVP elicited strong neutralizing antibody responses against HIV-1. Furthermore, mice immunized with RBD-NVP induced robust and long-lasting antibody responses against RBD from SARS-CoV-2. These results suggest that NVP is a promising platform technology for vaccination against infectious pathogens.It is still a challenge to develop gene replacement therapy for retinal disorders caused by mutations in large genes, such as Stargardt disease (STGD). STGD is caused by mutations in ABCA4 gene. Previously, we have developed an effective non-viral gene therapy using self-assembled nanoparticles of a multifunctional pH-sensitive amino lipid ECO and a therapeutic ABCA4 plasmid containing rhodopsin promoter (pRHO-ABCA4). In this study, we modified the ABCA4 plasmid with simian virus 40 enhancer (SV40, pRHO-ABCA4-SV40) for enhanced gene expression. We also prepared and assessed the formulations of ECO/pDNA nanoparticles using sucrose or sorbitol as a stablilizer to develop consistent and stable formulations. Results demonstrated that ECO formed stable nanoparticles with pRHO-ABCA4-SV40 in the presence of sucrose, but not with sorbitol. The transfection efficiency in vitro increased significantly after introduction of SV40 enhancer for plasmid pCMV-ABCA4-SV40 with a CMV promoter. Sucrose didn't affect the transfection efficiency, while sorbitol resulted in a fluctuation of the in vitro transfection efficiency. Subretinal gene therapy in Abca4-/- mice using ECO/pRHO-ABCA4 and ECO/pRHO-ABCA4-SV40 nanoparticles induced 36% and 29% reduction in A2E accumulation respectively. Therefore, the ECO/pABCA4 based nanoparticles are promising for non-viral gene therapy for Stargardt disease and can be expended for applications in a variety of visual dystrophies with mutated large genes.The era of Nanomedicine has arrived with the approval of ONPATTRO™ by the FDA in 2018. Lipid nanoparticle (LNP) technology has succeeded in delivering siRNA to the human liver in genetic diseases and has also been applied to mRNA vaccinations for COVID-19 using a similar LNP technology. In this review, we focus on the current status of new lipids for use in LNP formulations including our original lipids (CL4H6/CL4C6/CL4D6) as well as mechanisms of targeting without a ligand. Clinical applications of nano DDS are moving forward rapidly in the field of cancer immunology since the successful introduction of OPDIVO™ in 2014. Antigen presentation and the maturation of immune cells can be controlled by nano DDS for cancer immunotherapy. YSK12-C4, a newly designed ionizable amino lipid can induce successful immune activation by silencing mRNA in DC and NK cells, which are expected to be evaluated for clinical use. Finally, new cancer therapy by targeting mitochondria involving the use of a MITO-Porter, a membrane fusion-type mitochondrial delivery system, has been introduced. The importance of delivering a photo sensitizer to mitochondria was clearly demonstrated in photodynamic cancer therapy. Clinical applications of MITO-Porters started in collaborative efforts with LUCA Science Co., Ltd. And was established in 2018. find more The future direction of Nanomedicine is discussed.
