Abstract
Vaccination is the most cost-effective method for preventing various infectious diseases. Compared with conventional vaccines, new-generation vaccines, especially recombinant protein or synthetic peptide vaccines, are safer but less immunogenic than crude inactivated microbial vaccines. The immunogenicity of these vaccines can be enhanced using suitable adjuvants. This is the main reason why adjuvants are of great importance in vaccine development. Several novel human emulsion-based vaccine adjuvants (MF59, AS03) have been approved for clinical use. This paper reviews the research progress on emulsion-based adjuvants and focuses on their mechanism of action. An outlook can be provided for the development of emulsion-based vaccine adjuvants.

Peptide-based vaccine targeting IL17A attenuates experimental spondyloarthritis in HLA-B27 transgenic rats. RMD Open 2023; 9:rmdopen-2022-002851.

Abstract
OBJECTIVES Spondyloarthritis (SpA) is known as series of immune-mediated inflammatory disease of the axial and peripheral joints. Human leucocyte antigen (HLA)-B27 is a genetic risk factor for SpA. Recent evidence suggests that the interleukin -17 (IL17) axis strongly contributes to SpA. This study aimed to assess the efficacy of an IL17A peptide-based vaccine on SpA manifestations in model rats. METHODS HLA-B27/human β2-microglobulin (hβ2M) transgenic rats were immunised with heat-inactivated Mycobacterium tuberculosis (MT) to develop spondylitis and arthritis as an experimental SpA model after immunisation with a keyhole limpet hemocyanin-conjugated IL17A peptide-based vaccine with an alum adjuvant three times. The IL17A antibody titre was assessed using ELISA, and arthritis score and joint thickness were monitored two times a week. Enzyme-linked immunospot (ELISpot) assays for IL4- and interferon-γ-secreting splenocytes were conducted to evaluate IL17A-specific T cell activation. We also evaluated the effect of IL17A vaccine in SpA therapeutic model. RESULTS The IL17A peptide-based vaccine with alum adjuvant successfully induced antibody production and suppressed the arthritis score and joint thickness. X-ray and histological analyses showed that enthesitis, bone destruction and new bone formation were inhibited by the IL17A vaccine. The ELISpot assay showed that the IL17A peptide-based vaccine did not elicit any IL17A-reactive T cell responses. IL17A vaccine tends to mitigate, but not significant, in SpA treatment model. These data showed that the peptide-based vaccine targeting IL17A alleviated the SpA phenotype in a heat-inactivated MT-induced SpA model in HLA-B27/hβ2M transgenic rats. CONCLUSIONS IL17A peptide-based vaccine may be a therapeutic option for SpA treatment.

Brain Res 2021; 1772:147667. [PMID: 34587500 DOI: 10.1016/j.brainres.2021.147667] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 09/15/2021] [Accepted: 09/21/2021] [Indexed: 12/11/2022]
Abstract
INTRODUCTION As several clinical trials have revealed that angiotensin-converting enzyme inhibitors and angiotensin II (Ang II) receptor blockers may be efficient in treating vascular dementia (VaD), the long-acting blockade of the renin-angiotensin system (RAS) would be useful considering the poor adherence of antihypertensive drugs. Accordingly, we continuously blocked RAS via vaccination and examined the effectiveness of the VaD model in rats. METHODS Male Wistar rats were exposed to two-vessel occlusions (2VO) after three injections of Ang II peptide vaccine. The effects of the vaccine were evaluated in the novel object recognition test, brain RAS components, and markers for oligodendrocytes. RESULTS In the vaccinated rats, anti-Ang II antibody titer level was increased in serum until Day 168, but not in cerebral parenchyma. Vaccinated rats showed better object recognition memory with inhibited demyelination in the corpus callosum and activation of astrocytes and microglia. Also, levels of BrdU/GSTπ-positive cells and the phosphorylation of cAMP response element binding protein was increased in vaccinated rats, indicating that the differentiation of oligodendrocyte progenitor cells to mature oligodendrocytes was accelerated. Vaccinated rats showed increased expression of fibroblast growth factor-2 (FGF2), which was observed in endothelial cells. Angiotensinogen mRNA was decreased at 7 days after 2VO but increased at 14 and 28 days. CONCLUSION Ang II vaccine might have promoted oligodendrocyte differentiation and inhibited astrocytic and microglial activation by stimulating FGF2 signaling in the endothelial cells-oligodendrocyte/astrocyte/microglia coupling. These data indicate the feasibility of Ang II vaccine for preventing progression of vascular dementia.

Abstract
While oral agents have been the gold standard for cardiovascular disease therapy, the new generation of treatments is switching to other administration options that offer reduced dosing frequency and more efficacy. The lymphatic network is a unidirectional and low-pressure vascular system that is responsible for the absorption of interstitial fluids, molecules, and cells from the peripheral tissue, including the skin and the intestines. Targeting the lymphatic route for drug delivery employing traditional or new technologies and drug formulations is exponentially gaining attention in the quest to avoid the hepatic first-pass effect. The present review will give an overview of the current knowledge on the involvement of the lymphatic vessels in drug delivery in the context of cardiovascular disease.

Abstract
Targeting angiotensinogen (AGT) may provide a novel approach to more optimally inhibit the renin-angiotensin-aldosterone system pathway. Double-blind, placebo-controlled clinical trials were performed in subjects with hypertension as monotherapy or as an add-on to angiotensin-converting enzyme inhibitors/angiotensin receptor blockers with IONIS-AGT-LRx versus placebo up to 2 months. IONIS-AGT-LRx was well tolerated with no significant changes in platelet count, potassium levels, or liver and renal function. IONIS-AGT-LRx significantly reduced AGT levels compared with placebo in all 3 studies. Although not powered for this endpoint, trends were noted in blood pressure reduction. In conclusion, IONIS-AGT-LRx significantly reduces AGT with a favorable safety, tolerability, and on-target profile.

Abstract
OBJECTIVES We recently developed a novel peptide, AJP001, that possesses both a mouse T-cell epitope and adjuvant action. Direct conjugation to the antigen is useful for peptide vaccines without the addition of adjuvants. In this study, the efficacy of an angiotensin (Ang) II and AJP001-conjugated peptide vaccine (AJ-Ang II) was evaluated in mice. METHODS The anti-Ang II antibody titer was measured in Balb/C mice following three injections of AJ-Ang II at 2-week intervals. SBP was measured during vaccination of Balb/C mice treated with Ang II infusion (1 μg/kg per min). RESULTS AJ-Ang II treatment resulted in an increase in the anti-Ang II antibody titer in a dose-dependent manner without the addition of adjuvants. In the analysis of the humoral immune response, AJ-Ang II mainly elicited IgG1 antibodies and IL-4 and IL-10 production, as measured by an enzyme-linked immune absorbent spot assay, which suggests the induction of a Th2 response. Importantly, cotreatment with purified antibodies attenuated Ang II-induced extracellular signal-regulated kinase phosphorylation and nuclear factor (NF)-κB activation in cultured vascular smooth muscle cells. The SBP in immunized mice was significantly lower than that in nonimmunized mice (135.9 ± 8.5 vs. 154.9 ± 16.8 mmHg, P = 0.02). Furthermore, Ang II-induced perivascular fibrosis in the heart was significantly attenuated in immunized mice, which also exhibited decreased mRNA expression of collagen I/III and transforming growth factor-β. CONCLUSION AJ-Ang II may be a simple and useful therapeutic peptide vaccine without the addition of any adjuvants.

Abstract
Hypertension is one of the most prevalent cardiovascular diseases worldwide. However, in the population of resistant hypertension, blood pressure is difficult to control effectively. Moreover, antihypertensive drugs may have adverse effect currently. Hence, new therapeutic targets and treatments are needed to uncovered and exploited to control hypertension and its comorbidities. In the past, classical drug targets, such as the aldosterone receptor, aldosterone synthase, and ACE2/angiotensin 1-7/Mas receptor axis, have been investigated. Recently, vaccines and drugs targeting the gastrointestinal microbiome, which represent drug classes, have also been investigated for the management of blood pressure. In this review, we summarized current knowledge on classical and new drug targets and discussed the potential utility of new drugs in the treatment of hypertension.

Abstract
Hypertension remains a leading risk factor for cardiovascular mortality and morbidity globally despite the availability of effective and well-tolerated antihypertensive medications. Accumulating evidence suggests a more aggressive blood pressure regulation aimed at lower targets, particularly for selected patient groups. Our concepts of the optimal method for blood pressure measurement have radically changed, maintaining appropriate standard office measurements for initial assessment but relying on out-of-office measurement to better guide our decisions. Thorough risk stratification provides guidance in decision making; however, an individualized approach is highly recommended to prevent overtreatment. Undertreatment, on the other hand, remains a major concern and is mainly attributed to poor adherence and resistant or difficult-to-control forms of the disease. This review aims to present modern perspectives, novel treatment options, including innovative technological applications and developing interventional and pharmaceutical therapies, and the major concerns emerging from several years of research and epidemiological observations related to hypertension management.

Abstract
Even though effective drugs for treating hypertension are available, a great percentage of patients have inadequate control of their blood pressure. Unwanted side effects and inappropriate oral drug adherence are important factors that contribute to the global problem of uncontrolled hypertension. Vaccination could provide a revolutionary therapy with long-lasting effects, increasing patient compliance and therefore better control of high blood pressure. Nowadays, current immunization approaches against hypertension target renin, angiotensin I, angiotensin II, and angiotensin II type 1 receptor, key elements of the renin–angiotensin system. This article reviews the different vaccination attempts with proteins and peptides against the different molecules of the renin–angiotensin system in the last two decades, safety issues, and other novel prospects biomarkers in hypertension, and summarizes the potential of this immunomodulatory approach in clinical practice.

Abstract
Vaccines are well-known therapies for infectious disease and cancer; however, recently, we and others have developed vaccines for other chronic diseases, such as hypertension, diabetes and dyslipidemia. Although we have many treatment options for hypertension, including angiotensin II type 1 receptor blockers, calcium-channel blockers, and diuretics, a substantial portion of the hypertensive population has uncontrolled blood pressure due to poor medication adherence. When these vaccines are established in the future as therapeutic options for chronic diseases, their administration regimen, such as several times per year, will replace daily medication use. Thus, therapeutic vaccines might be a novel option to control the progression of cardiovascular diseases. Importantly, regarding the development of vaccines against self-antigens (i.e., angiotensin II), the vaccine should efficiently induce a blocking antibody response against the self-antigen without provoking cytotoxic T cells. Therefore, to address the safety and efficiency of therapeutic vaccines, we have developed an original B-cell vaccine to induce antibody production and used carrier proteins, which include exogenous T-cell epitopes through the major histocompatibility complex. In this review, we will introduce the challenges in developing therapeutic vaccines for chronic diseases and describe the therapeutic potential for cardiovascular diseases.

Abstract
Historically, the main classes of drug targets have been receptors, enzymes, ion channels and transporters. However, owing largely to the rise of antibody-based therapies in the past two decades, soluble protein ligands such as inflammatory cytokines have become an increasingly important class of drug targets. In this Review, we analyse drugs targeting ligands that have reached clinical development at some point since 1992. We identify 291 drugs that target 99 unique ligands, and we discuss trends in the characteristics of the ligands, drugs and indications for which they have been tested. In the last 5 years, the number of ligand-targeting drugs approved by the FDA has doubled to 34, while the number of clinically validated ligand targets has doubled to 22. Cytokines and growth factors are the predominant types of targeted ligands (70%), and inflammation and autoimmune disorders, cancer and ophthalmological diseases are the top therapeutic areas for both approved agents and agents in clinical studies, reflecting the central role of cytokine and/or growth factor pathways in such diseases.

Abstract
Hypertension is a common chronic disease affecting a large section of the general population. Hypertension is highly prevalent in the elderly because blood pressure (BP) rises with age. The risk of developing hypertension increases with predisposing genes, intrauterine growth retardation, prematurity and childhood obesity. BP is easier to control in the young. Non-pharmacological treatment through lifestyle changes, such as weight control and leisure-time physical activity, is more likely to be successful in young people. Hypertension in older adults is more difficult to control, requiring the use of more than one antihypertensive drug. Adverse effects and compliance become problematic. Much research is now directed at novel ways of controlling BP such as denervation. The change in definition of hypertension in the American guideline highlights the need to identify and manage hypertension early, at a stage when it is potentially reversible.
