Recently, it has been proposed that the disturbance of the nutritional-metabolic sensing pathway is one of the aging characteristics. In particular, nicotinamide adenine dinucleotide (NAD+) plays an important role in this pathway and is considered the regulator of aging. NAD+ regulates an energy metabolism as a co-factor and is also involved in various biological processes including transcription, stress responses, DNA repair, inflammatory responses as well as post-transcriptional modifications, as a substrate for sirtuins, poly ADP-ribose polymerase (PARP), and CD38. With age, DNA damage and chronic inflammation increase in organs, resulting in overconsumption of NAD+ via PARP and CD38. The reduced NAD+ levels decrease the activity of sirtuins and PARPs and impair energy metabolism, ultimately leading to aging and aging-related diseases. However, the precise metabolism of NAD+ in vivo and the mechanism of how NAD+ regulates aging remain elusive. Moreover, the clinical application of NAD+ supplementation therapy is still under development. In this review, we overview the NAD+ metabolism and its relation to aging. In addition, we describe the current issue and perspective of NAD+ supplementation therapy to promote a healthy lifespan.","PeriodicalId":12208,"journal":{"name":"Folia Pharmacologica Japonica","volume":"160 4","pages":"268-273"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144552757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Historically, subcutaneous immunotherapy was the main approach, but with the development of sublingual preparations, which are associated with fewer systemic side effects, sublingual immunotherapy is gaining global popularity. In Japan, the approval of standardized sublingual immunotherapy preparations in 2014 has significantly accelerated its adoption. The mechanism of allergic inflammation is divided into sensitization and elicitation phases. The sensitization phase involves the production of antigen-specific IgE antibodies against a particular antigen. These IgE antibodies bind to FcεRI on mast cells and basophils, preparing the body for an allergic response. The elicitation phase occurs when the body, already primed with these antibodies, is re-exposed to the same antigen, triggering inflammation and symptoms. This phase includes mechanisms where IgE-mediated mast cell activation leads to degranulation and where local Th2 cell activation induces inflammation. While the mechanisms of AIT are not fully understood, they are categorized into desensitization and immune tolerance. Desensitization is induced by reducing the responsiveness of mast cells and basophils to the antigen. Immune tolerance involves the production of antigen-specific IgG4 antibodies that compete with IgE for antigen binding, and the induction of regulatory T cells and other anti-inflammatory immune cells producing cytokines such as IL-10. AIT still faces challenges, such as the lack of predictive biomarkers for efficacy. Recent studies indicate that HLA genotypes influence AIT responsiveness. Advances in genetic and single-cell analysis are expected to address these challenges, paving the way for improved treatment outcomes.","PeriodicalId":12208,"journal":{"name":"Folia Pharmacologica Japonica","volume":"160 1","pages":"43-47"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142931073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Itch not only disturbs daily lives, but also exacerbates inflammation in case of atopic dermatitis (AD). It had been thought that both itch and pain are transduced by the same neurons; however, it is now known that neutrons transducing either itch or pain are distinct. Moreover, TRP channels, a family of calcium channels, play an important role for transducing itch as well as pain, temperature, and pressure. Development of neuroscience and molecular biology has dramatically advanced our understanding of how itch is transduced in recent years. On the other hand, development of immunology has revealed that there exist several immune types in our host defense mechanism and that type 2 immune reaction is dominant in the pathogenesis of allergic diseases including AD. Although it had been already known that type 2 cytokines contribute to the pathogenesis of AD by binding to their receptors on both immune cells and tissue resident cells, it has been recently found that several type 2 cytokines directly transduce the itch signals by binding to peripheral nerves. Due to this discovery, we can understand more deeply the itch mechanism of AD and can develop molecularly targeted drugs for AD targeting type 2 cytokines, which has dramatically changed the treatment of AD. In this review article, we describe the progress of our recent understanding of the itch mechanism and the strategy of treatment against it.","PeriodicalId":12208,"journal":{"name":"Folia Pharmacologica Japonica","volume":"160 2","pages":"79-85"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143536995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our research focused on preventing, managing, and mitigating the adverse effects of treatments for infection with methicillin-resistant Staphylococcus aureus. In this review, we present our investigations utilizing medical big data. The first study aimed to elucidate the relationship between renal outcome and survival following the onset of vancomycin-associated nephrotoxicity (VAN). An initial analysis using the US Food and Drug Administration Adverse Events Reporting System (FAERS) database revealed elevated mortality rates among patients with VAN compared with those without VAN, forming the basis for further investigation. A subsequent, more rigorous, retrospective analysis using electronic medical records confirmed that poor survival outcomes were significantly associated with non-recovery from VAN, particularly when progression to acute kidney injury of stage ≥2 occurred. Therefore, preventing progression to severe VAN is critical for enhancing survival outcomes. The second study investigated the relationship between statin use and daptomycin-related musculoskeletal adverse events. By employing a mixed-method approach combining meta-analysis with disproportionality analysis of the FAERS data, a significant association between statin therapy and daptomycin-related rhabdomyolysis was identified. This highlights the importance of cautious statin and daptomycin use, with careful consideration of potential safety risks. Each medical big-data database possesses unique characteristics that require careful consideration during analysis. The accurate interpretation of medical big data, coupled with its integration with complementary methodologies, will produce more robust and reliable research outcomes across diverse fields.","PeriodicalId":12208,"journal":{"name":"Folia Pharmacologica Japonica","volume":"160 3","pages":"178-183"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143959933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PNH is a rare, chronic hematologic disorder caused by acquired mutations of hematopoietic stem cells in the PIGA gene. These mutations cause deficiencies in complement regulatory proteins CD55 and CD59 that may lead to uncontrolled terminal complement activation, intravascular hemolysis, thrombosis, and premature mortality. Complement C5 inhibitors (C5i; eculizumab and ravulizumab) are the current standard of care of PNH treatment, and control intravascular hemolysis (IVH) by inhibiting terminal complement pathway activation. However, extravascular hemolysis (EVH) with persistent symptoms, such as anemia, occurs in some C5i-treated patients with PNH. EVH is caused by the accumulation of proximal complement C3 fragment on the membrane of surviving PNH-type red blood cells. These cells subsequently undergo phagocytosis in the spleen or liver. Danicopan was developed to control EVH by targeting complement factor D involved in alternative pathway activation. Preclinical studies showed that danicopan selectively inhibits alternative complement pathway activation by reversibly binding to factor D and inhibiting its serine protease activity. A global phase III study (ALPHA study: ALXN2040-PNH-301 [NCT04469465]) investigated danicopan as add-on therapy to ravulizumab or eculizumab in patients with PNH and clinically significant EVH. Danicopan achieved statistically significant, clinically meaningful increases in hemoglobin levels, reduced transfusion, and reduced fatigue, while maintaining control of IVH. No new safety concerns were observed. Danicopan makes it possible to control EVH while controlling IVH with C5i.","PeriodicalId":12208,"journal":{"name":"Folia Pharmacologica Japonica","volume":"160 4","pages":"279-290"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144552781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
