Since bacterial infection is one of the main causes of sepsis, appropriate antimicrobial therapy remains the cornerstone of sepsis and septic shock management. However, since sepsis is a multifaceted chaos involving inflammation and anti-inflammation disbalance leading to the unregulated widespread release of inflammatory mediators, cytokines, and pathogen-related molecules leading to system-wide organ dysfunction, the whole body control to prevent the progression of organ dysfunction is needed. In sepsis and septic shock, pathogen-associated molecular patterns (PAMPs), such as bacterial exotoxins, cause direct cellular damage and/or trigger an immune response in the host. PAMPs are recognized by pattern recognizing receptors (PRRs) expressed on immune-reactive cells. PRRs are also activated by host nuclear, mitochondrial, and cytosolic proteins, known as damage-associated molecular patterns (DAMPs) that are released from cells during sepsis. Thus, most PRRs respond to PAMPs or DAMPs by triggering activation of transcriptional factors, NF-κB, AP1, and STAT-3. On the other hand, sepsis leads to immune (lymphocytes and macrophages) and nonimmune (endothelial and epithelial cells) cell death. Apoptosis has been the major focus of research on cell death in sepsis, but autophagy, necrosis, necroptosis, pyroptosis, NETosis, and ferroptosis may also play an important role in this critical situation. The recent development in our understanding regarding the cellular pathogenesis of sepsis will help in developing new treatment of sepsis.","PeriodicalId":12208,"journal":{"name":"Folia Pharmacologica Japonica","volume":"159 2","pages":"101-106"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140021328","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}

In 2016, Carhart-Harris and colleagues reported that psilocybin, the hallucinogenic compound derived from magic mushrooms, exhibits rapid and enduring antidepressant effects in patients with treatment-resistant depression. Subsequent clinical studies have found the therapeutic potential of psilocybin in MDD, depressive episode in bipolar disorder, anorexia, and drug addiction. In 2018 and 2019, the U.S. Food and Drug Administration designated psilocybin as a \"breakthrough medicine\" for treatment-resistant depression and MDD, respectively. Notably, the side effects of psilocybin are limited to transient and mild issues, such as headache and fatigue, suggesting its safety. In 2023, we published a review on the role of serotonin 5-HT2A receptors in the antidepressant effects of serotonergic psychedelics (Nihon Yakurigaku Zasshi, Volume 158, Issue 3, Page 229-232).

The primary treatment is pain control and fertility preservation, and while preserving ovarian function through drug therapy and surgery, assisted reproductive technology (ART), including in vitro fertilization (IVF), is also utilized. Hormonal therapies such as low-dose estrogen/progestin (LEP), progestins, and GnRH analogs are often the drug of choice. We presented that IAP (inhibitor of apoptotic protein) inhibitors can potentially be novel agents for treating endometriosis. Our studies using cultured cells derived from human endometriotic lesions and mouse models have revealed that inflammatory cytokines and antiapoptotic factors (IAPs) produced by peritoneal macrophages or endometriosis cells are crucial and that NF-κB (nuclear factor-kappa B) plays a central role in the pathogenesis of endometriosis. The high expression of IAPs in human endometriotic tissues, its facilitative role in ectopic survival, and the effect of IAPs on drug-resistant apoptosis of human endometriotic cells indicate its potential as a novel drug for IAP inhibitors. We found that the medicinal herb parthenolide and selective estrogen receptor modulators (SERM) can reduce lesions through NF-κB inhibition. Recently, new findings were obtained by non-invasive observation of early lesions using bioluminescence technology and by applying knockout mouse models. We will show the possibility of new therapeutic agents for endometriosis.","PeriodicalId":12208,"journal":{"name":"Folia Pharmacologica Japonica","volume":"159 6","pages":"368-373"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142575585","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}

In order to overcome this situation, pharmaceutical companies struggle to improve the probability of success drug research and development with multiple approaches. Recently, it is important to predict the clinical effects of the candidates as early as possible in drug discovery stage, to stratify patients with diseases, and to provide appropriate readouts for evaluation of pharmacological efficacy for increasing the success rate. In this environment, the importance of non-clinical research that actively utilizes human-derived samples including patient-derived samples is increasing. In this article, author describes the use of human-derived samples in non-clinical research, especially focusing on the utilization of induced pluripotent stem cells. Human-derived samples are valuable experimental materials that have, at least in part, human-specific characteristics that experimental animals do not possess. In particular, patient-derived samples are thought to have the genetic predisposition and at least some disease characteristics that cause the disease, and are useful from the perspective of elucidating the pathogenesis, disease modeling, and predictability of clinical effects. This is also valuable for drug discovery research in diseases that are difficult to reproduce in experimental animals such as mice. Whereas, human-derived samples have some limitations, and we need ethical procedures and consideration when researchers use them. Author will provide an overview of the use of human-derived samples in non-clinical research based on the perspectives as described above and introduce our research group cases, and future research prospects using them.","PeriodicalId":12208,"journal":{"name":"Folia Pharmacologica Japonica","volume":"159 5","pages":"290-294"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142105886","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}

In particular, with the aim of improving the efficiency of drug discovery research by utilizing human samples/data, we have established a human sample utilization support capability, then we are supporting the acquisition of appropriate human samples/data to meet each drug research need with collecting information on organizations that can provide various human samples and accumulating know-how on obtaining human samples/data. In addition, we have built a one-stop support system for surveying human samples/data, negotiating, and contracting with the organizations, obtaining ethical committee approvals, importing samples, and dealing with customs clearance. As results, our researchers can obtain high-quality human samples/data to meet their research needs rapidly/easily. By establishing this capability, the number of the research projects that implement target validation, pharmacological evaluation, BM identification, and patient stratification, etc. using human samples/data from the early stage of drug discovery, has increased, and then, the evidence obtained by using human samples/data contribute to create drug candidates with high probability of clinical effect.

Hence, targeting spinal cord astrocytes for the development of useful analgesics has attracted much attention. In the CNS, connexin43 (Cx43), a membrane protein expressed and functioning exclusively in astrocytes, is well known to be involved in intercellular signaling as a component of gap junction, but also interacts with intracellular molecules via its characteristically long C-terminal region, thereby affecting cellular function. Previously, we found that Cx43 expression was markedly reduced in spinal dorsal horn astrocytes from a mouse model of neuropathic pain. In order to investigate the relationship between reduced Cx43 expression in spinal astrocytes and the onset of pain, we showed that reduced Cx43 expression altered the expression of pain-related molecules such as the glutamate transporter GLT-1 and the pro-inflammatory cytokine interleukin-6 (IL-6). In particular, we focused on the regulation of IL-6 expression by reduced Cx43 expression in both in vivo and in vitro analyses, and found that IL-6 expression is increased through the Akt- glycogen synthase kinase-3β (GSK-3β) signaling system driven by reduced Cx43 expression during neuropathic pain, which in turn triggers pain. These findings suggest that astrocyte Cx43 is involved in pain prolongation by regulating gene expression of nociceptive factors through interactions with intracellular signaling molecules, which is different from its previously known function, and thus raises expectations for its potential as a new drug target for chronic pain.","PeriodicalId":12208,"journal":{"name":"Folia Pharmacologica Japonica","volume":"159 6","pages":"363-366"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142575608","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}

However, no effective drug applicable for clinical use has been developed. Recently, the FDA approved Lecanemab, an antibody drug that acts as an aggregation inhibitor against Amyloid-beta (Aβ), for AD treatment. However, there are still no fundamental drugs for AD. In this study, we present a strategy for AD treatment that removes Aβ by cleavage reaction using one of the Catalytides, JAL-TA9 (YKGSGFRMI). A single dose of JAL-TA9 administered into the CA1 region of the hippocampus and the intraventricular space improved the deficits in short-term memory of APP-knock-in mice. It also improved the memory of Aβ25-35-induced model mice, as evaluated by the Y-maze and objective recognition tests. These data strongly suggest that JAL-TA9 could be effective in treating AD. However, these administration methods are difficult to apply clinically due to their high invasiveness. Thus, we tested the improvement effects of dementia by administering JAL-TA9 nasally. It is very interesting and exciting that the dementia of Aβ25-35 induced AD model mice was improved by four applications once every three days. These results strongly suggest that JAL-TA9 is the best candidate for AD treatment because it is effective even in the late stage of AD.","PeriodicalId":12208,"journal":{"name":"Folia Pharmacologica Japonica","volume":"159 6","pages":"391-395"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142575609","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}

Pharmacogenetic biomarkers useful in clinical practice include drug-metabolizing enzyme and drug transporter genes and human leukocyte antigen (HLA) genes. HLA genes, which are important molecules involved in human immunity, have long been analyzed for associations with ADRs, such as skin rash, drug-induced liver injury, and agranulocytosis. HLA is composed of many genes, each of which has dozens of different types (alleles), and many HLA alleles associated with ADRs have been reported. The odds ratios in the association of HLA alleles range from approximately 5 to several thousand, indicating a very large impact on the risk of ADRs. Thus, HLA genetic testing prior to initiation of drug therapy is expected to make a significant contribution to avoiding ADRs, but to demonstrate the clinical utility, it is necessary to prospectively show the effects of medical interventions based on the test results. We conducted the GENCAT study, a prospective, multicenter, single-arm clinical trial to investigate the impact of a therapeutic intervention based on the HLA-A*31:01 test on the incidence of carbamazepine-induced skin rash. HLA-A*31:01-positive patients were treated with an alternative drug such as valproic acid, and the study showed an approximately 60% reduction in the incidence of carbamazepine-induced skin rash. It is expected that the genetic test, which has demonstrated clinical utility, will lead to the establishment of safer and more appropriate stratified medicine by reflecting the information in clinical practice guidelines.","PeriodicalId":12208,"journal":{"name":"Folia Pharmacologica Japonica","volume":"159 2","pages":"90-95"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140021330","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}
