Today, drugs from a wide range of therapeutic classes are available for the management of the disease. Still, the complications of the condition are difficult to tackle and the side effect profile is quite a concern. The literature indicates that Toll-like receptors (TLRs) and Semaphorins (SEMAs) have been under study for their various pharmacological actions over the past few decades. Both these signalling pathways are found to regulate immunological and inflammatory responses. Moreover, receptors and signalling molecules from the family of TLRs and SEMAs are found to have bacterial recognition and antibacterial properties which are essential in eradicating <i>Helicobacter pylori (H. pylori)</i>, one of the major causative agents of PU. Our understanding of SEMAs, a class of proteins involved in cell signalling, is relatively less developed compared to TLRs, another class of proteins involved in the immune response. SEMAs and TLRs play different roles in biological processes, with SEMAs primarily involved in guiding cell migration and axon guidance during development, while TLRs are responsible for recognizing pathogens and initiating an immune response. Here, in this review, we will discuss in detail the signalling cascade of TLRs and SEMAs and thereby understand its association with PU for future therapeutic targeting. The review also aims at providing an overview of the study that has been into exploring the role of these signalling pathways in the management of PU.</p>","PeriodicalId":11614,"journal":{"name":"Endocrine, metabolic & immune disorders drug targets","volume":" ","pages":"865-878"},"PeriodicalIF":1.9,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10042081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some racial groups and women of childbearing age are more susceptible to SLE pathogenesis. Impressive progress has been made towards a better understanding of different immune components contributing to SLE pathogenesis. Recent investigations have uncovered the detailed mechanisms of inflammatory responses and organ damage. Various environmental factors, pathogens, and toxicants, including ultraviolet light, drugs, viral pathogens, gut microbiome metabolites, and sex hormones trigger the onset of SLE pathogenesis in genetically susceptible individuals and result in the disruption of immune homeostasis of cytokines, macrophages, T cells, and B cells. Diagnosis and clinical investigations of SLE remain challenging due to its clinical heterogeneity and hitherto only a few approved antimalarials, glucocorticoids, immunosuppressants, and some nonsteroidal anti-inflammatory drugs (NSAIDs) are available for treatment. However, the adverse effects of renal and neuropsychiatric lupus and late diagnosis make therapy challenging. Additionally, SLE is also linked to an increased risk of cardiovascular diseases due to inflammatory responses and the risk of infection from immunosuppressive treatment. Due to the diversity of symptoms and treatment-resistant diseases, SLE management remains a challenging issue. Nevertheless, the use of next-generation therapeutics with stem cell and gene therapy may bring better outcomes to SLE treatment in the future.

Stateof- the-art and current challenges","authors":"Ana Miguel Capela, Ana Cunha, Ana Maria Fortuna, Cláudia Falcão Reis","doi":"10.2174/0118715303279986231211090830","DOIUrl":"https://doi.org/10.2174/0118715303279986231211090830","url":null,"abstract":"Introduction:: Inborn errors of metabolism (IEM) are genetic diseases involving congenital disorders of enzyme activities. Most follow Mendelian autosomal recessive inheritance and few follow mitochondrial inheritance. In many cases, after the birth of an affected child parents discover that have been the carriers for the condition and worry about the risk of recurrence in future offspring. Preimplantation genetic testing (PGT) can analyze embryos before their transfer to the uterus and prevent the transmission of hereditary conditions to descendants, however this procedure is of limited value in mtDNA conditions. Methods:: The list of diseases currently approved for PGT were reviewed. The process for eligibility, was as for the Comissão Nacional Procriação Medicamente Assistida (CNPMA), of Portugal (PT). Review of international practices for Assisted Reproductive Techniques (ART) in IEM was carried out. Results:: As of 07.2022, 23 IEM diseases associated with deleterious variants in nDNA were approved for PGT in PT. Couples at risk for conditions not included in the list can solicit an evaluation from an expert committee, after a medical genetics consultation. To qualify for approval, diseases must cause significant suffering and/or premature death. Due to a greater number of solicitations many more IEM conditions have been approved for PGT across the world. ART for mtDNA is not available in PT. International expert centers include PGT for specific well documented variants and mitochondrial donation. Conclusion:: PGT is a reliable approach to reduce the risk of transmission of a genetic condition to the offspring. The list of IEM disorders currently accepted for this technique in Portugal are small, but it is expanding, as many more diseases fit the necessary criteria. While appealing in theory, low success rates coupled with limited availability can be discouraging for patients. Genetic counselling is of paramount importance after the diagnosis of IEM diseases. It is important for both clinicians and patients to be made aware of the available reproductive options and their limitations.","PeriodicalId":11614,"journal":{"name":"Endocrine, metabolic & immune disorders drug targets","volume":"26 2 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138821417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alterations in the gene encoding triggers the enzyme flavin monooxygenase 3 (FMO3), involved in the Sulindac metabolization, which also is responsible for the inherited metabolic disorder. Trimethylaminuria (TMAu, OMIM: 602079). DPYD gene variants are associated with the enzyme dihydropyrimidine dehydrogenase deficiency (DPD; OMIM: 274270). This autosomal recessive metabolic disorder, ultimately leads to the inability to metabolize fluoropyrimidines, which causes severe toxicity in individuals treated with these drugs. Methods:: Variants in genes responsible for the expression of enzymes that encode transporters or receptors involved in the metabolization pathways of certain drugs may condition the individuals response to certain drugs, compromising the therapeutic response and clinical prognosis. Thus the sequencing and identification of variants become relevant, not only gain knowledge on effects of these variants’ on disease causality but also in terms of its side effects resulting from the coding enzymes responsible for drug metabolization. Results:: It was found that patients with the c.472G&gt;A (p.Glu158Lys) and c.923A&gt;G (p.Glu308Gly) polymorphisms, in homozygosity, in FMO3 gene did not develop polyps, thus have a protective effect in the treatment of Familial Adenomatous Polyposis (PAF). However, in the case of the DPYD gene, c.1905+1G&gt;A (IVS14+1G&gt;A), c.1679T&gt;G (p.Ile560Ser), c.2846A&gt;T (p.Asp949Val) e c.1236G&gt;A/HapB3 variants can be lethal in cancer patients indicated for fluoropyrimidine-based chemotherapy. Conclusion:: Knowledge on the drug mechanisms will affect the therapeutic response of patients treated with a given drug. Thus, pharmacogenetics is an essential tool in personalized medicine, since molecular studies allows the clinician to predict the probability of efficacy and toxicity of certain drugs, resulting higher efficiency in individualizing treatment and also improving the safety of the patient. From a personalized medicine perspective, the study of the characteristics of the drug and its metabolization site, the genes involved in the encoding of enzymes responsible for its metabolization will be of great interest.","PeriodicalId":11614,"journal":{"name":"Endocrine, metabolic & immune disorders drug targets","volume":"1 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138818290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This front is important and can help to address several challenges faced by rare disease patients, such as lengthy diagnosis times, difficulty in finding adequate providers of medical services and experts, and adequate treatment if one exists. On another front, there is the need for awareness among citizens and their support in the advocacy for public policies towards rare disease patients and families. Awareness campaigns are prevalent in social networks and fundraising events. In this poster, we present a complementary approach to engage society and promote rare disease awareness through children’s literature and music. A Portuguese teenager wrote a book (‘My Life with my sister’), describing simple and daily moments spent with her teenage sister affected by Sanfilippo syndrome. A professional illustrator designed and illustrated the book. The book is bilingual in Portuguese and English. The author, with the assistance of her music teacher, also composed a song which was recorded with the participation of professional musicians and made into a video clip telling their story and the books. The book and song promote the inclusion and love for people affected by rare diseases and their families. To increase outreach, sister organizations translated the book, adapted the song, and published/ recorded the material in Brazilian Portuguese and French. The proceeds from the sales go towards the Sanfilippo foundations in their respective countries to fund common research projects. The material is being advertised on social media, television, interviews, newspapers, podcasts, libraries, schools, bookshops, book fairs, and others. To date, more than eight hundred books have been sold to individuals and companies. The interviews and video clips add to more than twelve hundred views. The target audience is children, parents, teachers but also companies, and their employees.","PeriodicalId":11614,"journal":{"name":"Endocrine, metabolic & immune disorders drug targets","volume":"17 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138818295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advent of next-generation sequencing (NGS) boosted the discovery of new genetic defects affecting OXPHOS, with pathogenic variants identified in &gt;350 genes to date [1]. However, in many patients, novel variants of unknown clinical significance are found. Subsequent functional studies may clarify its pathogenic consequences and modify the variant’s classification, establishing a genetic diagnosis [2, 3]. Methods:: Analysis of data obtained from patients (P1-P5) with novel genetic causes and functional genomics’ studies performed, namely OXPHOS respiratory/glycolytic rates (Seahorse XF), enzymatic activity and assembly (BN-page), protein levels (SDS-WB), single muscle fiber assay, NGS and bioinformatics. Results/Case Report:: P1-Leigh syndrome (40y, male); Complex IV activity deficiency (full assembly absent), homozygous deletion (c.-11_13del, SURF1), not detected by NGS[2]. P2- Epileptic encephalopathy (8y, male); homozygous c.882-1G&gt;A, FASTKD2; OXPHOS decrease; reduced FASTKD2 expression and abnormal respiratory/glycolytic rates.

Conclusion:: If specific functional results are similar to controls, one might inquire about the pathogenicity of the studied variant and more genetic or bioinformatics analyses and family investigations are needed. There are also limitations of NGS in mutation detection that Sanger sequencing can overcome (P1). When performed first, the OXPHOS activity may guide to genetic screening or interpretation, concordant to later assembly results. All cases were solved and data may be crucial for genetic counseling.","PeriodicalId":11614,"journal":{"name":"Endocrine, metabolic & immune disorders drug targets","volume":"35 9 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138818386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They interfere with adequate energy utilization, namely by muscles, heart, and liver. Treatment aims to maintain patients in an anabolic state, with increased caloric intake, using carbohydrates and medium-chain fatty acids. Treatment with triheptanoin (THP), a synthetic seven-carbon fatty acid triglyceride compound with an anaplerotic effect that increases energy availability to the cell, has been advocated as an efficacious and safe therapy in LC-FAOD. Methods:: Retrospective revision of clinical records of 2 LC-FAOD patients comparing number, severity and admissions for rhabdomyolysis crises, maximum CK values and weight gain in a period of 18 months before and after treatment with THP. Results/Case Report:: Patient 1 is a 12 year old male with VLCADD, with main manifestation being rhabdomyolysis crises. After he started THP we found a decrease in admissions (6 to 2), less rhabdomyolysis crises treated at home (5 to 3), and lower maximum CK values (72352 U/L to 13.000U/L). He had a large increase in weight - 13kg in 18 months. He was able to start pool exercises with no rhabdomyolysis associated. Patient 2 is an 8 year old male with LCAHDD, with main manifestations being rhabdomyolysis crises and retinopathy. After he started THP we found a decrease in admissions (4 to 1), no rhabdomyolysis crises treated at home, and lower maximum CK values (100.000U/L to 19848 U/L). He also increased his weight - 7kg in 18 months. He plays football in school and swims with no rhabdomyolysis associated. In both patients, no major side effects were observed.
