🔬 Advancing Therapies for Lysosomal Storage Diseases: The Role of Cyclodextrins This week, let’s delve into the fascinating world of cyclodextrins and their potential impact on treating lysosomal storage diseases (LSDs). These rare genetic disorders arise from defects in lysosomal function, leading to an abnormal buildup of toxic materials within cells. Approximately 50 different types of LSDs exist, including Gaucher disease, Fabry disease, and Pompe disease. Symptoms can vary widely but often include developmental delay, movement disorders, and early death. Treatment Approaches - Enzyme Replacement Therapy: Administering missing enzymes. - Substrate Reduction Therapy: Reducing the accumulation of toxic substances. - Supportive Care: Managing symptoms and complications. Early Diagnosis: Crucial for improving prognosis and quality of life. Cyclodextrins are promising agents; these cyclic oligosaccharides enhance the solubility of hydrophobic substances. Currently used in Niemann-Pick Disease Type C (NPC) therapy: A lysosomal storage disorder resulting from mutations in cholesterol transporter genes (NPC1, NPC2). Cholesterol accumulates within lysosomes. Hydroxypropyl-β-Cyclodextrin (HP-β-CD) is used in compassionate scenarios and clinical trials for NPC patients. It is promising, but concerns about ototoxicity persist. Expanding Horizons - Ongoing Research: Basic and clinical studies continue to explore HP-β-CD’s efficacy. -Superior CD Derivatives: Investigating other cyclodextrins for clinical application. - Broader Applicability: Considering CD therapies for various LSDs. Other LSDs: Methyl-β-cyclodextrin (MBCD), alpha-cyclodextrin (α-CD), gamma-cyclodextrin (γ-CD), and HPBCD (Kleptose) show potential in cell models in these diseases: Wolman disease, Farber disease, Tay-Sachs disease, Fabry disease, Niemann Pick Type A (NPA), Batten disease, and Mucopolysaccharidosis type IIIB (MPSIIIB). 🌟🔍🧪 #LysosomalStorageDiseases #Cyclodextrins #MedicalResearch

📃Scientific paper: Factors affecting responsiveness of vadadustat in patients with anemia associated with chronic kidney disease: a post-hoc subgroup analysis of Japanese phase 3 randomized studies Ref.: Springer, 2024 Abstract: Background Vadadustat is an oral hypoxia-inducible factor prolyl hydroxylase inhibitor developed for treating anemia in chronic kidney disease (CKD). The purpose of this post-hoc analysis was to investigate the factors affecting the responsiveness to vadadustat in anemia patients with nondialysis-dependent (NDD) or hemodialysis-dependent (HDD) CKD in two Japanese phase 3 studies. Methods Of 151 and 162 patients enrolled in NDD-CKD and HDD-CKD studies, 136 and 140 patients, respectively, were included and divided into subgroups for the analysis. To assess vadadustat responsiveness, the resistance index was defined as the mean body weight-adjusted dose of vadadustat (mg/kg) at weeks 20–24 divided by the mean hemoglobin (g/dL) at weeks 20–24. Multivariate analysis was performed to identify the variables affecting the resistance index. Results Independent factors identified as determinants for better response to vadadustat were as follows: high baseline hemoglobin, low baseline eGFR, high week-20–24 ferritin, and CKD not caused by autoimmune disease/glomerulonephritis/vasculitis in NDD-CKD; and male sex, high baseline C-reactive protein, and low baseline erythropoiesis-stimulating agent resistance index (ERI) in HDD-CKD. Conclusions In this post-hoc analysis, several factors were identified as affecting the response to vadadustat. These results may provide useful information leading to an appropriate dose modification for vadadustat. Clinical trial registration NCT03329...

Taming the #Immune #System When #rarediseases Strike:- •Rare diseases suffer from a myriad of challenges, including misdiagnosis, no diagnosis, or lack of appropriate treatments. •A subset of such conditions includes 80–90 types of rare #autoimmune disease. •Companies that develop #therapeutics for rare autoimmune diseases are utilizing a number of strategies. •For example, drugs to treat sarcoidosis, (in which damaging granulomas form throughout the body) are being developed that target #tRNA #synthetase domains involved in both normal cellular responses as well as autoimmune conditions. ✓ Another strategy recycles an approved drug given Orphan Disease Designation to treat a rare #Bcell driven disease that causes #skin and #lung fibrosis. 1.#tRNA #synthetase #therapeutics:- •Amino-acyl tRNA synthetases are enzymes that catalyze the attachment of amino acids to their specific tRNA. •The resulting tRNAs are escorted into the ribosomal machinery where they enter into the protein synthesis pathway. •tRNA synthetases evolved to include novel domains that may more broadly play critical roles to cellular responses involved in disease states, in particular, cellular stress, and tissue homeostasis. 2.#Targeting #Bcells:-GSK has its sights on treatment of SSc-ILD. Their strategy, however, is targeted B-lymphocyte stimulator (#BlyS) inhibition using belimumab to patients affected by B cell-mediated immune conditions. •Their strategy, however, is #targeted #B- #Lymphocyte stimulator (BlyS) inhibition using belimumab to patients affected by B #cell-mediated immune conditions. The drug, a fully humanized #monoclonal antibody, #prohibits the prolonged survival of B cells induced by increased #BlyS and reduces the differentiation of B cells into #immunoglobulin-producing #plasma cells. •The #fda has already approved the #belimumab (Benlysta) for the treatment of active #systemic #lupus #erythematosus (SLE) and #lupus #nephritis. 3.#Melanocortin #analog for #vitiligo:- #Vitiligo is an autoimmune disorder resulting in loss of skin pigment. •The condition, affecting ~ 0.5 to 2% of the world’s population, occurs when #pigment-producing #melanocytes are destroyed. Loss of skin color often first appears on the hands and face then spreads to other body parts. •There is currently no clinically meaningful, safe systemic treatment option.However, a systemic disease needs a systemic solution. We are focusing on the therapeutic potential of #melanocortins, a group of #small #peptide hormones derived from the cleavage of the larger #proopiomelanocortin (POMC) protein.” •In particular, the company has developed a 13 amino acid #analog of #alpha-melanocyte #stimulating hormone (#alpha-MSH), a naturally occurring peptide that stimulates #melanogenesis. The compound, #SCENESSE® (#afamelanotide), plays a role in regulating (that is, stimulating) #pigmentation similar to #alpha-MSH. #autoimmunedisease #tcells #proteins #immunology

🧬 Groundbreaking Discovery in Bowel Disease: Scientists Identify Key Driver and Pioneer Drug Adaptation for Treatment🧬 Researchers have made a significant breakthrough in understanding the drivers of Inflammatory Bowel Disease (IBD) and other related disorders. Their work is now focused on adapting existing drugs to effectively treat patients, marking a potential 'holy grail' in the fight against these debilitating conditions. Increasing rates of autoimmune and inflammatory diseases present a burgeoning threat to human health, compounded by limited efficacy of available treatments and high failure rates during drug development. To address this urgent need for a better understanding of disease mechanisms, recent research explores the potential of functional genomics. 🔬 This study investigates an intergenic haplotype on chr21q22, linked to multiple inflammatory diseases such as inflammatory bowel disease, ankylosing spondylitis, primary sclerosing cholangitis, and Takayasu’s arteritis. The researchers identify ETS2 as a central regulator of human inflammatory macrophages, delineating the shared mechanism amplifying ETS2 expression. 🧩 Genes regulated by ETS2 are prominently expressed in diseased tissues, with a strong enrichment for inflammatory bowel disease GWAS hits. Overexpressing ETS2 in resting macrophages replicates the inflammatory state observed in chr21q22-associated diseases, upregulating multiple drug targets, including TNF and IL-23. 💡 Using a database of cellular signatures, the researchers identified and validated the potent anti-inflammatory activity of one class of small molecules in vitro and ex vivo. ✨ This work showcases the power of functional genomics in identifying immune-mediated disease mechanisms and potential therapeutic opportunities, paving the way for more effective treatments for inflammatory diseases.

🌟 𝗥𝗲𝘀𝗲𝗮𝗿𝗰𝗵 𝗨𝗽𝗱𝗮𝘁𝗲 🌟 A part of our work on the effects of high intracellular calcium on T cell activation is now published in 𝘐𝘯𝘵𝘦𝘳𝘯𝘢𝘵𝘪𝘰𝘯𝘢𝘭 𝘐𝘮𝘮𝘶𝘯𝘰𝘱𝘩𝘢𝘳𝘮𝘢𝘤𝘰𝘭𝘰𝘨𝘺. It is well-known that calcium influx is necessary for T cell activation. Counterintuitively, our observations suggest that high calcium levels actually inhibit activated-associated T cell proliferation, while also promoting T cell death! We also show that tert-butyl hydroquinone (tBHQ) additively increases calcium levels, in turn decreasing activation-associated proliferation of T cells. Notably, tBHQ alleviates colitis symptoms in mice. 🔬 𝗪𝗵𝘆 𝗧𝗵𝗶𝘀 𝗠𝗮𝘁𝘁𝗲𝗿𝘀: These findings indicate that high calcium could be a potential therapeutic target for autoimmune diseases. Modulating calcium levels may better control immune responses, especially in conditions like colitis, rheumatoid arthritis, and more. While calcium inhibitors have been used to treat these autoimmune conditions, our study suggests that calcium enhancers could exert similar effects. The study also points to the potential implications of using calcium-enhancing drugs (to treat various diseases) on immune cells, especially T cells! Further studies are needed to elucidate these details. 🙏 𝗖𝗵𝗲𝗲𝗿𝘀: Cheers to my co-authors and advisors — Tanisha Kumar, Nikita Ramteke, Kaushik Chatterjee and Dipankar Nandi — without whom I could not have accomplished this! 📄 𝗙𝘂𝗹𝗹 𝗣𝗮𝗽𝗲𝗿 𝗟𝗶𝗻𝗸: https://lnkd.in/ghn-kqmZ #TCells #TCellActivation #Calcium #tBHQ #AutoimmuneDiseases #InflammatoryBowelDisease
