Cím:	Missing endomysial and reticulin binding of coeliac antibodies in transglutaminase 2 knockout tissues / I. R. Korponay-Szabó, K. Laurila, Zs. Szondy, T. Halttunen, Z. Szalai, I. Dahlbom, I. Rantala, J. B. Kovács, L. Fésüs, M. Mäki

Megjegyzések:	Autoantibodies against transglutaminase 2 (TG2) are thought to be responsible for the endomysial (EMA), reticulin (ARA), and jejunal antibody (JEA) tissue binding of serum samples from coeliac patients but the exclusive role of TG2 in these staining patterns has not yet been established. AIMS: To evaluate whether antigens other than TG2 contribute to EMA/ARA/JEA reactions. PATIENTS: Serum samples from 61 EMA/ARA/JEA positive untreated patients with coeliac disease, 40 dermatitis herpetiformis patients, and 34 EMA/ARA/JEA negative non-coeliac controls were tested. METHODS: TG2 knockout (TG2-/-) and wild-type mouse oesophagus, jejunum, liver, and kidney sections, and TG2-/- sections coated with human recombinant TG2 were used as substrates in single and double immunofluorescent studies for patient IgA binding and tissue localisation of TG2, fibronectin, actin, and calreticulin. RESULTS: None of the patient serum samples elicited EMA, ARA, or JEA binding in TG2-/- morphologically normal tissues. In contrast, 96 of 101 gluten sensitive patient samples (95%) reacted with wild-type mouse tissues and all 101 reacted in EMA/ARA/JEA patterns with TG2-/- mouse tissues coated with human TG2. Serum IgA binding to TG2-/- smooth muscle cells was observed in low titres in 31.1%, 27.5%, and 20.5%, and to TG2-/- epithelium in 26.3%, 5.0%, and 8.8% of coeliac, dermatitis herpetiformis, and control samples, respectively. These positivities partly colocalised with actin and calreticulin but not with TG2 or fibronectin. CONCLUSIONS: EMA/ARA/JEA antibody binding patterns are exclusively TG2 dependent both in coeliac and dermatitis herpetiformis patients. Actin antibodies are responsible for some positivities which are not part of the EMA/ARA/JEA reactions.

Cím:	Microbiome's role in musculoskeletal health through the gut-bone axis insights / Zhengrui Li, Qi Wang, Xufeng Huang, Yinteng Wu, Dan Shan
Dátum:	2024

Megjegyzések:	The interplay between the human microbiome and the musculoskeletal system represents a burgeoning field of research with profound implications for understanding and treating musculoskeletal disorders. This review articulates the pivotal role of the microbiome in modulating bone health, highlighting the gut-bone axis as a critical nexus for potential therapeutic intervention. Through a meticulous analysis of recent clinical research, we underscore the microbiome's influence on osteoporosis, sarcopenia, osteoarthritis, and rheumatoid arthritis, delineating both the direct and indirect mechanisms by which microbiota could impact musculoskeletal integrity and function. Our investigation reveals novel insights into the microbiota's contribution to bone density regulation, hormone production, immune modulation, and nutrient absorption, laying the groundwork for innovative microbiome-based strategies in musculoskeletal disease management. Significantly, we identify the challenges hindering the translation of research into clinical practice, including the limitations of current microbial sequencing techniques and the need for standardized methodologies in microbiome studies. Furthermore, we highlight promising directions for future research, particularly in the realm of personalized medicine, where the microbiome's variability offers unique opportunities for tailored treatment approaches. This review sets a new agenda for leveraging gut microbiota in the diagnosis, prevention, and treatment of musculoskeletal conditions, marking a pivotal step toward integrating microbiome science into clinical musculoskeletal care.
