Summary: Baricitinib, an oral inhibitor of Janus kinase 1 and 2, was evaluated as a treatment for patients with systemic lupus erythematosus (SLE) in a 52-week phase 3 study. The study found that baricitinib did not significantly improve SLE disease activity compared with placebo, and there were no new safety concerns.

Summary: Osteoporosis is a worldwide health issue characterized by imbalanced bone remodeling. The receptor for advanced glycation end product (RAGE), a transmembrane protein in the immunoglobin family, has been involved in many chronic diseases, including osteoporosis. Activation of RAGE signaling negatively affects bone remodeling by regulating osteoblast proliferation and differentiation, as well as osteoclastogenesis. The review discusses the structure of RAGE and its biological functions in the pathogenesis of osteoporosis, suggesting RAGE signaling as a potential therapeutic target.

Summary: Systemic lupus erythematosus (SLE) is a complex autoimmune disease with limited targeted therapy. Recent studies suggest that RNA methylation may be related to the pathogenesis of SLE. Although some evidence supports the association between RNA methylation and SLE pathogenesis, further in-depth research and analysis are needed.

Summary: Smoking is a significant risk factor for COPD, and even after smoking cessation, chronic lung inflammation and COPD progression continue. Current anti-inflammatory therapies are ineffective, highlighting the need for new molecular targets. RAGE, a genetic determinant of low lung function and COPD susceptibility, plays a crucial role in COPD pathogenesis. Both innate and acquired immunity are essential in the development of chronic inflammation and emphysema in COPD, where RAGE and its ligand HMGB1 contribute.

Summary: Hypoxia, characterized by inadequate oxygen supply to tissues, is common in solid tumors. Cellular response to hypoxic conditions is mediated by activating HIFs, which control the expression of many target genes. Recent studies suggest that RAGE signaling plays a crucial role in tumor biology under hypoxic conditions.

Summary: In this study, we investigated the expression levels of CCR4, CCR6 and CXCR3 on Tfh-like cells in the peripheral blood and skin lesions of SLE patients and normal controls. The results showed a decreased expression of CXCR3 on Tfh-like cells in lupus peripheral blood, while an increased expression was observed in skin lesions. Additionally, higher levels of CXCR3 were found in Tfh cells from human tonsils, suggesting a potential role of CXCR3 in guiding Tfh-like cells to migrate to inflammatory sites.

Summary: High doses of aprotinin exert nephrotoxic effects in healthy mice by accumulating in the tubular system, inhibiting proximal tubular function, and counterregulatory stimulation of ENaC-mediated sodium transport. Under a low-salt diet, aprotinin impaired sodium preservation, stimulated excessive hyperaldosteronism, and unexpectedly, activated ENaC.

Summary: Thrombotic microangiopathy, hemolysis and acute kidney injury are typical characteristics of HUS. This study investigated the impact of haptoglobin and hemopexin on HUS. The results showed that haptoglobin deficiency decreased survival rate, while hemopexin deficiency reduced kidney inflammation and thrombotic microangiopathy. Low dose haptoglobin administration attenuated kidney damage. Signs of kidney hemoglobin degradation were observed in HUS.

Summary: This study investigated the significance of light chain (LC) restriction or crystals (LC-R/C) in proximal tubules in the spectrum of LC-induced nephropathies. LC-R/C was found in a quarter of cases analyzed and was strongly associated with cast-NP, suggesting that a high load of clonal LC may be responsible for this phenomenon.

Summary: This study explored the use of gene expression analysis of zero-time biopsies to predict complications in renal transplantation. The results showed marked differences in gene expression profiles between living and deceased donors, with some differentially expressed genes correlating with cold ischemia time. Additionally, immunoglobulin expression was found to be altered in transplants with rejection and previous acute renal failure. Further investigation is needed to confirm these findings in larger cohorts and to clarify the role of early immunoglobulin upregulation in zero-time biopsies.

Summary: Autosomal dominant polycystic kidney disease (ADPKD) is a genetic disorder that leads to the progressive enlargement of kidney cysts and renal failure. Current models for studying human cyst growth and drug trials are limited. In this study, a chorioallantoic membrane (CAM) model was used to culture renal tissue from ADPKD patients and mouse kidney slices, and successfully evaluated cystic tissue growth. The CAM model may provide a valuable platform for bridging the gap between animal studies and clinical trials of human cyst growth.

Summary: This research proposes a novel concept of stain augmentation to develop stain-independent CNNs for digital pathology. It outperforms state-of-the-art techniques and enables segmentation on immunohistochemical stainings without additional annotations, achieving performance comparable to the annotated stain. Examples of application in inflammation and fibrosis quantification are presented, indicating the effectiveness of stain augmentation in deep-learning segmentation algorithms.

Summary: Kidney transplantation is a life-saving strategy for end-stage renal disease patients, but long-term organ survival remains a challenge due to surgical techniques, immunosuppression, and organ shortage. The complement system, part of the innate immune system, plays a crucial role in transplantation-related pathological events. Dysregulation or activation of the complement system can lead to tissue damage and inflammation. This review discusses the role of the complement system in transplantation and potential therapeutic approaches.

Summary: Vitamin D deficiency is highly prevalent worldwide and is associated with the development of systemic lupus erythematosus (SLE) and other immune-mediated diseases. In this study, low vitamin D intake was found to accelerate lupus progression in lupus-prone mice, possibly by affecting the regulatory phenotype of lymphocytes. Correcting vitamin D deficiency can not only prevent osteoporosis but also serve as an important component in the prevention and treatment of lupus and other immune-mediated diseases.

Summary: In this study, the expression of Gpr126 in zebrafish, mice, and humans during kidney development and adulthood was characterized using RNAscope technology. The results showed that Gpr126 was enriched in the epithelial lineage during nephrogenesis and persisted in various cell types in the adult kidney. Single-cell RNA sequencing analysis revealed that Gpr126 expression was detected in a distinct ionocyte sub-population in zebrafish, which is involved in acid secretion, pH buffering, and calcium regulation. The expression patterns of Gpr126 and related genes in mouse kidneys were highly similar. These findings provide insights into the spatio-temporal expression and potential physiological role of Gpr126 in the kidney.
