Summary: Diabetes mellitus, affecting nearly 536.6 million people worldwide, is primarily caused by the death or dysfunction of beta cells in the pancreas. Studies suggest that interactions between neighboring cells in the pancreas play a crucial role in supporting beta cell function.

Summary: Severe acute malnutrition can lead to impaired pancreatic function, including malabsorption and glucose metabolism disorders. Current research has found that exocrine pancreas function is generally impaired, insulin production is low, and glucose disappearance varies in malnourished individuals. Treatment of malnutrition improves some abnormalities, but full recovery is often not achieved. Further large-scale studies are needed to address pancreatic abnormalities in malnutrition and diabetes for better prevention and treatment methods.

Summary: Peroxisomal dysfunction disrupts cellular metabolism by causing the accumulation of toxic intermediates and depletion of important lipids, leading to various diseases. Recent studies have shown the relevance of peroxisomal metabolism in pancreatic cell functionality. Our study aimed to analyze the density of peroxisomes in mouse endocrine and exocrine pancreas and investigate the changes in peroxisomal proteins during postnatal pancreatic maturation. Our results demonstrate that endocrine and exocrine pancreatic cells contain abundant peroxisomes with heterogeneous protein content, suggesting distinct functions for different cell types. Significant postnatal changes occur in the peroxisomal compartment of pancreatic cells, which are crucial for pancreatic development and differentiation.

Summary: This study aimed to assess the endocrine and exocrine functions of patients with pancreatic trauma following partial pancreatectomy. The results showed that some patients developed pancreatic insufficiency and an increase in pancreatic volume post-surgery, indicating the need for further research in a larger study.

Summary: The study demonstrates that EUS-SWM method can serve as a precise tool for diagnosing chronic pancreatitis and determining exocrine/endocrine dysfunctions. EUS-SWM value is positively correlated with the Japan Pancreatic Society criteria stages, effectively distinguishing patients.

Summary: This study identified a population of cells in the pancreas that transiently express the stem-cell marker Lgr5 during late gestational stages, which can differentiate into alpha-cells and undergo spontaneous lineage conversion from alpha- to beta-cells specifically after parturition. This novel mechanism of Lgr5 progeny contributing to the beta-cell compartment through an alpha-cell intermediate phase early after pregnancy may counterbalance against excessive beta-cell mass reduction during beta-cell involution.

Summary: Unraveling cell fate plasticity in the pancreas, we found that acinar-to-ductal transdifferentiation occurs under pathophysiological conditions but not during homeostasis or after partial pancreatectomy. Conversely, pancreatic ductal cells contribute to new acinar cells after significant acinar cell loss. By tracing cell proliferation, we quantified the dynamics and turnover rate of pancreatic exocrine lineages during homeostasis. These findings reveal the occurrence of lineage transdifferentiation between acinar and ductal cells in the pancreatic exocrine glands under specific conditions.

Summary: The present study found that neurotensin and xenin effectively stimulate pancreatic exocrine secretion in sheep through the peripheral cholinergic system, but NTR-2 is not involved in the regulation of pancreatic exocrine secretion, and the role of NTR-1 in this process remains unclear.

Summary: This study investigated GBA1 variants in a large Chinese cohort of patients with Parkinson's disease (PD) and healthy controls, finding that the frequency of GBA1 variants in PD patients was higher than in the control group. The study also found that patients with GBA1 variants had an earlier onset age and a higher risk of certain clinical symptoms.

Summary: In this study, POLG patient-induced pluripotent stem cell (iPSC)-derived neural stem cells (iNSCs) were investigated to understand the impact of POLG mutations on mtDNA maintenance. It was found that iNSCs carrying compound heterozygous POLG mutations had delayed mtDNA level restoration, while iNSCs with homozygous POLG mutation recovered at a similar rate to controls. Moreover, supplementation of deoxyribonucleosides (dNs) reduced mtDNA depletion and increased repopulation rates in patient iNSCs. These findings suggest that POLG mutations impair mtDNA repopulation and dNs supplementation may offer a new therapeutic approach for mitochondrial diseases caused by disturbed mtDNA homeostasis.

Summary: The synthesis of bile acids in PSC patients is associated with therapeutic efficacy, and reduced bile acid synthesis is associated with decreased liver transplantation-free survival. In some patients, bile acid synthesis may be fully suppressed, making further pharmacological intervention futile.

Summary: This study investigated the longitudinal change in Enhanced Liver Fibrosis (ELF) test and liver stiffness measurements (LSM) over a 5-year period in patients with Primary Sclerosing Cholangitis (PSC). The results showed that both ELF and LSM increased over time, with ELF potentially demonstrating superior reliability for risk stratification compared with LSM in PSC.

Summary: The plasma concentration of ITIH4 was significantly elevated in patients with PBC and PSC, with correlations observed with IgM levels and lower concentrations in responders to UDCA treatment. Increased ITIH4 staining was seen in immunohistochemistry, indicating its potential role as a biomarker in cholestatic liver diseases.
