Type 2 diabetes (T2D) is histopathologically characterized by islet amyloid and is closely connected with vascular complications. Here, we explore the presence of pancreatic angiopathy (PA) associated with islet amyloid and T2D.
 
  From a total of 172 autopsy cases who had a history of T2D diagnosis, we randomly selected 30 T2D autopsy cases with islet amyloid (DA+) in comparison with islet amyloid-free (DA-) 30 T2D cases and 60 nondiabetic (ND) controls. Amyloid deposits and PA including atherosclerosis of pancreatic interlobar arteries, arterial calcification, atheroembolism, hyaline arteriosclerosis of small arterioles, and islet capillary density were detected in all groups.
 
  Pancreatic angiopathy was found in 91.7% of patients with T2D and in 68.3% of ND controls (P < 0.01). Furthermore, 100% of DA+ patients and 83.3% of DA- subjects showed PA. The intraislet capillary density was significantly lower in DA+ subjects than DA- subjects (mean [standard deviation], DA+ 205 [82] count/mm; DA- 344 [76] count/mm; ND 291 [94] count/mm; P < 0.01). Finally, interlobar arteriosclerosis (R = 0.603, P < 0.01) was linearly correlated with the severity of islet amyloid deposits.
 
  Pancreatic angiopathy might be both a cause and a consequence of islet amyloid and T2D.

Pancreatic cancer presents dismal clinical outcomes in patients, and the incidence of pancreatic cancer has continuously increased to likely become the second most common cause of cancer-related deaths by as early as 2030. One of main reasons for the high mortality rate of pancreatic cancer is the lack of tools for early-stage detection. Current practice in detecting and monitoring therapeutic response in pancreatic cancer relies on imaging analysis and invasive endoscopic examination. Liquid biopsy-based analysis of genetic alterations in biofluids has become a fundamental component in the diagnosis and management of cancers. There is an urgent need for scientific and technological advancement to detect pancreatic cancer early and to develop effective therapies. The development of a highly sensitive and specific liquid biopsy tool will require extensive understanding on the characteristics of circulating tumor DNA in biofluids. Here, we have reviewed the current status of liquid biopsy in detecting and monitoring pancreatic cancers and our understanding of circulating tumor DNA that should be considered for the development of a liquid biopsy tool, which will greatly aid in the diagnosis and healthcare of people at risk.
  The intestinal microbiota plays a critical role in intestinal homeostasis and immune regulation and has been recognized as a predictor of clinical outcome in patients undergoing allogeneic haematopoietic cell transplantation (allo-HCT) and specifically a determinant of the severity of graft-versus-host disease (GVHD) in mouse models. As GVHD is the most important cause of nonrelapse mortality (NRM) after allo-HCT, understanding the mechanisms by which modifying the microbiota may prevent or decrease the severity of GVHD would represent an important advance.
 
  Microbiota injury was observed globally and higher diversity at peri-engraftment was associated with lower mortality. Lactose is a dietary factor that promotes post-allo-HCT Enterococcus expansion, which is itself associated with mortality from GVHD in patients and exacerbates GVHD in mice. Bacterial and fungal bloodstream infections are preceded by intestinal colonization with a corresponding organism, supporting the gut as a source for many bloodstream infections.  https://www.selleckchem.com/products/cinchocaine.html  Metabolomic profiling studies showed that GVHD is associated with changes in faecal and plasma microbiota-derived molecules.
 
  In this review, we highlight some of the most recent and important findings in clinical and mouse microbiota research, as it relates to allo-HCT. Many of these are already being translated into clinical trials that have the potential to change future practice in the care of patients.

  Controlling T cell activity through metabolic manipulation has become a prominent feature in immunology and practitioners of both adoptive cellular therapy (ACT) and haematopoietic stem cell transplantation (HSCT) have utilized metabolic interventions to control T cell function. This review will survey recent metabolic research efforts in HSCT and ACT to paint a broad picture of immunometabolism and highlight advances in each area.
 
  In HSCT, recent publications have focused on modifying reactive oxygen species, sirtuin signalling or the NAD salvage pathway within alloreactive T cells and regulatory T cells. In ACT, metabolic interventions that bolster memory T cell development, increase mitochondrial density and function, or block regulatory signals in the tumour microenvironment (TME) have recently been published.
 
  Metabolic interventions control immune responses. In ACT, efforts seek to improve the in-vivo metabolic fitness of T cells, while in HSCT energies have focused on blocking alloreactive T cell expansion or promoting regulatory T cells. Methods to identify new, metabolically targetable pathways, as well as the ability of metabolic biomarkers to predict disease onset and therapeutic response, will continue to advance the field towards clinically applicable interventions.
