The distribution of the islets of Langerhans in pancreas of euglycemic spontaneously hypertensive rats

open access: yesPatologìâ, 2016
Considering the fact, that pancreatic beta cells are responsible for production of all insulin needed to maintain the glucose homeostasis, the problem of beta cells pull control in patients with hypertension is rather topical.

Oxygen Supply of Islets of Langerhans by Photosynthetically Active Microalgae in Bioprinted Co‐Cultures Maintains Their Function in a Hypoxic Environment

open access: yesAdvanced Healthcare Materials, EarlyView.
This study developed a bioprinted co‐culture system embedding rat pancreatic islets and Scenedesmus sp. microalgae spatially defined in close vicinity. Red light was found optimal to ensure microalgal photosynthesis while maintaining islet viability and functionality. A tailored co‐culture medium supported both cell types.

Collection of islets of Langerhans using an equilibrium method

open access: yesBioTechniques, 2013
Here we present a convenient method for easy hand selection of enzymatically isolated small tissues such as islets of Langerhans. Islets are continuously collected in a micropipette tip connected to a peristaltic pump.

Decoding the Pathophysiology of Autoimmune Diseases—Mechanism, Triggers, and Nanotherapeutics: A Review

open access: yesAdvanced NanoBiomed Research, EarlyView.
This review highlights how autoimmune diseases arise from intertwined immunological, genetic, and environmental factors, emphasizing gut microbiota dysbiosis as a pivotal driver. It outlines emerging nanotechnology‐based strategies—such as liposomes, hydrogels, and polymeric nanoparticles—that enhance targeted drug delivery, minimize systemic toxicity,

Reinnervation of Isolated Islets of Langerhans Transplanted beneath the Kidney Capsule in the Rat

open access: yesCell Transplantation, 1994
Neural regulation of islets of Langerhans mediates responses to stress and food ingestion. Transplantation of isolated islets offers hope to patients with insulin dependent diabetes mellitus but denervation of isolated islets may affect the capacity for ...

Expression of vitamin D receptor, CYP24A1, and CYP27B1 in normal and inflamed canine pancreases

open access: yesFrontiers in Veterinary Science, 2023
Vitamin D plays a role in anti-inflammatory processes, and the alteration of its metabolism is associated with the inflammatory processes of pancreatitis.

Class-switched anti-insulin antibodies originate from unconventional antigen presentation in multiple lymphoid sites [PDF]

open access: yes, 2016
Autoantibodies to insulin are a harbinger of autoimmunity in type 1 diabetes in humans and in non-obese diabetic mice. To understand the genesis of these autoantibodies, we investigated the interactions of insulin-specific T and B lymphocytes using T ...
