Solving the Puzzle of Immune Tolerance for β-Cell Replacement Therapy for Type 1 Diabetes.

Solving the Puzzle of Immune Tolerance for β-Cell Replacement Therapy for Type 1 Diabetes. Cell Stem Cell. 2020 Oct 01;27(4):505-507 Authors: Bluestone JA, Tang Q Abstract Type 1 diabetes mellitus results from autoimmune destruction of pancreatic β cells. Insulin treatment is often inadequate in preventing devastating complications. Replacing β cells using stem cell-derived islets while fostering immune tolerance, exemplified in Yoshihara et al., holds the promise of a curative therapy for this disease.

Vaccines have been traditionally developed with the presumption that they exert identical immunogenicity regardless of target population and that they provide protection solely against their target pathogen. However, it is increasingly appreciated that vaccines can have off-target effects and that vaccine immunogenicity can vary substantially with demographic factors such as age and sex. Bacille Calmette-Guérin (BCG), the live attenuated Mycobacterium bovis vaccine against tuberculosis (TB), represents a key example of these concepts. BCG vaccines are manufactured under different conditions across the globe generati...

The objective of this report was to summarize current knowledge of CC, squamous intraepithelial lesions, and human papillomavirus (HPV) infection in non-HIV immunocompromised women to determine best practices for CC surveillance in this population and provide recommendations for screening. We evaluated those with solid organ transplant, hematopoietic stem cell transplant, and a number of autoimmune diseases. A panel of health care professionals involved in CC research and care was assembled to review and discuss existing literature on the subject and come to conclusions about screening based on available evidence and expe...

In vitro generation of pancreatic β-cells for diabetes treatment. I. β-like cells derived from human pluripotent stem cells. Folia Histochem Cytobiol. 2019 Mar 14;: Authors: Cierpka-Kmiec K, Wronska A, Kmiec Z Abstract Diabetes mellitus is a chronic disease that affects hundreds of millions of people worldwide. Type 1 diabetes (T1D) is characterized by the lack of pancreatic β-cells that had been destroyed as a result of an autoimmune response. Therefore, in patients with T1D, the replacement therapy with functional β-cells derived from extrinsic sources could be a preferable option...

This study showed that potential vicious cycles underlying ARDs are quite diverse and unique, triggered by diverse and unique factors that do not usually progress with age, thus casting doubts on the possibility of discovering the single molecular cause of aging and developing the single anti-aging pill. Rather, each disease appears to require an individual approach. However, it still cannot be excluded that some or all of these cycles are triggered by fundamental processes of aging, such as chronic inflammation or accumulation of senescent cells. Nevertheless, experimental data showing clear cause and effect relationships...

Exp Clin Endocrinol Diabetes DOI: 10.1055/a-0661-5873Diabetes type 1 (T1D) is a common autoimmune disease characterized by permanent destruction of the insulin-secreting β-cells in pancreatic islets, resulting in a deficiency of the glucose-lowering hormone insulin and persisting high blood glucose levels. Insulin has to be replaced by regular subcutaneous injections, and blood glucose level must be monitored due to the risk of hyperglycemia. Recently, transplantation of new pancreatic β-cells into T1D patients has come to be considered one of the most potentially effective treatments for this disease. Therefore,...

Authors: Farooq T, Rehman K, Hameed A, Akash MSH Abstract Type 1 diabetes mellitus (T1DM) is classified as an autoimmune disease which progressively results in the depletion of insulin-secreting β-cells. Consequently, the insulin secretion stops leading to hyperglycemic situations within the body. Under severe conditions, it also causes multi-organ diabetes-associated dysfunctionalities notably hypercoagulability, neuropathy, nephropathy, retinopathy, and sometimes organ failures. The prevalence of this disease has been noticed about 3% that has highlighted the serious concerns for healthcare professionals aro...

Purpose of review: To describe primary immunodeficiencies caused by gain-of-function (GOF) mutations of signal transducer and activator of transcription (STAT) genes, a group of genetically determined disorders characterized by susceptibility to infections and, in many cases, autoimmune manifestations. Recent findings: GOF mutations affecting STAT1 result in increased STAT tyrosine phosphorylation and secondarily increased response to STAT1-signaling cytokines, such as interferons. In contrast, STAT3 hyperactivity is not usually related to hyperphosphorylation but rather to increased STAT3-mediated transcriptional activit...

Abstract Type 1 diabetes mellitus is a chronic autoimmune disease that results from the destruction of beta (β) cells in the pancreatic islets, leading to loss of insulin production and resultant hyperglycemia. Recent developments in stem cell biology have generated much excitement for β-cell replacement strategies; β cells are one of many cell types in the complex islet environment and pancreas. In this Opinion, we discuss recent successful attempts to generate β cells and how this can be coupled with bioprinting technologies in order to fabricate pancreas tissues, which holds great potential ...
