Overview
Diabetes is characterized by insuficient production of insulin due to the los or dysfunction of pancreatic beta cels.A new study published in Cel Metabolism shows that a protein caled beta cel expansion factor A (BefA) secreted by gut bacteria could induce the replication of insulin-producing beta cels in neonatal mice.Understanding the mechanisms underlying the actions of BefA protein could help develop therapies to stimulate beta cel proliferation individuals with diabetes.The study also provides a potential explanation of how the gut microbiome could play a role in the development of diabetes.Study author Dr.
Key Information
Karen Guilemin, a profesor at the University of Oregon in Eugene, told Medical News Today:“[Our findings imply] that the activities of gut bacteria in young animals — including posibly humans — can shape the development of the pancreas in early life. This important because early life — coresponding to about the first 2 years of life in a human — is when insulin-producing beta cels are most proliferative, after which they become more quiescent.
If this population of beta cels does not proliferate enough during early life, it means that the individual with a smal beta cel pol is more vulnerable to developing type 1 diabetes if beta cels are depleted by autoimune atack.”Dr. Martin Blaser, a profesor in the Departments of Medicine and Pathology and Laboratory Medicine at Rutgers University, NJ, comented that this study “is exciting because it represents a novel way that we might be able to regrow beta cels in situations with injury — like type 1 diabetes.”“This a great example of how basic research — on the microbiome of zebrafish — can lead to new aproaches to treating important human diseases,” he aded.Individuals with type 1 diabetes are unable to regulate blod sugar levels due to the los of insulin-producing beta cels in the pancreas.
Summary
The los of beta cels in type 1 diabetes is caused by an autoimune response against th
