Targeting the Effects of Specific Drugs on Pancreatic Islets

The production of insulin and glucagon used to regulate blood sugar levels come from pancreatic islet cells. In individuals with type 1 diabetes, the immune system mistakenly attacks and destroys these cells leaving the body unable to naturally regulate blood sugar. That means that individuals must continuously monitor and manage these levels themselves.

A recent study examined the impact that specific drugs have on pancreatic islet cells and their function. Researchers were able to fine-tune single-cell transcriptomics to remove contamination from RNA molecules that could interfere with results and negatively affect reliability of the data.

Once they had created decontaminated transcriptomes, they tested three different drugs that relate to blood glucose management. They found that one drug, FOXO1, “induces dedifferentiation of both alpha and beta cells,” while the drug artemether “had been found to diminish the function of alpha cells and could induce insulin production in both in vivo and in vitro studies.” They compared these drugs in both human and mouse samples to determine if there were any differences in how the cells responded. One notable difference was that artemether did not have a significant impact on insulin expression in human cells, but in mouse cells, there was reduced insulin expression and overall beta cell identity.

Single-cell analysis of various drugs could help guide future therapeutic treatments for type 1 diabetes as researchers better understand their impact. Targeted therapies have become a greater focus of research as scientists continue to explore T1D at a cellular level.

Diabetes Research Connection (DRC) is interested to see how single-cell sequencing and the ability to decontaminate RNA sequences could affect diabetes research. The organization supports a wide array of T1D-focused studies by providing critical funding to allow early-career scientists to advance their research.

Examining the Co-Occurrence of Asthma and Type 1 Diabetes

It is not uncommon for individuals to have more than one disease or condition at a time. Oftentimes, there is an underlying link between their development, even if it is not entirely understood. In addition, many conditions run in families, which can be due to genetics or even possibly environmental factors.

A recent study looked at data from more than 1.2 million children in Sweden to see if there was a potential association between asthma and type 1 diabetes. They examined risk both within individuals and within families, comparing information from full siblings, half-siblings (both maternal and paternal), full cousins, and half cousins as well.

According to their results, individuals with asthma were at increased risk of developing type 1 diabetes (T1D), but the presence of T1D did not increase their risk of later developing asthma. In addition, if an individual had either T1D or asthma, their full siblings were at increased risk of developing either disease. Full cousins were also at a greater risk.

Data was obtained from several Swedish registers held by the National Board of Health & Welfare and Statistics Sweden and encompassed 1,284,748 singleton children born in Sweden between January 1, 2001, and December 31, 2013. Of these children, 121,809 had asthma, 3,812 had T1D, and 494 had both diseases. Their findings suggest that there may be shared familiar factors that affect associations ranging from genetics to environment.

Understanding these potential associations may help healthcare providers with recognizing symptoms of either disease earlier on if one has already been diagnosed. It may also influence management or treatment of these diseases. More research is necessary to further explore possible connections between asthma and T1D and what that might mean for future care.

Though not involved in this study, the Diabetes Research Connection (DRC) is continually striving to advance research related to T1D by providing critical funding to early-career scientists for their studies. This can lead to improved diagnosis, treatment, and prevention methods, as well as one day finding a cure.

Role of the integrated stress response in type 1 diabetes pathogenesis
In individuals with type 1 diabetes (T1D), the insulin-producing beta cells are spontaneously destroyed by their own immune system. The trigger that provokes the immune system to destroy the beta cells is unknown. However, accumulating evidence suggest that signals are perhaps first sent out by the stressed beta cells that eventually attracts the immune cells. Stressed cells adapt different stress mitigation systems as an adaptive response. However, when these adaptive responses go awry, it results in cell death. One of the stress response mechanisms, namely the integrated stress response (ISR) is activated under a variety of stressful stimuli to promote cell survival. However, when ISR is chronically activated, it can be damaging to the cells and can lead to cell death. The role of the ISR in the context of T1D is unknown. Therefore, in this DRC funded study, we propose to study the ISR in the beta cells to determine its role in propagating T1D.
