High blood sugar may help cancer cells hide in the immune system.

Recently, there have been a number of recent developments in the field of international medical health that continue to attract the attention of the industry and the public. Cancer cells can sometimes escape the identification and attack of the immune system by surrounding themselves with a dense layer of sugar-rich derivatives. This layer of protection can serve as a disguised form that makes it more difficult for immune cells to identify and kill them.

Researchers at the Sanford Burnham Prebys Medical Discovery Institute and a North American collaborative research institute have now identified the environmental conditions that can help cancer cells build this protective layer. The findings, published in the August 7, 2026 issue of the journal Tumor Science Advancement, suggest that changes in the tumor microenvironment, surrounding immune cells, platelets, blood flow, proteins, and carbohydrates, can affect how effectively cancer cells hide themselves. The researchers also identified a possible way to reduce this sugar-rich coating that could make cancer cells easier to identify and clear by the immune system.

He realized that tumors provide an ideal research environment, as cancer cells are often affected by significant mechanical forces. Primary tumors are typically stiffer than their surrounding tissue, said Tharp, assistant professor in the Cancer Metabolism and Microenvironment Program at the Sanford Burnham Prebys NCI-Designated Cancer Center. This hypothesis guided me to speculate that the biophysical characteristics of the cells would affect their observed differential metabolic processes.

Previous studies have confirmed that this change may depend on what nutrients are present around the cells, i. e. , that this change is not merely an innate characteristic of the cellular characteristics themselves present in the tumor cells themselves.

Further studies required that Tharp and his colleagues grow cells in a variety of different growth conditions in environments exposed to high levels of glucose. Some cells were set up in harsh environments designed to mimic normal conditions similar to those of primitive tumour physics. The researchers also classified the cells into different groups based on the types of culture media used in their growing cell cultures.

One was based on standard laboratory culture, while the other was designed to target nutrients found closer to the human body. Both were tested under normal and high blood sugar conditions, allowing the researchers to compare the adaptation of the two to the nutrients under normal and high blood sugar conditions.
