Asthma can protect brain tumors

More than a decade ago, American neurologists made a strange discovery: It appears that people with asthma develop fewer brain tumors than the rest of the population. Today, researchers at Washington University School of Medicine in St. Louis, US, He might understand why.

These scientists discovered the strange behavior of immune cells, called T lymphocytes, when the lungs of asthmatics are inflamed. To understand the role of these lymphocytes, also called the T cell, study members performed several experiments on mice.

Scientists have begun to genetically modify a group of mice to be susceptible to optic nerve tumors. Then they made some of their newborns asthmatic, at 4 to 6 weeks old.

As a result, after three to six months, mice with asthma showed no sign of brain tumors, unlike mice without asthma. Science alert reports. This is where the T cells come in.

One protein, two effects

Through further investigation, the scientists noticed that by the time the mice started developing asthma, the T cells had begun to secrete a protein called decoration. This protein, which is known to damage the airways, will not only have harmful effects, but will also prevent the activation of sentinel cells called microglia. Associated with the growth of cancerous tumors.

Thus, in the researchers’ experiments, asthmatic rodents presented more patterning in their T cells, lymph nodes, and spleen, and especially in their optic nerve, than in non-asthmatic mice, Adds scientific media.

What do we conclude from this? Therefore, members of the team that conducted this study suggested that this T-lymphocyte-derived protein is double-edged: on the one hand, it is harmful to the lungs. On the other hand, it can significantly prevent the emergence of brain tumors. In the future, researchers We hope to develop a treatment Baldecorn against these tumors, without patients developing asthma.
