Forscher der University of Pennsylvania haben herausgefunden, dass die Blut-Hirn-Schranke bei Ameisen eine wichtige Rolle bei der Kontrolle des Verhaltens spielt, das für Ameisenkolonien entscheidend ist. Die Blut-Hirn-Schranke produziert eine spezialisierte Form des Enzyms Juvenile-Hormon-Esterase (Jhe), das Juvenile-Hormon (JH3) abbaut. Dieses Hormon fördert Forschungsverhalten bei sozialen Insektenarbeitern. Die Blut-Hirn-Schranke kontrolliert die Menge des JH3-Hormons, das ins Gehirn der Arbeiterameisen gelangt, was zu unterschiedlichen Hormonspiegeln und verschiedenen Arten von Arbeiterameisen mit unterschiedlichen Aufgaben führt. Die Forscher glauben, dass ähnliche Mechanismen auch eine Rolle im Verhalten von Mäusen spielen könnten. Die Studie verwendete Einzelzell-RNA-Sequenzierung, um die Genaktivität in Ameisengehirnen zu analysieren und stellte fest, dass Jhe nur in Blut-Hirn-Schranken-Zellen vorhanden war. Die Manipulation der Jhe-Enzymwerte verändert das Verhalten der Ameisen, einschließlich der Umstellung von Soldatenameisen auf Forschungsverhalten. Die Forscher beobachteten auch, dass Blut-Hirn-Schranken-Zellen von Mäusen Hormonabbau-Enzyme in höheren Mengen exprimieren, was darauf hindeutet, dass dieser Mechanismus auch bei anderen Organismen, einschließlich Säugetieren, eine Rolle spielen könnte. Weitere Forschung ist erforderlich, um die Verbreitung und den Ursprung dieses Mechanismus zu verstehen. Die Studie wurde vom NIH und NSF unterstützt.

Official Responses and Future Research Directions
The research conducted at the University of Pennsylvania has received recognition and support from various organizations. The National Institutes of Health (NIH) and the National Science Foundation (NSF) have both funded this project, emphasizing its importance in advancing our understanding of brain function and behavior.
Scientists involved in the study have expressed their plans for future research to expand on these initial findings. They aim to further investigate the specific mechanisms through which the blood-brain barrier controls behavior in carpenter ants. This includes studying the regulation of other hormones, such as neuropeptides, and their potential role in behavioral control.
Moreover, researchers are eager to explore the extent to which this mechanism is conserved across different species and the evolutionary origins of this phenomenon. By examining a wide range of organisms, including other insects and mammals, scientists hope to uncover fundamental principles about the control of behavior in complex social systems.
Anticipated future studies will most likely employ advanced techniques such as optogenetics and genetic manipulations to elucidate the precise mechanisms underlying the function of the blood-brain barrier and its influence on behavior.
Conclusion
The recent research conducted at the University of Pennsylvania highlights the crucial role of the blood-brain barrier in controlling behavior within carpenter ant colonies. By regulating the levels of Juvenile Hormone (JH3) through the production of the enzyme Juvenile hormone esterase (Jhe), the blood-brain barrier influences the specialization and organization of worker ants.
These findings open up intriguing possibilities for understanding the control of behavior in other organisms, including mammals. While further research is necessary to fully grasp the extent of this mechanism, the initial discoveries have sparked excitement and curiosity within the scientific community and the general public.
By shedding light on the intricate social dynamics of ants and potentially other species, this research paves the way for future investigations into the biological basis of behavior. The support from organizations like the National Institutes of Health and the National Science Foundation further underscores the significance of this research and the potential impact it may have on our understanding of brain function and behavior in various organisms.
As we delve deeper into the hidden mechanisms underlying social behavior, we not only gain insights into the fascinating world of ants but also uncover fundamental principles that shape the behavior of diverse species, including our own.
