Drogen verändern die neuronale Signalübertragung

Laut einer neuen Studie an Mäusen verändern Drogen wie Kokain und Opioide die neuronale Signalübertragung im Nucleus accumbens (NAc) und kapern ein wichtiges Belohnungssystem des Gehirns, das an der Erfüllung angeborener Überlebensbedürfnisse beteiligt ist. Die Ergebnisse liefern mechanistische Einblicke in die Intensivierung des Drogensuchtverhaltens bei Substanzgebrauchsstörungen. Anhaltender Drogenkonsum geht mit einer tiefgreifenden Neupriorisierung der Motivationen einher, wodurch das Entscheidungsverhalten zu einer kurzsichtigen Fokussierung auf den Drogenkonsum gegenüber anderen angeborenen Bedürfnissen wie Essen oder Trinken von Wasser verzerrt wird, wobei die nachteiligen Folgen oft kaum erkannt werden. Man geht davon aus, dass diese Auswirkungen zum Teil auf Veränderungen im Belohnungssystem des Gehirns zurückzuführen sind, das normalerweise dazu dient, überlebenswichtige Dinge zu identifizieren und darauf zu reagieren. Allerdings bleiben die zugrunde liegenden physiologischen und molekularen Mechanismen, die die angeborenen Gehirnfunktionen verbinden, die durch Drogenkonsum beeinträchtigt werden, unklar. https://www.science.org/doi/10.1126/science.adk6742

Texas Biomed researching vaccines and treatments for highly pathogenic avian influenza

Researchers at Texas Biomedical Research Institute (Texas Biomed) are studying potential vaccines, antivirals and antibodies against highly pathogenic avian influenza, including H5N1 strains that closely mirror the one recently detected in cows, chickens and one person in Texas. This is only the second human case of H5N1 bird flu to be reported in the United States, which officials said was contracted through contact with dairy cows. The influenza subtype primarily infects wild birds and poultry, but has also spilled over into a variety of mammals. This is the first time the avian influenza A(H5N1) virus has been detected in cattle. „Thankfully, the risk of the current H5N1 case becoming widespread among people remains low,“ said Larry Schlesinger, M.D., Texas Biomed President and CEO. „But viruses adapt and evolve – especially influenza viruses – which is why it is so critical to be studying them and… 

EWBG: Substantial advances in Down Syndrome research

This groundbreaking study, conducted by pioneers in bioregenerative medicine and education, uses modern MRI methods to demonstrate a link between cognitive ability and brain volume changes in people with Down Syndrome. These findings suggest that early intervention techniques enhance the quality of life for individuals afflicted. EWBG, known for its groundbreaking work in stem cell therapy, has been at the forefront of this study, working closely with Heidelberg University. This collaboration demonstrates a shared commitment to transforming the care and treatment of Down Syndrome and associated diseases via cutting-edge scientific breakthroughs.
