Journal Club: Newly solved structure of a GABA receptor could offer drug design insights

Posted on January 14, 2019 by Jessica P. Johnson

Neurons message each other with the help of excitatory or inhibitory neurotransmitters. But to actually deliver those messages, the neurotransmitters must dock with protein receptors embedded in the cell membranes of adjacent neurons. Of particular interest in the human brain … Continue reading →

Journal Club: New clues in the mystery of the mechanism of general anesthetics

Posted on January 26, 2018 by Jessica P. Johnson

Anesthetics have been used in surgery since the mid-1800s, but their exact mechanisms of action continue to be the subject of intense investigation. Past studies have suggested they block neurotransmitter receptors postsynaptically. Now a new study, published January 9 in … Continue reading →

Making vaccines not need refrigeration

Posted on April 16, 2013 by pnas

Millions of deaths happen each year from vaccine-preventable diseases because vaccines break down from heat and developing countries often lack ways to properly refrigerate them. Now researchers suggest eggshell-like coatings can make vaccines more thermally stable. Vaccines against polio, smallpox, … Continue reading →
