Too Much Activity In Certain Areas Of The Brain Is Bad
Neurons in the brain interact by sending each other chemical messages, so-called neurotransmitters. Gamma-aminobutyric acid (GABA) is the most common inhibitory neurotransmitter, which is important to restrain neural activity, preventing neurons from getting too trigger-happy and from firing too much or responding to irrelevant stimuli. Researchers led by Dr Tobias Bast … [Read more...]

Study suggests molecular tools to boost vaccine effectiveness
A powerful arm of the immune system is production of antibodies that circulate through the blood and neutralize invading pathogens. Although B cells actually manufacture antibody proteins, the process is aided by neighboring T cells, which shower B cells with cytokines to make them churn out high-quality antibody proteins--and remember how to do so. Given the essential function … [Read more...]
