Scientists reveal transport mechanism of norepinephrine transporter and binding mode of small molecule and peptide drugs
Noradrenaline (NA) is an important monoamine neurotransmitter in the nervous system. The noradrenaline transporter (NET) located on the presynaptic membrane can transport NA into presynaptic neurons......»»
Breakthrough in plant disease: New enzyme could lead to anti-bacterial pesticides
Plant diseases pose significant challenges to agricultural productivity, presenting formidable hurdles that require urgent attention. Left unchecked, these diseases can spread rapidly, inflicting widespread damage on crops and leading to reduced yiel.....»»
Electrical impedance tomography plus extracellular voltage activation technique simplifies drug screening
When developing new drugs, understanding their effects on ion channels in the body, such as the human ether-a-go-go-related gene (hERG) ion channel found in neurons and heart muscle cells, is critical. Blocking hERG channels can disrupt a normal hear.....»»
