Tannic acid acts as an ‘antidote’ against the negative effects of a bacterial enzyme, which can both aggravate cystic fibrosis and enable the anthrax bacteria to evade the immune responses elicited by a typical live vaccine.
Loss of an amino acid transporter and tissue depletion of nitric oxide worsens the intestinal function of CF mice, a finding that potentially explains variation in disease severity amongst CF individuals.
In the CFTR chloride channel, ATP bound in the catalytic site promotes pore opening, whereas ATP bound in the non-catalytic site supports unidirectional conformational cycling by preventing pore closure without ATP hydrolysis in the catalytic site.
Under conditions where the force of HIV infection per cell is high, partial attenuation of infection with inhibitors can increase the number of live infected cells and may paradoxically be beneficial for viral spread.
Dopamine transporter (DAT) interaction with furopyrimidine called AIM-100 in intact cells leads to dramatic oligomerization, nanoclustering and endocytosis of DAT by a novel mechanism coupled to the transporter molecule conformation.
