Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

CHAIN TRANSMISSION-RELIABLE AND EFFICIENT

RUSSIAN ELECTRONIC SCIENTIFIC JOURNAL, 2020
Chains used in mechanical engineering by the nature of their work are divided into three main groups: drive, traction and cargo. Drive chains are the most common. They transmit movement from the energy source to the receiving organ of the machine.
