Artificial cells to serve as the powerhouse of the future

Chloroplasts and mitochondria are responsible for producing energy in nature, which is essential for creating sustainable, artificial cells in the lab. In addition to being “the powerhouses of the cell,” as the adage from middle school biology goes, mitochondria are also one of the most difficult intracellular components to artificially clone.

Effective backup mechanism ensures efficient antimicrobial responses in humans

In the human body, virus particles are identified by pattern recognition receptors (PRRs) either within or on the cell surface. When a receptor is activated, a signaling cascade is initiated, which results in the production and release of signaling molecules like interferons and cytokines.

Study reveals why the FMO5 gene produces an enzyme with a different activity

Our body produces lots of enzymes that break down toxic substances. One class of such enzymes are the flavin-containing monooxygenases (FMOs), which are present in all tetrapods. Humans have five different FMO genes, of which the first four display the same activity. However, the fifth FMO gene triggers a different breakdown reaction. University of Groningen biochemists have succeeded in resurrecting the ancestral genes of all tetrapod FMOs to show how this divergence has occurred. Their results appear on 24 February in Nature Communications.
