Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Redox Regulation of a Light-Harvesting Antenna Complex in an Anoxygenic Phototroph

mBio, 2019
The purple nonsulfur bacterium Rhodopseudomonas palustris is a model for understanding how a phototrophic organism adapts to changes in light intensity because it produces different light-harvesting (LH) complexes under high light (LH2) and low light ...

Sensing the light: photoreceptive systems and signal transduction in cyanobacteria [PDF]

Molecular Microbiology, 2007
SummaryPhotosynthetic prokaryotes have highly developed abilities to detect and react to environmental signals. Light sensing is one of the most important capabilities of organisms that use light for photosynthesis and photomorphogenesis. This review addresses photoreception in cyanobacteria from the perception of light through the physiological ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Regulation by Light of Chemotaxis to Nitrite during the Sexual Life Cycle in Chlamydomonas reinhardtii

Plants, 2014
Nitrite plays an important role in the nitrogen metabolism of most cells, including Chlamydomonas reinhardtii. We have shown that vegetative cells of C. reinhardtii are attracted by nitrite.

Optogenetics - Bringing light into the darkness of mammalian signal transduction

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2017
Cells receive many different environmental clues to which they must adapt accordingly. Therefore, a complex signal transduction network has evolved. Cellular signal transduction is a highly dynamic process, in which the specific outcome is a result of the exact spatial and temporal resolution of single sub-events.
