Research Articles
- Endogenous retinoid X receptor ligands in mouse hematopoietic cells
The long-chain fatty acid C24:5 is likely an endogenous ligand of the retinoid X receptor α in mouse hematopoietic cells.
- MARK3-mediated phosphorylation of ARHGEF2 couples microtubules to the actin cytoskeleton to establish cell polarity
A phosphorylation switch releases sequestered ARHGEF2 from microtubules, enabling actin remodeling and formation of three-dimensional cell structures.
Research Resource
- Quantitative single-molecule imaging of TLR4 reveals ligand-specific receptor dimerization
Superresolution imaging of the pattern recognition receptor TLR4 reveals how different ligands control receptor dimerization.

About The Cover
Online Cover This week features a Research Resource that reveals by superresolution imaging how different ligands control dimerization of the pattern recognition receptor TLR4. The image shows the crystal structure of mouse TLR4 in complex with its co-receptor MD-2 and the agonist LPS. [Image: PDB ID 3VQ2 visualized with the UCSF Chimera package]
