Orthogonal microfluidic approaches reveal force-enhanced migration of bacterial populations on surfaces

Piyush Sharma, Michael J Marcheschi, Alexander M. Shuppara, Joseph E. Sanfilippo

This study shows that increased shear force enhances upstream migration of Pseudomonas aeruginosa by increasing twitching motility speed through changes in cell orientation.

An early, novel arginine methylation of KCa3.1 attenuates subsequent T cell exhaustion.

Piyush Sharma, Ao Guo, Suresh Poudel…·Douglas R. Green

The paper shows that early arginine methylation of KCa3.1 limits Ca2+-mediated NFAT1 activation, preventing T cell exhaustion during activation.
