Display of clustered antigen by follicular dendritic cells tunes B-cell receptor activation

Ali Shahrokhtash, Hiroaki Ogasawara, Kristian Savstrup Kastberg…·Duncan S. Sutherland

The paper shows that antigen clustering on follicular dendritic cells enhances B-cell receptor activation through geometric control of tyrosine phosphatase exclusion.

Measuring integrin force loading rates using a two-step DNA tension sensor

J. Dale Combs, Alexander K. Foote, Hiroaki Ogasawara…·Khalid S. Salaita

This paper develops a DNA tension sensor to measure integrin force loading rates in live cells, revealing exponential decay in bond lifetime and localized high-force events at cell-substrate junctions.
