Flowers aren’t just pretty to look at, they are how plants reproduce. In agricultural plants, the timing and regulation of flower formation has economic significance, affecting a crop’s yield.
Discrimination of Membrane Antigen Affinity by B cells Requires Dominance of Kinetic Proofreading over Serial Triggering
Membrane Antigen Affinity B cells Requires Dominance
2011/1/5
B cells receptor (BCR) signaling in response to membrane-bound antigen increases with antigen affinity, a process known as affinity discrimination. We use computational modeling to show that B cell af...
