First, the authors demonstrated that low-affinity BCR interactions with auto-antigens, such as phosphatidylcholine (PtC), are positively selected (Chen et al. 2013; Iacovelli et al. 2015); secondly, BCR signaling in response to such antigens accelerated CLL development, indicating that BCR signaling triggered by external (auto antigen increases the aggressiveness of the disease.
In response to such criticism, the church pulled back.
In response to such integrative approaches Curzer (2014) hangs back.
In recent years there have been increasing calls for another institutional reform in response to developments such as the digital economy, climate change, migration and terrorism.

Such modular systems would be more flexible than current solutions and could be readily upgraded or adjusted in response to new developments in sequencing technology.
The members of ACS and ACO gene families are differentially expressed in development or in response to stimuli such as germination, leaf senescence and flower abscission, fruit ripening, wounding, flooding, exposure to ozone, touch, hormone treatment, and pathogen attack [ 28- 33].
But the nature of our leadership must also change in response to these policy developments.
