Ribonucleotide reductase: regulation, regulation, regulation

Trends in Biochemical Sciences, 1992
Ribonucleotide reductase (RNR) catalyses the rate limiting step in the production of deoxyribonucleotides needed for DNA synthesis. It is composed of two dissimilar subunits, R1, the large subunit containing the allosteric regulatory sites, and R2, the small subunit containing a binuclear iron center and a tyrosyl free radical.

On the Sample Complexity of the Linear Quadratic Regulator

Foundations of Computational Mathematics, 2017
This paper addresses the optimal control problem known as the linear quadratic regulator in the case when the dynamics are unknown. We propose a multistage procedure, called Coarse-ID control, that estimates a model from a few experimental trials ...

Regulating the regulators

Science, 2017
Autoimmunity Inhibitory receptors on T cells, including LAG3 (encoded by lymphocyte-activation gene 3 ), limit immune-mediated damage to the host. LAG3 is expressed by exhausted conventional T cells in the tumor microenvironment. The role of LAG3 in regulatory T cells (Tregs) has remained unclear.

Self-regulation

2017
Self-regulation encompasses a wide range of arrangements, from private ordering without resort to legal rules to state-enforced systems of delegated rules. Transaction cost analysis has been used to explain how private ordering emerges, and the advantages, but also the difficulties, of state delegation have been illustrated using a comparative approach.

TGF-beta: a master immune regulator

Expert opinion on therapeutic targets, 2020
Introduction: Transforming Growth Factor-Beta (TGF-β) is a master regulator of numerous cellular functions including cellular immunity. In cancer, TGF-β can function as a tumor promoter via several mechanisms including immunosuppression. Since the immune
