Abstract: This volume explores the latest advancements in the field of optogenetics and how it uses cellular light-sensing components and genetic engineering to control proteins and biological processes. The book chapters are organized into four parts. Part One focuses on intracellular optogenetic components for control of specific cell functions; Part Two looks at externally supplied light regulators that do not require genetic manipulation of target cells; Part Three highlights optogenetic control of organelles, and Part Four introduces technical tools required for light induction in optogenetic experiments, as well as a method for performing and analyzing optogenetic cell-cell adhesion. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and practical, Optogenetics: Methods and Protocols is a valuable resource to help researchers understand and apply the concepts of optogenetics and the underlying bioengineering principles, and establish the required technical light-illumination setups for administering light inputs and analysis of experimental outcomes.

Abstract: The Islets of Langerhans reside within the endocrine pancreas as highly vascularised micro-organs that are responsible for the secretion of key hormones, such as insulin and glucagon. Islet function relies on a range of dynamic molecular processes that include calcium (Ca2+) waves, hormone pulses, and complex interactions between islet cell types. Dysfunction of these processes results in poor maintenance of blood glucose homeostasis and is a hallmark of diabetes. Very recently, the development of optogenetic methods that rely on light-sensitive molecular actuators has allowed perturbing islet function with near physiological spatio-temporal acuity. These actuators harness natural photoreceptor proteins and their engineered variants to manipulate mouse and human cells that are not normally light-responsive. Until recently, optogenetics in islet biology has primarily focused on hormone production and secretion; however, studies on further aspects of islet function, including paracrine regulation between islet cell types and dynamics within intracellular signaling pathways are emerging. Here, we discuss the applicability of optogenetics to islets cells and comprehensively review seminal as well as recent work on optogenetic actuators and their effects in islet function and diabetes mellitus (DM).
